In spite of improvements in diagnostics and treatment of gastric cancer (GC), it remains the most common malignancy of human digestive system. It is now widely appreciated that long noncoding RNAs (lncRNAs) exert extensive regulatory effects on a spectrum of fundamental biological processes through diverse mechanisms. In this study, we explored the expression level and functional role of lncRNA RP11-138J23.1 in GC. Through bioinformatics analyses and hybridization (ISH), we identified that RP11-138J23.1 was upregulated in GC tissue. Further study showed that RP11-138J23.1 knockdown significantly inhibited cell proliferation and metastatic ability. Whereas, RP11-138J23.1 overexpression could promote tumor cell growth and metastasis . Additionally, loss-of-function assays were used to confirm the role of RP11-138J23.1 . Mechanistically, RP11-138J23.1 exerted its oncogenic functions by binding to HuR protein and increasing stability of VAV3 mRNA. Overall, our study highlights the essential role of RP11-138J23.1 in GC, suggesting that RP11-138J23.1 might be a potent therapeutic target for patients with GC.

Genome imbalance, resulting from varying the dosage of individual chromosomes (aneuploidy), has a more detrimental effect than changes in complete sets of chromosomes (haploidy/polyploidy). This imbalance is likely due to disruptions in stoichiometry and interactions among macromolecular assemblies. Previous research has shown that aneuploidy causes global modulation of protein-coding genes (PCGs), microRNAs, and transposable elements (TEs), affecting both the varied chromosome (cis-located) and unvaried genome regions (trans-located) across various taxa.

Background: Disulfidptosis, a novel cellular death manner, has yet to be fully explored within the context of pulmonary arterial hypertension (PAH). This study aims to identify genes implicated in PAH that are involved in disulfidptosis.
Method: Based on data from the GEO database, this study employed co-expression analysis, Weighted Gene Co-Expression Network Analysis (WGCNA), hub gene identification, and Gene Set Enrichment Analysis (GSEA) to uncover genes associated with PAH and disulfidptosis.

Age-related cataract (ARC) represents a major global cause of visual impairment, with ultraviolet B (UVB) radiation recognized as a primary contributor to oxidative damage in the lens. FOXO3, a key regulator of aging, apoptosis, and oxidative stress-induced cell death, was investigated for its role and regulatory mechanisms in UVB-induced oxidative stress using human lens epithelial cells (HLECs). A progressive decrease in FOXO3 protein expression was observed in the lens capsules across various stages of cataract progression, as well as in UVB-exposed animal models and UVB-treated HLECs.

RNA G-quadruplexes (rG4s) are emerging as vital structural elements involved in processes like gene regulation, translation, and genome stability. Found in untranslated regions of messenger RNAs (mRNAs), they influence translation efficiency and mRNA localization. Additionally, rG4s of long noncoding RNAs and telomeric RNA play roles in RNA processing and cellular aging.

Our study aimed to investigate how this regulatory network influences ISR occurrence and development by modulating inflammation and immunity.
Methods: By utilizing data extracted from the Gene Expression Omnibus (GEO) database, we constructed the lncRNA-miRNA-mRNA regulatory network specific to ISR.
