The aim of the present study was to examine mRNA expression levels of Th1 (TNF-alpha , IFN-gamma, and IL-12p40) and Th2 (IL-6 and IL-10) cytokines for any association with clinicopathological characteristics of epithelial ovarian cancer. mRNA was isolated, and cDNA prepared from 40 samples of epithelial ovarian cancers.
33 of 40 genes were also significantly correlated in low malignant potential (LMP) EOCs, while 7 genes, named C5AR1, FPR1, G0S2, IL8, KLF2, MMP19, and THBD were IL6-correlated only in advanced stage EOCs.
More importantly, we demonstrate that Bcl<sub>xl</sub> expression levels in EOC cells is dynamic and can be regulated by microenvironments that are enriched with the pro-inflammatory cytokine IL-6 such as the cancer stem cell and adipocyte niches.
The colorimetric method was used to determine levels of the markers 8-isoprostanes (8-IP), lipid peroxidation products (LPO), and total antioxidant capacity (TAC) in plasma and ascites fluid; and with ELISA, the levels of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-<i>α</i>) were determined in patients with EOC.<i>Results</i>.
