To reconfirm, 2-BromoPalmitate (2-BP, a general inhibitor of protein palmitoylation) (3) was incubated with human astroglioma cell line U251, it was found that 2-BP can inhibit the level of palmitoylated GFAP (palm-GFAP) gradually in a manner of incubation time (Fig. 1B). The gene discussed is GFAP; the disease is astrocytic tumor.
