As expected from previous findings on SLCO expression in various ovarian cancer subtypes (Svoboda et al., 2011), SLCO2A1, SLCO2B1, SLCO3A1, and SLCO4A1 were detected in all samples, while expression of the other 8 SLCOs was undetectable (requiring >35 cycles in the real-time RT-PCR) in a varying number of samples within the collective. The gene discussed is SLCO2B1; the disease is ovarian cancer.
