High expression of USP22 is linked to a poor immunosuppressive microenvironment, and the CpG-aggregated methylation analysis shows that the gene is significantly hypomethylated in tumor samples, which is highly associated with its known upregulation in cancer.<h4>Conclusion</h4>USP22 may have potential relevance in cancer, and the pathways associated with it could offer possible targets for therapeutic intervention. The gene discussed is USP22; the disease is cancer.
