| 产品描述: | HSP(HSP90)活化剂;HSP(HSP90) Activators;;InformationHSF1A HSF1A is a cell-permeable heat shock transcription factor 1 (HSF1) activator. HSF1A protects cells from stress-induced apoptosis , binds TRiC subunits and inhibits TRiC activity without perturbation of ATP hydrolysis. |
| 体内研究: |
HSF1A 可增强 HSF1 活性,稳定 HSF1 表达,并最大程度减轻 Doxorubicin 诱导的心脏损伤。WKY 大鼠分别接受 DOX (累积剂量:30 mg/kgw) 以及 Doxorubicin 与 HSF1A (100 mg/kgw/天) 联合给药。补充 HSF1A 可显著提高心脏功能,使其恢复至对照组水平。在神经退行性疾病模型中,HSF1A 已被证明能够刺激人类 HSF1 核转位,提高蛋白伴侣表达,并改善蛋白质错误折叠和细胞死亡。超声心动图结果显示,HSF1A 还可以缓解 Doxorubicin 诱导的心脏功能衰竭。 |
