Genetic deletion of MrgD receptor disrupts cardiac protein homeostasis in mice Beatriz Alexandre-Santos, Luiza Mazzali Ferraz, Ana Beatriz Proença, Nícia Pedreira Soares, Guilherme dos Santos Reis, Maria Eduarda Lima da Silva, D’Angelo Carlo Magliano, Maria Jose Campagnole-Santos, Antonio Claudio Lucas da Nóbrega, Robson Augusto Souza Santos, Eliete Dalla Corte Frantz Molecular Biology Reports, 2026 Cardiovascular diseases are the leading cause of death worldwide. An important mechanism involved is the disruption in protein homeostasis by overactivation of the classical axis of the renin-angiotensin system. The counterregulatory axis counteracts these effects; however, the MrgD receptor has recently been described, and its effects are unknown. Thus, this study aims to evaluate the impact of MrgD deficiency on cardiac protein homeostasis. 16-week-old wild-type (WT) and MrgD knockout (MrgD KO) male C57BL/6J mice were evaluated for systolic blood pressure (SBP), cardiac morphology, MDA levels, carbonyl content, and protein homeostasis markers. SBP and heart mass remained unaltered. MrgD deficiency increased left ventricular mass and led to cardiac atrophy by reduced left ventricular wall thickness and cardiomyocyte cross-sectional area. Collagen (types 1 and 3) deposition and MMP-2 cardiac protein expression were elevated in MrgD KO. Genetic deletion of MrgD increased NOX2, NOX4, and ERO1α cardiac protein expression. MDA levels were similar between groups, and carbonyl content was higher in MrgD KO. GRP78, CHOP, MuRF-1, Atrogin-1, and polyubiquitinated proteins were increased in MrgD KO mice, indicating a loss of protein homeostasis. The genetic deletion of MrgD promoted cardiac remodeling and disrupted protein homeostasis, with increased pro-oxidative response and ER stress. This was associated with protein degradation by the activation of the ubiquitin-proteasome pathway.
Bisphenol S-induced cardiac remodeling is associated with an imbalance in the renin-angiotensin system Guilherme dos Santos Reis, Maria Eduarda Lima da Silva, Luiza Mazzali Ferraz, Cristiane Matsuura, Antonio Claudio Lucas da Nóbrega, Leandro Miranda-Alves, D'Angelo Carlo Magliano, Eliete Dalla Corte Frantz, Beatriz Alexandre-Santos Environmental Research, 2026 Cardiovascular diseases (CVD) are the leading cause of death worldwide, and cardiac remodeling is a key pathological feature. The renin-angiotensin system (RAS) plays a central role in CVD, but whether different doses of bisphenol S (BPS) modulate cardiac RAS remain unclear. Adult male C57BL/6 mice were assigned to control (C) or 4 (B4), 25 (B25), and 50 (B50) μg/kg/day of BPS in drinking water for 12 weeks. Body mass (BM), plasma cholesterol, left ventricle (LV) and cardiomyocyte morphology, RAS components and signaling markers, and remodeling mediators were assessed. B4 and B25 increased BM and plasma cholesterol, with a higher cardiac risk ratio. Regarding the RAS, all BPS doses overactivated the classical axis, evidenced by increased ACE activity and protein expression, and greater AT1R immunostaining, while suppressing the counterregulatory axis, with reduced ACE2 activity and protein expression and lower Mas receptor immunostaining. AT1R-related intracellular signaling (NOX2, NOX4, ERK 1/2 protein expression) increased in all groups. B4 and B25 presented ER stress, with increased GRP78 and CHOP protein expression, and ATF4 protein expression increased in all groups. B4 and B25 promoted pathological cardiac hypertrophy, with increased LV mass, wall thickness, chamber area and ANP protein expression. Inflammation markers protein expression was observed in all groups, particularly B4 and B25. All doses induced a pro-fibrotic profile with increased collagen deposition and TGFβ protein expression, more pronounced in B50. Overall, exposure to different BPS doses shifted the RAS activation towards the classical axis. These findings underscore the need for public policies regulating BPS.
Dysfunctional white adipose tissue in the progression of endometriosis: The role of the renin-angiotensin system Gabriela Rodrigues Medeiros, Flavia Maria Silva-Veiga, Ana Lívia Ladislau de Souza Vieira, Maria Júlia Amancio Lisboa, Roberto de Souza, Eliza Prodel, Eliete Dalla Corte Frantz, Vanessa Souza-Mello Life Sciences, 2026 Obesity is a multifactorial chronic disease with pandemic-level prevalence, characterized by excessive or abnormal fat accumulation, dysregulation of body homeostasis, and chronic low-grade inflammation. This complex comorbidity shares some etiological pathways with other diseases such as endometriosis, an inflammatory and estrogen-dependent disorder that affects 5-10% women of reproductive age. The literature shows an inverse correlation between low body mass index (BMI) and the onset of endometriosis, linking obesity to more severe cases. Both endometriosis and obesity share similar underlying mechanisms, including inflammation and angiogenesis. Fat accumulation leads to overactivation of the classical renin-angiotensin system (RAS) axis, triggering impaired lipolysis and adipogenesis, increased lipogenesis, oxidative stress, inflammation, and insulin resistance in white adipose tissue (WAT). Although studies concerning the RAS activity of WAT in women with endometriosis are limited, the chronic inflammatory environment linked to obesity demands further investigation. This review examines the interconnections among RAS, adipogenesis, and inflammation in women with obesity and endometriosis, as well as their potential clinical implications.
