As a key protein, Tripartite motif family-like 2 (TRIML2) is crucial to the p53-mediated apoptosis and is correlated with tumorigenesis. Emerging evidence showed that long non-coding RNAs (lncRNAs) play roles in the malignant progression of gastric cancer (GC). However, the function and underlying mechanism of LINC02679 in GC are still unclear. In this study, we detected the differentially expressed lncRNA, LINC02679, which was associated with the progression of GC. Herein, we showed that LINC02679 was overexpressed in GC tissues and correlated with poor prognosis, which aggravated GC proliferation, migration, and invasion. Mechanistically, LINC02679 sponged miR-5004-3p to promote the expression of TRIML2, regulating GC tumorigenesis and progression. Moreover, TRIML2 affected the proliferation, migration, and invasion of GC cells through TGF-β1/Smads signaling pathway. Overall, our findings proved a new mechanism and provided a promising strategy for precise therapy of GC by targeting LINC02679.

Patients with inflammatory bowel disease (IBD) demonstrate varying expression levels of long non-coding RNAs (lncRNAs) in their intestinal mucosa, which can potentially impact the function of the intestinal barrier. This impact may occur through the modulation of epithelial cell apoptosis, alteration of intestinal mucosal barrier permeability, and enhancement of inflammatory responses. The objective of this study was to explore the role and underlying mechanisms of the downregulated lncRNA ANRIL in modulating intestinal barrier function in IBD. Notably, ANRIL was found to be significantly downregulated in patients diagnosed with ulcerative colitis (UC), correlating strongly with disease progression. The overexpression of ANRIL in mice treated with dextran sulfate sodium (DSS) resulted in a significant reduction in colonic damage. This was accompanied by the suppression of pro-inflammatory cytokines such as IL-6, TNF-α, and IL-1β, and an improvement in intestinal barrier function. Transcriptome sequencing following overexpression of ANRIL revealed a significant enrichment of the NF-κB signaling pathway. In both DSS-induced mouse colitis and LPS-induced FHC cell models, the upregulation of ANRIL effectively suppressed the activation of the NF-κB pathway. Furthermore, our findings demonstrated that ANRIL competes with YY1 for binding, thereby inhibiting the interaction between YY1 and p65 subunit of NF-κB. This disruption in interaction results in the suppression of transcriptional activation of NF-κB p65, leading to a reduced expression of inflammatory cytokines and the promotion of intestinal barrier function in IBD.Additionally, we identified a negative feedback loop involving ANRIL and p65, wherein p65 binds to the ANRIL promoter, promoting ANRIL expression. In summary, the ANRIL/p65 negative feedback loop represents a potential therapeutic target for protecting intestinal barrier function in IBD.

As the earliest aging organ in the reproductive system, the ovary has both reproductive and endocrine functions, which are closely related to overall female health. The exact pathogenesis of ovarian aging (OA) remains incompletely understood, with granulosa cells (GCs) dysfunction playing a significant role in this process. Recent advancements in research and biotechnology have highlighted the importance of non-coding RNAs (ncRNAs), including micro RNAs, long non-coding RNAs, and circular RNAs, in regulating the biological functions of GCs through gene expression modulation. This paper provides a comprehensive overview of the role of ncRNAs in various cellular functions such as apoptosis, autophagy, proliferation, and steroid synthesis in GCs, and explores the underlying regulatory mechanisms. Additionally, the therapeutic potential of ncRNAs, particularly those carried by exosomes derived from mesenchymal stem cells, in delaying OA is discussed. Understanding the regulatory mechanisms of ncRNAs in GC function and the current progress in this field is crucial for identifying effective biomarkers and therapeutic targets, ultimately aiding in the early diagnosis, prognostic assessment, and individualized treatment of OA.

