While TPα was more variably expressed than TPβ in PCa, increased/high TPα expression within the tumour also trended toward increased BCR and shorter disease-free survival time.
Expression of TPα correlated with increasing prostate and breast tissue tumor grade while the TXA(2) mimetic U46619 promoted both proliferation and migration of the respective prostate (PC3) and breast (MCF-7 and MDA-MD-231) derived-carcinoma cell lines.
Expression levels of both C/EBPalpha isoforms, C/EBPbeta isoforms LAP1, LAP2 (liver-enriched transcriptional activating proteins), and LIP (liver-enriched transcriptional inhibitory protein), and C/EBPdelta in the tumors were correlated with clinicopathological tumor parameters, expression of estrogen and progesterone receptors (ER, PR), Ki67 immunostaining, and expression of seven cell-cycle regulatory proteins which had been analyzed before.
