研究了热诱导蛋白质合成抑制(HIIPS)与热耐受性的关系。热耐受性是指在其他致死的热处理中存活的瞬时能力。轻微的热休克或暴露在亚砷酸钠中会导致HIIPS的耐受性,而暴露在氨基酸类似物氮杂环丁胺中则不会。热或亚砷酸钠暴露后HIIPS的耐受性的发展和衰退与热休克蛋白(HSP)合成速率的增加和减少是平行的,与HSP水平的持续升高和热耐受状态的持续无关。无论诱导方式如何,在氨基酸类似物存在的情况下,HIIPS的难治性与HSP合成的增加无关,这表明需要功能性的HSP来实现这种效果。在表达HSP70水平升高的HA-I细胞的耐热变体中也发现了对HIIPS的耐受性,这意味着该蛋白在这一过程中发挥了作用。我们的观察建立了一种独特的生物效应,与HSP合成升高时期有关,特别是LISP70。
The relationship of heat-induced inhibition of protein synthesis (HIIPS) and thermotolerance, the transient ability to survive otherwise lethal heat treatments, was studied in HA-1 Chinese hamster fibroblasts exposed to various treatments. A mild heatshock or exposure to sodium arsenite induced a refractoriness to HIIPS, while exposure to the amino acid analog of proline, azetidine, did not. The development and decay of refractoriness to HIIPS after exposure to heat or sodium arsenite paralleled in the increase and decrease of the rate of synthesis of the heat-shock proteins (HSP), and was associated with neither the persistence of elevated levels of HSP nor the persistence of the thermotolerant state. Refractoriness to HIIPS was not associated with the elevated synthesis of HSP in the presence of amino acid analogs regardless of the mode of induction, indicating a requirement for functional HSP for the effect. The refractoriness to HIIPS was also found in heat-resistant variants of HA- I cells that express elevated levels of hsp 70, implicating a role for this protein in this process. Our observation establish an unique biological effect associated with the period of elevated synthesis of the HSP, especially the lisp 70.
