This study presents the first report of purification of natterin-like protein (Nlp) in a non-venomous fish. The peptide identities of purified cod Nlp were confirmed through LC-MSMS and matched to a cod expressed sequence tag (EST). A partial cod nlp nucleotide sequence was amplified and sequenced based on this EST. Multiple sequence alignment of cod Nlp showed considerable homology with other teleost Nlps and the presence of an N-terminal jacalin-like lectin domain coupled with a C-terminal toxin domain. nlp expression was higher in skin, head kidney, liver and spleen than in other tissues studied...

Platelets are megakaryocyte-derived nuclear-free fragments that participate in cardiovascular diseases including acute myocardial infarction, ischemic stroke, hypertension, and atherosclerosis. At the endothelium damage site, platelets interact with sub-endothelial matrix proteins such as glycoprotein VI/Fc receptor γ-chain (GPVI/FcRγ), G protein-coupled receptor/phospholipase Cγ(β) (GPCR/PLCγ(β)), Rho/RhoK and integrin. The activation of these signaling pathways triggers intracellular calcium increase and causes platelet adhesion, aggregation, granule release and finally thrombus formation...

Zoledronic acid (ZOL) is a nitrogen-containing bisphosphonate used for the treatment of bone diseases and calcium metabolism. Anticancer activity of ZOL has been established, but its extraskeletal effects are limited due to its rapid uptake and accumulation to bone hydroxyapatite. In this work, we report on the development of tethered lipid bilayer-gated mesoporous silica nanocarriers (MSNs) for the incorporation, retention and intracellular delivery of ZOL. The in vitro anticancer activity of ZOL-loaded nanocarriers was evaluated by cell viability assay and live-cell imaging...

Extracellular matrix glycoprotein tenascin‑X (TNX) is the largest member of the tenascin family. In the present study, the contribution of TNX to liver dysfunction was investigated by administration of high‑fat and high‑cholesterol diet with high levels of phosphorus and calcium (HFCD) to wild‑type (WT) and TNX‑knockout (KO) mice. After 16 weeks of HFCD administration, the ratio of liver weight to body weight was approximately 22% higher in the HFCD‑fed WT mice compared with the HFCD‑fed TNX‑KO mice, indicating hepatomegaly in HFCD‑fed WT mice...

α-Ketoglutarate (α-KG), a pivotal metabolite in energy metabolism, has been implicated in nonalcoholic fatty liver disease (NAFLD) and several cancers. It is recently proposed that plasma α-KG is a surrogate biomarker of NAFLD. Here, we report the development of a novel "turn-on" chemosensor for α-KG that contains a coumarin moiety as a fluorophore. Using benzothiazole-coumarin (BTC) as inspiration, we designed a probe for calcium ion recognition that possesses a unique fluorophore compared with previously reported probes for α-KG measurement...

Protease-activated receptor 2 (PAR-2) plays an important role in the pathogenesis of liver fibrosis. We studied the effect of N1-3-methylbutyryl-N4-6-aminohexanoyl-piperazine (ENMD-1068), a PAR-2 antagonist, on the development of CCl4-induced liver fibrosis in mice and activation of hepatic stellate cells (HSCs) isolated from the mice. Before CCl4 injection, the mice were injected intraperitoneally with either 25 mg/kg or 50 mg/kg ENMD-1068 or with 200 μL of the vehicle control twice per week for 4 weeks...

The ability to generate potent immunotherapies locally and transiently for the treatment of cancers is a promising strategy to improve efficacy and decrease off-target toxicities. Here, we explored an alternative approach for the delivery of immunotherapeutic agents, in which we deliver the pDNA of an engineered PD-L1 trap and/or CXCL12 trap to the nucleus of liver hepatocytes via a lipid calcium phosphate nanoparticle. This strategy greatly increased the concentrations of immunotherapeutic agents in the local tissue, allowing the therapy to inhibit the accumulation of immune suppressive cells and liver metastasis...

Hepatitis B virus (HBV) is designated a "metabolovirus" due to the intimate connection between the virus and host metabolism. The nutrition state of the host plays a relevant role in the severity of HBV infection. Metabolic syndrome (MS) is prone to increasing HBV DNA loads and accelerating the progression of liver disease in patients with chronic hepatitis B (CHB). Cluster of differentiation 36 (CD36), also named fatty acid translocase, is known to facilitate long-chain fatty acid uptake and contribute to the development of MS...

Iron homeostasis relies on the amount of its absorption by the intestine and its release from storage sites, the macrophages. Iron homeostasis is also dependent on the amount of iron used for the erythropoiesis. Hepcidin, which is synthesized predominantly by the liver, is the main regulator of iron metabolism. Hepcidin reduces serum iron by inhibiting the iron exporter, ferroportin expressed both tissues, the intestine and the macrophages. In addition, in the enterocytes, hepcidin inhibits the iron influx by acting on the apical transporter, DMT1...

To investigate the effects of calcium propionate (CaP) supplementation on performance, the development of the internal organ, and gastrointestinal tract of calves at various stages of growth period, 54 male Jersey calves (age = 7 ± 1 d, body weight(BW) = 23.1 ± 1.2 kg) were randomly allocated to three treatment groups. While control calves were fed basis dietary with no additives (0CaP), other treatment calves were fed basis dietary supplementation with CaP at 50 (5CaP) or 100 (10CaP) g kg-1 dry matter. The experiment lasted 160 d and was divided into three feeding stages: Stage 1 (d 0 to 30), Stage 2 (d 31 to 90), and Stage 3 (d 91 to160)...

BACKGROUND: Postoperative hypophosphatemia is common and is associated with a lower risk of liver failure after hepatectomy but higher morbidity after pancreatectomy. Whether different physiologic mechanisms underlie the hypophosphatemia associated with these very different clinical outcomes is unclear. This study aims to evaluate the underlying mechanism in postoperative hypophosphatemia. STUDY DESIGNS: We prospectively enrolled 120 patients who underwent major hepatectomy (n=30), minor hepatectomy (n=30), pancreatectomy (n=30), and laparotomy without resection (control group, n=30)...

In recent years, there have been many reports about the efficacy of stenting for central bronchial stenosis. When central bronchial stenosis is due to metastasis of a malignant tumor to the trachea and/or bronchi (endobronchial metastasis: EM), it is classified as "narrow EM" and "broad EM." [1] We managed two patients in whom bilateral stent placement was required for narrow and broad EM arising from colorectal cancer. Case 1: In September 2011, a 66-year-old man underwent low anterior resection for advanced colorectal cancer associated with unresectable liver metastasis...
