摘要自噬是一个多步骤的细胞过程,它将细胞质中的成分隔离,以便溶酶体降解。BECN 1/Beclin 1是一种中心蛋白,其组装用于形成BECN 1-PIK 3C 3-PIK 3R 4复合物以触发自噬蛋白级联的辅因子。发现BECN 1的调节因子对于理解自噬诱导机制具有重要意义。在这里,我们证明了TRIM 59(一种三方基序蛋白)在非小细胞肺癌(NSCLC)的自噬调节中发挥着重要作用。一方面,TRIM 59通过负性调节NF κ B通路来调节BECN 1的转录。另一方面,TRIM 59调节TRAF 6诱导的K63连接的BECN 1泛素化,从而影响BECN 1-PIK 3C 3复合物的形成。我们进一步证明TRIM 59可以介导K48连接的TRAF 6遍在化并促进TRAF 6的蛋白酶体降解。总之,我们的研究结果揭示了TRIM 59通过影响BECN 1的转录和泛素化在自噬调控中的双重作用。缩略语:会计师事务所:肌动蛋白β; BECN 1:1; CHX:环己酰亚胺; CQ:氯喹;绿色荧光蛋白:绿色荧光蛋白;医管局:血凝素标签;孙鹏:聚组氨酸标签; LC3B:微管相关蛋白1轻链3 β; NF κ B:核因子κ B; NF κ BIA:NF κ B抑制剂α; NSCLC:非小细胞肺癌; PIK 3C 3:磷脂酰肌醇3-激酶催化亚基3型; RELA:RELA原癌基因,NF-κ B亚基; SQSTM 1:多价螯合体1; tGFP:Turbo绿色荧光蛋白; TRAF 6:TNF受体相关因子6; TRIM 59:包含59的三部分基序; B:泛素
ABSTRACT Macroautophagy/autophagy is a multistep cellular process that sequesters cytoplasmic components for lysosomal degradation. BECN1/Beclin1 is a central protein that assembles cofactors for the formation of a BECN1-PIK3C3-PIK3R4 complex to trigger the autophagy protein cascade. Discovering the regulators of BECN1 is important for understanding the mechanism of autophagy induction. Here, we demonstrate that TRIM59, a tripartite motif protein, plays an important role in autophagy regulation in non-small cell lung cancer (NSCLC). On the one hand, TRIM59 regulates the transcription of BECN1 through negatively modulating the NFKB pathway. On the other hand, TRIM59 regulates TRAF6 induced K63-linked ubiquitination of BECN1, thus affecting the formation of the BECN1-PIK3C3 complex. We further demonstrate that TRIM59 can mediate K48-linked ubiquitination of TRAF6 and promote the proteasomal degradation of TRAF6. Taken together, our findings reveal novel dual roles for TRIM59 in autophagy regulation by affecting both the transcription and the ubiquitination of BECN1.
