Summary: Regional bias of m(6)A mRNA modification avoids the splice site region, and it is uncertain whether the exon-intron boundary could affect m(6)A deposition. Deep learning modeling shows that the exon-intron boundary represses a portion of m(6)A deposition at adjacent exons. Experimental validation confirms that m(6)A signal increases when the host gene does not undergo pre-mRNA splicing. The inhibited m(6)A sites exhibit higher m(6)A enhancers and lower m(6)A silencers locally, contributing to stable mRNAs and flexible protein coding.

Summary: KAR4, a protein in yeast, has a role in both mating and meiosis. Mutations in KAR4 abolish its interaction with the transcription factor Ste12p, resulting in loss of mating function. In meiosis, KAR4 interacts with other proteins and is involved in mRNA methylation. Furthermore, KAR4 plays a critical role in different stages of meiosis and sporulation.

Summary: The study reveals that accumulation of unfolded/misfolded proteins selectively induces N-6-adenosine-methyltransferase-14 (METTL14) expression, which promotes C/EBP-homologous protein (CHOP) mRNA decay to inhibit pro-apoptotic gene expression. The unfolded protein response induces METTL14 expression by competing against the ER-associated degradation machinery, resulting in adaptation to proteotoxic stress.

Summary: The METTL3-/METTL14-containing complex catalyzes N6-methyladenosine (m6A) modification, affecting mRNA stability. The R298P mutation in METTL14 is found in multiple cancer types, but its effects are not fully understood. This study shows that the heterozygous R298P mutation promotes cancer cell proliferation, while the homozygous mutation reduces proliferation. The mutation reduces m6A modification at canonical motifs and induces aberrant m6A modification at specific sites, perturbing gene expression patterns and cell growth.

Summary: RNA modification, especially the m(6)A modification, plays a crucial role in cancer progression. METTL14, as the central component of the m(6)A methylated transferase complex, acts as both an oncogene and tumor suppressor gene, regulating tumorigenesis and development in various cancers. Abnormal m(6)A levels induced by METTL14 are associated with tumorigenesis, proliferation, metastasis, and invasion.

Summary: m(6)A is a common mRNA modification that regulates cellular mRNA metabolism. It delays the decoding process and increases tRNA drop-off from the ribosome by favoring alternative codon conformations that are rejected by the ribosome.

Summary: This study identifies RNA m(6)A demethylase ALKBH5 as an independent favorable prognostic marker for pancreatic ductal adenocarcinoma (PDAC). ALKBH5 overexpression reduces global RNA m(6)A levels and affects the stability of key regulatory proteins involved in iron metabolism, leading to a protective effect against PDAC.

Summary: The study reveals that the expression levels of m(6)A and its related proteins are lower in bladder cancer. Knockdown of METTL14 reduces the abundance of m(6)A and decreases tumor aggressiveness, suggesting the significant role of m(6)A in bladder cancer progression.

Summary: The development of chemical methods has allowed scientists to study the distribution and functions of RNA modifications. N-6-methyladenosine (m(6)A) is the most abundant internal modification on mRNAs in eukaryotic cells and has been extensively studied. Unlike DNA methylation, m(6)A modification on mRNA is reversible and highly dynamic, influenced by various factors. It plays important roles in biological processes.

Summary: METTL14 promotes global genome repair and suppresses UVB-induced skin tumorigenesis by regulating DDB2 translation through m6A mRNA methylation, and its downregulation by UVB irradiation through NBR1-dependent selective autophagy plays a critical role in skin cancer development.

Summary: The heat shock protein 27 (Hsp27) plays a crucial role in the progression of castration-resistant prostate cancer (CRPC), and an antisense oligonucleotide (ASO) against Hsp27 has been evaluated in clinical trials. This study demonstrates that Hsp27 regulates the expression of the human DEAD-box protein 5 (DDX5) and identifies DDX5 as a potential therapeutic target for CRPC treatment.

Summary: The study demonstrated that murine olfactory ecto-mesenchymal stem cell-derived exosomes can effectively attenuate the progression of experimental Sjogren's syndrome (ESS) by enhancing the immunosuppressive function of myeloid-derived suppressor cells (MDSCs). These exosomes activated the Jak2/Stat3 pathway in MDSCs through IL-6 secretion, and promoted the endogenous production of IL-6 via TLR4 signaling, indicating a potential autocrine pathway for MDSC functional modulation.

Summary: Primary Sjogren's syndrome (pSS) is a chronic autoimmune disease characterized by damage to multiple organs and glands, with dry eyes, dry mouth, and enlarged salivary glands being common clinical manifestations. CD8(+) T lymphocytes have been found to play a significant role in acinar injury in the exocrine glands, contributing to the pathophysiology of the disease. Targeting CD8(+) T cells in treatment strategies can offer promising new approaches for managing pSS.

Summary: Recent research has shown that B cells, traditionally seen as effectors of the immune system, can also act as regulatory B cells (Bregs) with immunosuppressive functions. Bregs exert their effects through various mechanisms such as secretion of anti-inflammatory cytokines and direct cell contact. Maintaining a balance between Bregs and effector B cells is crucial for immune tolerance.

Summary: B cells play a pivotal role in autoimmune diseases, and B cell-activating factor (BAFF) is key in driving autoreactive B cell response. Increased BAFF levels have been observed in patients with autoimmune diseases and mouse models where autoantibody production is prominent. Recent clinical studies have shown BAFF as a potential therapeutic target for treating autoimmune diseases.
