热休克蛋白(HSP)是一类广泛存在所有原核和真核细胞内,具有高度保守性的蛋白家族。当生物细胞受到应激刺激(如热缺血、缺氧、病毒感染、应激等)和其它损伤因素作用发生应激反应时,就会自动启动HSPs合成基因,促使HSPs的合成,以对细胞起一定的保护作用。Ritassa在1962年果蝇的研究中首次发现,短暂的热休克可以诱导唾液腺染色体出现3个膨突,提示这一区带转录加强,他将这
Heat shock proteins (HSPs) are a family of highly conserved proteins found in all prokaryotic and eukaryotic cells. When the biological cells are stress-stimulated by stress (such as warm ischemia, hypoxia, viral infection, stress, etc.) and other damaging factors, they will automatically activate the synthesis of HSPs to promote the synthesis of HSPs Play a protective role. Ritassa’s first study of fruit flies in 1962 found for the first time that transient heat shock induced 3 bulges in the salivary gland chromosomes suggesting a transcriptional enhancement in this zone,
