The cholesterol efflux transporter, ABCA1, was among the genes with the highest induction in glioma cells plated at high density, with an average rank = #9, (TS543: 1.7x induction, p = 0.001, rank = #96; TS576: 2.2x induction, p = 0.00001, rank = #22; TS600: 4.6x induction, p = 0.00005, rank = #10; TS616: 2.8x induction, p = 0.00005, rank = #8; Fig. 1B,C). The gene discussed is ABCA1; the disease is glioma.
