摘要: Background Bcl-XL, a mitochondria membrane protein, is overexpressed in colorectal cancers and promotes cell survival. We have previously shown that the adenovector expressing small hairpin (sh)RNA targeting Bcl-XL could induce significantly apoptosis colon cancer cells. In present study, we aimed to further detect anti-cancer effect of shRNA (Ad/Bcl-XL shRNA) on rectal xenografts were derived from patient tumors. Methods We first established three xenografts. These subsequently treated with Ad/Bcl-XL alone or combination 5-fluouracil (5-Fu). Finally, inhibition tumor growth, survival time induction analyzed. Results The results obtained demonstrated effectively suppress growth all prolong their time. After being combined 5-Fu, suppressing was enhanced further. addition, data also showed 5-Fu increase apoptotic ratio xenograft. Conclusions These indicate without has effective anti-tumor effects tumor-derived xenografts, suggesting it be potential strategy for therapy. Copyright © 2012 John Wiley & Sons, Ltd.
