Abstract
This study investigated the effects of hydroxycitric acid tripotassium hydrate on right ventricular function, myocardial and pulmonary vascular remodeling in rats with pulmonary hypertension, and possible mechanisms. METHODS Pulmonary hypertension was induced in male Sprague-Dawley rats by a single subcutaneous injection of monocrotaline or hypoxic chamber. In vivo, inflammatory cytokine (including TNF-α, IL-1β, IL-6, and TGF-β, the level of SOD) expression, superoxide dismutase and hydrogen peroxide levels, and p-IκBα and p65 expressions were detected. In vitro, pulmonary artery smooth muscle cell proliferation and migration, ROS production, and hypoxia-inducible factor-1 expression were also studied. RESULTS Hydroxycitric acid tripotassium hydrate decreased right ventricular systolic pressure and reduced right ventricular fibrosis and pulmonary vascular remodeling in rats with two kinds of pulmonary hypertension. Moreover, the expression of both inflammatory and oxidative stress factors was effectively reduced, and the p65 signaling pathway was found to be inhibited in this study. Additionally, hydroxycitric acid tripotassium hydrate inhibited human pulmonary artery smooth cell proliferation and migration in vitro. CONCLUSIONS This study shows that hydroxycitric acid tripotassium hydrate can alleviate pulmonary hypertension caused by hypoxia and monocycloline in rats, improve remodeling of the right ventricle and pulmonary artery, and inhibit pulmonary artery smooth muscle cell proliferation and migration. The protective effects may be achieved by regulating inflammation and oxidative stress through the p65 signaling pathway.

Biomedicines 2022; 10:biomedicines10061415.

Abstract
Pulmonary arterial hypertension (PAH) is a rare yet serious progressive disorder that is currently incurable. This female-predominant disease unfolds as a pan-vasculopathy that affects all layers of the vessel wall. Five classes of pharmacological agents currently exist to target the three major cellular signaling pathways identified in PAH but are incapable of effectively reversing the disease progression. While several targets have been identified for therapy, none of the current PAH specific therapies are curative and cost-effective as they fail to reverse vascular remodeling and do not address the cancer-like features of PAH. Our purpose is to review the current literature on the therapeutic management of PAH, as well as the molecular targets under consideration for therapy so as to shed light on the potential role and future promise of novel strategies in treating this high-mortality disease. This review study summarizes and discusses the potential therapeutic targets to be employed against PAH. In addition to the three major conventional pathways already used in PAH therapy, targeting PDGF/PDGFR signaling, regulators in glycolytic metabolism, PI3K/AKT pathways, mitochondrial heat shock protein 90 (HSP90), high-mobility group box-1 (HMGB1), and bromodomain and extra-terminal (BET) proteins by using their specific inhibitors, or a pharmacological induction of the p53 expression, could be attractive strategies for treating PAH.

Abstract
As a chronic and progressive disorder, hypertension remains to be a serious public health problem around the world. Among the different types of hypertension, pulmonary arterial hypertension (PAH) is a devastating disease associated with pulmonary arteriole remodeling, right ventricular failure and death. The contemporary management of systemic hypertension and PAH has substantially grown since more therapeutic targets and/or agents have been developed. Evolving treatment strategies targeting the vascular remodeling lead to improving outcomes in patients with hypertension, nevertheless, significant advancement opportunities for developing better antihypertensive drugs remain. Carbon monoxide (CO), an active endogenous gasotransmitter along with hydrogen sulfide (H2S) and nitric oxide (NO), is primarily generated by heme oxygenase (HO). Cumulative evidence suggests that CO is considered as an important signaling molecule under both physiological and pathological conditions. Studies have shown that CO confers a number of biological and pharmacological properties, especially its involvement in the pathological process and treatment of hypertension-related vascular remodeling. This review will critically outline the roles of CO in hypertension-associated vascular remodeling and discuss the underlying mechanisms for the protective effects of CO against hypertension and vascular remodeling. In addition, we will propose the challenges and perspectives of CO in hypertensive vascular remodeling. It is expected that a comprehensive understanding of CO in the vasculature might be essential to translate CO to be a novel pharmacological agent for hypertension-induced vascular remodeling.
