To find a suitable model for analyzing the function of OR10H1, we investigated the expression of OR10H1 by qRT-PCR in a large panel of bladder cancer cell lines representing different stages and grades of the disease, and in normal control cells, namely, primary cultures of proliferating normal uroepithelial cells (UPs), and two immortalized cell lines derived from these, HBLAK (Hoffmann et al., 2016) and TERT-NHUC (Chapman et al., 2009). The gene discussed is OR10H1; the disease is urinary bladder cancer.
