The impact of IgSF11-PKM2 pathway on gene expression in osteoclasts

Osteoclasts are primary bone resorbing cells. Previously, we described metabolic regulation of osteoclasts through IgSF11-mediated phosphorylation of the glycolytic enzyme PKM2. Here, we report the impact of IgSF11-PKM2-mediated regulation on gene expression in osteoclasts, utilizing RNA sequencing on osteoclasts engineered to express a chimeric protein, lacking IgSF11, and pharmacologically modulating PKM2 activity. Our analysis identified osteoclast-related genes whose expression is altered by the absence of IgSF11 and by changes in PKM2 activity. This study reveals gene expression changes associated with the IgSF11-PKM2 pathway, providing new insight into its role in osteoclasts.
