SPEF1 and bladder transitional cell carcinoma: Multiple comparisons revealed that the expression of SPEF1 across molecular subtypes of BLCA had statistically significant differences (data not shown): normal versus neuronal (p=0.0157), normal versus basal squamous (p=1.87 × 10−7), normal versus luminal (p=0.046), normal versus luminal infiltrated (p=4.188 × 10−5), normal versus luminal papillary (p=2.962 × 10−7).
