vinca/glutathione

On account of its extreme intrinsic resistance to apoptosis and of its strong ability to become chemoresistant after a primary response to drugs, malignant melanoma (MM) is still a therapeutic challenge. We previously showed that glutathione S-transferase mu 1 (GSTM1) acts in synergy with multidrug

In the present study aqueous extract of Piper nigrum seeds and Vinca rosea flowers were administered orally to alloxan induced diabetic rats once a day for 4 weeks. These treatments lead to significant lowering of blood sugar level and reduction in serum lipids. The levels of antioxidant enzymes,

The protective role of leaf antioxidant systems in the mechanism of plant acclimation to growth irradiance was studied in Vinca major, Schefflera arboricola, and Mahonia repens, which were grown for several months at 20, 100, and 1200 [mu]mol photons m-2 s-1. As growth irradiance increased, several

A cisplatin-resistant cell line, SBC-3/CDDP, was established from a human small-cell lung cancer cell line, SBC-3. The SBC-3/CDDP cells were 13.1-fold more resistant to cisplatin than the parent SBC-3 cells. We investigated the cellular changes of this cell line with regard to the development of

Vinflunine (VFL) is a novel derivative of vinorelbine (NVB, Navelbine), which has shown markedly superior antitumor activity to NVB, in various experimental animal models. To establish whether this new Vinca alkaloid participates in P-glycoprotein (Pgp)-mediated multidrug resistance (MDR),

Vinca alkaloids are clinically used to inhibit the growth of malignancy by interfering with microtubule polymerization. The purpose of this study was to identify the molecular mechanisms underlying growth inhibition as well as apoptosis in vinca alkaloid-treated lung adenocarcinoma cells. Consistent
