Implications of fundamental signalling alterations in diabetes mellitus-associated cardiovascular disease

Area of Science:

• Cardiovascular Science
• Endocrinology
• Molecular Biology

Background:

• Diabetes mellitus (DM) is a primary risk factor for cardiovascular disease (CVD).
• CVD is a leading cause of death and disability among individuals with DM.
• DM involves complex molecular alterations affecting cardiovascular health.

Purpose of the Study:

• To review the adverse implications of cardiovascular signalling alterations in DM-associated cardiovascular pathology.
• To highlight the molecular mechanisms linking DM to CVD.

Main Methods:

• Literature review of studies on DM and cardiovascular signalling.
• Analysis of molecular pathways involved in DM-related CVD.
• Synthesis of current knowledge on signalling alterations in diabetic cardiovascular disease.

Main Results:

• DM modulates expression, activation, or release of key signalling molecules including PI3K, PKB, eNOS, EDRF, NADPH oxidase, EDHF, CGRP, adenosine, iNOS, ROCK, PKC-β2, CaMKII, miR-126, and miR-130a.
• These alterations disrupt cardiovascular physiology, leading to pathology.
• Specific signalling pathways implicated include those involving phosphoinositide 3-kinase (PI3K), protein kinase B (PKB), and endothelial nitric oxide synthase (eNOS).

Conclusions:

• Fundamental cardiovascular signalling alterations in DM contribute significantly to cardiovascular disease pathology.
• Understanding these molecular changes is crucial for managing CVD in diabetic patients.
• Further research into these pathways may reveal novel therapeutic targets for diabetic cardiovascular complications.
