For example, ccRCC patients with low levels of PTENP1 show a shorter OS rate than do those with high PTENP1 levels 107; overexpression of OCT4-pg1 in GC due to aberrant amplification can result in a poor rate of life expectancy in GC patients 105. The gene discussed is PTENP1; the disease is nonpapillary renal cell carcinoma.
