In ccRCC patients, the expression of CBX3 was positively associated with the abundance of neutrophils (ρ = 0.328, p = 5.34−13) and dendritic cells (ρ = 0.112, p = 1.59−2) and negatively associated with B cells (ρ = −0.149, p = 1.37−3), whereas in pRCC patients, its expression was related only to the abundance of neutrophils (ρ = 0.156, p = 1.21−2). The gene discussed is CBX3; the disease is nonpapillary renal cell carcinoma.
