	1	An extract of Hypericum perforatum induces wound healing through inhibitions of Ca^(2+) mobilizations,mitochondrial oxidative stress and cell death in epithelial cells:Involvement of TRPM2 channels显示文摘The wound is induced by several mechanical and metabolic factors.In the etiology of the wound recovery,excessive oxidative stress,calcium ion(Ca^(2+))influx,and apoptosis have important roles.Ca^(2+)-permeable TRPM2 channel is activated by oxidative stress.Protective roles of Hypericum perforatum extract(HP)on the mechanical nerve injury-induced apoptosis and oxidative toxicity through regulation of TRPM2 in the experimental animals were recently reported.The potential protective roles in HP treatment were evaluated on the TRPM2-mediated cellular oxidative toxicity in the renal epithelium(MPK)cells.The cells were divided into three groups as control,wound,and wound+HP treatment(75μM for 72 h).Wound diameters were more importantly decreased in the wound+HP group than in the wound group.In addition,the results of laser confocal microscopy analyses indicated protective roles of HP and TRPM2 antagonists(N-(p-Amylcinnamoyl)anthranilic acid and 2-aminoethyl diphenylborinate)against the wound-induced increase of Ca^(2+) influx and mitochondrial ROS production.The wound-induced increase of early(annexin V-FITC)apoptosis and late(propidium iodide)apoptosis were also decreased in the cells by the HP treatment.In conclusion,HP treatment acted protective effects against wound-mediated oxidative cell toxicity and apoptosis through TRPM2 inhibition.These effects may be attributed to their potent antioxidant effect.
