ABSTRACT
Synthetic cannabinoids are a group of novel psychoactive substances with similar properties to Δ9-THC. Among the vast number of synthetic cannabinoids, designed to be tested in clinical trials, JWH-018 was the first novel psychoactive substance found in the recreational drug marketplace. The consumption of JWH-018 shows typical effects of CB1 agonists including sedation, cognitive dysfunction, tachycardia, postural hypotension, dry mouth, ataxia and psychotropic effects, but appeared to be more potent than Δ9-THC. However, studies on human cells have shown that JWH-018 toxicity depends on the cellular line used. Despite these studies, the underlying molecular mechanisms to JWH-018 action has not been clarified yet. To understand the impact of JWH-018 at molecular and cellular level, we used Saccharomyces cerevisiae as a model. The results showed an increase in yeast growth rate in the presence of this synthetic cannabinoid due to an enhancement in the glycolytic flux at expense of a decrease in pentose phosphate pathway, judging by 2D-Gel proteomic analysis, qRT-PCR experiments and ATP measurements. Overall, our results provide insights into molecular mechanisms of JWH-018 action, also indicating that Saccharomyces cerevisiae is a good model to study synthetic cannabinoids.

AbstractHumans carry a much larger percentage of body fat than other primates. Despite the central role of adipose tissue in metabolism, little is known about the evolution of white adipose tissue in primates. Phenotypic divergence is often caused by genetic divergence in cis-regulatory regions. We examined the cis-regulatory landscape of fat during human origins by performing comparative analyses of chromatin accessibility in human and chimpanzee adipose tissue using rhesus macaque as an outgroup. We find that many regions that have decreased accessibility in humans are enriched for promoter and enhancer sequences, are depleted for signatures of negative selection, are located near genes involved with lipid metabolism, and contain a short sequence motif involved in the beigeing of fat, the process in which lipid-storing white adipocytes are transdifferentiated into thermogenic beige adipocytes. The collective closing of many putative regulatory regions associated with beigeing of fat suggests a mechanism that increases body fat in humans.

AbstractYWHAE gene product belongs to the 14-3-3 protein family that mediates signal transduction in plants and mammals. Protein-coding and non-coding RNA (lncRNA) transcripts have been reported for this gene in human. Here, we aimed to functionally characterize YWHAE-encoded lncRNA in colorectal cancer-originated cells. RNA-seq analysis showed that YWHAE gene is upregulated in colorectal cancer specimens. Additionally, bioinformatics analysis suggested that YWHAE lncRNA sponges miR-323a-3p and miR-532-5p that were predicted to target K-Ras 3′UTR sequence. Overexpression of YWHAE lncRNA resulted in upregulation of K-Ras gene expression, while overexpression of both miR-323a-3p and miR-532-5p had an inverse effect, detected by RT-qPCR. Consistently, western blot analysis confirmed that YWHAE lncRNA overexpression upregulated K-Ras/Erk1/2 and PI3K/Akt signaling pathways, while miR-323a-3p and miR-532-5p overexpression suppressed both pathways in HCT116 cells. Furthermore, dual luciferase assay validated the direct interaction of miR-323a-3p and miR-532-5p with K-Ras 3′UTR sequence and supported the sponging effect of YWHAE lncRNA over both miRNAs. These results suggested YWHAE lncRNA as an oncogene that exerts its effect through sponging miR-323a-3p and miR-532-5p and in turn, upregulates K-Ras/Erk1/2 and PI3K/Akt signaling pathways. Consistently, flow cytometry analysis, MTT assay and measuring cyclin D1 gene expression, confirmed the cell cycle stimulatory effect of YWHAE lncRNA, while miR-323a-3p and miR-532-5p showed an inhibitory effect on cell cycle progression. Finally, wound-healing assay supported the cell migratory effect of YWHAE lncRNA in HCT116 cells. This study identified a novel mechanism involving YWHAE-encoded lncRNA, miR-323a-3p and miR-532-5p in regulating HCT116 cell survival and suggested a potential therapeutic avenue for colorectal cancer.

