However, few papers have concentrated on the dynamic interaction between autophagy and ferroptosis throughout the progression of diseases.

Autophagy and ferroptosis may be activated at early stages in endometriosis development.

Furthermore, suppression of ferroptosis may cause further progression of endometriotic lesions.

Hepatocyte steatosis was induced by free fatty acid (FFA) after lentiviral transfection into HepG2 cells. The degree of lipid accumulation was assessed using Oil Red O staining and by measuring several biochemical indices.
