在这项研究中,我们使用人上皮结直肠腺癌Caco?2细胞研究了热休克反应,该细胞已广泛用于体外上皮模型系统来研究肠上皮功能。我们的研究结果表明,热休克蛋白(Hsp)70,一个典型的热诱导型热休克蛋白的表达,诱导时间和温度依赖性,根据热休克转录因子β 1的激活。Hsp110、Hsp40、Hsp27,而不是Hsp90和Hsp60,也以与Hsp70相同的方式被诱导。虽然血红素加氧酶β 1(HO β 1),也被称为Hsp32,被认为在人类中不是热诱导的,但在Caco β 2细胞中观察到HO β 1的显著诱导。
In this study, we investigated the heat shock response using human epithelial colorectal adenocarcinoma Caco�2 cells, which have been widely used for in vitro epithelial model system to study intestinal epithelial function. Our results show that the expression of heat shock protein (Hsp) 70, a typical heat-inducible Hsp, is induced time- and temperature-dependently, according to the activation of heat shock transcription factor�1. Hsp110, Hsp40, Hsp27, but not Hsp90 and Hsp60, are also induced in the same manner as Hsp70. Although heme oxygenase�1 (HO�1), which is also known as Hsp32, is not thought to be heat-inducible in human, significant induction of HO�1 was observed in Caco�2 cells.
