英文摘要 | The role that hsp70 plays in influencing thermal tolerance of a whole animal is not clearly understood. We explored this question by examining liver hsp70 response in the tidepool sculpin (Oligocottus maculosus) and fluffy sculpin (O. snyderi), which have distinct distribution patterns in the intertidal zone. The tidepool sculpin is in upper and lower tidepools, while the fluffy sculpin is exclusively in lower tidepools during a low tide. We conducted experiments in order to investigate: (1) habitat water temperatures; (2) upper thermal tolerance limits; (3) the cellular hsp70 response to changes in water temperature in nature; (4) induction temperatures for hepatic hsp70 and hsp70 mRNA; and (5) effects of long-term heat stress on liver hsp70 levels, in these sculpins. Accordingly, we found: (1) the tidepool sculpin was exposed to a wider temperature range in nature; (2) the tidepool sculpin had higher lethal and induction temperatures for hsp70; (3) the liver hsp70 level of the tidepool sculpin was less sensitive to changes in water temperatures; and (4) the tidepool sculpin had higher constitutive hsp70 levels in nature, compared with the fluffy sculpin. From these results, we proposed that the less thermally sensitive tidepool sculpin may enhance its thermal tolerance by having a large pool of cellular hsp70, thus allowing it to inhabit the upper intertidal zone with relatively large and unpredictable fluctuations in environmental variables.