Abstract
Cost-effective and feasible production system of meat goats requires that grazed forages are converted to profitable goat meat product. However, there are studies as how altering forage type influences ruminal fermentation parameters and animal growth performance, and interact with microbiota in meat goats. Our objective for current study was to examine whether the comparative abundance of the Bacteroidetes (B) and Firmicutes (F) bacterial phyla in meat goats fed simple and mixed forages influenced average daily gain (ADG) and rumen fermentation parameters. In the present study, a molecular approach, bacterial tag-encoded FLX amplicon pyrosequencing (bTEFAP) was applied to accomplish diversity analyses of rumen bacterial populations. Thirty-six Kiko-cross growing meat goats (body weight (BW) = 27.7 ± 2.83 kg) at approximately 7 mo of age were used in this study. Animals were randomly allocated to 3 pasture treatment groups (n = 12) as follows: 1) bermudagrass pasture (BG; Cynodon dactylon), 2) sunn hemp forage (SH; Crotalaria juncea), and 3) BG + SH forage combinations. There were 2 replicates per treatment and animals grazed these pastures for 45 d. Results indicated that treatments had similar initial BW, but final BW and ADG were higher (P < 0.01) for SH and BG + SH combinations than for BG alone. Animal ADG and rumen fermentation (acetate to propionate; A/P ratios) were highly correlated with the abundance of various bacterial populations within the rumen microbiome. There were linear decreases in percentage of Bacteroidetes (R2 = −0.84; P < 0.05) associated with decreasing ADG. In contrast, increased ADG was linearly associated with higher percentages of Firmicutes (R2 = 0.79; P < 0.05), F/B ratios (R2 = 0.88; P = 0.07), total VFA (R2 = 0.45; P < 0.05), and lower A/P ratio (R2 = −0.72; P < 0.01). This suggests that the substrates (diets) and bacterial community have the role in adapting host biological parameters in meat goats. The abundance examination of both Bacteroidetes and Firmicutes will be useful for exploring the structure of gut microbiota as an estimate of animal performance.

Published: June 2019

AbstractEther glycerolipids, plasmalogens are found in various mammalian cells and tissues. However, physiological role of plasmalogens in epithelial cells remains unknown. We herein show that synthesis of ethanolamine-containing plasmalogens, plasmenylethanolamine (PlsEtn), is deficient in MCF7 cells, an epithelial cell line, with severely reduced expression of alkyl-dihydroxyacetonephosphate synthase (ADAPS), the second enzyme in the PlsEtn biosynthesis. Moreover, expression of ADAPS or supplementation of PlsEtn containing C18-alkenyl residue delays the migration of MCF7 cells as compared to that mock-treated MCF7 and C16-alkenyl-PlsEtn-supplemented MCF7 cells. Localization of E-cadherin to cell–cell junctions is highly augmented in cells containing C18-alkenyl-PlsEtn. Together, these results suggest that PlsEtn containing C18-alkenyl residue plays a distinct role in the integrity of E-cadherin-mediated adherens junction.
Consideration of sample source for establishing reliable genetic microsatellite data from mammalian carnivore specimens held in natural history collections

Published: June 2019

AbstractSpecimens from natural history collections (NHCs) are increasingly being used for genetic studies and can provide information on extinct populations, facilitate comparisons of historical and contemporary populations, produce baseline data before environmental changes, and elucidate patterns of change. Destructive sampling for DNA may be in disagreement with NHC goals of long-term care and maintenance. Differentiating quality among sample sources can direct destructive sampling to the source predicted to yield the highest quality DNA and most reliable data, potentially reducing damage to specimens, laboratory costs, and genotyping errors. We used the kit fox (Vulpes macrotis) as a model species and evaluated the quality and reliability of genetic data obtained from carnivoran specimens via three different sample sources: cranial bones, nasal bones, and toepads. We quantified variation in microsatellite amplification success and genotyping error rates and assessed the reliability of source-specific genic data. Toepads had the highest amplification success rates and lowest genotyping error rates. Shorter loci had higher amplification success and lower allelic dropout rates than longer loci. There were substantial differences in the reliability of resulting multilocus genotypes. Toepads produced the most reliable data, required the fewest replicates, and therefore, had the lowest costs to achieve reliable data. Our results demonstrate that the quality of DNA obtained from specimens varies by sample source and can inform NHCs when evaluating requests for destructive sampling. Our results suggest that prior to large-scale specimen sampling, researchers should conduct pilot studies to differentiate among source-specific data reliability, identify high performing loci, reduce costs of analyses, and minimize destructive sampling.

