Small nucleolar RNAs (snoRNAs), a type of non-coding RNA, are widely present in the nucleoli of eukaryotic cells and play an important role in rRNA modification. With the recent increase in research on snoRNAs, new evidence has emerged indicating that snoRNAs also participate in tRNA and mRNA modification. Studies suggest that numerous snoRNAs, including tumor-promoting and tumor-suppressing snoRNAs, are not only dysregulated in tumors but also show associations with clinical prognosis. In this review, we summarize the reported functions of snoRNAs and the possible mechanisms underlying their role in tumorigenesis and cancer development to guide the snoRNA-based clinical diagnosis and treatment of cancer in the future.

Transposase genes are ubiquitous in all domains of life and provide a rich reservoir for the evolution of novel protein functions. Here we report deep evolutionary links between bacterial IS110-family transposases, which catalyse RNA-guided DNA recombination using bridge RNAs, and archaeal/eukaryotic Nop5-family proteins, which promote RNA-guided RNA 2'-O-methylation using C/D-box snoRNAs. On the basis of conservation of protein sequence, domain architecture, three-dimensional structure and non-coding RNA features, alongside phylogenetic analyses, we propose that programmable RNA modification emerged through the exaptation of components derived from IS110-like transposons.

Objective: Gastric cancer (GC) is a globally common cancer characterized by high incidence and mortality worldwide. Advances in the molecular understanding of GC provide promising targets for GC diagnosis and therapy. Long non-coding RNAs (lncRNAs) and their downstream regulators are regarded to be implicated in the progression of multiple types of malignancies.

Background: The dysregulation of ribosome biogenesis has been extensively identified in various cancers, making it emerge as a hallmark of malignant cells. This highlights the potential of targeting ribosome biogenesis as an effective approach for treating cancer patients. Although chemotherapy drugs including doxorubicin and cisplatin often target ribosome biogenesis to induce DNA damage or inhibit tumor cell proliferation, they are associated with significant side effects.

Background: Extracellular vesicles (EVs) are essential for cell-to-cell communication because they transport functionally active molecules, including proteins, RNA, and lipids, from secretory cells to nearby or distant target cells. Seminal plasma contains a large number of EVs (sEVs) that are phenotypically heterogeneous. The aim of the present study was to identify the RNA species contained in two subsets of porcine sEVs of different sizes, namely small sEVs (S-sEVs) and large sEVs (L-sEVs).

Ischemic stroke (IS) remains a leading cause of disability and mortality worldwide, and inflammation and oxidative stress play significant roles in its pathogenesis. This study investigates the effects of dihydromyricetin (DHM) on IS using RT-qPCR and western blot with SH-SY5Y cells, focusing on its effects on the small nucleolar RNA host gene 10 (SNHG10)/microRNA (miR)-665/Ras association domain family member 5 (RASSF5) axis and nuclear factor-kappa B (NF-κB) signaling. In addition, the effects of the SNHG10/miR-665/RASSF5 axis on SH-SY5Y cell activity, apoptosis, oxidative stress, and inflammatory markers were analyzed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, flow cytometry, and enzyme-linked immunosorbent assays.
