CYFIP2 and neoplasm: As shown in Fig. 3A, the expression levels of CYFIP2 in the tumor tissues of BLCA (P < 0.001), ESCA (P < 0.001), KICH (P < 0.001), KIRC (P < 0.001), KIRP (P < 0.001), LUAD (P < 0.01), LUSC (P < 0.001), and UCEC (P < 0.05) were significantly lower than the corresponding control tissues.
