Mitochondrial Dynamics of Bcl-2 Family Proteins during 17-β-Estradiol-Induced Apoptosis Correlate with the Malignancy of Endometrial Cancer Cells
Excessive fat intake leads to an increase in cholesterol. Overexposure to estrogen derived from cholesterol is known to contribute to the malignancy of endometrial adenocarcinomas. However, it is not well understood the relationship between the exposure to estrogen and the malignancy of endometrial adenocarcinomas. We investigated how estrogen affected the malignancy of endometrial cancer cells, specifically HEC1 cells (a moderately differentiated adenocarcinoma) and HEC50B cells (a poorly differentiated adenocarcinoma). Cell viability was decreased by exogenous 17-β-estradiol (E
