IL6 and endometrial cancer: The mRNA expressions of adiponectin (ADIPOQ), leptin, IL6 and TNFα and their receptors (ADIPOR1, ADIPOR2, OBR, IL6R, TNFRSF1A, TNFRSF1B) were studied in the endometrial cancer tissue using qRT‐PCR and fold change relative to the calibrator benign endometrial control sample were calculated, as outlined in the materials and methods section.
