PDCD2L and cancer: To explore the relationship between PDCD2L expression and prognosis of patients in pan-cancer, we performed survival analysis by GEPIA2.The results suggested that high PDCD2L expression indicated poor overall survival rate in ACC (P = 0.04), KICH (P = 0.0075), LAML (P = 0.0032), LGG (P = 0.013), LIHC (P = 0.044), MESO (P = 0.0077), and UVM(P = 0.016),while highPDCD2L expression revealed favorable overall survival rate in UCEC(P = 0.039) (Fig. 2A and B).
