چکیده

Mycoplasma pneumoniae pneumonia (MPP) is a type of induced by M. (MP) infection. The present study investigated the effect long non‑coding RNA growth arrest‑specific 5 (GAS5) in MPP and underlying molecular mechanism this. expression GAS5, microRNA‑222‑3p, (miR‑222‑3p) tissue inhibitor metalloproteinases‑3 (TIMP3) was using reverse transcription‑quantitative PCR. Lipid‑associated membrane protein (LAMP)‑induced THP‑1 cells were used to model MPP. viability LAMP‑induced analyzed an MTT assay. Expression levels interleukin (IL)‑1β, IL‑6 tumor necrosis factor‑α (TNF‑α) pro‑inflammatory cytokines, anti‑inflammatory cytokine heme oxygenase‑1 (HO‑1) measured ELISA. A dual‑luciferase reporter assay assessed associations among miR‑222‑3p TIMP3. GAS5 TIMP3 downregulated upregulated. GAS5‑overexpression increased cells. upregulation decreased IL‑1β, IL‑6, TNF‑α HO‑1 directly interacted with miR‑222‑3p. target or TIMP3‑knockdown reversed promotion on cell as well inhibitory inflammation caused regulating miR‑222‑3p/TIMP3 axis. These results demonstrated potential therapeutic for treatment.

Long Noncoding RNA MHRT Protects Cardiomyocytes against H2O2-Induced Apoptosis

Acute myocardial infarction (AMI) remains a leading cause of morbidity and mortality worldwide. The exploration of new biomarkers with high sensitivity and specificity for early diagnosis of AMI therefore becomes one of the primary task. In the current study, we aim to detect whether there is any heart specific long noncoding RNA (lncRNA) releasing into the circulation during AMI, and explore i...

Hydrogen sulfide protects coriander seedlings against copper stress by regulating the ascorbate-glutathione cycle, in leaves

&nbsp; Heavy metals are the cause of major abiotic stresses in plants and a principal contributor to environmental pollution in recent decades. This study investigated the effects of exogenous hydrogen sulfide on the ascorbate-glutathione cycle in the leaves of coriander seedlings under copper stress. Results showed that copper stress not only reduced APX and GR activities but also decreas...

Circulating long noncoding RNA GAS5 levels are correlated to prevalence of type 2 diabetes mellitus.

BACKGROUND Diabetes mellitus (DM), a metabolic disease, is characterized by impaired fasting glucose levels. Type 2 DM is adult onset diabetes. Long non-coding RNAs (lncRNAs) regulate gene expression and multiple studies have linked lncRNAs to human diseases. METHODS Serum samples obtained from 96 participating veterans at JAH VA were deposited in the Research Biospecimen Repository. We used ...

Corylin Suppresses Hepatocellular Carcinoma Progression via the Inhibition of Epithelial-Mesenchymal Transition, Mediated by Long Noncoding RNA GAS5

Corylin is a flavonoid extracted from the nuts of Psoralea corylifolia L. (Fabaceae), which is a widely used anti-inflammatory and anticancer herb in China. Recent studies revealed antioxidant, anti-inflammatory, and bone differentiation-promoting effects of corylin. However, there are no studies examining the anticancer activity of corylin. In this study, we used cells and animal models to exa...
