Eight correlations between clinical and epidemiological data and protein expression were noteworthy: diabetes mellitus vs. Ig gamma-2 and apolipoprotein-A1 and albumin; congestive heart failure vs. Ig lambda-2; colonization vs. actin; compressive therapy vs. Ig kappa; systemic arterial hypertension vs. alpha-2-macroglobulin and apolipoprotein-A1; area of ulcer vs. apolipoprotein-A1; race vs. heavy chain Ig and Ig γ-1 chain; age and race vs. Ig γ-1 chain.
The reorganization of the actin cytoskeleton has been implicated in chronic hypertension and the subsequent mechano-adaptive rearrangement of vessel wall components.
In the present study, we evaluated the effect of AFNP on angiotensin II (Ang II)-induced actin cytoskeleton reorganization and aorta remodeling, as well as the involvement of RhoA/Rho-associated coiled kinase (ROCK) pathway in protecting against hypertension.
These results suggest that a reactive oxygen species-Rho kinase-actin polymerization signaling pathway mediates this response and may provide a mechanistic basis for the vasoconstrictor component of pulmonary hypertension.
Neointimal cells in pulmonary hypertension include contributions from the endothelial genetic lineage with induced expression of smooth muscle α-actin and smooth muscle myosin heavy chain.
In L-NAME treated rats, relative to Ad.Null or saline administration, Ad.CMV-hAM-4F2 (i) reduced augmented cardiomyocyte membrane protein oxidation and mRNA expression of pro-oxidant (p22phox) and anti-oxidant (SOD-3, GPx) genes; (ii) attenuated increased cardiomyocyte width and mRNA expression of hypertrophic (sk-alpha-actin) and cardio-endocrine (ANP) genes; (iii) did not attenuate hypertension.
Hypertension and kidney dysfunction in sodium transport observed in the Milan hypertensive strain (MHS) of rats are genetically associated with point mutations of adducin, an actin- and spectrin-binding protein of the membrane cytoskeleton.
