This study aimed to evaluate whether salivary endocannabinoid (EC) and N-acylethanolamine (NAE) concentrations upon mastication of a semisolid food were involved in the sensory perception of fat taste, food liking and appetite in humans. A fat-enriched (FEP) and a low-fat control (CP) pudding were developed and used in a randomized cross-over study with 19 healthy volunteers. The study protocol combined a Modified Sham-Feeding (MSF) with a multiple-spoon Temporal Dominance of Sensations method. Subjects masticated and expectorated 10 spoons of the pudding and selected the dominant sensations among a list of attributes...

PURPOSE: Liver metastasis is the major and direct cause of death in patients with uveal melanoma (UM). There is no effective therapy for patients with metastatic UM. Improved treatments of hepatic metastatic patients with UM were urgently needed. Inspired by readily detectable key components in neddylation pathway in UM cells, we aimed at exploring whether neddylation pathway was a therapeutic target for liver metastatic UM. EXPERIMENTAL DESIGN: Expression of key proteins in neddylation pathway in UM was detected by Western blotting, real-time quantitative RT-PCR (qRT-PCR), and immunohistochemical staining...

NEDD8-activating enzyme (NAE) is an essential player of the NEDD8 conjugation pathway that regulates protein degradation. Meanwhile, drug repurposing is a cost-efficient strategy to identify new therapeutic uses for existing scaffolds. In this report, mitoxantrone (1) was repurposed as an inhibitor of NAE by virtual screening of an FDA-approved drug database. Compound 1 inhibited NAE activity in cell-free and cell-based systems with high selectivity and was competitive with ATP. Furthermore, compound 1 induced apoptosis of colorectal adenocarcinoma cancer cells through inhibiting the degradation of the neddylation substrate p53...

Alternate partial root-zone drip irrigation (ADI) or fertigation has favorable effect on crop water- and nitrogen- use efficiencies (WUE and NUE). However, the advantage of combined application of ADI and nitrogen fertigation on crop WUE and NUE remains unclear. A pot experiment was conducted to investigate the impact of three irrigation methods (CDI conventional drip irrigation (both halves of pot irrigated), ADI (both halves of pot alternatively irrigated) and FDI fixed partial root-zone drip irrigation (fixed half of pot irrigated)) and five nitrogen treatments (F0 no N supplied, F1-F4 0...

Using a laser-excited angle-resolved photoemission spectroscopy capable of bulk sensitive and high-energy resolution measurements, we reveal a new phenomenon of superconductors in the optimally doped trilayer Bi_{2}Sr_{2}Ca_{2}Cu_{3}O_{10+δ}. We observe a hybridization of the Bogoliubov bands derived from the inner and outer CuO_{2} planes with different magnitudes of energy gaps. Our data clearly exhibit the splitting of coherent peaks and the consequent enhancement of spectral gaps. These features are reproduced by model calculations, which indicate that the gap enhancement extends over a wide range of Fermi surface up to the antinode...

Context: Elevated urine net acid excretion (NAE), indicative of subclinical metabolic acidosis, has been associated with higher bone turnover. While NAE is the gold-standard clinical measure of acid-base status, it is impractical to measure in most clinical/research settings. Urine citrate, which is commonly measured, changes in response to acid-base status, but its association with bone turnover is uncertain. Objective: To evaluate the association between change in urine citrate and change in bone turnover and calcium excretion...

Excessive alcohol consumption leads to neurodegeneration, which contributes to cognitive decline that is associated with alcohol use disorders (AUDs). The endocannabinoid system has been implicated in the development of AUDs, but little is known about how the neurotoxic effects of alcohol impact the endocannabinoid system. Therefore, the current study investigated the effects of neurotoxic, binge-like alcohol exposure on components of the endocannabinoid system and related N-acylethanolamines (NAEs), and then evaluated the efficacy of fatty acid amide hydrolase (FAAH) inhibition on attenuating alcohol-induced neurodegeneration...

Diabetic encephalopathy (DE) is often a complication in patients with Alzheimer's disease due to high blood sugar induced by diabetic mellitus. Ergothioneine (EGT) and hispidin (HIP) are antioxidants present in Phellinus linteus. Methylglyoxal (MGO), a toxic precursor of advanced glycated end products (AGEs), is responsible for protein glycation. We investigated whether a combination EGT and HIP (EGT + HIP) protects against MGO-induced neuronal cell damage. Rat pheochromocytoma (PC12) cells were preincubated with EGT (2 μM), HIP (2 μM), or EGT + HIP, then challenged with MGO under high-glucose condition (30 μM MGO + 30 mM glucose; GLU + MGO) for 24-96 h...

Under salinity, Vitis spp. rootstocks can mediate salt (NaCl) exclusion from grafted V. vinifera scions enabling higher grapevine yields and production of superior wines with lower salt content. Until now, the genetic and mechanistic elements controlling sodium (Na+ ) exclusion in grapevine were unknown. Using a cross between two Vitis interspecific hybrid rootstocks, we mapped a dominant quantitative trait locus (QTL) associated with leaf Na+ exclusion (NaE) under salinity stress. The NaE locus encodes six high-affinity potassium transporters (HKT)...

MLN4924 inhibits the cullin-RING ligases mediated ubiquitin-proteasome system, and has showed antitumor activities in preclinical studies, but its effects and mechanisms on pancreatic cancer (PC) remains elusive. We found that MLN4924 inhibited the proliferation and clonogenicity of PC cells, caused DNA damage, particularly double-strand breaks, and leaded to Chk1 activation and cell-cycle arrest. Chk1 inhibitor SCH 900776 alone exhibited minimal cytotoxicity, and caused no DNA damage on PC cells. But in the combination therapy, SCH 900776 enhanced the cytotoxicity and DNA damage caused by MLN4924, likely by abrogating G2/M arrest and promoting DNA re-replication...

Wenhu Zhou, Juewen Liu
Nucleic acid enzymes (NAEs) are catalytically active RNA and DNA molecules. NAEs with RNA-cleaving activity are most extensively studied for applications in analytical chemistry, gene therapy and nanotechnology. Most NAEs require metal ions for activity. From a biochemical standpoint, these NAEs are reminiscent of metalloprotein enzymes with metal binding sites. While most NAEs require a single metal for the reaction, more and more recent examples have emerged that use two or even three metals for the reaction...

Protective mechanisms against drug-induced liver injury are actively being searched to identify new therapeutic targets. Among them, the anti-inflammatory N-acyl ethanolamide (NAE)-peroxisome proliferators activated receptor alpha (PPARα) system has gained much interest after the identification of its protective role in steatohepatitis and liver fibrosis. An overdose of paracetamol (APAP), a commonly used analgesic/antipyretic drug, causes hepatotoxicity, and it is being used as a liver model. In the present study, we have analyzed the impact of APAP on the liver NAE-PPARα system...