AbstractProgressive supranuclear palsy with predominant cerebellar ataxia (PSP-C) has been reported as a rare clinical subtype, but the underlying pathology of its cerebellar ataxia remains unclear. Here, we report a patient with the coexistence of PSP with pontocerebellar atrophy and myotonic dystrophy type 1 (DM1). A 73-year-old man who was an asymptomatic carrier of DM1 (66 CTG repeats) started developing ataxic gait with multiple falls, visual blurring, double vision, and word finding difficulty at age 62 and was initially diagnosed with multiple system atrophy (MSA). Subsequently, the diagnosis was changed to PSP due to hypometric downward gaze, reduced blink frequency, symmetric bradykinesia, rigidity, and the absence of autonomic dysfunction. He eventually developed delayed grip opening with percussion myotonia at age 72. At autopsy, severe neuronal degeneration and astrogliosis in the pontocerebellar structures suggested MSA, but immunohistochemistry for α-synuclein did not reveal neuronal or glial cytoplasmic inclusions. Immunohistochemistry for phospho-tau and 4-repeat tau confirmed a neuropathological diagnosis of PSP with exceptionally numerous coiled bodies and threads in the pontine base and cerebellar white matter. This unusual distribution of 4-repeat tau pathology and neuronal degeneration with astrogliosis is a plausible clinicopathological substrate of PSP-C.
Distribution and possible biosynthetic pathway of non-protein sulfur amino acids in legumes

Published: June 2019

Abstract
Some grain legumes store sulfur in the form of non-protein amino acids in seed. γ-Glutamyl-S-methylcysteine is found in Phaseolus and several Vigna species. γ-Glutamyl-S-ethenylcysteine, an antinutritional compound, is present in Vicia narbonensis. In P. vulgaris, free S-methylcysteine levels are higher at early stages of seed development followed by a decline. γ-Glutamyl-S-methylcysteine accumulates later, in two phases, with a lag during reserve accumulation. The concentration of total S-methylcysteine, quantified after acid hydrolysis, is positively regulated by sulfate nutrition. The levels of both γ-glutamyl-S-methylcysteine and γ-glutamyl-S-ethenylcysteine are modulated in response to changes in seed protein composition. A model is proposed whereby the majority of γ-glutamyl-S-methylcysteine in P. vulgaris is synthesized via the intermediate S-methylhomoglutathione. Knowledge of the biosynthesis of non-protein sulfur amino acids is required for metabolic engineering approaches, in conjunction with manipulation of the protein sink, to increase the concentration of nutritionally essential methionine and cysteine. This would improve protein quality of some important legume crops.

AbstractMaintaining mitochondrial proteome integrity is especially important under stress conditions to ensure a continued ATP supply for protection and adaptation responses in plants. Deg/HtrA proteases are important factors in the cellular protein quality control system, but little is known about their function in mitochondria. Here we analyzed the expression pattern and physiological function of Arabidopsis thaliana DEG10, which has homologs in all photosynthetic eukaryotes. Both expression of DEG10:GFP fusion proteins and immunoblotting after cell fractionation showed an unambiguous subcellular localization exclusively in mitochondria. DEG10 promoter:GUS fusion constructs showed that DEG10 is expressed in trichomes but also in the vascular tissue of roots and aboveground organs. DEG10 loss-of-function mutants were impaired in root elongation, especially at elevated temperature. Quantitative proteome analysis revealed concomitant changes in the abundance of mitochondrial respiratory chain components and assembly factors, which partially appeared to depend on altered mitochondrial retrograde signaling. Under field conditions, lack of DEG10 caused a decrease in seed production. Taken together, our findings demonstrate that DEG10 affects mitochondrial proteostasis, is required for optimal root development and seed set under challenging environmental conditions, and thus contributes to stress tolerance of plants.

Published: June 2019

Abstract

Introduction
Since inception of robotic-assisted surgery (RAS) in 1999, there has been an exponential rise in RAS in both number and complexity of surgical cases performed. The majority of these cases are gynecologic surgery in nature, with only a quarter of them labeled as general surgery. The purpose of this study is to determine if RAS in the Department of Defense (DoD) mirrors these trends.

Methods
A total of 6,204 RAS cases from across the DoD were reviewed between 01 January 2015 and 30 September 2017 from every Military Treatment Facility (MTF) that employs a robotic surgical device (various models of the da Vinci robotic surgical system by Intuitive Surgical). Specialty, number, and surgeon were recorded for each case. These end points were also examined for trends overtime and compared to similar civilian data.

Results
The number of MTFs performing robotic surgery and the number of cases performed increased significantly. An average of 373 cases per quarter-year were performed in 2015, 647 in 2016, and 708 in 2017. The number of RAS cases increased by about 10% every quarter-year during this time period. RAS was most commonly performed by general surgery in 10 of the 14 MTFs examined.

