the expression of two oncogenes ( conc ) c-myc and c-fos , coding for nuclear proteins which play a regulatory role in growth and differentiation , and of two genes coding for two heat shock proteins ( hsp ) 68 ( molecular weight 68,000 ) and 70 ( molecular weight 70,000 ) , which have a protective function during stress , have been investigated by northern blot analysis of the total rna , extracted from adult rat ventricle and aorta .
