Is pEA3 the second Ets family transcription factor involved in tumor progression in ovarian carcinoma?
To the best of our knowledge, this is the first evidence associating PEA3 mRNA expression and poor survival in human epithelial malignancy. PEA3 is thus a novel prognostic marker in advanced-stage ovarian carcinoma. The association between PEA3 mRNA expression and the expression of the beta(1) integrin subunit, basic fibroblast growth factor, and EMMPRIN, first documented in our patient cohort, points to the central role of this transcription factor in tumor progression in ovarian carcinoma.
These findings suggest that exogenous 14,15-EET has potent inhibitory effect on proliferation, and could induce apoptosis in Tca-8113 cell, and these changes are related to the expression of PPARγ, the activation of EGFR, ERK, and PI3 kinase/AKT proteins.
