OBJECTIVE: New evidence is presented for differences in lipid metabolism between healthy and cancer cells, which has increased considerably in recent years. Alterations in lipid metabolism affect important processes such as cell growth. proliferation. and differentiation. Therefore, the purpose of this study is to determine the gene expression levels of the enzymes which have a function in lipid metabolisms such as fatty acid synthase (FASN), sterol regulatory element-binding protein (SREBP), phosphatidylinositol 3-kinase (PI3K), mammalian target of rapamycin (mTOR), protein kinase B (Akt). and AMP-activating protein kinase (AMPK) in patients with endometrial cancer.
