For each individual, blood samples were also taken from the heart

For each individual, blood samples were also taken from the heart or the thoracic cavity on a 1-cm2 Whatman blotting paper. All listed animal procedures were pre-approved by the Direction des Services Vétérinaires of the Herault Department (B 34-169-1 Agreement). PUUV serological screening and viral load Protein Tyrosine Kinase inhibitor quantification In the laboratory, each piece of Whatman blotting paper was placed in 1 ml phosphate-buffered saline. These diluted blood samples were screened for IgG antibodies to Puumala virus (PUUV) using immunofluorescence antibody test (IFAT)

as described in Lundkvist et al. [34]. PUUV load was measured in PUUV seropositive voles using real-time quantitative RT-PCR. Total RNA was extracted from lung tissue samples as PUUV concentration XMU-MP-1 mw is high compared to other organs [35]. We used TriPure Isolation Reagent (Roche) according to the manufacturer’s C59 wnt price instructions. One μg of RNA was used for first-strand cDNA synthesis using RevertAid™ H Minus Kit (Fermentas) with random hexamers. Real-time quantitative PCR was done using a DyNAmo Capillary SYBR Green Quantitative PCR kit (Finnzymes)

with a LightCycler instrument (Roche). The following primers (Oligomer) were used: PUUV-forward 5′-GAG GAT ATA ACC CGC CAT GA-3′, PUUV-reverse 5′-CTG GCT TGC AGT GTG TTT TT-3′. Samples were first normalized against variation in vole lung sample quality and quantity to GAPDH expression with the following primers: GAPDH-forward 5′-ATG GGG AAG GTG AAG GTC G-3′ and GAPDH-reverse GBA3 5′-TAA AAG CAG CCC TGG TGA CC-3′. We then provide an absolute quantification for PUUV RNA: PUUV copy numbers (copies per 1 μg of total RNA) were calculated from a standard curve created using 10-fold dilutions of in vitro transcribed PUUV S segment RNA (T7 transcription kit, Fermentas). Melting curve analysis was performed according to recommendations of the DyNAmo kit to confirm the specificity of positive samples. Samples were considered PUUV RNA positive when the C T (cycle threshold) value was lower than 40 cycles and

the melting curve showed a specific product. Statistical analyses A logistic regression was first applied to determine vole individual characteristics that best explained PUUV infection. The dependent variable was the presence/absence of anti-PUUV antibodies in voles. Sex, sexual maturity, mass, body condition, landscape and site nested within landscape were included as independent variables. All possible two way interactions were considered. Model selection was performed using the Akaike’s Information Criterion [AIC, [36, 37]]. The model with the lowest AIC value was viewed as the most parsimonious one, i.e. the one explaining most of the variance with the fewest parameters [36]. Nested models with difference of AIC <2 compared to the model with the lowest AIC were selected.

A large difference in the

blue versus red light harvestin

A large difference in the

blue versus red light harvesting for PSII is apparent between algae and cyanobacteria when comparing absorption in Fig. 1 to the PSII fluorescence in Fig. 2. The prominent role of Chla in light harvesting for PSII in algae, visible in the blue around 440 nm, is nearly absent in the Target Selective Inhibitor Library cyanobacterial strains, where only a small share of Chla is connected to PSII (Johnsen and Sakshaug 1996, 2007). The algal species further reveal light harvesting for PSII in the area of maximum absorption by accessory pigments in the learn more 460–480 nm range: fluorescence resulting from excitation at 470–480 and at 650 nm in B. submarina may be attributed to Chlorophyll b, whereas in T. pseudonana, excitation at 460–470 and 630 nm would be due to Chlorophyll c and excitation at 530–540 nm due to fucoxanthin. Between the two algal species, affinity for red light was higher in B. submarina, in some cases exceeding fluorescence from

red excitation found in cyanobacterial cultures that were nutrient starved. The Chla fluorescence excitation features found in the cyanobacterial cultures matched the absorption peaks of phycobilipigments given above. Between the cyanobacterial cultures Nodularia showed the highest absorption-normalized fluorescence under blue illumination. Cyanobacteria with urobilin-rich phycoerythrin, which may absorb short-wavelength light down to 490 nm and are common in see more Megestrol Acetate clear water environments, were not included in our data set. The variability in F v/F m of the species used in this study is shown as histograms in Fig. 3. The excitation bands to describe F v/F m in algae and cyanobacteria were selected to match peak areas in the excitation spectra (Fig. 2). F v/F m of the algae is shown for excitation at 470 nm, cyanobacterial F v/F m at 590 nm (both for 10-nm bandwidth). The emission was measured at 683 nm (10-nm bandwidth) for

