This journal is a member of and subscribes to the principles of the Committee on Publication Ethics. The sod2 promoter is hypermethylated in some pancreatic carcinomas that is inversely correlated with protein levels.
Survival (%) of Caco-2 (closed square), Colo320 (closed triangle) and SW948 (closed diamond), after continuous incubation with (A) rhTRAIL and (B) anti-CD95 as measured by cytotoxicity assays. Reverse transcription–PCR of TRAIL and TRAIL receptors in Caco-2, Colo320 and SW948, as described in the Materials and Methods. Basic membrane expression of the TRAIL receptors DR4, DR5, DcR1 and DcR2 and the CD95 receptor in Caco-2, Colo320 and SW948 as determined by flow cytometry. Anti-CD95-mediated apoptosis in Caco-2, Colo320 and SW948 with or without 24 h incubation with interferon- (IFN).
Western blot analysis of PARP-cleavage in Caco-2, Colo320 and SW948 after exposure to cycloheximide (CHX), anti-CD95 or cycloheximide in combination with anti-CD95. Active caspase-3 activity was estimated by western blotting using equal amounts (40 g) of whole-cell lysates.


In a viable cell, the pro-apoptotic Bcl-2 family members (Bax, Bak) and BH3-only proteins, such as Bad, are antagonized by anti-apoptotic members, such as Bcl-XL, Bcl-2. Cells were incubated as control in medium (black bars), cycloheximide (light grey bars), anti-CD95 (dark grey bars), rhTRAIL (white bars) or combinations of cycloheximide with anti-CD95 (striped bars) or cycloheximide with rhTRAIL (spotted bars) as described in Materials and Methods. In response to an apoptotic stimulus, Bad are activated and prevent anti-apoptotic Bcl-2 members from inhibiting pro-apoptotic members. All CpG dinucleotides are represented by either an open circle () to indicate unmethylated cytosines or a filled circle () to indicate a methylated cytosine.
Exposure to 5-FU, cisplatin or interferon- did not change the percentage of receptor positive cells. Exposure to 5-FU, cisplatin or interferon- did not change the percentage at receptor positive cells. Increased CD95 expression was detected as an increased fluorescence intensity of the whole cell population and resulted in a peak shift to the right.
Cell survival in the control experiment performed by using Erb-hcAb as a single agent was at 82%.


Pro-apoptotic members then form pores into the mitochondrial membrane and release pro-apoptotic factors, such as cytochrome c into the cytosol, which subsequently activates the caspase cascade leading to apoptosis. The level of SOD2 expression is inversely correlated with the extent of hypermethylation, with Capan-1 showing the lowest level of methylation and the highest level of expression. Phosphorylation of Bad facilitates its binding with scaffolding protein 14-3-3 and, thereby, inhibits translocation of Bad to the mitochondria to deactivate the anti-apoptotic protein Bcl-XL. Cell survival in the control experiment performed by using Erb-hRNase as a single agent was at 67%.
Protein expression was corrected to actin expression and is expressed in relation to Caco-2 expression. Protein expression of cells incubated with cycloheximide is presented in relation to FLIP expression in the control cells.
