Abstract

Induction of cell death and inhibition of cell proliferation in cancer have been set as some of the main goals in anti-tumor therapy. Cancer cell resistance leads to less efficient cancer therapy, and consequently, to higher doses of anticancer drugs, which may eventually increase the risk of serious side effects in normal tissues. Apigenin, a nature-derived and herbal agent, which has shown anticancer properties in several types of cancer, can induce cell death directly and/or amplify the induction of cell death through other anti-tumor modalities. Although the main mechanism of apigenin in order to induce cell death is apoptosis, other cell death pathways, such as autophagic cell death, senescence, anoikis, necroptosis, and ferroptosis, have been reported to be induced by apigenin. It seems that apigenin enhances apoptosis by inducing anticancer immunity and tumor suppressor genes, like p53 and PTEN, and also by inhibiting STAT3 and NF-κB signaling pathways. Furthermore, it may induce autophagic cell death and ferroptosis by inducing endogenous ROS generation. Stimulation of ROS production and tumor suppressor genes, as well as downregulation of drug-resistance mediators, may induce other mechanisms of cell death, such as senescence, anoikis, and necroptosis. It seems that the induction of each type of cell death is highly dependent on the type of cancer. These modulatory actions of apigenin have been shown to enhance anticancer effects by other agents, such as ionizing radiation and chemotherapy drugs. This review explains how cancer cell death may be induced by apigenin at the cellular and molecular levels. © 2023 Bentham Science Publishers.
