Expression of brain natriuretic peptide (BNP) correlates with plasma estradiol levels in the ovariectomized rats fed a high-fat diet (the OF group), and with transforming growth factor (TGF)-β levels. Plasma levels of brain natriuretic peptide (BNP), which is also known as B-type natriuretic peptide, estradiol and TGF-β represented in A, B and D, respectively were measured by the enzyme-linked immunosorbent assay (ELISA) using plasma samples (n=12 for each group) from sham-operated rats fed control diet (SC); ovariectomized rats fed control diet (OC); sham-operated rats fed a high-fat diet (SF); and ovariectomized rats fed a high-fat diet (OF). C represents the correlation between BNP and estradiol in ovariectomized rats (n=12) fed a control diet (OC) or a high-fat diet (OF) for six months. The results were analyzed by two-way ANOVA followed by Bonferroni’s test, and correlations were analyzed by Pearson’s coefficient. # p<0.05 vs. SC, OC and SF; Ω p<0.05 vs. SC and SF.
