Sodium butyrate alleviates right ventricular hypertrophy in pulmonary arterial hypertension by inhibiting H19 and affecting the activation of let-7g-5p/IGF1 receptor/ERK. Eur J Pharmacol 2024; 965:176315. [PMID: 38176636 DOI: 10.1016/j.ejphar.2024.176315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 12/23/2023] [Accepted: 01/02/2024] [Indexed: 01/06/2024]
Abstract
Pulmonary arterial hypertension (PAH) is a complex and fatal cardio-pulmonary vascular disease. Decompensated right ventricular hypertrophy (RVH) caused by cardiomyocyte hypertrophy often leads to fatal heart failure, the leading cause of mortality among patients. Sodium butyrate (SB), a compound known to reduce cardiac hypertrophy, was examined for its potential effect and the underlying mechanism of SB on PAH-RVH. The in vivo study showed that SB alleviated RVH and cardiac dysfunction, as well as improved life span and survival rate in MCT-PAH rats. The in vivo and in vitro experiments showed that SB could attenuate cardiomyocyte hypertrophy by reversing the expressions of H19, let-7g-5p, insulin-like growth factor 1 receptor (IGF1 receptor), and pERK. H19 inhibition restored the level of let-7g-5p and prevented the overexpression of IGF1 receptor and pERK in hypertrophic cardiomyocytes. In addition, dual luciferase assay revealed that H19 demonstrated significant binding with let-7g-5p, acting as its endogenous RNA. Briefly, SB attenuated PAH-RVH by inhibiting the H19 overexpression, restoring the level of let-7g-5p, and hindering IGF1 receptor/ERK activation.

Abstract
[Purpose] The purpose of this study was to investigate the effects of glucose intake on physical function in a heart failure rat model. [Materials and Methods] Five-week-old male Wistar rats were used for this study. Monocrotalin (40 mg/kg) was administered intraperitoneally to rats to induce heart failure. The rats were divided into two groups, control and MCT; the MCT group was further classified according to glucose concentration (0%, 10%, and 50%). [Results] Glucose intake during heart failure prevented the loss of body weight, skeletal muscle, and fat mass. Myocardial metabolism in heart failure was enhanced by hypoxia, which in turn, enhanced the glycolytic system. [Conclusion] Glucose loading suppressed cardiac hypertrophy and improved physical function in the heart failure rat model.

Effects of nasal high flow on sympathovagal balance, sleep, and sleep-related breathing in patients with precapillary pulmonary hypertension. Sleep Breath 2021; 25:705-717. [PMID: 32827122 PMCID: PMC8195975 DOI: 10.1007/s11325-020-02159-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Revised: 07/09/2020] [Accepted: 08/01/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND In precapillary pulmonary hypertension (PH), nasal high flow therapy (NHF) may favorably alter sympathovagal balance (SVB) and sleep-related breathing through washout of anatomical dead space and alleviation of obstructive sleep apnea (OSA) due to generation of positive airway pressure. OBJECTIVES To investigate the effects of NHF on SVB, sleep, and OSA in patients with PH, and compare them with those of positive airway pressure therapy (PAP). METHODS Twelve patients with PH (Nice class I or IV) and confirmed OSA underwent full polysomnography, and noninvasive monitoring of SVB parameters (spectral analysis of heart rate, diastolic blood pressure variability). Study nights were randomly split into four 2-h segments with no treatment, PAP, NHF 20 L/min, or NHF 50 L/min. In-depth SVB analysis was conducted on 10-min epochs during daytime and stable N2 sleep at nighttime. RESULTS At daytime and compared with no treatment, NHF20 and NHF50 were associated with a flow-dependent increase in peripheral oxygen saturation but a shift in SVB towards increased sympathetic drive. At nighttime, NHF20 was associated with increased parasympathetic drive and improvements in sleep efficiency, but did not alter OSA severity. NHF50 was poorly tolerated. PAP therapy improved OSA but had heterogenous effects on SVB and neutral effects on sleep outcomes. Hemodynamic effects were neutral for all interventions. CONCLUSIONS In sleeping PH patients with OSA NHF20 but not NHF50 leads to decreased sympathetic drive likely due to washout of anatomical dead space. NHF was not effective in lowering the apnea-hypopnoea index and NHF50 was poorly tolerated.

Abstract
Introduction:
Animal models have been used to understand the pathophysiology of
pulmonary hypertension, to describe the mechanisms of action and to evaluate promising active
ingredients. The monocrotaline-induced pulmonary hypertension model is the most used animal
model. In this model, invasive and non-invasive hemodynamic variables that resemble human
measurements have been used. Aim: To define if non-invasive variables can predict hemodynamic
measures in the monocrotaline-induced pulmonary hypertension model.
Materials and Methods:
Twenty 6-week old male Wistar rats weighing between 250-300g from the
bioterium of the Universidad del Valle (Cali - Colombia) were used in order to establish that the
relationships between invasive and non-invasive variables are sustained in different conditions
(healthy, hypertrophy and treated). The animals were organized into three groups, a control group
who was given 0.9% saline solution subcutaneously (sc), a group with pulmonary hypertension
induced with a single subcutaneous dose of Monocrotaline 30 mg/kg, and a group with pulmonary
hypertension with 30 mg/kg of monocrotaline treated with Sildenafil. Right ventricle ejection
fraction, heart rate, right ventricle systolic pressure and the extent of hypertrophy were measured.
The functional relation between any two variables was evaluated by the Pearson correlation
coefficient.
Results:
It was found that all correlations were statistically significant (p <0.01). The strongest
correlation was the inverse one between the RVEF and the Fulton index (r = -0.82). The Fulton index
also had a strong correlation with the RVSP (r = 0.79). The Pearson correlation coefficient between
the RVEF and the RVSP was -0.81, meaning that the higher the systolic pressure in the right
ventricle, the lower the ejection fraction value. Heart rate was significantly correlated to the other
three variables studied, although with relatively low correlation.
Conclusion:
The correlations obtained in this study indicate that the parameters evaluated in the
research related to experimental pulmonary hypertension correlate adequately and that the
measurements that are currently made are adequate and consistent with each other, that is, they have
good predictive capacity.

Abstract
Pulmonary hypertension (PH) is a pulmonary vascular disease characterized by increased pulmonary artery pressures. Long standing pulmonary arterial pressure overload leads to right ventricular (RV) hypertrophy, RV failure, and death. RV failure is a major determinant of survival in PH. Oxidative stress has been associated with the development of RV failure secondary to PH. Here we summarize the structural and functional changes in the RV in response to sustained pulmonary arterial pressure overload. Furthermore, we review the pre-clinical and clinical studies highlighting the association of oxidative stress with pulmonary vasculature and RV remodeling in chronic PH. Targeting oxidative stress promises to be an effective therapeutic strategy for the treatment of RV failure.
