Article Title: Antitumor Effects of a Sirtuin Inhibitor, Tenovin-6, against Gastric Cancer Cells via Death Receptor 5 Up-Regulation
doi: 10.1371/journal.pone.0102831
Figure Lengend Snippet: A: Time-course analysis of the expression of p53, its downstream molecule p21 Waf/Cip1 , and apoptosis-related molecules in gastric cancer cells treated with tenovin-6 (10 µM). Relative intensity of the proteins' expression is shown in . Tenovin-6 induced the expression of Ac-p53 and p21 Waf/Cip1 , but not Bcl-2. DR5 expression was strongly induced by tenovin-6. TRAIL, and cleaved PARP were slightly increased, but FADD expression was not affected. A doublet of DR5 shows its precursor (upper band) and mature isoforms (lower band). B: Four cell lines were treated with tenovin-6 (10 µM) or a vehicle control for 72 h, double-stained with FITC-annexin V and PI, and analyzed by flow cytometry. The statistical significance of differences between groups was evaluated using Student's t-test. * p <0.01; ** p <0.05.
