Protein tyrosine sulfation (PTS) is a widespread posttranslational modification that induces intercellular and extracellular responses by regulating protein-protein interactions and enzymes activities. Although PTS affects numerous physiological and pathological processes, only a small fraction of the total predicted sulfated proteins has been identified to date. Here, we localized the potential sulfation sites of Escherichia coli proteins on a proteome microarray by using a 3'-phosphoadenosine 5'-phosphosulfate (PAPS) synthase-coupled tyrosylprotein sulfotransferase (TPST) catalysis system that involves in situ PAPS generation and TPST catalysis...

BACKGROUND: Bone contusions are frequently encountered in magnetic resonance imaging (MRI) evaluation of knee anterior cruciate ligament (ACL) injuries. Their role as indicators of injury severity remains unclear, primarily due to indeterminate levels of joint injury forces and to a lack of preinjury imaging. PURPOSE: The purpose of this study was to 1) quantify bone contusion pathogenesis following traumatic joint injuries using fixed imaging follow-ups, and 2) assess the feasibility of using longitudinal bone contusion volumes as an indicator of knee injury severity...

In a previous study, miR-2478 was demonstrated to be up-regulated in dairy goat mammary glands during peak lactation compared with the dry period. However, the detailed mechanisms by which miR-2478 regulates physiological lactation and mammary gland development in dairy goats remain unclear. In this study, we used bioinformatics analysis and homologous cloning to predict the target genes of miR-2478 and selected INSR, FBXO11, TGFβ1 and ING4 as candidate target genes of miR-2478. Subsequently, by targeting the 5'UTR of the TGFβ1 gene, we verified that miR-2478 significantly inhibited TGFβ1 transcription and the Pearson's correlation coefficient between miR-2478 expression and TGFβ1 expression was -0...

Frutalin is a galactose-binding lectin that has an irreversible cytotoxic effect on HeLa cervical cancer cells, by inducing apoptosis and inhibiting cell proliferation. It was previously shown that after in vitro incubation, frutalin is internalized into HeLa cells nucleus, which indicates that frutalin apoptosis-inducing activity might be linked with its nuclear localization. Considering that drugs commonly used for cancer treatment have a deleterious effect on germ cells, the aim of this study was to evaluate the effect of frutalin on the activation, survival, ultrastructure and gene expression in follicles cultured within ovarian tissue...

BACKGROUND: Long noncoding RNAs (lncRNAs) are involved in regulating animal development, however, their function in the onset of puberty in goats remain largely unexplored. To identify the genes controlling the regulation of puberty in goats, we measured lncRNA and mRNA expression levels from the hypothalamus. RESULTS: We applied RNA sequencing analysis to examine the hypothalamus of pubertal (case; n = 3) and prepubertal (control; n = 3) goats. Our results showed 2943 predicted lncRNAs, including 2012 differentially expressed lncRNAs, which corresponded to 5412 target genes...

α-lactalbumin is a protein of dual function found in milk of most mammals. α-lactalbumin binds β-1,4-galactosyltransferase to form the regulatory subunit for lactose synthesis and has also been shown to cause cell death. This study shows, for the first time, that α-lactalbumin isolated in a rare 28kDa dimeric form induces cell death, while 14kDa monomeric α-lactalbumin is inactive. In contrast to the casein derived and chemically induced α-lactalbumin variants, MAL and HAMLET/BAMLET, the effects of 28kDa α-lactalbumin are calcium independent and, unlike MAL and HAMLET, 28kDa α-lactalbumin dimer causes cell death of primary mammary cells and a variety of immortalised cell lines, which are committed to cell death pathways within 1-4h of exposure...

BACKGROUND: Traditional approaches for generating goat pluripotent stem cells (iPSCs) suffer from complexity and low preparation efficiency. Therefore, we tried to derive goat iPSCs with a new method by transfecting exogenous Oct4, Sox2, Klf4 and c-Myc mRNAs into goat embryonic fibroblasts (GEFs), and explore the mechanisms regarding the transcription regulation of the reprogramming factors in goat iPSCs induction. RESULTS: mRNAs of the four reprogramming factors were transfected into GEFs, and were localized in nucleus with approximately 90% transfection efficiency...

