The Cancer Genome Atlas (TCGA) dataset of 406bladder tumor samples revealed an average FPKM value of 3.3 forSTX1A expression and 14.9 for VAMP2 expression(https://cancergenome.nih.gov). The Human ProteinAtlas (HPA) and Genotype-TissueExpression Dataset (GTEx) demonstrate a similar trend of expression for both genesin bladder cancer. Our data suggests that the expression of STX1Aand VAMP2 was higher in high grade tumors exhibiting aggressivebehavior. Here, VAMP2 is linked to urinary bladder carcinoma.