both groups. Maximum F v/F m in the order of 0.65 are common in phytoplankton studies (but see Samson et al. 1999; Suggett et al. 2004; Vredenberg et al. 2009). The majority of cultures included in our analyses showed F v/F m in the 0.45–0.65 range, while the range of F v/F m in cyanobacterial cultures was wider (0.1–0.7) than that of algal cultures (0.4–0.7). The top range of these F v/F m values measured in cyanobacteria exceed those commonly found in literature, where values for healthy cultures are usually in the 0.3–0.5 range (but see Raateoja et al. 2004; Suggett et al. 2009). Lower F v/F m in cyanobacteria has been attributed to incomplete saturation of PSII in FRRF studies (Raateoja et al. 2004), and to dampening of the variable fluorescence by an offset of F 0 caused by fluorescing phycobilipigments (Campbell et al. 1996, 1998), which is discussed further below. Fig. 3 Histograms of F v/F m for the cultures used in this study.

This might explain why we were not able to demonstrate protective

This might explain why we were not able to demonstrate protective effects of IPC and IPO as buy MK-8931 judged by liver parameters, i.e., the duration of ischemia was too short. Furthermore, 30 min of reperfusion might be 4SC-202 datasheet too short follow up to demonstrate the full extent of the I/R injuries. The cytoprotective effect of IPO, defined as brief periods of ischemia and reperfusion after liver ischemia, is less well established [15, 16]. In the present study, we could

not demonstrate any hepatoprotective effects of IPO assessed by liver parameters, and we speculate that the explanation may be the same as above. We choose the actual time protocol with 30 minutes of ischemia because we wanted to create a setting relevant for normal clinics. Even though longer periods of liver ischemia have been safely applied, most surgeons would be reluctant to induce more than 30 minutes of ischemia on the liver. The mechanisms responsible for the protective effects of IPC and IPO are only partially understood. In the present study, IPC

resulted in a significantly lower expression of HIF-1α mRNA compared with rats subjected to liver ischemia without IPC. This leads us to conclude that HIF-1α, in our model of modest I/R-injuries, does not seem to be a mediator of the cyto-protective effects of IPC. In rats subjected to IPO there was a tendency towards lower HIF-1α mRNA expression, although not significant, when compared to the sheer liver ischemia group. This indicates that HIF 1α is not involved in the cytoprotective effects of IPO. In this sense, the HIF-1α mRNA response could to be a marker of the degree of I/R injury, BCKDHA i.e., the CP673451 mouse higher HIF-1α mRNA response after ischemia,

the more pronounced I/R injuries. Further studies need to be performed to address this issue, but it is first and foremost supported in a study by Cursio et al., where they showed that the expression of HIF-1 and the degree of apoptosis was increased in rats subjected to 120 min of warm liver ischemia compared to non-ischemia [32]. Another study supporting the conclusion in the present paper is that by Feinman et al. [33]. They used partially HIF-1 deficient mice in a hemorrhagic shock model and concluded that HIF-1 activation was necessary for ischemic gut mucosal injury. The expression of VEGF mRNA was regulated upwards by the ischemic episodes in the group subjected to sustained ischemia and in the IPC+IPO group. A higher expression of VEGF in the group with liver ischemia only, correlates with the elevated HIF-1α expression in this group. TGF-β expression levels were not affected in any of the groups. Both VEGF and TGF-β are, as previously described, genes that are regulated downstream of HIF-1α. However, as this study only focuses on the expression levels after 30 min of reperfusion, we cannot be sure that we are measuring the full effect of the changed HIF-1α levels.