Age estimation is a critical aspect of human identification. Traditional methods, reliant on morphological examinations, are often suitable for living subjects. However, there are relatively few studies on age estimation based on biological samples, such as blood. Recent advancements have concentrated on DNA methylation for forensic age prediction. However, to explore further possibilities, this study investigated microRNAs (miRNAs) as alternative molecular markers for age estimation. Peripheral blood samples from 127 healthy individuals were analyzed for miRNA expression using small RNA sequencing. Lasso regression selected 103 candidate miRNAs, and Shapley additive explanations (SHAP) analysis identified 38 key miRNAs significant for age prediction. Five machine learning models were developed, with the elastic net model achieving the best performance (MAE of 4.08 years) on the testing set, surpassing current miRNA age estimation results. Additionally, we observed significant changes in the expression levels of miRNAs in healthy individuals aged 48–52 years. This study demonstrated the potential of blood miRNA biomarkers in age prediction and provides a set of miRNA markers for developing more accurate age prediction methods.

Objective
Recent evidence underscores the pivotal role of long noncoding RNAs (lncRNAs) in orchestrating bone remodeling and skeletal homeostasis by harmonizing osteoblast and osteoclast development. Notably, the oncogenic lncRNA, Hottip, implicated in osteogenesis regulation, remains insufficiently elucidated. This study aims to delineate Hottip's role in bone remodeling and skeletal homeostasis.
Methods
Hottip knockout mice were generated to discern its impact on bone metabolism. In vitro experiments probed cellular mechanisms influenced by Hottip, while molecular interactions were explored to understand its basis. The therapeutic potential of Hottip overexpression was investigated through in vivo experiments.
Results
Hottip knockout mice displayed disrupted bone metabolism, aberrant tissue, and compromised quality, leading to delayed fracture healing. In vitro, Hottip knockdown impeded osteoblast differentiation, while promoting osteoclast differentiation, with converse effects upon Hottip overexpression. Mechanistically, Hottip physically interacted with EZH2, inducing its degradation and enhancing osteogenic gene transcription by suppressing H3K9me3 and H3K27me3. In vivo experiments validated Hottip overexpression's potential to promote bone regeneration and hasten fracture healing.
Conclusion
In summary, this study identifies Hottip as a critical regulator in osteoblast and osteoclast differentiation, crucial for maintaining skeletal homeostasis. Hottip emerges as a promising therapeutic target for enhancing bone regeneration. These findings contribute valuable insights into lncRNA-mediated mechanisms governing skeletal dynamics.

MicroRNAs (miRNAs) are small non-coding RNAs that act as critical regulators of gene expression by repressing mRNA translation. The role of miRNAs in cell physiology spans from cell cycle control to cell proliferation and differentiation, both during development and in adult tissues. Accordingly, dysregulated expression of miRNAs has been reported in several diseases, including cancer, where miRNAs can act as oncogenes or oncosuppressors. Of note, miRNA signatures are also under investigation for classification, diagnosis, and prognosis of cancer patients.
Brain tumours are primarily associated with poor prognosis and high mortality, highlighting an urgent need for novel diagnostic, prognostic, and therapeutic tools. Among miRNAs investigated in brain tumours, miR-326 has been shown to act as a tumour suppressor in adult and paediatric brain cancers. In this review, we describe the role of miR-326 in malignant as well as benign cancers originating from brain tissue. In addition, since miR-326 expression can be regulated by other non-coding RNA species, adding a further layer of regulation in the cancer-promoting axis, we discuss this miRNA's role in targeted therapy for brain cancers.

