Five-year overall survival is 75%. Comparison with a previous study without rituximab shows improvement of outcome (median VX-809 research buy event-free survival, 51 vs 83 months). No toxic death or unexpected toxicities were observed. This study confirms that induction with rituximab and cytarabine-based regimens is safe and effective in MCL patients. This regimen is currently compared with R-CHOP21 induction in a multicentric European protocol. (Blood.

“Kim SY, Song SY, Kim MS, Lee JY, Lee HM, Choi HY, Yoo NJ, Lee SH. Immunohistochemical analysis of Fas and FLIP in prostate cancers. APMIS 2009; 117: 28-33.\n\nFas-mediated apoptosis is considered a principal pathway for apoptosis induction in normal and cancer cells. Expression of Fas has been reported in prostate tissues several times, but the data were not consistent. Expression of FLICE-like inhibitory protein (FLIP), an inhibitor of Fas-mediated apoptosis, has not been studied by immunohistochemistry in prostate tissues. The aim of this study is to explore whether alterations of Fas and FLIP expression occur in prostate cancer tissues. selleck screening library We analyzed the expression of Fas and FLIP in 107 prostate adenocarcinoma tissues by immunohistochemistry using a tissue microarray approach. Normal glandular cells of the prostates strongly expressed both Fas and FLIP proteins. Prostate intraepithelial

neoplasm also showed a strong Fas immunoreacitity. Fas expression was strongly positive in 60 cancers (56.1%), but the remaining 47 cancers showed no (6.5%) or markedly decreased (37.4%) Fas immunostaining compared with the

normal glandular cells of the same patients. PP2 By contrast, FLIP expression was strong in most (103/107; 96.3%) of the cancers, and only four cancers (3.7%) showed decreased immunoreactivities compared with the normal cells. The decreased expression of Fas was not associated with pathologic characteristics, including FLIP expression, size of the cancers, age, Gleason score and stage. The decreased expression of Fas in a large fraction of prostate cancers compared with their normal cells suggested that loss of Fas expression might play a role in tumorigenesis in some prostate cancers possibly by inhibiting apoptosis mediated by Fas.”
“With the characterization of Sir2 gene in yeast aging, its mammalian homologs Sirtuins 1-7 have been attracting attention from scientists with various research backgrounds. Among Sirtuins, SIRT1 is the most extensively studied. Recent progress on mammalian Sirtuins has shown that SIRT6 as a histone deacetylase may also play a critical role in regulating mammalian aging. This review summarizes recent advances on SIRT6 as a key modulator of telomere structure, DNA repair, metabolism, and NF-kappa B pathway in aging. In addition, we discuss the challenges that remain to be studied in SIRT6 biology.”
