Objective: SOX11 is expressed in numerous malignancies, including hepatocellular carcinomas(HCC), but its oncogenic function has not been elucidated. Here, we performed a comprehensive bioinformatics analysis of the Liver Hepatocellular Carcinoma(LIHC) dataset to investigate the function of SOX11 in ***: SOX11 expression data from The Cancer Genome Atlas(TCGA) and Gene Expression Omnibus(GEO) were validated by immunohistochemistry(IHC). Co-expression, differential expression, and functional analyses utilized TCGA-LIHC, Timer 2.0, Metascape, GTEx, and Linked Omics databases. Associations with immune infiltration, ferroptosis, and immune checkpoint genes were assessed. Genetic changes were explored via CBio Portal. Logistic regression, receiver operating characteristic curve(ROC), Kaplan-Meier analysis, and nomogram modeling evaluated associations with HCC clinicopathological features. SOX11's impact on proliferation and migration was studied in HepG2 and Hu H7 cell ***: SOX11 was significantly elevated in HCC tumors compared to controls. SOX11-associated genes exhibited differential expression in pathways involving extracellular membrane ion channels. Significant associations were found between SOX11 levels, immune infiltration, ferroptosis, and immune checkpoint genes in HCC ***11 levels correlated with HCC stage, histologic grade, and tumor status, and independently predicted overall and disease-specific survival. SOX11 expression effectively distinguished between tumor and normal liver *** correlations highlighted a significant relationship between SOX11 and ferroptosis-associated *** SOX11 levels in HepG2 and Hu H7 cells resulted in reduced proliferation and ***: SOX11 was found to represent a promising biomarker within HCC diagnosis and prognosis together with being a possible drug-target.

PCAF-mediated acetylation of METTL3 impairs mRNA translation efficiency in response to oxidative stress

引用

Science China Life Sciences 2024年第10期67卷 2157-2168页

METTL3 methylates RNA and regulates the fate of mRNA through its methyltransferase activity. METTL3 enhances RNA translation independently of its catalytic activity. However, the underlying mechanism is still elusive. Here, we report that METTL3 is both interacted with and acetylated at lysine 177 by the acetyltransferase PCAF and deacetylated by SIRT3. Neither the methyltransferase activity nor the stability of METTL3 is affected by its acetylation at K177. Importantly, acetylation of METTL3 blocks its interaction with EIF3H, a subunit of the translation initiation factor, thereby reducing mRNA translation efficiency. Interestingly, acetylation of METTL3 responds to oxidative stress. Mechanistically, oxidative stress enhances the interaction of PCAF with METTL3, increases METTL3 acetylation, and suppresses the interaction of METTL3 with EIF3H, thereby decreasing the translation efficiency of ribosomes and inhibiting cell proliferation. Altogether,we suggest a mechanism by which oxidative stress regulates RNA translation efficiency by the modulation of METTL3 acetylation mediated by PCAF.
