G9a regulated the expression of proliferation and apoptosis-related genes in UBC. a, b T24 cells were treated with G9a siRNA, and then, gene expression profiling was performed. Differentially expressed genes are shown in a heatmap (a). GSEA presented the hallmarks of apoptosis (b). c T24 cells were treated with G9a siRNAs. The expression levels of G9a, Cyclin D1, ENO2, Ampkα2, ELL2, and Bim were determined with qRT-PCR. *P < 0.05; **P < 0.01; ***P < 0.001
