MOG analysis shows CD70 expression is higher in two types of renal tumors, KIRC and KIRP, and increases with disease progression (Figure 4A), but CD70 levels in another renal tumor type, KICH, have slightly lower expression than in non-tumor samples; thus, specifically in the case of KICH, low CD70 levels might be an unfavorable prognosis. The gene discussed is CD70; the disease is neoplasm.
