Abstract

In experiments on isolated neonatal cardiomyocytes and hearts of adult rats we investigated the influence of polyunsaturated fatty acids (PUFA) on expression of two peroxisome proliferator-activated receptor (PPAR) target genes - fatty acid transport protein (FATP) and interleukin-1 receptor antagonist (IL-1ra). We determined that cell membranes of adult rats heart and car-diomyocytes of neonatal rats which were born by females fed with w-3 PUFA for 4 weeks, contain more w-3 PUFA (alpha-linolenic and docosahexaenoic acids) in comparison with the control. It was shown that w-3 PUFA elevated FATP and IL-1ra mRNA expression in 2,25 (P=0,07) and 8,4 (P<0.00001) folds correspondingly in adult rats tissues. In isolated cardiomyo-cytes, the mRNA expression of FATP and IL-1ra were aug-mented 2.5 folds (P=0,22) and 8,1 folds (P<0.00001), accordingly. Our data show that w-3 PUFA stimulate PPAR target genes expression and allow to permit genetic mechanisms in cardio­protective effects of w-3 PUFA.
