ABSTRACT
Abstract Numerous studies have confirmed that abnormal activation of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway is one of the most common induction mechanisms of T-ALL. In recent years, many literature report that multiple abnormally expressed microRNAs (miRNAs) can participate in the development of T-ALL by regulating the PI3K/AKT signaling pathway. For example, overexpression of miR-19 and miR181a can activate the PI3K/AKT signaling pathway, which leads to the development of T-ALL and induction of chemotherapy drug resistance, as well as the low expression of miR-26b and miR-29a. Apart from the inhibitors and traditional Chinese medicines that target the PI3K/AKT signaling pathway, regulation of the expression of the corresponding miRNA may also be a potential treatment protocol for T-ALL. The mechanisms of PI3K/AKT signaling pathway involved in the development of T-ALL, the role of miRNAs in the PI3K/AKT signaling pathway and the targeted therapy based on this signaling pathway are summarized briefly in this review.
