Reversion of P-Glycoprotein-Mediated Multidrug Resistance in Human Leukemic Cell Line by Diallyl Trisulfide
Multidrug resistance (MDR) is the major obstacle in chemotherapy, which involves multiple signaling pathways. Diallyl trisulfide (DATS) is the main sulfuric compound in garlic. In the present study, we aimed to explore whether DATS could overcome P-glycoprotein-(P-gp-)mediated MDR in K562/A02 cells, and to investigate whether NF-κB suppression is involved in DATS-induced reversal of MDR. MTT as...
متن کاملReversion of P-glycoprotein-mediated multidrug resistance by diallyl trisulfide in a human osteosarcoma cell line.
Diallyl trisulfide (DATS), the main sulfuric compound in garlic, has been shown to have antitumor effects. The present study aimed to ascertain whether DATS reverses the drug resistance of human osteosarcoma cells in vitro and to investigate its potential mechanisms. Human osteosarcoma U2-OS cells were treated with different concentrations of DATS. Cell proliferation was measured by 3-(4,5-dime...
متن کاملDiallyl trisulfide reverses drug resistance and lowers the ratio of CD133+ cells in conjunction with methotrexate in a human osteosarcoma drug-resistant cell subline.
P-glycoprotein (P-gp) overexpression and tumor stem cells are thought to be important factors in the cross-resistance of cancer cells. There have been no studies on whether diallyl trisulfide (DATS) can reverse drug resistance in human osteosarcoma cells. In the present study, we demonstrated that DATS down-regulated P-gp expression and reversed drug resistance. DATS and methotrexate (MTX) decr...
متن کاملAlkenyl group is responsible for the disruption of microtubule network formation in human colon cancer cell line HT-29 cells
Alk(en)yl trisulfides (R-SSS-R') are organosulfur compounds produced by crushed garlic and other Allium vegetables. We found that these compounds exhibit potent anticancer effects through the reaction with microtubules, causing cell cycle arrest. Nine alk(en)yl trisulfides including dimethyl trisulfide, diethyl trisulfide, dipropyl trisulfide (DPTS), dibutyl trisulfide, dipentyl trisulfide, dia...
متن کاملDietary Bioactive Diallyl Trisulfide in Cancer Prevention and Treatment
Bioactive dietary agents have been shown to regulate multiple cancer hallmark pathways. Epidemiologic studies have linked consumption of Allium vegetables, such as garlic and onions, to decreased incidence of cancer. Diallyl trisulfide (DATS), a bioactive compound derived from Allium vegetables, has been investigated as an anti-cancer and chemopreventive agent. Preclinical studies provide ample...
