1415-ZDHHC13与ABHD17A动态调节GLI1棕榈酰化控制髓母细胞瘤进展

from 聊聊Sci

这项研究揭示了GLI1蛋白的动态S-棕榈酰化修饰在SHH型髓母细胞瘤(MBSHH)发病与进展中的关键机制。研究发现,酰基转移酶 ZDHHC13 通过在 Cys1034 位点对 GLI1 进行棕榈酰化修饰,有效阻断了其泛素化降解途径,从而增强了该致癌蛋白的稳定性并激活 SHH 信号通路。与之相反,去酰化酶 ABHD17A 则负责移除该修饰,促使 GLI1 发生蛋白酶体降解,进而抑制肿瘤生长。动物实验证实,敲除 Zdhhc13 能显著缓解由 SMO 激活引起的肿瘤严重程度并延长存活期,而 Abhd17a 的缺失则会增加肿瘤的发病率。这些发现不仅阐明了蛋白质脂质修饰对神经肿瘤的调控作用,还为 SHH 驱动型恶性肿瘤的临床治疗提供了潜在的新靶点。References:Shen T, Bao H, Wang J, et al.
