The pharmacological effects of Berberine and its therapeutic potential in different diseases: Role of the phosphatidylinositol 3‐kinase/AKT signaling pathway

Abstract The phosphatidylinositol 3‐kinase (PI3K)/AKT signaling pathway plays a central role in cell growth and survival and is disturbed in various pathologies. The PI3K is a kinase that generates phosphatidylinositol‐3,4,5‐trisphosphate (PI (3–5) P3), as a second messenger responsible for the translocation of AKT to the plasma membrane and its activation. However, due to the crucial role of the PI3K/AKT pathway in regulation of cell survival processes, it has been introduced as a main therapeutic target for natural compounds during the progression of different pathologies. Berberine, a plant‐derived isoquinone alkaloid, is known because of its anti‐inflammatory, antioxidant, antidiabetic, and antitumor properties. The effect of this natural compound on cell survival processes has been shown to be mediated by modulation of the intracellular pathways. However, the effects of this natural compound on the PI3K/AKT pathway in various pathologies have not been reviewed so far. Therefore, this paper aims to review the PI3K/AKT‐mediated effects of Berberine in different types of cancer, diabetes, cardiovascular, and central nervous system diseases.
