Chinese wolfberry (Lycium spp.) is an important edible and medicinal plant, with a long cultivation history. The genetic relationships among wild Lycium species and landraces have been unclear for a number of reasons, which has hindered the breeding of modern Chinese wolfberry cultivars. In this study, we collected 19 accessions of Chinese wolfberry germplasm, and constructed the genetic relationship based on RAD-seq markers. We obtained 30.32 Gb of clean data, with the average value of each sample being 1...

With the pandemic of type 2 diabetes (T2D), there is an ever-increasing need to fully understand the underlying mechanisms of the disease. Type 2 diabetes shows a high heritability risk (25-80%); however, genes account only for 10% of this risk. From all the risk factors for diabetes, epigenetic mechanisms have the highest statistical scoring in explaining the disease. A multitude of organ-specific epigenomic changes have been linked to type 2 diabetes. Nutritional influences, mainly in the early life, physical activity level, environmental toxins act as epigenetic factors and the recognized epigenetic changes can represent a therapeutical target, new drugs being currently in development for this application...

Growth traits are complex quantitative traits controlled by numerous candidate genes, and they can be well-evaluated using body measurement traits. As the members of the nicotinamide adenine dinucleotide-dependent family of histone deacetylases, class I sirtuin genes (including SIRT1, SIRT2 and SIRT3) play crucial roles in regulating lipid metabolism, cellular growth and metabolism, suggesting that they are potential candidate genes affecting body measurement traits in animals. Hence, the objective of this work aimed to detect novel insertions/deletions (indels) of SIRT1, SIRT2 and SIRT3 genes in 955 cattle belonging to five breeds, as well as to evaluate their effects on body measurement traits...

Imprinted genes are characterized by monoallelic expression that is dependent on parental origin. Comparative analysis of imprinted genes between species is a powerful tool for understanding the biological significance of genomic imprinting. The slc38a4 gene encodes a neutral amino acid transporter and is identified as imprinted in mice. In this study, the imprinting status of SLC38A4 was assessed in bovine adult tissues and placenta using a polymorphism-based approach. Results indicate that SLC38A4 is not imprinted in eight adult bovine tissues including heart, liver, spleen, lung, kidney, muscle, fat, and brain...

The Ruddy-breasted Crake (Porzana fusca) is an extremely poorly known species. Although it is not listed as globally endangered, in recent years, with the interference of climate change and human activities, its habitat is rapidly disappearing and its populations have been shrinking. There are two different life history traits for Ruddy-breasted Crake in China, i.e., non-migratory population in the south and migratory population in the north of China. In this study, mitochondrial control sequences and microsatellite datasets of 88 individuals sampled from 8 sites were applied to analyze their genetic diversity, genetic differentiation, and genetic structure...

With longevity, the prevalence of osteoporosis, which occurs when the activity of osteoclast surpasses that of osteoblasts, has increased in dogs. However, limited information is available on canine osteoclastogenesis. We herein described culture conditions to induce osteoclasts from canine bone marrow cells, and identified factors affecting canine osteoclastogenesis. Tartrate-resistant acid phosphatase-positive multinucleated cells were efficiently formed in a culture of bone marrow mononuclear cells with macrophage colony-stimulating factor (M-CSF 25 ng/mL) for 3 days and a subsequent culture in the presence of M-CSF (25 ng/mL) and soluble receptor activator of NF-κB ligand (RANKL 50 ng/mL) for 4 days...

Treatment with tetrahydrobiopterin (BH4) is the latest therapeutic option approved for patients with phenylketonuria (PKU)-one of the most frequent inborn metabolic diseases. PKU or phenylalanine hydroxylase (PAH) deficiency is caused by mutations in the PAH gene. Given that some PAH mutations are responsive to BH4 treatment while others are non-responsive, for every novel mutation that is discovered it is essential to confirm its pathogenic effect and to assess its responsiveness to a BH4 treatment in vitro, before the drug is administered to patients...

Lupus nephritis (LN) is a major cause of morbidity and mortality in systemic lupus erythematosus (SLE). Previous studies suggest that mutant A20 binding inhibitor of NF-κB 1 (ABIN1) protein encoded by tumor necrosis factor alpha-induced protein 3 interacting protein 1 (TNIP1) gene is associated with LN via NF-κB dysregulation. The aim of the current study was to evaluate the association of TNIP1 gene SNP rs7708392 with SLE and LN in Egyptian patients. 5' nuclease Allelic discrimination was used to evaluate the frequency of TNIP1 SNP rs7708392 in 53 patients with LN, 57 SLE patients without nephritis and 85 healthy controls...

The inducible repair enzyme O6 -methylguanine-DNA methyltransferase (MGMT) eliminates O6 -methylguanine adducts in DNA and protects the cells from damaging effects of alkylating agents. We have found that anti-MGMT antibodies recognize both the MGMT protein with a mol. weight ~ 24 kDa and a protein with a mol. weight ~ 48 kDa, which was named MARP (anti-methyltransferase antibody recognizable protein). A number of growth factors and cytokines were shown to regulate the expression of MGMT and MARP proteins...