Conclusions
MTFs implemented RAS much later than the civilian world. However, since its implementation, the frequency of RAS use has increased at a faster rate in the DoD than in the civilian world. Possible reasons for this are a younger pool of surgeons in the military and less demands on cost-effective productivity, allowing these younger surgeons to focus on emerging technology rather than maximizing surgical cost efficiency. General surgery constitutes the majority of RAS cases in the DoD. It is unclear why this difference from the civilian world exists.
Measurement of DNA damage with the comet assay in high-prevalence diseases: current status and future directions
Authors: Møller Peter , Stopper Helga , Collins Andrew R 
Published: June 2019

Abstract
The comet assay is widely used in studies on genotoxicity testing, human biomonitoring and clinical studies. The simple version of the assay detects a mixture of DNA strand breaks and alkali-labile sites; these lesions are typically described as DNA strand breaks to distinguish them from oxidatively damaged DNA that are measured with the enzyme-modified comet assay. This review assesses the association between high-prevalence diseases in high-income countries and DNA damage measured with the comet assay in humans. The majority of case–control studies have assessed genotoxicity in white blood cells. Patients with coronary artery disease, diabetes, kidney disease, chronic obstructive pulmonary disease and Alzheimer’s disease have on average 2-fold higher levels of DNA strand breaks compared with healthy controls. Patients with coronary artery disease, diabetes, kidney disease and chronic obstructive pulmonary disease also have 2- to 3-fold higher levels of oxidatively damaged DNA in white blood cells than controls, although there is not a clear difference in DNA damage levels between the different diseases. Case–control studies have shown elevated levels of DNA strand breaks in patients with breast cancer, whereas there are only few studies on colorectal and lung cancers. At present, it is not possible to assess if these neoplastic diseases are associated with a different level of DNA damage compared with non-neoplastic diseases.

Abstract

Background
Fluid overload is frequent among hemodialysis (HD) patients. Dialysis therapy itself may favor sodium imbalance from sodium dialysate prescription. As on-line hemodiafiltration (OL-HDF) requires large amounts of dialysate infusion, this technique can expose to fluid accumulation in case of a positive sodium gradient between dialysate and plasma. To evaluate this risk, we have analyzed and compared the fluid status of patients treated with HD or OL-HDF in French NephroCare centers.

Method
This is a cross-sectional and retrospective analysis of prevalent dialysis patients. Data were extracted from the EUCLID5 data base. Patients were split in 2 groups (HD and OL-HDF) and compared as whole group or matched patients for fluid status criteria including predialysis relative fluid overload (RelFO%) status from the BCM®.

Results
2242 patients (age 71 years; female: 39%; vintage: 38 months; Charlson index: 6) were studied. 58% of the cohort were prescribed post-dilution OL-HDF. Comparing the HD and OL-HDF groups, there was no difference between HD and OL-HDF patients regarding the predialysis systolic BP, the interdialytic weight gain, the dialysate-plasma sodium gradient, and the predialysis RelFO%. The stepwise logistic regression did not find dialysis modality (HD or OL-HDF) associated with fluid overload or high predialysis systolic blood pressure. In OL-HDF patients, monthly average convective or weekly infusion volumes per session were not related with the presence of fluid overload.

Conclusions
In this cross-sectional study we did not find association between the use of post-dilution OL-HDF and markers of fluid volume excess. Aligned dialysis fluid sodium concentrations to patient predialysis plasma sodium and regular monitoring of fluid volume status by bioimpedance spectroscopy may have been helpful to manage adequately the fluid status in both OL-HDF and HD patients.

ABSTRACT
The permanent human settlement of the Tibetan Plateau (TP) has been suggested to have been facilitated by the introduction of barley agriculture ∼3.6 kilo-years ago (ka). However, how barley agriculture spread onto the TP remains unknown. Given that the lower altitudes in the northeastern TP were occupied by millet cultivators from 5.2 ka, who also adopted barley farming ∼4 ka, it is highly possible that it was millet farmers who brought barley agriculture onto the TP ∼3.6 ka. To test this hypothesis, we analyzed mitochondrial DNA (mtDNA) from 8277 Tibetans and 58 514 individuals from surrounding populations, including 682 newly sequenced whole mitogenomes. Multiple lines of evidence, together with radiocarbon dating of cereal remains at different elevations, supports the scenario that two haplogroups (M9a1a1c1b1a and A11a1a), which are common in contemporary Tibetans (20.9%) and were probably even more common (40–50%) in early Tibetans prior to historical immigrations to the TP, represent the genetic legacy of the Neolithic millet farmers. Both haplogroups originated in northern China between 10.0–6.0 ka and differentiated in the ancestors of modern Tibetans ∼5.2–4.0 ka, matching the dispersal history of millet farming. By showing that substantial genetic components in contemporary Tibetans can trace their ancestry back to the Neolithic millet farmers, our study reveals that millet farmers adopted and brought barley agriculture to the TP ∼3.6–3.3 ka, and made an important contribution to the Tibetan gene pool.
