Abstract

The present investigation reveals the results of heat and cold shock expression of HSP-70 in different organs of Cirrhinus mrigala (Ham.). Fishes were exposed to heat and cold shock treatments and thermosensitive organs viz. liver, brain, kidney and gills were dissected out and tissues were analyzed for
HSP70 quantification. At acclimatised temperature (260 C) the HSP – 70 level was highest in liver (10.35 ± 0.8704) and lowest in gills (1.96 ± 0.29). The highest HSP-70 levels were obtained in brain and liver, respectively during heat shock treatment at 370 C for 1 hr, 2hrs, 4 hrs, 22 hrs, 27 hrs, 44 hrs and
48 hrs whereas the lowest HSP-70 levels were obtained in kidney and gills, respectively. In cold shock treatment at 170 C for 18 hrs, 27 hrs and 48 hrs the highest HSP-70 levels were obtained in liver and brain, whereas the lowest levels were obtained in gills.
