840-MYC-USP10-SOX4轴调控胸腺细胞发育与白血病发生的机制研究

from 聊聊Sci

本研究揭示了去泛素化酶 USP10 在胸腺细胞发育和 T 细胞急性淋巴细胞白血病 (T-ALL) 中的核心调控机制。研究发现,USP10 的表达受 MYC 信号诱导,通过去除 SOX4 蛋白的泛素化链来维持其稳定性,进而促进早期胸腺细胞的增殖与分化。实验表明,缺失 USP10 会导致小鼠胸腺细胞发育严重受阻,而恢复 SOX4 水平可显著缓解这一缺陷。此外,在 MYC 驱动的白血病模型中,USP10 呈现高表达特征,利用药物抑制 USP10 能有效延缓疾病进展。这些发现确立了 MYC–USP10–SOX4 轴在免疫平衡与恶性转化中的关键作用,并为 T-ALL 提供了新的潜在治疗靶点。References: Zhang M, Wu H, Lin X, et al.
