1 The effects and mechanisms of epirubicin treatment on the expressions of upstream survival signals (e.g., beta-catenin) and downstream MDR transporters (e.g., P-gp) and anti-apoptotic pathways (e.g., Bcl-2) were assessed with or without HuR knockdown (siHuR) or overexpression (overHuR; ectopic HuR or pcDNA3/HA-HuR). Epirubicin BCL2 apoptosis regulator Homo sapiens
2 Our results showed that siHuR decreased transcriptional expressions of galectin-3, beta-catenin, cyclin D1, Bcl-2, P-gp, MRP1, and MRP2 in epirubicin-treated colon cancer cells. Epirubicin BCL2 apoptosis regulator Homo sapiens
3 The combined treatments of siHuR and epirubicin significantly reduced the expression of Bcl-2, but increased the expression of Bax, as well as activity and expression levels of caspase-3 and -9. Epirubicin BCL2 apoptosis regulator Homo sapiens
