To understand the expression of TAGLN in human bladder cells, we compared levels of TAGLN in human normal primary bladder epithelial cells (HBdEC), bladder smooth muscle cells (HBdSMC), bladder stromal fibroblasts (HBdSF), and four lines of cultured bladder carcinoma cells (RT4, HT1376, T24, and TSGH-8301). The gene discussed is TAGLN; the disease is urinary bladder carcinoma.
