Abstract RNA modifications are dynamic and reversible chemical on substrate that regulated by specific modifying enzymes. They play important roles in the regulation of many biological processes various diseases, such as development cancer other diseases. With help advanced sequencing technologies, role has caught increasing attention human diseases scientific research. In this review, we briefly summarized basic mechanisms several common modifications, including m6A, m5C, m1A, m7G, Ψ, A-to-I editing ac4C. Importantly, discussed their potential functions cancer, neurological disorders, cardiovascular metabolic genetic developmental well immune disorders. Through “writing-erasing-reading” mechanisms, regulate stability, translation, localization pivotal disease-related mRNAs to manipulate disease development. Moreover, also highlighted review all currently available RNA-modifier-targeting small molecular inhibitors or activators, most which designed against m6A-related enzymes, METTL3, FTO ALKBH5.

In recent years, N7-methylguanosine (m7G) methylation, originally considered as messenger RNA (mRNA) 5′ caps modifications, has been identified at defined internal positions within multiple types of RNAs, including transfer ribosomal miRNA, and mRNAs. Scientists have put substantial efforts to discover m7G methyltransferases methylated sites in RNAs unveil the essential roles modifications regulation gene expression determine association dysregulation various diseases, neurological disorders. Here, we review findings regarding distribution, abundance, biogenesis, modifiers, functions modifications. We also provide an up-to-date summary detection profile mapping techniques, databases for validated predicted sites, web servers methylation prediction. Furthermore, discuss pathological METTL1/WDR-driven Last, outline a roadmap future directions trends modification research, particularly central nervous system.

Most of our transcribed RNAs are represented by non-coding sequences. Long (lncRNAs) transcripts with no or very limited protein coding ability and a length >200nt. They can be epigenetically modified. N6-methyladenosine (m6A), N1-methyladenosine (m1A), 5-methylcytosine (m5C), 7-methylguanosine (m7G) 2’-O-methylation (Nm) some the lncRNAs epigenetic modifications. The modifications RNA controlled three classes enzymes, each playing role in specific phase modification. These enzymes defined as “writers”, “readers” “erasers”. m6A m5C most studied RNA. alter structure properties, thus modulating functions interactions lncRNAs. aberrant expression several is linked to development variety cancers signatures m6A- m5C-related increasingly recognized potential biomarkers prognosis, predictors disease stage overall survival.

Abstract Cancer is one of the leading causes death worldwide, and more effective ways attacking cancer are being sought. immunotherapy a new therapeutic method after surgery, radiotherapy, chemotherapy, targeted therapy. aims to kill tumor cells by stimulating or rebuilding body's immune system, with specific efficiency high safety. However, only few patients respond due complex variable characters escape, behavior regulatory mechanisms need be deeply explored from dimensions. Epigenetic modifications, metabolic modulation, cell‐to‐cell communication key factors in cell adaptation response microenvironment. They collectively determine state function through modulating gene expression, changing energy nutrient demands. In addition, engage networks other components, which mediated exosomes, cytokines, chemokines, pivotal shaping progression response. Understanding interactions combined effects such multidimensions modulation important for revealing failure developing targets strategies.

It is apparent that various functional units within the cellular machinery are derived from RNAs. The evolution of sequencing techniques has resulted in significant insights into approaches for transcriptome studies. Organisms utilize RNA to govern systems, and a heterogeneous class RNAs involved regulatory functions. In particular, increasingly recognized participate intricately functioning across almost all levels biological systems. These systems include those mediating chromatin arrangement, transcription, suborganelle stabilization, posttranscriptional modifications. Any exhibiting activity can be termed typically represented by noncoding RNAs, which constitute substantial portion genome. function based on principle structural changes through cis and/or trans regulation facilitate mutual RNA‒RNA, RNA‒DNA, RNA‒protein interactions. not been clearly elucidated whether identified deep actually anticipated mechanisms. This review addresses dominant properties at layers covers activities, dynamics, modifications, associated molecules, further challenges related therapeutics learning.

Abstract Tumor-associated lncRNAs regulated by epigenetic modification switches mediate immune escape and chemoresistance in ovarian cancer (OC). However, the underlying mechanisms concrete targets have not been systematically elucidated. Here, we discovered that methylation modifications played a significant role regulating cell infiltration sensitizing OC to chemotherapy modulating immune-related (irlncRNAs), which represent tumor status. Through deep analysis of TCGA database, prognostic risk model incorporating four methylation-related (mrlncRNAs) irlncRNAs was constructed. Twenty-one mrlncRNA/irlncRNA pairs were identified significantly related overall survival (OS) patients. Subsequently, selected construct signature predictive OS indicative infiltration, verified robustness an internal validation set. The score independent factor for prognosis, demonstrated via multifactorial Cox regression nomogram. Moreover, scores negatively expression CD274, CTLA4, ICOS, LAG3, PDCD1, PDCD1LG2 correlated with CD8 + , CD4 Treg tumor-infiltrating cells. In addition, high-risk associated higher IC50 value cisplatin, worse clinical outcome. Next, competing endogenous RNA (ceRNA) network signaling pathway controlling T cells explored based on lncRNA model, suggested potential therapeutic target immunotherapy. Overall, this study constructed pairing mrlncRNAs revealed critical FTO/RP5-991G20.1/hsa-miR-1976/MEIS1 function enhancing anticancer therapy.