Matrix metalloproteinases (MMPs) cleave proteins of extracellular matrix thus facilitating cellular invasion and cancer progression. High MMP-2 activity is frequently reported in several diseases including endometriosis and cancer. Endometriosis, though benign causing pain and infertility, rarely culminate into ovarian cancer. New diagnostic markers are needed for early diagnosis and proper therapeutic avenues since the only diagnostic method is laparoscopy to date. Emerging evidence shows the importance of MMP activity and involvement of noncoding RNA, e.g. miRNA thereon. We investigated the role of miRNA-34a in MMP-2-mediated regulation of invasion and tumorigenesis in endometriosis. Database analysis showed a decreased miRNA-34a in different gynecological malignancies. qRT-PCR with human endometriotic and control tissues revealed a significant elevation in MMP-2 activity with downregulated miR-34a in diseased individuals proving an inverse correlation between miRNA-34a and MMP-2. Luciferase assay in SK-OV-3 cells demonstrated that miRNA-34a-5p directly binds the 3′UTR of the MMP-2 promoter to reduce its transcription followed by suppression of invasion. The zymographic assay also showed a reduced MMP-2 activity upon miR-34a treatment in End1/E6E7 and SK-OV-3 cells. We also found that miRNA-34a-5p inhibits invasion, migration, colony/spheroid formation, and stemness of the cells thereby reducing in vitro tumorigenesis. Subsequently, the immunoblotting results confirmed that MMP-2, and mesenchymal markers like n-cadherin, vimentin, and slug expression were downregulated, whereas the e-cadherin was upregulated in the cells treated with miRNA-34a mimic. Our study demonstrates the direct binding of miR-34a-5p with the MMP-2 gene's 3′UTR and thus repressed its transcription as well as suppressing endometriosis progression.

Background
Alu-mediated p21 transcriptional regulator (APTR) overexpression is detected in different human cancers; however, few reports have investigated APTR gene amplification conditions. Furthermore, whether APTR amplification is related to glioma malignancy and the underlying mechanism remain unknown.
Methods
APTR amplification and expression levels in 153 glioma samples were analyzed using qPCR. Correlations between APTR and patient prognosis were evaluated using Kaplan-Meier survival and COX regression analyses. Both in vitro and in vivo phenotypic assays were performed to confirm the carcinogenic effects of APTR in glioblastoma (GBM) cells. RNA-sequencing and RNA immunoprecipitation and luciferase reporter assays were performed to confirm APTR as a competing endogenous RNA (ceRNA) and to identify the downstream axis of APTR.
Results
Our results suggest that APTR amplification and overexpression are novel independent diagnostic biomarkers for predicting poor prognosis in patients with gliomas. APTR knockdown significantly repressed the proliferation and invasion of GBM cells, both in vitro and in vivo. APTR was demonstrated to absorb miR-6734-5p and upregulate TCF7 and LEF1 expression. Taken together, these results suggest that APTR promotes the malignant phenotypes of GBM by inducing TCF7 and LEF1 expression.
Conclusion
We identified APTR as a novel prognostic biomarker in patients with gliomas and confirmed that APTR is a ceRNA that promotes glioma progression via the APTR/miR-6734-5p/TCF7/LEF1 axis.

This study found that in patients with SLE (n = 5), lethal (let)-7f-5p expression was significantly downregulated in peripheral blood mononuclear cells. Further, high-throughput RNA sequencing was used to mine the differential transcriptome expression in renal tissue exosomes of systemic lupus erythematosus (SLE)-prone mice, and bioinformatics was utilized to analyze non-coding RNAs and coding RNAs in exosomes for their possible roles in SLE. In renal tissues of MRL/lpr SLE-prone mice with exosomes and Pristane-induced SLE mice, we also demonstrated aberrant expression levels of microRNA (miRNA) let-7f-5p. Meanwhile, in the macrophage inflammation model, the expression levels of let-7f-5p were downregulated, that of guanylate binding protein (Gbp2 and Gbp7) were upregulated, and the inflammatory state of macrophages was alleviated following transfection with the let-7f-5p mimic. Co-culturing mesenchymal stem cells with a macrophage model of inflammation resulted in increased let-7f-5p expression and downregulated inflammatory factors, Gbp2 and Gbp7 expression in macrophages. Dual luciferase reporter gene assays confirmed that let-7f-5p directly binds to the 3′ UTR of Gbp7 to regulate its expression. Let-7f-5p regulation of the Gbp family is involved in SLE pathogenesis and is a biomarker associated with the inflammatory response with potential clinical applications.
