Effects of Trandolapril on Structural, Contractile and Electrophysiological Remodeling in Experimental Volume Overload Heart Failure. Front Pharmacol 2021; 12:729568.

Abstract
Chronic volume overload induces multiple cardiac remodeling processes that finally result in eccentric cardiac hypertrophy and heart failure. We have hypothesized that chronic angiotensin-converting enzyme (ACE) inhibition by trandolapril might affect various remodeling processes differentially, thus allowing their dissociation. Cardiac remodeling due to chronic volume overload and the effects of trandolapril were investigated in rats with an aortocaval fistula (ACF rats). The aortocaval shunt was created using a needle technique and progression of cardiac remodeling to heart failure was followed for 24 weeks. In ACF rats, pronounced eccentric cardiac hypertrophy and contractile and proarrhythmic electrical remodeling were associated with increased mortality. Trandolapril substantially reduced the electrical proarrhythmic remodeling and mortality, whereas the effect on cardiac hypertrophy was less pronounced and significant eccentric hypertrophy was preserved. Effective suppression of electrical proarrhythmic remodeling and mortality but not hypertrophy indicates that the beneficial therapeutic effects of ACE inhibitor trandolapril in volume overload heart failure might be dissociated from pure antihypertrophic effects.

Abstract
We studied the effects of the H(2)S donor Na(2)S on the mean arterial blood pressure (MAP) and heart and breathing rates of anesthetized Wistar rats in the presence and absence of captopril. Bolus administration of Na(2)S (1-4 micromol/kg) into the right jugular vein transiently decreased heart and increased breathing rates; at 8-30 micromol/kg, Na(2)S had a biphasic effect, transiently decreasing and increasing MAP, while transiently decreasing heart rate and increasing and decreasing breathing rate. These results may indicate independent mechanisms by which H(2)S influences MAP and heart and breathing rates. The effect of Na(2)S in decreasing MAP was less pronounced in the presence of captopril (2 micromol/l), which may indicate that the renin-angiotensin system is partially involved in the Na(2)S effect. Captopril decreased H(2)S-induced NO release from S-nitrosoglutathione, which may be related to some biological activities of H(2)S. These results contribute to the understanding of the effects of H(2)S on the cardiovascular system.

Calcitonin Gene-Related Peptide Regulates Cardiomyocyte Survival through Regulation of Oxidative Stress by PI3K/Akt and MAPK Signaling Pathways.

Abstract
CGRP and specific CGRP receptors are found in the heart where they produce positive-inotropic and anti-apoptotic effects, key adaptations to exercise and cardiovascular disease. PI3K/Akt and MAPK signaling imbalances are associated with cardiomyocyte pathologies; however, the effects of CGRP on these pathways are unclear. Therefore, we hypothesized that CGRP modulates inotropic and apoptotic adaptations of cardiomyocytes by regulating PI3K/Akt and MAPK/ERK signaling balances. We treated cardiomyocytes with combinations of CGRP, PI3K/Akt and MAPK signaling agonists and antagonists. We evaluated expression of the mRNA and proteins levels of survival signaling molecules related to the PI3K/Akt and MAPK and measured apoptosis by caspase 3/7 activity. CGRP1-37 decreased Akt, NFκB, SOD-3 and increased ERK1/2 and p38 MAPK expressions, which was antagonized by CGRP8-37. Akt-negative construct transfection, Ad.Akt(K179M), inhibited the CGRP1-37-induced increment in MAPK expressions. A PI3K-antagonist treatment with LY294002 or CGRP1-37/Ad.Akt(K179M) co-treatment alleviated the CGRP-increased caspase activity and -decrements in SOD-3. These findings demonstrate a CGRP negative effect on the PI3K/Akt signaling pathway and CGRP receptor-induced crosstalk between PI3K/Akt and MAPK in normal cardiomyocytes. Future studies to differentiate CGRP effects on intracellular signal transduction mechanisms in pathological conditions will elucidate the significance of CGRP in, and provide novel therapeutic targets for, heart failure.

Abstract
During Pregnancy, heart develops physiological left ventricular hypertrophy as a result of the natural volume overload. Previously we have characterized the molecular and functional signature of heart hypertrophy during pregnancy. Cardiac hypertrophy during pregnancy is a complex process that involves many changes including in the signalling pathways, composition of extracellular matrix as well as the levels of sex hormones. This review summarises the recent advances and the new frontiers in the context of heart hypertrophy during pregnancy. In particular we focus on structural and extracellular matrix remodelling as well as signalling pathways in pregnancy-induced physiological heart hypertrophy. Emerging evidence shows that various microRNAs modulate key components of hypertrophy, therefore the role of microRNAs in the regulation of gene expression in pregnancy induced hypertrophy is also discussed. We also review the role of ubiquitin proteasome system, the major machinery for the degradation of damaged and misfolded proteins, in heart hypertrophy. The role of sex hormones in particular estrogen in cardiac remodeling during pregnancy is also discussed. We also review pregnancy-induced cardiovascular complications such as peripartum cardiomyopathy and pre-eclampsia and how the knowledge from the animal studies may help us to develop new therapeutic strategies for better treatment of cardiovascular diseases during pregnancy. Special emphasis has to be given to the guidelines on disease management in pregnancy.
