ELAVL1 and urinary bladder cancer: Many clinical investigations have shown a positive relationship between cytoplasmic HuR accumulation and VEGF-A [136,137], VEGF-C [101,109], COX-2 [103,104,109,138–140], and IL-8 [130] in human tumor samples, whereas cytoplasmic staining of HuR was not associated with VEGF-D expression in bladder cancer [109].
