We screened for endoplasmic reticulum (ER) stress-resistant mutants among 25 mutants of the Arabidopsis NTL (NAC with Transmembrane motif 1-Like) family. We identified a novel mutant, SALK_044777, showing strong resistance to ER stress. RT-PCR and genomic DNA sequence analyses identified the mutant as atntl7, which harbors a T-DNA insertion in the fourth exon of AtNTL7. Two other atntl7-mutant alleles, in which T-DNA was inserted in the second exon and third intron of AtNTL7, respectively, showed ER-stress sensitive phenotypes, suggesting that SALK_044777 is a gain-of-function mutant...

The porcine kobuvirus 1 (PKV-1) is believed to be an enteric virus. To investigate the prevalence of PKV-1 in pigs, virus was detected by RT-PCR in rectal swabs originating from 414 healthy and diarrheic pigs of different age categories on farms in Slovakia. Among all ages of animals, PKV-1 was detected equally in diarrheic (63.8%) and clinically healthy (62.9%) pigs. PKV-1 was more often detected in diarrheic (74.6%) than in healthy (64.4%) suckling piglets (<28days) but data was not statistically significant...

Androgens and androgen receptor (AR) signaling play important roles throughout development. In the chicken, AR signaling is involved in reproduction; however, its specific role is unclear. We show that AR signaling is involved in the normal development of the female embryonic gonads. The AR mRNA level was detected in male and female embryonic gonads by quantitative RT-PCR, and its expression was higher in females than in males at all developmental stages examined. In female embryos, the AR localized to nuclei of cells in the left gonad...

The regeneration of articular cartilage remains an unresolved question despite the current access to a variety of tissue scaffolds activated with growth factors relevant to this application. Further advances might result from combining more than one of these factors; here, we propose a scaffold composition optimized for the dual delivery of BMP-7 and TGF-β3, two proteins with described chondrogenic activity. First, we tested in a mesenchymal stem cell micromass culture with TGF-β3 whether the exposure to microspheres loaded with BMP-7 would improve cartilage formation...

BACKGROUND: α/β-Hydrolase domain 6 (ABHD6) is one of the major enzymes for endocannabinoid 2-arachidonoylglycerol (2-AG) hydrolysis in microglia cells. Our recent studies have shown that a selective ABHD6 inhibitor WWL70 has anti-inflammatory and neuroprotective effects in animal models of traumatic brain injury and multiple sclerosis. However, the role of ABHD6 in the neuroinflammatory response and the mechanisms by which WWL70 suppresses inflammation has not yet been elucidated in reactive microglia...

BACKGROUND: Despite new treatment options for hepatocellular carcinomas (HCC) recently, 5-year survival remains poor, ranging from 50 to 70%, which may attribute to the lack of early diagnostic biomarkers. Thus, developing new biomarkers for early diagnosis of HCC, is extremely urgent, aiming to decrease HCC-related deaths. METHODS: In the study, we conducted a comprehensive characterization of gene expression data of HCC based on a bioinformatics method. The results were confirmed by real time polymerase chain reaction (RT-PCR) and TCGA database to prove the credibility of this integrated analysis...

BACKGROUND: Due to their self-renewal capacity, multi-lineage potential, and immunomodulatory properties, mesenchymal stromal cells (MSCs) are an attractive tool for different therapeutic strategies. Foreskin (FSK), considered as a biological waste material, has already been shown to be a valuable source of MSCs. Besides their typical fibroblast like morphology and International Society for cellular Therapy compliant phenotype, foreskin-MSCs (FSK-MSCs) are clonogenic, and highly proliferative cells with multi-lineage and strong immunomodulatory capacities...

Comparative genomic hybridization (CGH) is a powerful tool used to analyze changes in copy number, polymorphisms, and structural variations in the genome. Gene copy number variation (CNV) is a common form of natural diversity in the genome, which can create new genes and alter gene structure. Thus, CNVs may influence phenotypic variation and gene expression. In this study, to detect CNVs, we irradiated rice seeds with gamma rays (300 Gy) and selected two dwarf mutagenized plants, GA-III-189 and -1052, in the M3 generation...
