Abstract
Abstract Tumor necrosis factor-alpha (TNF) and Ghrelin exhibit autocrine and paracrine functions and are present in several tissues. Their biological effects have been observed in the endometrium under both normal and pathological conditions. This experiment was set out to determine whether TNF alpha changes ghrelin expression in primary endometrial cell culture and endometrial cancer cell lines. Endometrial tissue was taken after ethical permission from 25–40-year-old women who had gynecological surgery at Jessop Hospital, Sheffield, UK. TNF- alpha was added to cultivated Ishikawa and HEC1B endometrial cancer cell lines at 1,10 ng/ml. similar treatments were conducted to isolate primary endometrial epithelial and stromal cells. TNF-induced Ghrelin expression was evaluated by immunocytochemistry. TNF induced a concentration-dependent increase in immunostaining of ghrelin expression and apoptosis in endometrial cancer cell lines. Similarly, primary endometrial epithelial showed a concentration-dependent increase in the apoptotic appearance and ghrelin expression, whereas stromal cells did not demonstrate any detectable changes. TNF-alpha showed a Concentration-dependent effect on apoptotic appearance and ghrelin-expressing in endometrial cancer cell lines (Ishikawa, Hec1B cells) and epithelial cells but not in stromal cells. This finding points to TNF-alpha’s intricate influence on the biology and reproduction of the endometrium. Further in vivo quantitative assessments for endometrial expression of ghrelin peptide, mRNA, and the related molecular aspects for these endometrial effects are needed.
