BACKGROUND: Osteoarthritis is the most common bone-joint disease in middle and older people all over the world. Tanshinone IIA (Tan IIA) is the main lipophilic diterpenoid isolated from the root of Salvia miltiorrhiza Bunge (Lamiaceae). This study analyzed the protective effects of Tan IIA on lipopolysaccharide (LPS)-induced murine chondrogenic ATDC5 cell inflammatory injury model. METHODS: Cell viability was assessed using cell counting kit-8 (CCK-8) assay. Cell apoptosis was detected using Annexin V-FITC/PI staining...

BACKGROUND: Nicotinamide riboside (NR) is a nicotinamide adenine dinucleotide (NAD+ ) precursor which is present in foods such as milk and beer. It was reported that NR can prevent obesity, increase longevity, and promote liver regeneration. However, whether NR can prevent ethanol-induced liver injuries is not known. This study aimed to explore the effect of NR on ethanol induced liver injuries and the underlying mechanisms. METHODS: We fed C57BL/6 J mice with Lieber-DeCarli ethanol liquid diet with or without 400 mg/kg·bw NR for 16 days...

β-tricalcium phosphate (β-TCP) is well known as a resorbable bone repair material due to its inherent excellent biocompatibility and osteoconductivity. However, β-TCP is encountered with osteostimulation-deficiency and poor mechanical strength because of poor sinterability. Herein, we prepared novel β-TCP composite ceramics (TCP/SPGs) by introducing strontium-containing phosphate-based glass (SPG; 45P2 O5 -32SrO-23Na2 O) as sintering additive. The SPG helped to achieve efficient liquid-phase sintering of β-TCP at 1100 °C...

Phagocytosis and apoptosis are key cellular innate immune responses against bacteria and virus in invertebrates. Class B scavenger receptors (SRBs), which contain a CD36 domain, are critical pattern recognition receptors (PRRs) of phagocytosis for bacteria and apoptotic cells. In the present study, we identified a member of SRB subfamily in mud crab Scylla paramamosain, named Sp-SRB. The full-length cDNA of Sp-SRB is 2593 bp with a 1629 bp open reading frame (ORF) encoding a putative protein of 542 amino acids, and predicted to contain a CD36 domain with two transmembrane regions at the C- and N-terminals...

Angiogenesis after ischemic stroke contributes to the restoration of blood supply in the ischemic zone. Strategies to improve angiogenesis may facilitate the function recovery after stroke. Growing evidence shows that proteasome inhibitors enhance angioneurogenesis and induces a long-term neuroprotection after cerebral ischemia in rodents' models. We have previously reported that inhibition of the immunoproteasome subunit low molecular mass peptide 2 (LMP2) offers a strong neuroprotection in ischemic stroke rats...

With the global rising prevalence of gestational diabetes (GDM), an adaptable, economical approach to nutrition therapy that effectively controls maternal glycemia while promoting normal fetal growth will have far-reaching implications. The conventional focus has been to rigidly limit all types of carbohydrate. While controlling glucose, this approach fosters maternal anxiety and is a primary barrier to adherence. Many mothers substitute fat for carbohydrate, which may unintentionally enhance lipolysis, promote elevated free fatty acids (FFA), and worsen maternal insulin resistance (IR)...

Goat myosin light chain 6 (gMYL6) is a constituent of certain extracted immunization-induced goat anti-cancer bioactive peptides (ACBPs). However, little is known about its activity onto NK cells which are the basic cellular attackers in cancer immunotherapy for patients with malignancies. Because of the complicated extraction process and low yield of gMYL6 out of the goat ACBPs' mixture, the Nano-flow liquid chromatography and C-terminal polycationic tag expression strategy were used to identify and enrich the peptide to investigate its bioactivity against cancers/tumors...

While chemotherapy is an important and widely used therapeutic for cancer, it may facilitate cancer metastasis. Herein, we report that human lung cancer cells exerted higher invasion and metastasis after chemotherapy. In a human lung cancer xenograft model, chemotherapy promotes the cancer invasion and metastasis in HMGB1-dependent manner. Further studies identify HMGB1-containing nucleosome from chemotherapy-induced apoptotic cancer cells as an effective factor. Such nucleosome functions through TLR4 and TLR9 to drive cancer invasion and metastasis...

Muscle cells secrete numerous molecules that function as endocrine hormones and regulate the functions of distant organs. Myelination in the central nervous system (CNS) is regulated by peripheral hormones. However, the effects of muscle-derived molecules on myelination have not been sufficiently analyzed. In this study, we show that muscle-releasing factors promote proliferation of oligodendrocyte precursor cells (OPCs), which is an element of myelination process. Supernatants of mouse myotube cultures stimulated bromodeoxyuridine (BrdU) incorporation into mouse OPCs...

