To determine whether there was any association between expression of TP53 variants, immune cell infiltration and cancer aggressiveness, unsupervised rank ordered hierarchical clustering of FLTP53, Δ40TP53, Δ133TP53, TP53α, TP53β mRNA levels, immune cell content, the proliferation marker Ki67, and the Gleason score (GS) was performed. The gene discussed is MKI67; the disease is cancer.
