Analysis of TCGA BLCA dataset revealed that the expression of IGF2BP2 in BLCA was comparable to that in normal tissues (Additional file 1: Fig. S1A), while IGF2BP1 expression did not exhibit a significant association with the overall survival of BLCA patients (Additional file 1: Fig.S1B). The gene discussed is IGF2BP1; the disease is bladder transitional cell carcinoma.
