Insights
Rho guanine nucleotide exchange factors (Rho GEFs) are crucial in atherosclerosis development. This review explores Rho GEF roles in atheroma, offering insights for future cardiovascular disease research.
Area of Science:
- Cardiovascular Biology
- Molecular Cell Biology
- Biochemistry
Background:
- Atherosclerosis is a major cause of global mortality, contributing to one-third of all deaths worldwide.
- The precise mechanisms underlying atherosclerosis remain incompletely understood.
- The Rho GTPase family, particularly Rho A, is recognized for its significant role in arteriosclerosis development and progression.
Purpose of the Study:
- To review current research on the relationship and interaction between Rho guanine nucleotide exchange factors (Rho GEFs) and atheroma.
- To highlight the involvement of Rho GEFs, which function upstream of Rho GTPases, in the pathological processes of atherosclerosis.
- To provide a reference for future investigations into atherosclerosis mechanisms.
Main Methods:
- Literature review of existing studies on Rho GEFs and atherosclerosis.
- Analysis of experimental findings from *in vivo* and *in vitro* research.
- Synthesis of current knowledge regarding Rho GEF regulation in atheromatous disease.
Main Results:
- Rho GEFs are implicated in the pathological processes of atherosclerosis.
- Preliminary experimental data suggest Rho GEF regulation of atherosclerosis.
- Research specifically on Rho GEFs in atherosclerosis is limited compared to their general functions.
Conclusions:
- Rho GEFs play a role in the development and progression of atherosclerosis.
- Further research is needed to fully elucidate the function of Rho GEFs in atheroma.
- Understanding Rho GEF involvement may offer new therapeutic targets for cardiovascular disease.
Abstract:
Atherosclerosis is a leading cause of cardiovascular disease, and atherosclerotic cardiovascular disease accounts for one-third of global deaths. However, the mechanism of atherosclerosis is not fully understood. It is well-known that the Rho GTPase family, especially Rho A, plays a vital role in the development and progression of arteriosclerosis. Rho guanine nucleotide exchange factors (Rho GEFs), which act upstream of Rho GTPases, are also involved in the atheromatous pathological process. Despite some research on the role of Rho GEFS in the regulation of atherosclerosis, the number of studies is small relative to studies on the essential function of Rho GEFs. Some studies have preliminarily revealed Rho GEF regulation of atherosclerosis by experiments in vivo and in vitro. Herein, we review the advances in research on the relationship and interaction between Rho GEFs and atheroma to provide a potential reference for further study of atherosclerosis.

Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
