a Differentially expressed genes (|log2Fold change | > 0.3 and FDR < 0.05 were used as thresholds) after cdkn1a knockout (n = 2437 DEGs). b Heatmap of the osteoblast- and osteoclast-associated genes between the cdkn1aCase9/sgRNA and control groups. c The expression changes of representative DEGs after cdkn1a knockout were validated by qRT‒PCR. d Functional enrichment analysis showing significant KEGG pathways among cdkn1a-regulated genes. e Global view of the cdkn1a-mediated molecular network required for osteoporosis. f GSEA showed that osteoclast differentiation was negatively enriched using cdkn1a-regulated genes.