The sections were incubated in a 3, 3-diaminobenzidine solution, counterstained with hematoxylin, dehydrated

in ethanol, Selleckchem TGFbeta inhibitor cleared in xylene, and coverslipped. Negative controls were treated in all assays (with the omission of primary antibodies). The sections were visualized using microscopic observation. Evaluation of the immunohistochemical findings IHC staining was assessed by two independent pathologists without knowledge of the clinical and pathologic features of the cases. A negative control array was concurrently undertaken showing < 1% nuclear staining in all specimens. All specimens were evaluated according to the 0–4 grading criteria (based on the percentage of 5-hmC-positive cells) and 0–3 grading criteria (based on the staining intensity) [11]. The 5-hmC score was calculated as the score of the cell count × the score of intensity. The median 5-hmC score was used as a cut-off in subsequent analyses. For IDH2 quantification, BI 2536 nmr photographs of three representative fields were captured under high-power magnification (200×) using Leica Qwin Plus v3 software; identical settings were used for each photograph. The 5-hmC and IDH2 density were counted using Image-Pro Plus v6.2 software (Media Cybernetics Inc., Bethesda, MD). The

integrated optical density of the CB-839 price area positively stained for IDH2 in each photograph was calculated, and its ratio to the total area of each photograph was considered to be the IDH2 density. The median IDH2 density was used as a cut-off in subsequent analyses. Statistical analysis The data were analyzed with SPSS 19.0 software, as previously described [23]. A P value <0.05 was considered statistically significant. Results Immunohistochemical features in TMA Using hematoxylin and eosin staining, the cancer cells were found to be relatively homogenous within a tumor (excluding necrotic,

DNA ligase hemorrhagic, and fibrotic components). Representative cases of immunohistochemical staining are shown in Figure 1. We observed 5-hmC staining primarily on the nuclei of the tumor cells and hepatocytes; IDH2 staining was observed primarily in the cytoplasm of the HCC cells. Most of the stromal cells were negatively stained, although sporadic positive staining of these cells was observed. Figure 1 Expression of 5-hmC and IDH2 in HCC samples (training cohort, n = 318). Representative HCC tumor samples show the expression of 5-hmC (brown in the nucleus of HCC cells) and IDH2 (brown in the cytoplasm of HCC cells). Scale bar, 200×, 200 μm. Correlations of 5-hmC and IDH2 expression with clinicopathologic characteristics The correlations of 5-hmC and IDH2 expression with the clinicopathologic characteristics are shown in Table 1 and Additional file 2: Table S2. In the training cohort, 5-hmC expression correlated with sex (P =0.007) and AFP (P <0.001). IDH2 expression only correlated with tumor differentiation (P =0.017) (Table 1).

0, CapitalBio). Signal intensities for each spot were calculated by subtracting local background from total intensities. Raw data were normalized and analyzed using the Significance Analysis of Microarrays (SAM, version 2.1, Stanford University, CA, USA) software [25]. The raw data was Log2 transformed and median centered by arrays and genes using the adjust data function of CLUSTER 3.0 software for cluster analysis [26]. Stem-loop qRT-PCR for miRNAs All miRNA-specific primers were designed mTOR activation according to miRNA sequences. The universally expressed U6 was used as an internal control. Reverse transcriptase reactions contained 2.5 ng/μL purified total RNA, 50 nM stem-loop reverse

transcription (RT) primer, 1 × RT buffer, 0.25 mM of each of dNTPs, 3.33 U/ml MultiScribe reverse transcriptase, 0.25 U/ml RNase inhibitor. The 7.5 μL reactions were incubated in an MJ Research PTC-225 Thermocycler for 30 min at 16°C, 30 min at 42°C, 5 min at 85°C, and then held at 4°C. All reverse transcriptase reactions were run in duplicate. Stem-loop qRT-PCR was performed as described in published references [27]. The 10 μl PCR reaction contained 0.67 μl RT product, 1 × PCR Master Mix, 1.5 μM forward primer, and 0.7 μM reverse primer. The reactions were incubated

at 95°C for 10 min, followed by 40 cycles of 95°C for 15 s and 60°C for 1 min. All reactions were run in triplicate. Melting curves were performed using Dissociation Curves software (Funglyn) to ensure only a single product was amplified, and Protein Tyrosine Kinase inhibitor the specificity of samples was confirmed by running on a 3% agarose gel. All reagents from MBI Company (MBI Fermentas, Maryland, USA) were used following the manufacturer’s protocols. Results The effect of DMBA-induced oral carcinogenesis Two animals died during the experimental period (one each from Groups A and B). Histologically, all samples

from Group C appeared normal, with a thin epithelium devoid of rete ridges (PLX3397 supplier Figure 1A~C). Five animals from Group A and seven animals from Group B developed SCC (Figure 1D~F). The tumor diameters ranged from 1.5 mm to 15 mm in both groups, with an average diameter of 5 ± 1.69 mm and 8.7 ± 2.55 mm for Molecular motor Group A and B, respectively (Table 1). Most of the squamous cell carcinomas were classified as well-differentiated or moderately differentiated. Figure 1 DMBA-induced oral carcinogenesis in the hamster cheek pouch (H&E staining). (A~C) Normal epithelium; (D) SCC; (E) Papillary SCC; (F) SCC. miRNA microarray analysis RNA gel electrophoresis demonstrated that the quality of the RNA was good. SAM was performed to identify differences in miRNA expression between cancerous and normal samples. SAM calculated a score for each gene on the basis of the change in expression relative to the S.D. of all measurements. The SAM data indicated that 5 miRNA genes were significantly overexpressed and that 12 miRNA genes were significantly underexpressed in cancer samples, with fold changes>2.

