Oridonin, an active component isolated from Rabdosia rubescences, has been reported to have antitumor effects. In this study, we compared the signal transduction pathways between TNFalpha-and oridonin-induced L929 cell death. Oridonin and TNFalpha initiated apoptotic morphologic changes, but DNA fragmentation was found in TNFalpha-treated L929 cells but not in oridonin-treated ones. The pan-cas...

Abstract Background The purpose of this study was to use the MTT test assess cytotoxic effects different extracts Convolvulus pluricaulis leaves in vitro . leaf ethanolic extract has been demonstrated trigger apoptosis on HepG2 cancer cell lines, implying anti-cancer activity. Methods cells were grown culture DMEM and incubated with concentrations plant extracts. Survival rates quantified by as...

The enormous bioactive components of different species from marine habitats make them attractive candidates for the discovery new therapeutic active substances in several diseases such as cancer. Sea sponge and tunicate materials are ideal sources chemotherapeutics various cancers due to their rich metabolites. fundamental purpose current study is investigate cytotoxic activity methanolic crude...

objective: verotoxin is a member of shiga toxin family. this family contains ab protein toxins with an enzymatic (a) and a binding (b) compartment. cells that have receptor (gb3) are sensitive to cytotoxic effects of toxin. it has been shown that various tumor cells have gb3 receptor and are selectively sensitive to apoptotic effect of verotoxin. studies on tumor cell lines and laboratory anima...

objective: today, special attention is paid to the use of zirconium dioxide nanoparticle (nano-zro2), a neutral bioceramic metal, particularly for drug and gene delivery in medicine. however, there are some reports implying that use of nano-zro2 is associated with cytotoxic effects like inhibiting the cell proliferation, dna damage and apoptosis. in the present study, we examined whether nano-z...

The TPR proteins FKBP52, FKBP51, Cyp40, and PP5 are found in steroid receptor (SR) complexes, but their receptor-specific preferences and roles remain unresolved. We have undertaken a systematic approach to this problem by examining the contribution of all four TPRs to the localization properties of glucocorticoid (GR) and progesterone (PR) receptors. The GR of L929 cells was found in the cytop...
