HOXB5 and urinary bladder carcinoma: To investigate the affect of SNP 1010A/G on the expression of HOXB5, we examined the mRNA levels of HOXB5 for the 1010A and 1010G alleles in the heterozygous GA genotype bladder cancer tissues (13 cases) and cell lines (5637, RT4 and J82), using the Taqman assay as described above.
