Abstract

Insights

Researchers identified two diabetic nephropathy (DN) subtypes linked to inflammation and metabolism. They also found 65 potential drugs targeting key pyroptosis-related genes for DN treatment.

Area of Science:

  • Nephrology
  • Immunology
  • Genetics

Background:

  • Diabetic nephropathy (DN) is a severe complication of diabetes mellitus (DM).
  • Inflammation plays a key role in DN development.
  • Pyroptosis, a form of programmed cell death, is linked to immune inflammation and may offer novel therapeutic targets for DN.

Purpose of the Study:

  • To identify pyroptosis-related genes in DN.
  • To develop a predictive model for DN based on pyroptosis genes.
  • To discover potential therapeutic drugs for DN targeting these genes.

Main Methods:

  • Bioinformatic analysis of Gene Expression Omnibus (GEO) datasets (GSE96804, GSE30528, GSE142025) to identify differentially expressed pyroptosis-related genes.
  • Least Absolute Shrinkage and Selection Operator (LASSO) regression for predictive model construction.
  • Consensus clustering, Gene Set Variation Analysis (GSVA), Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interaction (PPI) network analysis to identify subtypes, pathways, and hub genes.
  • Drug-Gene Interaction Database (DGIdb) for drug screening.

Main Results:

  • Identified 24 differentially expressed pyroptosis-related genes in DN.
  • Developed a 16-gene predictive model using LASSO regression.
  • Classified DN into two subtypes based on gene expression, associated with inflammation, immune response, and cell metabolism.
  • Identified 10 hub genes and predicted 65 potential therapeutic compounds targeting these genes.

Conclusions:

  • Two distinct pyroptosis-related DN subtypes were identified.
  • 65 potential therapeutic agents/compounds targeting key genes were predicted.
  • These findings may offer new therapeutic strategies for diabetic nephropathy.
