Abstract Understanding genetic architecture of plasma lipidome could provide better insights into lipid metabolism and its link to cardiovascular diseases (CVDs). Here, we perform genome-wide association analyses 141 species (n = 2,181 individuals), followed by phenome-wide scans with 25 CVD related phenotypes 511,700 individuals). We identify 35 lipid-species-associated loci (P <5 ×10 −8 ), 10 which associate risk including five new loci- COL5A1 , GLTPD2 SPTLC3 MBOAT7 GALNT16 (false...
The cultural and ecological values of Pacific lamprey (Lampetra tridentata) have not been understood by Euro-Americans thus their great decline has almost gone unnoticed except Native Americans, who elevated the issue initiated research to restore its populations, at least in Columbia Basin. They regard as a highly valued resource result ksuyas (lamprey) become one icons. Ksuyas are harvested this day subsistence food various tribes along coast regarded for value. Interestingly, our review...
Abstract Unlike most anadromous fishes that have evolved strict homing behaviour, P acific lamprey ( E ntosphenus tridentatus ) seem to lack philopatry as evidenced by minimal population structure across the species range. Yet unexplained findings of within‐region genetic heterogeneity coupled with morphological and behavioural diversity described for suggest adaptive variation underlying fitness traits may be responsible. We employed restriction site–associated DNA sequencing genotype 4439...
Abstract Polygenic risk scores (PRS) for breast cancer have potential to improve prediction, but there is limited information on their utility in various clinical situations. Here we show that among 122,978 women the FinnGen study with 8401 cases, PRS modifies of two high-impact frameshift variants. Similarly, after diagnosis, individuals elevated an developing contralateral cancer, and can considerably assessment female first-degree relatives. In more detail, c.1592delT variant PALB2...
Corticosteroid hormones are critical for controlling metabolism, hydromineral balance, and the stress response in vertebrates. Although corticosteroid have been well characterized most vertebrate groups, identity of earliest hormone has remained elusive. Here we provide evidence that 11-deoxycortisol is lamprey, a member agnathans evolved more than 500 million years ago. We used RIA, HPLC, mass spectrometry analysis to determine active present lamprey plasma. also an receptor extracted from...
Despite significant investments in cancer research and drug discovery/development, the rate of new approval is ≤5% most cases metastatic remain incurable. Ninety-five percent drugs fail clinical development because a lack therapeutic efficacy and/or unacceptable toxicity. One major factors responsible for low success anticancer failure preclinical models to adequately recapitulate complexity heterogeneity human cancer. For throughput capacity reasons, high-throughput screening growth...
Summary 1. Spatial patterns in channel morphology and substratum composition at small (1–10 metres) large scales kilometres) were analysed to determine the influence of habitat heterogeneity on distribution abundance larval lamprey. 2. We used a nested sampling design multiple logistic regression evaluate spatial Pacific lamprey, Lampetra tridentata , 30 sites (each composed twelve 1‐m 2 quadrat samples) distributed throughout 55‐km section Middle Fork John Day River, OR, U.SA.

Patients with clinical manifestations of leishmaniasis, including cutaneous have limited treatment options, and existing therapies frequently significant untoward liabilities. Rapid expansion in the diversity available leishmanicidal chemotypes is initial step finding alternative efficacious treatments. To this end, we combined a low-stringency Leishmania major promastigote growth inhibition assay structural computational filtering algorithm. After rigorous validation process, interrogated...
Cutaneous leishmaniasis remains ignored in therapeutic drug discovery programs worldwide. This is mainly because cutaneous frequently a disease of impoverished populations countries where funds are limited for research and patient care. However, the health burden individuals endemic areas mandates readily available, effective, safe treatments. Of existing therapeutics, many growth inhibitory to Leishmania parasites, potentially creating dormant parasite reservoirs that can be activated when...
Glucocorticoids (GCs) are produced by the adrenal glands and circulate in blood to coordinate organismal physiology. In addition, different tissues may independently regulate their local GC levels via synthesis. Here, we find that mouse, endogenous GCs show tissue-specific developmental patterns, rather than mirroring blood. Using solid-phase extraction, HPLC, specific immunoassays, quantified steroids found of female male mice, (1) can be much higher systemic levels, (2) follow age-related...
Studies have demonstrated ways in which climate-related shifts the distributions and relative abundances of marine species are expected to alter dynamics catch potential global fisheries. While these studies assess impacts on large-scale commercial fisheries, few efforts been made quantitatively project small-scale subsistence fisheries that economically, socially culturally important many coastal communities. This study uses a dynamic bioclimate envelope model scenarios changes abundance,...
In solid tumors like head and neck cancer (HNC), chronic acute hypoxia have serious adverse clinical consequences including poorer overall patient prognosis, enhanced metastasis, increased genomic instability, resistance to radiation-, chemo-, or immuno-therapies. However, cells in the two-dimensional monolayer cultures typically used for drug discovery experience 20%-21% O2 levels (normoxic) which are 4-fold higher than normal tissues ≥10-fold hypoxic regions of tumors. The oxygen...
Background The parasitic protozoan Trypanosoma brucei utilizes glycolysis exclusively for ATP production during infection of the mammalian host. first step in this metabolic pathway is mediated by hexokinase (TbHK), an enzyme essential to parasite that transfers γ-phospho a hexose. Here we describe identification and confirmation novel small molecule inhibitors bacterially expressed TbHK1, one two TbHKs T. brucei, using high throughput screening assay. Methodology/Principal Findings...
Pacific lamprey, Lampetra tridentata , has declined precipitously throughout their range in the Columbia River basin of North America. Tribal Nations and Federal State agencies are engaged efforts to restore these fish. Understanding whether lamprey emit detect migratory pheromones is particularly important for restoration efforts. Using behavioural assays, we demonstrated that adult attracted odors emanating from larval conspecifics. We then identified putative released by lamprey. Chemical...
Multicellular tumor spheroid (MCTS) cultures represent more physiologically relevant in vitro cell models that recapitulate the microenvironments and cell–cell or cell–extracellular matrix interactions which occur solid tumors. We characterized morphologies, viability, growth behaviors of MCTSs produced by 11 different head neck squamous carcinoma (HNSCC) lines seeded into cultured ultra-low attachment microtiter plates (ULA-plates) over extended periods time. HNSCC MCTS developed...
