Sex-Specific Gene Regulation in the Development of Atherosclerotic Plaques

This study focuses on identifying sex-specific differences in gene regulation during the development of atherosclerotic plaques. Although atherosclerosis has long been considered a uniform disease, recent insights show that the underlying molecular mechanisms may differ substantially between women and men.

Using transcriptional analysis and advanced bioinformatics, we investigated gene expression profiles in atherosclerotic vascular tissue. Our results demonstrate that women exhibit a unique pattern of gene regulation, particularly in pathways involved in inflammatory processes, extracellular matrix formation, and endothelial activation, which differ significantly from those observed in men. This sex-specific regulation appears to be associated with the development of more fibrotic and erosion-prone plaques in women.

In addition, we identified several candidate genes that may play either protective or risk-modifying roles in the development of symptomatic plaques. These genes represent potential targets for future, more personalized treatment strategies.

Our findings contribute to a better understanding of the molecular basis of sex differences in coronary artery disease and emphasize the importance of incorporating sex as a biological variable in cardiovascular research. Further studies are needed to translate these insights into clinical applications and improved care for female patients.
