TR4 contributes to the chemoresistance in PCa stem/progenitor cells through up-regulation of Oct4 and IL1Ra expression. qPCR (a) and Western blot (b) analysis results show high expression of Oct4 in C4-2/CD133+ stem/progenitor cells. c, expression of TR4, Oct4, IL-1Ra, and several taxel-related chemoresistance genes in PCSC-siTR4 and PCSC-sc cells. qPCR (left) and Western blot analysis (right) are shown. d, qPCR (left) and Western blot (right) results showing expression of Oct4, IL-1Ra, and several taxel-related drug resistance genes in TR4 knockdown C4-2/CD133+ PCa stem/progenitor cells. *, p < 0.05.
