CDK1 and chronic cystitis: Some trials have shown that the mouse model induced by lipopolysaccharide (LPS) is reliable as it can also reflect the pathology of chemical‐induced cystitis.10, 11 To confirm whether Cdk1 was the common potential genetic target of chemical cystitis, Western blot analysis analysis, and polymerase chain reaction (PCR) were further performed in three models, including the ketamine‐induced model, CYC‐induced model, and LPS‐induced model.
