Uterine endometrial cancer (UEC) is an estrogen-related tumor. Succinate and heme metabolism play important roles in the progression of multiple tumors. However, relationship between estrogen, succinate, related regulatory mechanisms remain largely unknown. In this study, we observed that expression aminolevulinate delta synthase 1 (ALAS1) solute carrier family member 38 (SLC25A38) UEC tissues ...
