Our investigation demonstratedthat high PCNA gene expression exhibited a correlation with poor OSin Adrenocortical carcinoma (ACC) (HR = 3.7, p = 0.002), kidney renal papillary cell carcinoma(KIRP) (HR = 2.2, p = 0.014), brain lower grade glioma (LGG) (HR = 2.6, p = 1.4 × 10–6), lung adenocarcinoma(LUAD) (HR = 1.6, p = 0.0042), mesothelioma (MESO) (HR = 2.4, p = 0.00047), sarcoma (SARC) (HR = 1.7, p = 0.0092), and uveal melanoma (UVM) (HR = 3, p = 0.031) (Figure a). Here, PCNA is linked to uveal melanoma.
