Background: Members of the eukaryotic Hsp90 family function as important molecular chaperones in the assembly, folding and activation of cellular signaling in development. Two hsp90 genes, hsp90 alpha and hsp90 beta, have been identified in fish and homeothermic vertebrates but not in poikilothermic vertebrates. In the present study, the expression of hsp90 alpha and hsp90 beta genes in Xenopus...

Aim: The aim of this study was to investigate heat shock protein 90 (HSP90) and topoisomerase I (Topo I) expression the association between both proteins clinicopathological parameters colorectal cancer (CRC), in order describe their role tumor biology regarding Kirsten Ras (KRAS) – positive/negative cases. Materials Methods: Expression HSP90 Topo I, KRAS gene mutations were estimated primary C...

Functional changes in chaperone systems play a major role the decline of cognition and contribute to neurological pathologies, such as Alzheimer’s disease (AD). While may occur naturally with age or stress trauma, mechanisms involved have remained elusive. The current models suggest that amyloid-β (Aβ) plaque formation leads hyperphosphorylation tau by Hsp90-dependent process triggers neurofibr...

Heat shock protein 90 (Hsp90), a molecular chaperone, is ubiquitous and involved in numerous cellular processes. To contribute to the relatively small collection of vertebrate Hsp90 sequences in the gene data bank, we cloned and sequenced horse (Equus caballus) Hsp90 alpha and beta cDNAs. This enabled identification of horse-specific primers for development of a convenient PCR-based method that...

Candida albicans is the most common human fungal pathogen. Recent evidence has revealed the occurrence of apoptosis in C. albicans that is inducible by environmental stresses such as hydrogen peroxide, acetic acid, and amphotericin B. Apoptosis is regulated by the calcineurin-caspase pathway in C. albicans, and calcineurin is under the control of Hsp90 in echinocandin resistance. However, the r...

Background: Members of the eukaryotic Hsp90 family function as important molecular chaperones in the assembly, folding and activation of cellular signaling in development. Two hsp90 genes, hsp90 and hsp90, have been identified in fish and homeothermic vertebrates but not in poikilothermic vertebrates. In the present study, the expression of hsp90 and hsp90 genes in Xenopus laevis, which is ...