5 mg

5 mg testosterone complexed ATM Kinase Inhibitor with hydroxypropyl-β cyclodextrin. All 13 subjects received the investigational drug formulation in random order. Wash-out between treatments was at least 7 days. Subjects had serial blood samples drawn via an intravenous EPZ-6438 datasheet catheter. Pharmacokinetic parameters were monitored at baseline (−10 min) and (at 5, 10, 15, 20, 25, 30, 60, 90, 120, 135, 145, 165, 180, 195, 210, 225, 240, 270, 300, 330, 360, 390, 450, 570, 690, 810, 930, 1,590 min) after dosing. Measurement of total testosterone, free testosterone, and dihydrotestosterone were performed at −10, 5,

10, 15, 20, 25, 30, 60, 90, 120, 145, 180, 240 and 1,590 minutes after dosing; buspirone and metabolite 1-(2-pyrimidinyl)-piperazine at −10, 10, 30, 60, 90, 120, 135, 145, 165, 180, 195, 210, 225, 240, 270, 300, 330, 360, 390, 450, 570, 690, 810, 930, 1,590 minutes after dosing. For each admission period,

subjects were instructed to come to the study site on the evening prior to dose administration where vital signs were checked (including ECG) and urine drug test, pregnancy test, and alcohol breath analysis were performed. During the admission period, the subjects received low calorie meals on site and decaffeinated coffee and tea to minimize the influence on pharmacokinetic parameters. Drug, alcohol, and pregnancy tests were performed prior to experimental sessions. 2.3 Medication and Dosing The combination tablet is a menthol-flavored white tablet of 9 mm in diameter for sublingual administration followed by oral administration. The quickly dissolving outer coating, applied by film coating the tablet, delivers cyclodextrin-complexed testosterone (0.5 mg) sublingually, CB-839 cost and the time-delayed-release core delivers buspirone (10 mg) 2.5 hours later. The outer coating comprises testosterone, excipients, and a menthol flavor to guide the disappearance of the coating. The testosterone coating is designed to fully dissolve and Clomifene to obtain a fast and complete absorption via the mucosal membranes under the tongue. The time-delayed-release core containing the buspirone has been designed

on the basis of in-vitro release studies of US Pharmacopeia (USP) II and III, to release the buspirone in a pulsatile manner, approximately 2.5 hours after oral administration. This method of release is accomplished through the use of a polymer coating of ethylcellulose which allows for a slow permeation of water in a pH-independent manner. At the predetermined time, the polymer coating ruptures at the edge of the tablet. The complete disintegrated core of the inner tablet is released immediately, after which there is no delay for the dissolution of the buspirone in the surrounding fluid. The two formulations were administered by a trained research associate and controlled by a second research associate. For the testosterone component of F1, a 1 mg/mL testosterone cyclodextrin complex solution was used; the solution was administered with a micropipette (e.g.

The large majority of isolates clusters into two lineages, but tw

The large majority of isolates clusters into two lineages, but two additional lineages have been identified. However, these lineages correspond more to different but overlapping buy ICG-001 niches than to virulence-related clusters. We previously described low-virulence L. R788 in vivo monocytogenes strains using a method that combines a plaque-forming (PF) assay with the subcutaneous (s.c.) inoculation of mice [3]. Using the results

of cell infection assays and phospholipase activities, the low-virulence strains were assigned to one of four groups by cluster analysis. Sequencing of virulence-related genes highlighted the molecular causes of low virulence. Group I included strains that exhibited two different types of mutation in the prfA gene: either a single amino acid substitution, PrfAK220T, or a truncated PrfA, PrfAΔ174-237 [7]. In Group III, strains exhibited the same mutations in the plcA, inlA and inlB genes that lead to a lack of InlA protein, an absence of PI-PLC activity and a mutated InlB [8]. The fact that numerous strains exhibit ABT-888 cost the same substitutions in virulence genes suggests that they could have common evolutionary pathways. In contrast, Ragon et al. reported that numerous L. monocytogenes strains exhibit

different mutations in the inlA gene due to convergent evolution [9].

