MicroRNAs are involved in end-organ damage during hypertension

Area of Science:

• Cardiovascular Research
• Molecular Biology
• Nephrology

Background:

• Arterial hypertension is a global health concern with significant morbidity and mortality.
• Effective management requires blood pressure control and prevention of end-organ damage.
• MicroRNAs (miRs) are implicated in hypertension-related pathologies affecting organs like the heart, kidneys, and eyes.

Purpose of the Study:

• To review the role of microRNAs (miRs) in target organ damage associated with arterial hypertension.
• To highlight common miR signatures across different end organs, supporting hypertension as a systemic disease.
• To identify miRs as potential therapeutic targets for cardiovascular diseases.

Main Methods:

• Literature review focusing on microRNAs (miRs) and end-organ damage in hypertension.
• Analysis of studies investigating miR involvement in cardiac hypertrophy, fibrosis, heart failure, renal fibrosis, kidney failure, eye disease, and stroke.
• Synthesis of evidence to demonstrate common miR signatures in distinct end organs.

Main Results:

• MicroRNAs (miRs) play a significant role in pathological remodeling processes in various organs affected by hypertension.
• Evidence suggests common microRNA (miR) signatures across different end organs, indicating hypertension's systemic nature.
• Specific miRs acting on common pathways in multiple organs present promising therapeutic targets.

Conclusions:

• Arterial hypertension is a systemic disease with microRNA (miR) involvement in target organ damage.
• MicroRNAs (miRs) represent potential therapeutic targets for managing hypertension-induced end-organ damage.
• Further research into miRs could lead to novel therapeutic strategies in cardiovascular medicine.
