In the present work we reported a semiquantitative detection of messenger ribonucleic acids (mRNAs) encoding the human heat shock proteins Hsp70-1, the stress inducible member of the HSP70 family, and hsp90α, the inducible member of the HSP90 family. We investigated the change in the expression of these mRNAs in tissue samples taken from the right atrium of 48 pediatric patients, soon after the ischemic period during surgery to correct congenital heart diseases, in which a crystalloid cold cardioplegic solution was used. No significant variations were found for either hsp70-1 or hsp90α expressions. Moreover, we searched for an association between the hsp70-1 promoter region polymorphism and the expression of the hsp70-1 in a smaller group of these patients (n = 27). The −110AA genotype was on average significantly associated with a decrease in the hsp70-1 mRNA level (P < 0.05), whereas the other genotypes −110AC or −110CC did not seem to be associated with the hsp70-1 expression level. The lack of any observed increase in the hsp70-1 expression level may be due to the high basal level of the Hsp70 protein in the tissues examined.
