Conjoint Analysis of Methylation, Transcriptomic, and Proteomic Profiles in Pemphigus Vulgaris

This study explores the molecular mechanisms of pemphigus vulgaris by examining DNA methylation, RNA expression, and protein profiles in 4 patients and 4 healthy controls. Significant DNA methylation changes were found in specific genomic regions, and 1,122 genes showed notable expression differences. Proteomic analysis identified 219 differentially expressed proteins, including FGA, VWF, and ACTG1, which are linked to platelet activation, suggesting its role in the disease's pathogenesis. The study emphasizes the impact of DNA methylation on gene expression related to cell adhesion and immune signaling. Despite these insights, the small sample size limits the conclusions, indicating a need for further research.
