Restoration of RECK expression attenuates liver fibrosis induced by carbon tetrachloride through the Nrf2-MMP9 axis.

Liver fibrosis is a reversible process that can be delayed or even reversed through appropriate intervention during its development. The protein RECK, encoded by the Reck gene, regulates matrix metalloproteinase (MMP) activity and plays a crucial role in extracellular matrix (ECM) degradation and remodeling. Reduced RECK expression is found in various fibrotic tissues.

Cloning of CAT genes in Satsuma mandarin and their expression characteristics in response to environmental stress and arbuscular mycorrhizal fungi.

CitCAT1 and CitCAT2 were cloned and highly expressed in mature leaves. High temperatures up-regulated CitCAT1 expression, while low temperatures and Diversispora versiformis up-regulated CitCAT2 expression, maintaining a low oxidative damage. Catalase (CAT), a tetrameric heme-containing enzyme, removes hydrogen peroxide (HO) to maintain low oxidative damage in plants exposed to environmental stress.

Development of HC-258, a Covalent Acrylamide TEAD Inhibitor That Reduces Gene Expression and Cell Migration.

Evaluation of an Injectable Hydrogel Based on Hyaluronic Acid-Chitosan/β-Glycerophosphate-Loaded Mesenchymal Stem Cells in Enhancing the Therapeutic Efficacy of Myocardial Infarction.

Myocardial infarction (MI), which is due to cardiac dysfunction, results in morbidity and mortality. Moreover, the cellular activity of transplanted mesenchymal stem cells (MSCs) generally limits their therapeutic efficacy in the treatment of MI. Here, inject able hyaluronic acid-chitosan/β-glycerophosphate (HA-CS/β-GP) hydrogel-loaded MSCs are prepared, after which their effects on the treatment of MI are investigated.

MiR-34a suppression targets Nampt to ameliorate bone marrow mesenchymal stem cell senescence by regulating NAD-Sirt1 pathway.

Background: Expansion-mediated replicative senescence and age-related natural senescence have adverse effects on mesenchymal stem cell (MSC) regenerative capability and functionality, thus severely impairing the extensive applications of MSC-based therapies. Emerging evidences suggest that microRNA-34a (miR-34a) has been implicated in the process of MSC senescence; however, the molecular mechanisms with regard to how miR-34a influencing MSC senescence remain largely undetermined.

Sirt3 Attenuates Oxidative Stress Damage and Rescues Cellular Senescence in Rat Bone Marrow Mesenchymal Stem Cells by Targeting Superoxide Dismutase 2.

Oxidative stress is one of the main causes of aging. The process of physiological aging is always accompanied by increased levels of endogenous oxidative stress. Exogenous oxidants have contributed to premature cellular senescence.

Comparison of urine cytology diagnostic reports before and after the implementation of the Paris System classification system in China.

LINK-A lncRNA is upregulated in osteosarcoma and regulates migration, invasion and stemness of osteosarcoma cells.

The present study aimed to investigate the involvement of long intergenic non-coding RNA for kinase activation (LINK-A) long non-coding RNA (lncRNA) in osteosarcoma. Plasma levels of LINK-A lncRNA and transforming growth factor β1 (TGF-β1) were measured by reverse transcription-quantitative polymerase chain reaction and ELISA, respectively. Correlation between LINK-A lncRNA and TGF-β1 was analyzed by Pearson correlation coefficient.

Metabolism: A Novel Shared Link between Diabetes Mellitus and Alzheimer's Disease.

As a chronic metabolic disease, diabetes mellitus (DM) is broadly characterized by elevated levels of blood glucose. Novel epidemiological studies demonstrate that some diabetic patients have an increased risk of developing dementia compared with healthy individuals. Alzheimer's disease (AD) is the most frequent cause of dementia and leads to major progressive deficits in memory and cognitive function.

Vascular smooth muscle cell (VSMC) accumulation and endothelial cell dysfunction are associated with pathogenesis of atherosclerosis. Long noncoding RNA taurine up-regulated gene 1 (TUG1) has been reported to play an important role in cardiovascular diseases, including atherosclerosis. However, the regulatory mechanism underlying TUG1 in atherosclerosis is far from understood.

High glucose inhibits osteogenic differentiation and proliferation of MC3T3‑E1 cells by regulating P2X7.

Diabetes mellitus adversely affects human bones and increases the risk of developing osteoporosis. In the present study, treatment with 30 mmol/l glucose was used to establish a high glucose (HG) cell model in vitro. Plasmids were used to overexpress the P2X purinoceptor 7 (P2X7) gene.

Nicotinamide phosphoribosyltransferase (Nampt) may serve as the marker for osteoblast differentiation of bone marrow-derived mesenchymal stem cells.

Decreased bone volume and strength with aging and enhanced risk of fractures are in part due to reduced number of bone-forming mesenchymal stem cells (MSCs) and cellular dysfunction. In a previous study, we found that osteogenic differentiation of the multipotent and omnipotent preosteoblasts are accompanied by the alterations of intracellular NAD metabolism in which nicotinamide phosphoribosyltransferase (Nampt) plays a regulatory role. The increased Nampt during osteoblast differentiation, the enzyme catalyzing NAD resynthesis from nicotinamide was noted.

Nampt Expression Decreases Age-Related Senescence in Rat Bone Marrow Mesenchymal Stem Cells by Targeting Sirt1.

Senescence restricts the development of applications involving mesenchymal stem cells (MSCs) in research fields, such as tissue engineering, and stem cell therapeutic strategies. Understanding the mechanisms underlying natural aging processes may contribute to the development of novel approaches to preventing age-related diseases or slowing individual aging processes. Nampt is a rate-limiting NAD biosynthetic enzyme that plays critical roles in energy metabolism, cell senescence and maintaining life spans.

Is axillary lymph node dissection necessary after sentinel lymph node biopsy in patients with mastectomy and pathological N1 breast cancer?

Background: The American College of Surgeons Oncology Group (ACOSOG) Z0011 trial reported that axillary lymph node dissection (ALND) did not change the recurrence and overall survival (OS) rates in patients with lumpectomy and one to two positive nodes detected by sentinel lymph node biopsy (SLNB). The aim of this study was to determine whether patients with mastectomy and pathological N1 disease found by SLNB could forego ALND.

Materials And Methods: This is a retrospective study of 214 patients diagnosed with primary invasive breast cancer who were treated by mastectomy and lymph node staging surgery (SLNB or ALND) at the Revlon/UCLA Breast Center between January 2002 and December 2010.

Connexin 43 expression in Sprague-Dawley rat seminiferous epithelium after in utero exposure to flutamide.

This study explored the expression of connexin 43 (Cx43) in the testes of prepubertal Sprague-Dawley (SD) rats following in utero flutamide (Flu) exposure. Connexins constitute the major protein type in gap junctions. Connexin 43, the most prominent connexin family member expressed by testes, is localized at the base of seminiferous tubules in humans and rodents, and may be involved in fertility.
