Data on apoptosis reported by researchers at University of Salamanca
June 10th, 2008
According to a study from Salamanca, Spain, "Heat shock protein 90 (Hsp90) is a survival signaling chaperone and a cancer chemotherapeutic target. However, we have found that inhibitors of Hsp90 diminished the apoptotic response induced in leukemic cells by the antitumor alkyl-lysophospholipid analog edelfosine, which acts through lipid raft reorganization." "Edelfosine treatment recruited Hsp90, c-Jun N-terminal kinase (JNK) and apoptotic molecules in lipid rafts, but not the JNK regulators apoptosis signal-regulating kinase 1 (ASK1) and Daxx, or the survival signaling molecules extracellular signal-regulated kinase (ERK) and Akt. Following edelfosine treatment, Hsp90...
