Extracellular Vesicles Carrying RUNX3 Promote Differentiation of Dental Pulp Stem Cells.

Background: This study aims to clarify the mechanism underlying dental pulp cells-extracellular vesicles (DPC-EVs) carrying runt-related transcription factor 3 (RUNX3) in mediating odontogenic differentiation of dental pulp stem cells (DPSCs) with the involvement of miR-30a-5p-regulated NOTCH1.

Methods: Extracellular vesicles (EVs) were isolated from human DPSCs, and identified using transmission electron microscopy, and nanoparticle tracking analysis. PBS, EVs, or EV inhibitor GW4869 was added to DPSCs for co-culture, whilst odontogenic differentiation was assessed in terms of ratio of mineralized nodules and expression odontoblast differentiation markers.

Burden of diabetes attributable to dietary cadmium exposure in adolescents and adults in China.

At present, the health risk assessment of cadmium exposure has become a major focus of environmental health research. However, there is still a lack of systematic research on the burden of diabetes (DM) attributable to dietary cadmium exposure in adolescents and adults in China. Using the top-down method, the blood cadmium level (B-Cd) of Chinese adolescents and adults from 2001 to 2023 was combined with the relative risk (RR) of cadmium-induced diabetes to calculate the population attribution score (PAF).

Anti-TNF Therapy Regulates Phagosome Pathway by Inhibiting NCF4 Expression to Treat Ankylosing Spondylitis.

Objectives: Ankylosing spondylitis (AS) is challenging to diagnose in its early stages, and treatment options are limited.

Methods: GEO2R analysis and weighted gene co-expression network analysis (WGCNA) were used to identify DEGs and key modules. Kyoto Encyclopedia of Genes and Genomes analysis and Protein-protein interactions were used to identify core genes.

Experimental study of miR-503 regulating the activity as well as the function of degenerated human nucleus pulposus cells of the intervertebral disc through inhibiting Wnt pathway.

Objectives: To preliminarily explore miR-503 in human degenerative disc nucleus pulposus cell effects as well as mechanisms.

Methods: We utilized bioinformatics analysis to determine the miRNA differential expression as well as key signal pathways existing in human nucleus pulposus cells of the degenerative intervertebral discs. Human degenerative disc nucleus pulposus cell model was cultured and established .

Gallic acid regulates immune response in a mouse model of rheumatoid arthritis.

Introduction: Previous studies revealed that gallic acid (GA) exerts anti-inflammation and immuno-regulatory properties. This study aims to explore the pharmacological activities of GA in collagen-induced arthritis (CIA) mouse model.

Methods: Male DBA/1J mice were used to construct the CIA model.

Depleted Long Noncoding RNA GAS5 Relieves Intervertebral Disc Degeneration via microRNA-17-3p/Ang-2.

Intervertebral disc degeneration (IVDD) remains a clinical challenge and requires more effective therapeutic targets. Long noncoding RNAs (lncRNAs) have emerged as critical modulators of multiple biological processes, such as cell proliferation and extracellular matrix (ECM) remodeling. Accordingly, the current study sets out to explore the influence of the lncRNA growth arrest-specific 5 (GAS5) on IVDD and investigate the possible involvement of microRNA-17-3p (miR-17-3p)/Angiopoietin-2 (Ang-2) axis.

Triptolide ameliorates osteoarthritis by regulating nuclear factor kappa B-mediated inflammatory response.

Objectives: Osteoarthritis (OA) is a joint degenerative disease that commonly occurs in older people and affect the quality of life. Triptolide (TPL), a compound derived from Tripterygium wilfordii, has been shown to exhibit anti-inflammatory properties. Here, we investigated the therapeutic effect of TPL on the experimental OA as well as the underlying molecular mechanisms.

Iguratimod promotes transformation of mononuclear macrophages in elderly patients with rheumatoid arthritis by nuclear factor-κB pathway.

Background: The role of macrophages in rheumatoid arthritis (RA) and its mechanism have attracted much attention in RA pathogenesis. Macrophages accumulate in the synoviums of RA, and the proportion of M1 type pro-inflammatory macrophages is higher than that of M2 type anti-inflammatory macrophages, leading to the secretion of inflammatory molecules and the aggravation of inflammatory reaction, which has made macrophages a potential target of RA drugs. Iguratimod is a kind of cyclo-oxygenase-2 inhibitor that affects macrophage polarity.

LncRNA NOP14-AS1 Promotes Tongue Squamous Cell Carcinoma Progression by Targeting MicroRNA-665/HMGB3 Axis.

Purpose: The expression profile, clinical effects, and detailed roles of NOP14 antisense RNA 1 (NOP14-AS1) in tongue squamous cell carcinoma (TSCC) remain ambiguous and need to be further explored. Thus, this work was initiated to offer further solid evidence regarding the expression and roles of NOP14-AS1 in TSCC. Furthermore, additional efforts were exerted to reveal the molecular events by which NOP14-AS1 affects the malignant behaviours of TSCC.

DDIT3 modulates cancer stemness in gastric cancer by directly regulating CEBPβ.

Objectives: Cancer stem cells (CSCs) have been identified to correlate with the initiation and metastasis of tumours, and DNA damage-inducible transcript 3 (DDIT3) is associated with the poor prognosis in gastric cancer (GC). However, whether DDIT3 mediates CSCs stemness in GC is still unclear.

Methods: Microarray analysis and Gene Ontology (GO) were conducted to identify the differentially expressed genes in GC tissues from GC patients.

Low dose of indomethacin and Hedgehog signaling inhibitor administration synergistically attenuates cartilage damage in osteoarthritis by controlling chondrocytes pyroptosis.

Blockade of Hedgehog signaling can prevent osteoarthritis (OA) syndromes. However, the amelioration of related inflammation condition is limited. The purpose of this study was to observe the effect of combined use of Hedgehog signaling inhibitor GANT-61 and common clinical anti-inflammatory drug indomethacin on cartilage injury and inflammation in experimental OA mice.
