Hypothesis-generating for TGF-β1-driven natriuretic receptor loss in hypertension; requires validation in human models.
TGF-beta 1 downregulates natriuretic peptide receptor expression in aortic smooth muscle cells, particularly in hypertensive models, which may impact vascular remodeling.
Fujio et al. (1994) studied Aortic smooth muscle cell proliferation. Transforming growth factor-beta 1 (TGF-beta 1) was evaluated on Regulation of NPR-A and NPR-B mRNA levels and cyclic GMP production. Transforming growth factor-beta 1 decreased both NPR-A and NPR-B mRNA levels in cultured aortic smooth muscle cells, with a predominant effect in spontaneously hypertensive rat cells at high density.