These data emphasize the interest of providing a framework for the population study based on the virulence of this bacterium. The aim of this study was to assign the new low-virulence strains identified by different methods to phenotypic and genotypic Groups using cluster analysis, and to study their relatedness with virulent Listeria monocytogenes strains using pulsed-field gel electrophoresis Clomifene and multi-locus sequence typing analyses Results Phenotypic characterisation of the low-virulence strains The combination of PF assays followed by s.c. injections of immunocompetent mice, allowed us through different studies, to collect 43 low-virulence strains mainly of serotypes 1/2a (51%) and 4b (28%), which are usually related to sporadic and epidemic human cases of listeriosis, respectively [4] (Table 1). In this study, a strain is considered a low-virulence strain when fewer than 4 mice out of 5 inoculated become infected with a mean number of bacteria in the spleen less than 3.45 ± 0.77 log [3].

Scenario (d) was followed by (c) for several times. Scheme not to scale Harlequin frogs (Atelopus) are a species-rich

bufonid genus of Andean origin, with more than 100 species occurring in forest or paramo habitats in the Andes (Lötters 1996; La Marca et al. 2005). In this paper we focus on the less than 10 Atelopus (depending on the taxonomy applied; see Lötters et al. 2002) occurring exclusively in forest habitats in the Amazon basin and on the eastern Guiana Shield. In an earlier molecular genetic study, Noonan and Gaucher (2005) showed that the five nominal species of the eastern Guiana Shield harlequin frogs are genetically little differentiated and that they Stattic mw apparently interbreed in nature. Supported by divergence time estimates, these authors advocated that the observed phylogeographical

patterns in Atelopus fit DV predictions, i.e. that a single Andean ancestor had invaded the eastern Guiana Shield (likely in late Miocene, as also suggested for other anuran amphibians; Santos et al. 2008) and has started speciation there in the Pleistocene due to the alteration of glacial and interglacial phases (as illustrated in Fig. 1a–d). To their molecular phylogeny, Noonan and Gaucher (2005) added only four Atelopus species from outside the eastern Guiana Shield. As a result, the validity of their study is pending on additional corroboration. This is especially significant because this website our knowledge on the current

distribution of harlequin frogs in central Amazonia is poorly understood. Lescure and Gasc (1986), with providing data, proposed a continuous distribution of harlequin frogs from the Andes to the eastern Guiana Shield. In contrast, Lötters et al. (2002), in a taxonomic study, were unable to trace Atelopus material in scientific collections from a large part of central Amazonia, casting some doubt on a continuous distribution. Such a hiatus could be well explained by DV predictions, since the old recolonisation of central Amazonia, either from the western Amazonian lowlands or from the eastern Guiana Shield plus vicinities, would be impossible during the current postglacial. From a phylogenetic point of view, according to DV predictions and the findings of Noonan and Gaucher (2005), we expect that harlequin frogs from east of this suspected distribution gap in central Amazonia constitute one clade nested within those from the Andes and Amazonian lowlands adjacent to them (Fig. 1d) if more species were included from more of the genus’ entire see more geographic range than available to Noonan and Gaucher (2005). Species can respond to climate change in two ways. One is change of geographic range (i.e. increase, decrease down to extinction, shift) and maintenance of the specific climate envelope, termed niche conservancy (e.g. Peterson et al. 1999; Wiens and Graham 2005).

Since E coli fabZ null strains are nonviable [15, 16], we first

Since E. coli fabZ null strains are nonviable [15, 16], we first introduced pHW22 into strain

DY330, a “”recombineering”" strain [17]. We then expressed the C. acetobutylicium FabZ in this strain and used standard phage γ recombinase manipulations to delete the host fabZ gene. These manipulations gave strain HW7, which grew well in VX-689 solubility dmso presence of arabinose but failed to grow in the presence of fucose, an anti-inducer of C59 wnt order arabinose promoter expression (Fig. 4). The fatty acid composition of the complemented mutant strain grown in presence of arabinose was similar to that of the parental strain, DY330, indicating that C. acetobutylicium FabZ functionally replaced E. coli FabZ (Table 3). The lack of fabA and fabM homologues in C. acetobutylicium raised the possibility that the FabZ of this organism might function as both an isomerase and a

