Beak and feather disease virus (BFDV) belongs to the Circoviridae family, which has a relatively simple replication mechanism. As BFDV lacks a mature cell culture system, a novel mini-replicon system based on the reporter plasmid that contains the origin of replication, which can bind to the Rep protein expressed from another plasmid and thus trigger its replication and induce/increase luminescence was developed. The dual-luciferase assay was used in this system to measure replicative efficiency by comparing relative light units (RLU) of firefly luciferase...

Orf147, a cytotoxic peptide, has been found to cause cytoplasmic male sterility (CMS) in Cajanus cajanifolius (pigeonpea).

BACKGROUND: Aberrant promoter methylation of CpG islands plays an important role in carcinogenesis. However, the association between the DNA methylation of JAK-STAT pathway-related genes in peripheral blood leukocytes and colorectal cancer (CRC) susceptibility remains unclear. METHODS: We conducted a case-control study of 403 patients with CRC and 419 cancer free controls, and the DNA methylation levels of JAK2, STAT1, STAT3, and SOCS3 in peripheral blood samples from all subjects were assessed using a methylation-sensitive high-resolution melting (MS-HRM) analysis...

Duchenne muscular dystrophy (DMD) is caused by the dystrophin gene mutations and is one of the most common and lethal human hereditary disorders. A novel therapeutic approach using CRISPR technology has gained attention in the treatment of DMD. Gene replacement strategies are being proposed as a promising therapeutic option to compensate the loss of function mutations. Although, the large size of the dystrophin gene and the limitations of the existing gene replacement approach, could mean the gene delivery of shortened versions of dystrophin such as midystrophin and microdystrophins...

lactoferrin (Lf) is a glycoprotein with various biological activities, including antibacterial, antiviral, anti-cancer, etc. In the present study, the effect of different concentrations of nano-encapsulated lactoferrin (NE-Lf) on the expression of Bax and Bak genes was evaluated in stomach cancer cell line AGS using real-time PCR technique and cytotoxicity of NE-Lf on the growth cells as well as the molecular mechanism of these two genes and their proteins in the apoptosis pathway and the relationship between lactoferrin and these proteins were investigated by bioinformatics studies...

Staphylococcus gallinarum FCW1 was isolated from naturally fermented coconut-water and identified by biochemical and molecular methods. Probiotic characterization and safety assessment were conducted through a series of in vitro tests. A high survival rate was observed when the strain was tested for resistance to bile, lysozyme, simulated gastric and intestinal fluid, phenol, and different temperature and salt concentrations. The strain showed antagonism against some pathogens, was susceptible to all antibiotics tested except penicillin, and showed no hemolytic and DNase activity...

BACKGROUND AND AIM: Schizophrenia is one of the most severe psychiatric disorders. About 0.5 to 1% of the world's population suffers from this non-Mendelian disorder. Environmental and genetic factors seem to be involved in this disorder. In this article, we investigate the alleles and genotypic correlation of mononucleotide rs35753505 polymorphism of Neuregulin 1 (NRG1), one of the selected genes of schizophrenia, with psychopathology and intelligence. MATERIALS AND METHODS: 102 independent and 98 healthy patients participated in this study...

Taraxacum kok-saghyz has been identified as one of the most promising alternative rubber crops, with laticifer cells that produce high-quality rubber. To uncover the underlying molecular mechanisms regulating natural rubber biosynthesis under MeJA induction, a reference transcriptome was constructed from nine samples of T. kok-saghyz. MeJA treatment was applied for 0 h (control), 6 h, and 24 h. A total of 7452 differentially expressed genes (DEGs) were identified in response to MeJA stress, relative to the control...

NRXN3geneencodesneurexin-III which is a Neural Cell Adhesion Molecule (NCAM) with important synaptic functions in the brain. Neurexin-III deficiency could affect synapse development, synaptic signaling and neurotransmitter release. Hitherto, there is no related disorder in the OMIM due to NRXN3 mutation. In this study, two unrelated Iranian families with homozygous (NM_001330195.2:c.3995G>A, p.Arg1332His) and compound heterozygous (NM_001330195.2:c.4442G>A, p.Arg1481Gln; c.3142+3A>G) variants in theNRXN3gene were detected for the first time...

Cell division cycle associated 8 (CDCA8) is a component of the chromosomal passenger complex and plays an essential role in mitosis, meiosis, cancer growth, and undifferentiated state of embryonic stem cells. However, its expression and role in adult tissues remain largely uncharacterized. Here, we studied the CDCA8 transcription in adult tissues by generating a transgenic mouse model, in which the luciferase was driven by a 1-kb human CDCA8 promoter. Our previous study showed that this 1-kb promoter was active enough to dictate reporter expression faithfully reflecting endogenous CDCA8 expression...

Recently, aberrant DNA methylation of the HIST1H4F gene (encodes Histone 4 protein) has been shown in many types of cancer, which may serve as a promising biomarker for early cancer diagnosis. However, the correlation between DNA methylation of the HIST1H4F gene and its role in gene expression is unclear in bladder cancer. Therefore, the first objective of this study is to explore the DNA methylation pattern of the HIST1H4F gene and then further elucidate its effects on HIST1H4F mRNA expression in bladder cancer...

The nucleolar rRNA 2'-O-methyltransferase fibrillarin (FBL) contains a highly conserved methyltransferase domain at the C-terminus and a diverse glycine arginine-rich (GAR) domain at the N-terminus in eukaryotes. We found that a nine-exon configuration of fbl and exon 2-3 encoded GAR domain are conserved and specific in vertebrates. All internal exons except exon 2 and 3 are of the same lengths in different vertebrate lineages. The lengths of exon 2 and 3 vary in different vertebrate species but the ones with longer exon 2 usually have shorter exon 3 complementarily, limiting lengths of the GAR domain within a certain range...

To survive under harsh environments, embryonic development of Artemia was arrested at the gastrula stage and released as the diapause embryo. Cell cycle and metabolism were highly suppressed in this state of quiescence. However, cellular mechanisms underlying diapause remain largely unclear. In this study, we found that the expression level of a CT10 regulator of kinase-encoding gene (Ar-Crk) in diapause embryos was significantly lower than non-diapause embryos at the early embryogenetic stage of Artemia. Knockdown of Ar-Crk by RNA interference induced formation of diapause embryos, while the control group produced nauplii...

Toll-like receptor (TLR) 22 is a non-mammalian TLR, which is identified initially as a functional substitute of mammalian TLR3 in recognizing cell surface long dsRNA in teleosts. To understand the pathogen surveillance role played by TLR22 in an air-breathing catfish model the full-length cDNA of TLR22 was identified in Clarias magur and found to be consisted of 3597 nucleotides encoding for 966 amino acids. In the deduced amino acid sequence of C. magur TLR22 (CmTLR22) key signature domains such as one signal peptide, 13 LRRs, one transmembrane domain, one LRR_CT domain and an intracellular TIR domain could be identified...
