- Myocardial ischemia-reperfusion (I/R) injury is a major cause of cardiac dysfunction, but the mechanisms linking metabolic stress to regulated cardiomyocyte death remain incompletely defined. N6-methyladenosine (mA), the most abundant internal modification of eukaryotic mRNA, is installed by the methyltransferase-like 3 (METTL3)-containing writer complex and regulates RNA fate. Here, we investigated whether METTL3-mediated mA modification contributes to PANoptosis-like cardiomyocyte death during I/R injury. In mouse myocardial I/R and oxygen-glucose deprivation/reoxygenation (OGD/R) models, global mA levels and METTL3 expression were markedly increased. Lactate accumulation was associated with p300-dependent H3K18 lactylation (H3K18la) enrichment at the promoter, suggesting a metabolic-epigenetic mechanism for METTL3 transcriptional upregulation. Functionally, METTL3 promoted PANoptosis-related death signaling, strengthened the association of ZBP1 with PANoptosis-related components, and aggravated infarction, adverse remodeling, and cardiac dysfunction, whereas METTL3 deletion or pharmacological inhibition with STM2457 was protective. Mechanistically, METTL3 enhanced mA modification of mRNA, thereby increasing EGR1 expression through YTHDF1-mediated translational regulation and IGF2BP2-mediated mRNA stabilization. EGR1 further activated transcription, and EGR1 restoration partially reversed the protective effects of METTL3 deficiency. These findings identify a lactate-H3K18la-METTL3-EGR1-ZBP1 axis that drives PANoptosis-like cardiomyocyte death and suggest METTL3 inhibition as a potential strategy against I/R-induced cardiac injury. - Source: PubMed

Chen JieTan YanXie WeiShi LeiQuan HuXiao HuaLiu JiaMao XianhaiChen PanLuo Jia - Oral squamous cell carcinoma (OSCC) is a malignant tumor arising from the oral mucosa and is highly prevalent in Southeast Asia and the Pacific region. Recurrence and metastasis significantly contribute to poor clinical outcomes, highlighting the importance of understanding the underlying molecular mechanisms. Circular RNAs (circRNAs), a class of covalently closed non-coding RNAs, have emerged as key regulators of tumor development and progression. However, their roles in OSCC remain largely unexplored. In this study, we identified for the first time that circRHBDD1(4,5) (hsa_circ_0058493, a 656-nt circRNA generated by back-splicing of exons 4 and 5 of the RHBDD1 gene) is markedly upregulated in OSCC and promotes tumor cell proliferation, invasion, and metastasis. Mechanistically, circRHBDD1(4,5) functions as a molecular scaffold that brings IGF2BP2 and DKK1 mRNA into close proximity, thereby facilitating the mA-dependent recognition of DKK1 mRNA by IGF2BP2, which is mediated by WTAP. This interaction enhances DKK1 mRNA stability, leading to increased DKK1 expression and subsequent activation of the PI3K-AKT signaling pathway, thereby driving the malignant progression in OSCC. Collectively, our findings highlight the critical role of the circRHBDD1(4,5)/IGF2BP2/DKK1 axis in OSCC pathogenesis and provide a potential foundation for developing novel targeted therapeutic strategies. - Source: PubMed

Ren DaixiZhang JiarongHuang MaoWu JieYang MeiLiu YixuanXiang PingjuanQu HongkeWang DanGe JunshangYan QijiaShi LeiXiang BoXiong WeiLi GuiyuanFan ChunmeiZeng Zhaoyang - Cerebral ischemia-reperfusion injury (CIRI) is a leading cause of neurological disability with few effective therapeutic strategies, and ferroptosis has been proven to participate in CIRI progression while its upstream regulatory mechanisms remain poorly defined. Herein, we performed transcriptomic analysis on GSE162072 and GSE58720 datasets, and constructed mouse tMCAO/R and neuronal OGD/R models to recapitulate CIRI. Multiple assays including Longa scoring, TTC staining, H&E staining and Evans blue assay were applied to evaluate neurological function, cerebral infarction, histopathology and blood-brain barrier (BBB) integrity. We also quantified ferroptosis-related markers and detected m6A modification, RNA-protein interaction and mRNA stability via commercial kits, dot blot, MeRIP-qPCR, RIP-qPCR and actinomycin D assays. The results revealed that SLC39A14 was markedly upregulated in CIRI, accompanied by neuronal ferroptosis activation. Knockdown of SLC39A14 alleviated iron overload, lipid peroxidation and ferroptotic neuronal death both in vitro and in vivo. Mechanistically, the m6A reader IGF2BP2 was elevated in CIRI, which directly bound SLC39A14 mRNA to improve its stability and sustain its expression. In vivo AAV-mediated SLC39A14 silencing reduced infarct volume, maintained BBB integrity and relieved neurological deficits. Collectively, IGF2BP2 facilitates CIRI development by driving neuronal ferroptosis through m6A-dependent regulation of SLC39A14 mRNA stability, which may serve as a promising therapeutic target for CIRI. - Source: PubMed

Wang HainingHan BaichaoXu ChenZhong DiChen Hongping - Acute myeloid leukemia (AML) progression relies on complex crosstalk with the bone marrow microenvironment, particularly M2 macrophage polarization. Exosomes mediate intercellular communication, while N6-methyladenosine (m6A) modifications drive tumor malignancy. However, the role of exosomal m6A regulators in coordinating AML progression and macrophage polarization remains unclear. - Source: PubMed