Mineral requirements of pregnant dairy goats are still not well defined; therefore, we investigated the net Ca, P, Mg, Na and K requirements for pregnancy and for maintenance during pregnancy in two separate experiments. Experiment 1 was performed to estimate the net Ca, P, Mg, Na and K requirements in goats carrying single or twin fetuses from 50 to 140 days of pregnancy (DOP). The net mineral requirements for pregnancy were determined by measuring mineral deposition in gravid uterus and mammary gland after comparative slaughter...

This research identifies favorable areas for goat production systems in the state of Veracruz, Mexico. Through the use of the analytic hierarchy process, layers of biophysical and soil information were combined to generate a model of favorability. Model validation was performed by calculating the area under the curve, the true skill statistic, and a qualitative comparison with census records. The results showed the existence of regions with high (4494.3 km(2)) and moderate (2985.8 km(2)) favorability, and these areas correspond to 6...

Finding a valid antibody to detect mouse programmed death ligand 1 (PDL-1) by immunohistochemistry or immunofluorescence staining has been notoriously difficult. Successful validation of an antibody requires the use of multiple detection methods with the ability to compare appropriate positive and negative controls. Here, we describe in detail the protocols used to validate a mouse-specific PDL-1 antibody used in immunohistochemistry staining with an mRNA in situ hybridization on adjacent sections of mouse B16 tumor...

A complex composed of goat anti-rabbit secondary antibody conjugated to a polymer coated with horseradish peroxidase (HRP) molecules was used to develop rapid and highly sensitive immunostaining protocol for the detection of phosphorylated p27/Kip1 (T157) in human tissues. This polymer-HRP complex produced much better sensitivity detection compared to conventional biotin-streptavidin-HRP chemistry. Using polymer-HRP made it possible to reduce primary antibody concentration, eliminate some incubation steps such as avidin-biotin blocking and incubation with separate biotinylated secondary antibodies, and shorten the incubation time with primary antibody...

α1-antitrypsin (AAT) is a 52kDa serine protease inhibitor that is abundant in plasma. It is synthesized mainly by hepatic cells, and widely used to treat patients with emphysema due to congenital deficiency of AAT. A new isolation method for the purification of AAT from Cohn Fraction IV (Cohn F IV) is described. Cohn F IV is usually discarded as a byproduct from Cohn process. Using Cohn F IV as starting material does not interfere with the production of other plasma proteins and the cost of purification could be reduced greatly...

The plant cell wall is a source of fermentable sugars in second-generation bioethanol production. However, cellulosic biomass hydrolysis remains an obstacle to bioethanol production in an efficient and low-cost process. Clostridium thermocellum has been studied as a model organism able to produce enzymatic blends that efficiently degrade lignocellulosic biomass, and also as a fermentative microorganism in a consolidated process for the conversion of lignocellulose to bioethanol. In this study, a C. thermocellum strain (designated B8) isolated from goat rumen was characterized for its ability to grow on sugarcane straw and cotton waste, and to produce cellulosomes...

Natural killer (NK) cells are a diverse population of lymphocytes with a range of biological roles including essential immune functions. NK cell diversity is in part created by the differential expression of cell surface receptors which modulate activation and function, including multiple subfamilies of C-type lectin receptors encoded within the NK complex (NKC). Little is known about the gene content of the NKC beyond rodent and primate lineages, other than it appears to be extremely variable between mammalian groups...

Ghrelin is the only known hormone posttranslationally modified with an acylation. This modification is crucial for most of ghrelin's physiological effects and is catalyzed by the polytopic enzyme ghrelin O-acyltransferase (GOAT). The aim of this study was to characterize GOAT in a teleost model, goldfish (Carassius auratus). First, the full-length cDNA sequence was obtained by RT-PCR and rapid amplification of cDNA ends methods. Two highly homologous cDNAs of 1491 and 1413 bp, respectively, named goat-V1 and goat-V2 were identified...
