Exogenous expression of heat shock protein 90kDa retards the cell cycle and impairs the heat shock response.
The 90-kDa heat shock protein, HSP90, is an abundant molecular chaperone which functions in cellular homeostasis in prokaryotes and eukaryotes. It is well known that HSP90 plays a critical and indispensable role in regulating cell growth through modulations of various signal transduction pathways, but its roles in cell cycle control are not so well known. We transferred human HSP90 (wild-type o...
متن کاملTargeting the heat shock protein 90 dimer with dimeric inhibitors.
The design, synthesis, and biological evaluation of conformationally constrained coumermycin A1 analogues are reported. Compounds were evaluated against both breast cancer (SKBr3 and MCF7) and prostate cancer (PC3 mm2, A549, and HT29) cell lines. Non-noviosylated coumermycin A1 analogues that manifest potent antiproliferative activity resulting from Hsp90 inhibition are provided, wherein replac...
متن کاملHeat shock protein 90 targeting therapy: state of the art and future perspective
Heat shock protein 90 (Hsp90) is an ATP-dependent molecular chaperone that plays a role in stabilizing and activating more than 200 client proteins. It is required for the stability and function of numerous oncogenic signaling proteins that determine the hallmarks of cancer. Since the initial discovery of the first Hsp90 inhibitor in the 1970s, multiple phase II and III clinical trials of sever...
متن کاملGlobal targeting of subcellular heat shock protein-90 networks for therapy of glioblastoma.
Drug discovery for complex and heterogeneous tumors now aims at dismantling global networks of disease maintenance, but the subcellular requirements of this approach are not understood. Here, we simultaneously targeted the multiple subcellular compartments of the molecular chaperone heat shock protein-90 (Hsp90) in a model of glioblastoma, a highly lethal human malignancy in urgent need of fres...
متن کاملPrevention of autosomal dominant retinitis pigmentosa by systemic drug therapy targeting heat shock protein 90 (Hsp90).
Retinitis pigmentosa (RP) is the most prevalent cause of registered visual handicap among working aged populations of developed countries. Up to 40% of autosomal dominant cases of disease are caused by mutations within the rhodopsin, RDS-peripherin and inosine 5'-monophosphate dehydrogenase type 1 (IMPDH1) genes, at least 30 mutations within which give rise to proteins that cause disease pathol...
