Background In beef cattle, more than 50% of the energy input to produce a unit of beef is consumed by the female that produced the calf. Development of genomic tools to identify females with high genetic merit for reproductive function could increase the profitability and sustainability of beef *** Genome-wide association studies(GWAS) were performed using a single-step genomic best linear unbiased prediction approach on pregnancy outcome traits from a population of Angus–Brahman crossbred heifers. Furthermore, a validation GWAS was performed using data from another farm. Heifers were genotyped with the Bovine GGP F250 array that contains 221,077 SNPs. In the discovery population, heifers were bred in winter breeding seasons involving a single round of timed artificial insemination(AI) followed by natural mating for 3 months. Two phenotypes were analyzed: pregnancy outcome to first-service AI(PAI;n = 1,481) and pregnancy status at the end of the breeding season(PeBS;n = 1,725). The heritability was estimated as 0.149 and 0.122 for PAI and PeBS, respectively. In the PAI model, one quantitative trait locus(QTL), located between 52.3 and 52.5 Mb on BTA7, explained about 3% of the genetic variation, in a region containing a cluster of γ-protocadherin genes and SLC25A2. Other QTLs explaining between 0.5% and 1% of the genetic variation were found on BTA12 and 25. In the PeBS model, a large QTL on BTA7 was synonymous with the QTL for PAI, with minor QTLs located on BTA5, 9, 10, 11, 19, and 20. The validation population for pregnancy status at the end of the breeding season were Angus–Brahman crossbred heifers bred by natural mating. In concordance with the discovery population, the large QTL on BTA7 and QTLs on BTA10 and 12 were *** In summary, QTLs and candidate SNPs identified were associated with pregnancy outcomes in beef heifers, including a large QTL associated with a group of protocadherin genes. Confirmation of these associations

Toxicity of a seafood toxin， domoic acid， in the retina via modulation of the NRF2 and NF-κB pathways

Food Science and Human Wellness 2024年

作者： gabriel.Mbuta Tchivelekete Yanqun Cao Mohammad Almarhoun Xinzhi Zhou Agostinho Francisco Cachapa Sebasti?o Tumitangua James Reilly Patricia e.Martin Xinhua Shu Department of Biological and Biomedical Sciences， Glasgow Caledonian University Department of Marine Biology， Faculty of Natural Science， University of Namibe Puai Medical School， Shaoyang University Department of Vision Science， Glasgow Caledonian University

Domoic acid (DA)， a biotoxin， is produced by several species of marine dinoflagellate and diatom during harmful algal bloom events. DA is a neurotoxin， in humans and non-human primates， oral exposure to DA results in gastrointestinal effects， while DA at higher doses leads to neurological symptoms， seizures and memory deficiency. exposure of humans to DA occurs mainly through consumption of contaminated seafoods containing an accumulation of the toxin. Previously， it was unclear if DA can have toxic effects on the retina. We assessed the toxicity of DA in human retinal cells (ARPe-19) and in zebrafish embryos. DA significantly lowered ARPe-19 cell viability dose-dependently， and decreased anti-oxidative capacity， increased inflammation， and promoted cell death， possibly through modulating the NRF2 and NF-κB signalling pathways. Zebrafish embryos exposed to DA for four days from one day post fertilization (dpf) had an increase in mortality and a decrease in both hatching and heartbeat rate and exhibited morphological abnormalities. DA treatment also significantly downregulated expression of antioxidant genes and upregulated expression of inflammation mediators， as well as causing photoreceptor death in zebrafish embryos. The results demonstrate that consuming seafood containing DA will have potential toxic effects in human retinas.

Germline activating variants in WWP1,which encodes an e3 ubiquitin ligase that antagonizes PTeN tumor suppressive function,have been proposed as an alternative mechanism of PTeN inactivation in PTeN-hamartoma-tumor syndrome(PHTS)-like patients with wildtype PTeN.1 More specifically,heterozygous,potentially activating wwP1 variants were first identified by Lee et al in patients affected with gastrointestinal oligopolyposis,including adenomatous,hyperplastic/serrated,and hamartomatous polyps,and occasionally with colorectal cancer(Table 1).Subsequently,based on the PHTS phenotypic features,wWP1 mutational screening was performed in patients with thyroid nodules,2 or normocephalic autism spectrum disorder(ASD),3 where germline WWP1 variants were also identified(Table S1).
