Abstract
The activation of mammalian target of rapamycin (mTOR) signaling pathway in endometrial carcinoma cells Ishikawa and HEC-1A was investigated. The expression of mTOR was detected by confocal fluorescence microscopy in Ishikawa and HEC-1A cells. The mRNA levels of PTEN and mTOR, the downstream substrate S6K1 and 4E-BP1 protein were assayed by RT-PCR and Western blot, respectively. The expression of PTEN in Ishikawa cells was deficient, but intact in HEC-1A cells respectively (P<0.01). There was mTOR expression in both Ishikawa and HEC-1A cells and the phosphorylated substrate levels in Ishikawa cells were higher than those in HEC-1A cells (P<0.05). mTOR signaling pathway is activated in two endometrial carcinoma cell strains and the status of activation is related with PTEN expression of the cells. The activation level of mTOR is higher in PTEN-deficient endometrial carcinoma cells than that in PTEN-intact endometrial carcinoma cells.
