Figure 3: The regulation of HLA increase was at the transcript level.
(A) Representative western blots probing for HLA-A, beta-2-microglobulin (B2M), and GAPDH (loading control) in TPC1 cells at 72hrs after RET inhibitor treatments. (B) HLA and antigen processing machinery (TAP1, TAP2 and Beta-2 microglobulin) transcript levels measured by qPCR at 48hrs after RET inhibitor treatment. (C) Western blots for HLA-A, beta-2-microglobulin (B2M), and GAPDH (loading control) and (D) RNA levels of for HLA-A, beta-2-microglobulin (B2M), and TAP-1 and TAP-2 in Karpas 299 cells and SUDHL-1 cells after ceritinib treatment. qPCR experiments were in performed in technical triplicate.
