WebProlonged culture of arrested human cells mimics hallmarks of epigenetic and transcriptional chronological aging of humans, and can be partially rescued by life-extending treatments / Karbacher Lukas WebSeveral different nuclear export inhibitors (NEIs) have been shown to sensitize drug-resistant cancer cells to anti-cancer drugs. These data suggest that interfering with the … Selective inhibitors of nuclear export (SINEs or SINE compounds) are drugs that block exportin 1 (XPO1 or CRM1), a protein involved in transport from the cell nucleus to the cytoplasm. This causes cell cycle arrest and cell death by apoptosis. Thus, SINE compounds are of interest as anticancer drugs; several are in development, and one (selinexor) has been approved for treatment of multiple myeloma as a drug of last resort. force a hyperlink to open in ie

WebThe observed inhibition was linked to a limitation in the availability of oxaloacetate for the phosphoenolpyruvate carboxykinase reaction and to an increased formation of sn-glycerol 3-phosphate. Finally, the rates of hexose 6-phosphate formation in incubations with cytosols from fed rats were only 50% of those observed with cytosols from animals starved for 48 h. NES signals were first discovered in the human immunodeficiency virus type 1 (HIV-1) Rev protein and cAMP-dependent protein kinase inhibitor (PKI). The karyopherin receptor CRM1 has been identified as the export receptor for leucine-rich NESs in several organisms and is an evolutionarily conserved protein. The export mediated by CRM1 can be effectively inhibited by the fungicide leptomycin B (LMB), providing excellent experimental verification of this pathway.
