ABSTRACT

Autophagy is a biological process in which cells maintain homeostasis through degradation of cytoplasmic macromolecules and damaged organelles by membrane vesicle structure .Autophagy plays a critical role in maintai-ning survival of intestinal epithelial cells during intestinal mucosal barrier dysfunction .A negative regulator of auto-phagy may lead to intestinal inflammation and tumorigenesis .

ABSTRACT

Matrine is a traditional Chinese medicine extraction which can inhibit the proliferation, migration and apoptosis of tumor cells. Cell signal transduction affects the tumor biological behavior and growth condition. Except for the widely research of MAPK, JAK-STAT, NF-κB signal transduction pathways, the latest signaling pathways about matrine are Wnt/β-catenin signaling pathway and mTOR signaling pathway. These pathways are mainly activated by the phosphorylated key proteins to alleviate inflammatory reaction and inhibit the growth of tumor cells and tumor biological behaviors. The research of matrine by cell signaling pathways can provide molecular targeted therapy with theoretical basis. The relationship among different signaling pathways related to the anti-tumor effect of matrine is worth studying deeply in the future.

ABSTRACT

Multidrug resistance (MDR) limits the clinical application and efficacy of chemotherapy drugs. Thus, MDR is the big-gest obstacle to the success of chemotherapy. Complex and diverse MDR mechanisms exist, including the following:adenosine triphos-phate-binding cassette membrane transport protein family, anti-apoptotic or enhanced DNA repair, mutations in drug targets or metabol-ic enzymes, microRNA, and cancer stem cells. Autophagy can degrade organelles and proteins that have been damaged in the cyto-plasm through the formation of autolysosome and recycle metabolites. Maintaining intracellular homeostasis and a balanced internal en-vironment is highly significant. Recent studies found that autophagy is closely related to the pathophysiology of MDR. The interaction between autophagy and MDR and the possible molecular mechanisms underlying these phenomena are reviewed. This paper elucidates the occurrence of MDR in relation to autophagy in order to provide new information on chemotherapy MDR.