The present study was designed to examine the protection of D-β-hydroxybutyrate (BHB) against ischemia/reperfusion (I/R) injury in heart and investigate its underlying mechanism. Male adult mice were exposed to 30min of ischemia and 24h of reperfusion. Osmotic pumps were implanted subcutaneously 5min before reperfusion for continuous delivery of the exogenous BHB (1.6mmol/kg/24h). Treatment with BHB reduced infarct size and levels of cardiac troponin I, creatine kinase and lactate dehydrogenase in serum, attenuated apoptosis in myocardium, and preserved cardiac function of I/R mice...

BACKGROUND: Self-determination theory (SDT) has been used to predict children's physical activity and well-being. However, few school-based SDT intervention studies have been conducted, and no research exists with children of low socio-economic status (SES). Therefore, SDT-derived needs-supportive teaching techniques informed the design and analyses of the Healthy Choices Programme (HCP). The aim was to determine if the HCP could enhance moderate-to-vigorous physical activity (MVPA) and well-being among children of low SES through increasing autonomy-support, needs satisfaction and intrinsic motivation...

Recurrent chromosomal aberrations have led to the discovery of oncogenes or tumour suppressors involved in carcinogenesis. Here we characterized an oncogenic long intergenic non-coding RNA in the frequent DNA-gain regions in hepatocellular carcinoma (HCC), LINC01138 (long intergenic non-coding RNA located on 1q21.2). The LINC01138 locus is frequently amplified in HCC; the LINC01138 transcript is stabilized by insulin like growth factor-2 mRNA-binding proteins 1/3 (IGF2BP1/IGF2BP3) and is associated with the malignant features and poor outcomes of HCC patients...

Pancreatic β-cell Tcf7l2 deletion or its functional knockdown suggested the essential role of this Wnt pathway effector in controlling insulin secretion, glucose homeostasis, and β-cell gene expression. As the LIM homeodomain protein Isl1 is a suggested Wnt pathway downstream target, we hypothesize that it mediates metabolic functions of Tcf7l2. We aimed to determine the role of Isl1 in mediating the function of Tcf7l2 and the incretin hormone GLP-1 in pancreatic β-cells. Effect of dominant negative TCF7L2 (TCF7L2DN) mediated Wnt pathway functional knockdown on Isl1 expression was determined in βTCFDN mouse islets and in the rat insulinoma cell line INS-1 832/13...

Many enveloped viruses enter cells through the endocytic network, from which they must subsequently escape through fusion of viral and endosomal membranes. This membrane fusion is mediated by virus-encoded spikes that respond to the changing endosomal environment, which triggers conformational change in the spike that initiate the fusion process. Several fusion triggers have been identified and include pH, membrane composition and endosome-resident proteins and these cues dictate when and where viral fusion occurs...

During the growth and development of land plants, some specialized cells, such as tracheary elements, undergo secondary cell wall thickening. Secondary cell walls contain additional lignin, compared with primary cell walls, thus providing mechanical strength and potentially improving defenses against pathogens. However, the molecular mechanisms that initiate wall thickening are unknown. In this study, we identified an Arabidopsis thaliana leucine-rich repeat receptor-like kinase, encoded by AtVRLK1 (Vascular-Related RLK 1), that is specifically expressed in cells undergoing secondary cell wall thickening...

Receptor tyrosine kinase-like orphan receptor 1 (ROR1) is an oncoembryonic protein expressed on chronic lymphocytic leukemia (CLL) that can serve as a receptor for Wnt5a, which can promote leukemia-cell migration, proliferation, and survival. We found Wnt5a could induce ROR1 to complex with DOCK2 and induce activation of Rac1/2; these effects could be blocked by cirmtuzumab, a humanized anti-ROR1 mAb. We find that silencing DOCK2 specifically impaired the capacity of Wnt5a to induce activation of Rac1/2 or enhance CLL-cell proliferation...

BACKGROUND: Although transcription is the initial process of gene expression, posttranscriptional gene expression regulation has also played a critical role for fine-tuning gene expression in a fast, precise, and cost-effective manner. Although the regulation of sodium channel α-subunit ( SCN5A ) mRNA expression has been studied at both transcriptional and pre-mRNA splicing levels, the molecular mechanisms governing SCN5A mRNA expression are far from clear. METHODS AND RESULTS: Herein, we show that, as evidenced by ribonucleoprotein immunoprecipitation assay, RNA binding protein Hu antigen R/ELAV like RNA binding protein 1 (HuR/ELAVL1) and myocyte enhancer factor-2C (MEF2C) transcription factor mRNA are associated...
