Genes associated with disc degeneration identified using microarray gene expression profiling and bioinformatics analysis
Disc degeneration is strongly associated with back or neck pain, sciatica, and disc herniation or prolapse. It places an enormous economic burden on society and can greatly affect quality of life. Alternative treatment approaches, such as genetic therapies, are urgently needed to slow or reverse the disc degeneration process. We downloaded gene expression data from Gene Expression Omnibus during various stages of disc degeneration and identified differentially expressed genes (DEGs) as well as dysfunctional pathways through comparisons with controls.
