Outline of Final Research Achievements

In recent work, we demonstrated that mice lacking guanylyl cyclase-A (GC-A-KO), a receptor for atrial and brain natriuretic peptides, show severe postpartum cardiac hypertrophy. Interestingly, the postpartum cardiac hypertrophy in GC-A-KO was induced during lactation. The aim was to investigate the mechanisms underlying the lactation-induced cardiac hypertrophy in GC-A-KO. Additionally, we examined the single-nucleotide polymorphisms of natriuretic peptide-related genes in patients with peripatrum cardiomyopathy (PPCM). Plasma aldosterone level was significantly elevated in lactating GC-A-KO. Furthermore, the administration of a specific mineralocorticoid receptor blocker during lactation significantly suppressed the cardiac hypertrophy in GC-A-KO. Therefore, aldosterone would be a cause of lactation-induced cardiac hypertrophy in GC-A-KO. In addition, genotype distribution of natriuretic peptide clearance receptor gene differed markedly between women with PPCM and their controls.
