ABSTRACT
We aimed to assess the effect of gamma radiation on the expression of heat shock proteins Hsc70 and Hsp83 in Aedes aegypti. Adult males were irradiated with 50Gy of gamma radiation, and changes in the expression of proteins in SDS-PAGE gel bands corresponding to molecular weights ~60–75kDa and ~80–95kDa were analyzed at two different time points 6 and 12-hour post-irradiation, using a temporal mass spectrometry based semi-quantitative analysis. A 2-3-fold increase was observed in both proteins Hsc70 and Hsp83, at both time points. In addition, the experiment also revealed the overexpression of several other molecules such as Arginine Kinase - known to be upregulated in certain insects during stress, Esterase B1- implicated in insecticide resistance, and also down-regulation of the 26S proteasome non-ATPase regulatory subunit 1 and ubiquitin-activating enzyme E1 - both known to be involved in ubiquitin-mediated protein degradation. The results taken together with existing data on Hsp83 and Hsc70, indicate that these proteins may enhance the survival of Ae. aegypti following gamma radiation and could serve as molecular markers for the detection of radiation-induced stress.
