Indeed, single-cell analysis revealed that the mean average intensity of OATP1A2 (18-fold, P < .0001), OATP2B1 (3-fold, P = .0002), OATP1C1 (8-fold, P < .0001) and OATP4A1 (5-fold, P = .0001) in GBM IBA1+ cells was significantly higher than in non-tumor IBA1+ cells (Figure 3I–L). The gene discussed is SLCO1A2; the disease is glioblastoma.
