The individual PDAC cell lines, Colo357wt and Panc89, were established from lymph node metastases of pancreatic carcinoma patients and were presents from Dr. R Morgan and Dr. T Okabe, respectively. PancTuI cells were established from a ductal pancreatic carcinoma and were provided by Dr. M von Blow. Stably transfected Colo357/TRAF2 and Colo357/Bcl xL were established in our laboratory previously. All cells were grown in RPMI 1640 medium supplemented with ten percent fetal calf serum, 2 mmol/L glutamine, purchase Lenalidomide and 1 mmol/L sodium pyruvate in a humidified atmosphere with 500 CO2. Pre incubation with pharmacological inhibitors to block signal transduction before challenge of the cells with TRAIL was performed analogously as previously described. Total cellular RNA was isolated from the pancreatic cancer cell lines using RNAPure and a total RNA isolation system. cDNA was synthesized from total RNA utilizing a first strand cDNA synthesis kit. Real time PCR was used to amplify specific target sequences from cDNA arrangements as previously described utilizing the iCycler Real Time PCR Detection System and iQ SYBR Green Supermix with premixed PCR reagents. Data were analyzed using SPSS 14. 0. Continuous variables were expressed because the mean_standard deviation. Differences between groups were assessed using a proven way ANOVA test and impartial sample t test. P values significantly less than 0. 05 were considered statistically significant. Realtime PCR was performed to find expression of uPA and IL 8 in Colo357wt, Panc89, and PancTuI cells after Cellular differentiation treatment with different levels of TRAIL for 4 hours. All three cell lines exhibited measure dependent, TRAIL induced expression of uPA and IL 8, with the best quantities of uPA and IL 8 expression found in a reaction to 200 ng/mL TRAIL. A greater increase was exhibited by colo357 cells in the expression of uPA and IL 8 caused by TRAIL than the other two cell lines. TRAIL induced apoptosis was almost totally inhibited when TRAIL R1, or both TRAIL R1 and TRAIL R2, were plugged with antagonistic antibodies. No effect on TRAIL induced apoptosis was seen, when only TRAIL R2 was plugged. Curiously, TRAIL induced expression of uPA and IL 8 was also mediated via TRAIL R1, as shown by Crizotinib clinical trial real-time PCR. Conversely, TRAIL induced expression of uPA and IL 8 was slightly improved when TRAIL R2 was blocked. When TRAIL R1 and TRAIL R2 were blocked simultaneously in both Colo357 cells and Panc89 cells, TRAIL induced expression of uPA and IL 8 was almost completely inhibited. TRAF2 has been proven to be concerned in the non apoptotic signaling of death receptors. Thus, in this study the effect of TRAF2 on TRAIL mediated expression of uPA and IL 8 was examined. TRAIL treatment induced strong upregulation of the expression of uPA and IL 8 in Colo357 cells stably expressing TRAF2. The upregulation relative to the corresponding get a handle on cells was 11 fold for uPA and 5 fold for IL 8.
