RNA modifications play crucial roles in immune system development and function, with dynamic changes essential for diverse cellular processes. Innovative profiling technologies are invaluable for understanding the significance of these modifications in immune cells, both in healthy and diseased states. This review explores the utility of such technologies in uncovering the functions of RNA modifications and their impact on immune responses. Additionally, it delves into the mechanisms through which aberrant RNA modifications influence the tumor microenvironments immune milieu. Despite significant progress, several outstanding research questions remain, highlighting the need for further investigation into the molecular mechanisms underlying RNA modification's effects on immune function in various contexts.

Gastric cancer (GC) is a malignant tumor originating from the epithelial cells of the gastric mucosa. The 5-methylcytosine (mC) modification refers to the addition of a methyl group to the fifth carbon atom of cytosine in RNA molecules. This study aimed to investigate the role of NOL1/NOP2/SUN domain (NSUN)6 in GC and its underlying molecular mechanisms.

Background: The dysregulation of long-chain noncoding RNAs (lncRNAs) causes several complex human diseases including neurodegenerative disorders across the globe.
Methods And Results: This study aimed to investigate lncRNA expression profiles of Withania somnifera (WS)-treated human neuroblastoma SK-N-SH cells at different timepoints (3 & 9 h) and concentrations (50 & 100 µg/mL) using RNA sequencing. Differential gene expression analysis showed a total of 4772 differentially expressed lncRNAs, out of which 3971 were upregulated and 801 were downregulated compared to controls.

5-methylcytosine (m5C) methylation is a post-transcriptional modification of RNAs, and its dysregulation plays pro-tumorigenic roles in lung adenocarcinoma (LUAD). Here, this study elucidated the mechanism of action of NSUN2, a major m5C methyltransferase, on LUAD progression. mRNA expression was analyzed by quantitative PCR.

Gliomas are the most common primary malignant tumors of the central nervous system (CNS), and despite progress in molecular diagnostics and targeted therapies, their prognosis remains poor. In recent years, immunotherapy has emerged as a promising treatment modality in cancer therapy. However, the inevitable immune evasion by tumor cells is a key barrier affecting therapeutic efficacy.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease, the incidence of which continues to rise globally, and existing therapeutic options are limited by low drug bioavailability and systemic side effects. In this study, we systematically investigated the challenges of the special gastrointestinal environment of UC patients for oral drug delivery, such as extreme pH, degradation by digestive enzymes, metabolism of intestinal flora and obstruction of the intestinal mucosal barrier, and summarized the potential of plant-derived Exosome-like Nanovesicles (PELNs) as a novel delivery system. PELNs are produced by plant cells and mainly consist of proteins, RNA, lipids and plant active molecules.
