| 1 | Induction of HSF1 expression is associated with sporadic colorectal cancer显示文摘AIM: To explore the activation of signal b-ansduction pathways related with the carcinogenesis of sporadic colon cancers. METHODS: A gene array monitoring the activation of 8 signal transduction pathways (PathwayFinder GEArray) was used to screen the differentially expressed genes between colorectal cancer and normal colon tissues. The differentially expressed genes were further analyzed by RT-PCR, using RNA derived from colorectal cancer and normal colon tissue of 35 patients.RESULTS: The expression of HSF1, HSF27, HSP90 and iNOS was increased in colon cancer tissues compared to normal colon tissue using PathwayFinder GEArray. The RT-PCR results showed that the expression of HSF1 was increased in 86% (30/35) patients and the expression of iNOS was increased in 63% (22/35) patients.CONCLUSION: The induction of HSF1 gene expression is associated with sporadic colon cancer. HSF1 induces heat shock stress signaling pathway, which might play a role in the carcinogenesis of sporadic colorectal cancer. | HuiCen ShuZheng Yong-MingFang Xiao-PingTang QiDong | 2004 | World Journal of Gastroenterology2004，10，21： | 14 |
