Insights
G protein-coupled estrogen receptor 1 (GPER1) shows protective effects against cardiovascular and renal diseases, particularly in aging populations. Understanding GPER1 mechanisms may lead to new therapies for cardio-renal health in the elderly.
Area of Science:
- Cardiovascular and Renal Medicine
- Endocrinology
- Aging Research
Background:
- Cardiovascular (CV) and renal diseases are major global health concerns with high mortality rates.
- Despite advanced treatments, these conditions persist, necessitating further research into underlying mechanisms.
- Age and sex significantly influence the prevalence and progression of cardio-renal diseases, suggesting hormonal regulation.
Purpose of the Study:
- To review the current literature on G protein-coupled estrogen receptor 1 (GPER1) and its role in cardio-renal health.
- To explore GPER1's potential as a therapeutic target, especially in the context of aging.
- To elucidate GPER1-mediated signaling pathways relevant to cardio-renal protection.
Main Methods:
- Literature review of experimental animal models and human studies on GPER1.
- Analysis of GPER1 expression in cardiac, vascular, and renal tissues.
- Examination of GPER1 signaling pathways, including interactions with aldosterone and endothelin-1.
Main Results:
- GPER1 is expressed in key cardio-renal tissues and demonstrates protective effects in animal models.
- GPER1 signaling involves modulation of nitric oxide release, oxidative stress, inflammation, and immune cell infiltration.
- Evidence suggests GPER1 plays a role in mitigating age-related decline in cardio-renal function.
Conclusions:
- GPER1 is a promising target for improving cardio-renal health, particularly in aging individuals.
- Further research into GPER1-evoked mechanisms could yield novel therapeutic strategies.
- Targeting GPER1 may offer a new approach to enhance clinical outcomes for elderly patients with cardio-renal conditions.
Abstract:
Cardiovascular (CV) and renal diseases are increasingly prevalent in the United States and globally. CV-related mortality is the leading cause of death in the United States, while renal-related mortality is the 8th. Despite advanced therapeutics, both diseases persist, warranting continued exploration of disease mechanisms to develop novel therapeutics and advance clinical outcomes for cardio-renal health. CV and renal diseases increase with age, and there are sex differences evident in both the prevalence and progression of CV and renal disease. These age and sex differences seen in cardio-renal health implicate sex hormones as potentially important regulators to be studied. One such regulator is G protein-coupled estrogen receptor 1 (GPER1). GPER1 has been implicated in estrogen signaling and is expressed in a variety of tissues including the heart, vasculature, and kidney. GPER1 has been shown to be protective against CV and renal diseases in different experimental animal models. GPER1 actions involve multiple signaling pathways: interaction with aldosterone and endothelin-1 signaling, stimulation of the release of nitric oxide, and reduction in oxidative stress, inflammation, and immune infiltration. This review will discuss the current literature regarding GPER1 and cardio-renal health, particularly in the context of aging. Improving our understanding of GPER1-evoked mechanisms may reveal novel therapeutics aimed at improving cardio-renal health and clinical outcomes in the elderly.
