Effective targeted therapy by JAK, STAT and MEK inhibitors in primary EITL cells. (a) Stable cell lines were created by overexpressing GNAI2 wild-type and mutants in HuT78 and Jurkat cells. The expression of relevant proteins was assessed by western blot. (b) Representative images of pERK1/2 immunohistochemical staining in GNAI2 wild-type and mutant tumors. Magnification × 400. (c) Representative ex vivo cell viability assay in primary EITL cells treated with PD0325901 and Stattic for 72 h, and Tofacitinib, Trametinib and Gefitinib for 96 h. All results are normalized to the control (dimethyl sulfoxide (DMSO)) and presented as mean±s.d. The experiment was repeated at least two times with each inhibitor. (d) Immunoblots of indicated proteins in primary EITL cells treated with PD0325901, Tofacitinib and Trametinib for two and Stattic for 24 h at indicated concentrations.