dehydratase as does the E. faecalis FabZ-like protein, FabN [9]. To test this possibility plasmid pHW22 was introduced into both the fabA(Ts) E. coli strain CY57 and the fabA null mutant strain MH121. Neither stain grew in the absence of unsaturated fatty acid supplementation (data not shown) indicating that C. acetobutylicium FabZ lacks isomerase function and thus was unable to functionally replace FabA. However, it remained possible that C. acetobutylicium FabZ catalyzed UFA synthesis, but that the levels of UFA produced were too low to support growth. This possibility was tested by [14C]-acetate labeling of the fatty acids synthesized by strain CY57 carrying pHW22 and analysis of the resulting BIBF 1120 solubility dmso radioactive fatty acids for traces of UFA (Fig. 5). No UFA synthesis was detected. Another possible explanation for the observed lack of UFA synthesis was that FabI, the enoyl-ACP reductase of E. coli, converted

the intermediate trans-2-decenoyl-ACP to decanoyl-ACP before the putative isomerase activity of C. acetobutylicium FabZ could act. Thus, we repeated the labeling experiment in the presence acetylcholine of a low dose of triclosan, a specific E. coli FabI inhibitor [6], in order to give the putative isomerase a better opportunity to act on the trans-2-decenoyl-ACP intermediate. Again no synthesis of unsaturated fatty acid was observed (data not shown). These in vivo results argued strongly that that C. acetobutylicium FabZ was unable to isomerize trans-2-decenoyl-ACP.

The plates were of RB medium ei ther unsupplemented or supplemented with the inducer, L-arabinose, or supplemented with the anti-inducer, D-fucose, as shown. The plates were incubated at 30°C. Strain DY330 has the wild type fabZ locus whereas strain HW7 is ΔfabZ.

Renal cell carcinoma (RCC) is one of the most common genitourinar

Renal cell carcinoma (RCC) is one of the most common genitourinary malignancies, accounting for about 3% of all cancers worldwide [17]. With the improved imaging diagnostic technology, more RCC cases have been diagnosed at an early

stage. However, there is a considerable number of RCC patients at the time of diagnosis has been transferred [18]. Research efforts have found various biomarkers of diagnostic and prognostic of RCC such as hypoxia-induced factor 1alpha (HIF1α), vascular endothelial growth factor (VEGF), and CX-5461 molecular weight carbonic GSK872 solubility dmso anhydrase IX (CA9), but they are not specific and sensitive enough to accurately predict the survival of RCC patients [19–21]. Recent studies indicate that epigenetic alterations play an important role in carcinogenesis, and global histone modifications as predictors of cancer recurrence in various tumor entities has begun to study. Patients with RCC have been found that total acetylation levels of histone H3 were inversely correlated with pT-stage, distant metastasis, Fuhrman Histone Methyltransferase inhibitor grading and RCC progression, whereas total histone H4Ac deacetylation was correlated with pT-stage and grading [22]. All the above observations strongly suggest that histone modifications might be involved in the development and progression of RCC. However, it is not clear which

particular enzyme or specific modified lysine residue is responsible for tumorigenesis in RCC. This study aims to assess hMOF expression and its corresponding acetylation of histone H4K16 in the RCC via qRT-PCR, western blotting and immunohistochemistry. Simultaneously, Cobimetinib clinical trial we also investigated the correlation between the expression of hMOF and CA9. Materials and methods Materials Anti-H4K16 (Cat# H9164) polyclonal

antibody was purchased from Sigma. Anti-MYST1 (Cat# A300-992A) was obtained from Bethyl Laboratories. Anti-CA9 (Cat# sc-25599) was from Santa Cruz Biotechnology. Anti-GAPDH and anti-hMOF rabbit polyclonal antibodies were raised against bacterially expressed proteins (Jilin University). Tissue collection Human paired clinical RCC tissues and matched adjacent tissues were collected from patients with primary RCC between March 2011 and May 2012, who underwent kidney tumor radical surgery at the First Hospital of Jilin University. The study was approved by the Ethics Committee of the First Hospital of Jilin University and all patients gave informed consent. All removed tissues during the surgery were frozen immediately in liquid nitrogen and then stored at −80°C. Patient medical records including tumor staging, pathological diagnosis, and surgical records were reviewed. The pathologic diagnosis of the resected tumors was based on the American Joint Committee on Cancer [23]. All patients did not receive chemotherapy or radiotherapy before surgery.
