- Protein methyltransferases regulate diverse physiological and pathological processes through histone and non-histone substrate methylation. While the role of histone methyltransferases in tumorigenesis is well-established, the contribution of non-histone methyltransferases, particularly Methyltransferase 21A (METTL21A), to hepatocellular carcinoma (HCC) progression remains poorly characterized. Here, we report that METTL21A is significantly upregulated in HCC tissues and associated with poor clinical prognosis. Transcriptional activation by CCCTC-binding factor (CTCF) was identified as a key driver of METTL21A overexpression. Functional studies demonstrated that METTL21A promotes HCC growth and metastasis in both in vitro and in vivo models. Mechanistically, METTL21A mediates methylation of Bcl-2-associated athanogene-3 (BAG3), thereby inhibiting its ubiquitination and subsequent degradation. We further identified Tripartite motif containing 21 (TRIM21) as the E3 ligase responsible for BAG3 ubiquitination and found that METTL21A disrupts the TRIM21-BAG3 interaction. Notably, we discovered that the natural compound sophoricoside (Sop) acts as a METTL21A inhibitor and exhibits potent anti-HCC activity. Our study not only elucidates the oncogenic role and molecular mechanism of METTL21A in HCC progression but also highlights its therapeutic potential as a novel drug target for HCC treatment. - Source: PubMed

Zhang Dan-DanHe Xiao-YuYang LiuWu Bang-ShengFu YanLiu Wei-ShiGuo YuFei Chen-JieKang Ju-JiaoFeng Jian-FengCheng WeiTan LanYu Jin-Tai - Intracranial aneurysms (IAs) represent protrusions in the vascular wall, with their growth and wall thinning influenced by various factors. These processes can culminate in the rupture of the aneurysm, leading to subarachnoid hemorrhage (SAH). Unfortunately, over half of the patients prove unable to withstand SAH, succumbing to adverse outcomes despite intensive therapeutic interventions, even in premier medical facilities. This study seeks to discern the pivotal microRNAs (miRNAs) and genes associated with the formation and progression of IAs. - Source: PubMed

Xu DongxiaoGareev IlgizBeylerli OzalPavlov ValentinLe HuangShi Huaizhang - Currently, 80%-90% of liver cancers are hepatocellular carcinomas (HCC). HCC patients develop insidiously and have an inferior prognosis. The methyltransferase-like (METTL) family principal members are strongly associated with epigenetic and tumor progression. The present study mainly analyzed the value of METTLs (METTL1/13/18/21A/23/25/2A/2B/5/6/9) and associated mRNA risk signature for HCC. METTLs expression is upregulated in HCC and is a poor prognostic factor in HCC. METTLs were upregulated in patients older than 60 and associated with grade. Except for METTL25, the remaining 10 genes were associated with the HCC stage, invasion depth (). In addition, METTLs showed an overall alteration rate of 50%. Except for METTL13/2A/25/9, the expression of the other seven genes was significantly associated with overall survival, disease-specific survival, and progression-free survival. Multivariate studies have shown that METTL21A/6 can be an independent prognostic marker in HCC. A total of 664 mRNAs were selected based on Pearson correlation coefficient ( > 0.5), unsupervised consensus clustering, weighted coexpression network analysis, and univariate Cox analysis. These mRNAs were significantly associated with METTLs and were poor prognostic factors in HCC patients. The least absolute shrinkage and selection operator (lasso) was used to construct the best METTLs associated with mRNA risk signature. The mRNA risk signature was significantly associated with age, stage, and grade. The mRNA high-risk group had higher TP53 and RB1 mutations. This study constructed a nomogram with the mRNA risk profile and clinicopathological features, which could better predict the OS of individuals with HCC. We also analyzed associations between METTLs and mRNA risk signatures in epithelial-mesenchymal transition, immune checkpoints, immune cell infiltration, tumor mutational burden, microsatellite instability, cancer stem cells, tumor pathways, and drug sensitivity. In addition, this study constructed a protein interaction network network including METTLs and mRNA risk signature genes related to tumor microenvironment remodeling based on single-cell sequencing. In conclusion, this study provides a theoretical basis for the mechanism, biomarker screening, and treatment of HCC. - Source: PubMed

Wang HaoyuHu ShangshangNie JunjieQin XiaodanZhang XuWang QianLi John Zhong - Protein methyltransferases play various physiological and pathological roles through methylating histone and non-histone targets. Many histone methyltransferases have been reported to regulate the development of spermatogenic cells. However, the specific function of non-histone methyltransferases during spermatogenesis remains unclear. In this study, we found that METTL21A, a non-histone methyltransferase, is highly expressed in mouse testes. In order to elucidate the role of METTL21A in spermatogenesis, we generated a Mettl21a global knockout mouse model using CRISPR/Cas9 technology. Unexpectedly, our results showed that knockout males are fertile without apparent defects in the processes of male germ cell development, including spermatogonial differentiation, meiosis, and sperm maturation. Furthermore, the ablation of METTL21A does not affect the expression and localization of its known targeting proteins in testes. Together, our data demonstrated that METTL21A is not essential for mouse spermatogenesis and male fertility. - Source: PubMed
