Therapeutic Effect of V8 Affecting Mitophagy and Endoplasmic Reticulum Stress in Acute Myeloid Leukemia Mediated by ROS and CHOP Signaling.

Acute myeloid leukemia (AML) is characterized by the malignant proliferation of abnormally or poorly differentiated myeloid cells in the hematopoietic system. However, there is a lack of effective drugs for treating non-M3 AML. V8, a newly synthesized derivative of the natural flavonoid wogonin, which is a potential anticancer drug, has demonstrated significant antitumor activity both in vitro and in vivo.
