The transcriptional expression of hsp-65 and hsp-70 in the livers of zinc (Zn)-deficient pregnant rats and their fetuses was examined. Despite the induction of severe fetal pathologies, there were no significant differences in either maternal or fetal hsp-65 or hsp-70 expression between Zn-adequate and Zn-deficient groups, although hsp-65 and hsp-70 expression varied in both groups with time of gestation. Thus, while hsp-70 mRNA content is modulated during differentiation and development, the expression of hsp-65 and hsp-70 is not influenced by Zn deprivation, even when it is extensive enough to induce fetal pathology.
