48, 95% CI = 1.03-2.12, P = 0.035). The stratified analysis further revealed that carriers of 2-4 risk genotypes are more susceptible to hepatoblastoma in the subgroups of subjects aged under 17 months (adjusted OR = 1.88, 95% CI = 1.12-3.16, P = 0.016) and females (adjusted OR = 1.79, 95% CI = 1.06-3.05, P = 0.031). Overall, our results revealed that none of these four SNPs could increase susceptibility to hepatoblastoma individually. Carriers with 2-4 risk genotypes in the combined analysis tend to increase the risk of hepatoblastoma.Defensins represent a family of cysteine-rich peptides that have broad-spectrum antimicrobial activities and serve as a typical kind of effector molecule in the immunity. Ruminant species have a large number of β-defensins in the absence of α- and θ-defensins. It is well-known that the genomes of sheep and cattle harbor at least 43 and 57 β-defensin genes, respectively. However, the repertoire of the goat β-defensin gene family has not been fully elucidated. In this study, we identified a total of 50 β-defensins from the goat genome, including 48 functional genes and 2 pseudogenes. Cross-species genomic and evolutionary analyses showed that all of the β-defensins in goat chromosomes 8, 13 and 23 present one-to-one orthologous relationships to their sheep and cattle counterparts, whereas some β-defensin genes in goat chromosome 27 are goat-specific. Moreover, we observed that some duplicated genes in goat chromosome 27 may be derived from gene copy number variation, and the annotation of sheep and cattle β-defensins appears to be incomplete in the genome. Importantly, real-time PCR analysis showed that 17 β-defensins are expressed in the small intestine with abundant cBD1s expression. These findings significant increased our knowledge of ruminant β-defensin and provided useful information for genetic studies, as well as providing a foundation for future research exploring the role of defensins in the immune response.Mitochondrial sequences were among the first molecular data collected for phylogenetic studies and they are plentiful in DNA sequence archives. However, the future value of mitogenomic data in phylogenetics is uncertain, because its phylogenetic signal sometimes conflicts with that of the nuclear genome. A thorough understanding of the causes and prevalence of cyto-nuclear discordance would aid in reconciling different results owing to sequence data type, and provide a framework for interpreting megaphylogenies when taxa which lack substantial nuclear data are placed using mitochondrial data. Here, we examine the prevalence and possible causes of cyto-nuclear discordance in the landfowl (Aves Galliformes), leveraging 47 new mitogenomes assembled from off-target reads recovered as part of a target-capture study. check details We evaluated two hypotheses, that cyto-nuclear discordance is "genuine" and a result of biological processes such as incomplete lineage sorting or introgression, and that cyto-nuclear discordance is an artifact of inaccurate mitochondrial tree estimation (the "inaccurate estimation" hypothesis). We identified seven well-supported topological differences between the mitogenomic tree and trees based on nuclear data. These well-supported topological differences were robust to model selection. An examination of sites suggests these differences were driven by small number of sites, particularly from third-codon positions, suggesting that they were not confounded by convergent directional selection. Hence, the hypothesis of genuine discordance was supported.Cerebellins (CBLN1-4), together with C1qTNF proteins, belong to the CBLN subfamily of C1q proteins. Cerebellin-1 (CBLN1) is active in synapse formation and functions at the parallel fiber-Purkinje cell synapses. Cerebellins form tripartite complexes with neurexins and the glutamate-receptor-related proteins GluD1 and GluD2, playing a role as trans-synaptic cell-adhesion molecules that critically contribute to both synapse formation and functioning and brain development. In this study, I present a molecular characterization of the four porcine CBLN genes. Experimental data and in silico analyses collectively describes the gene structure, chromosomal localization, and expression of CBLN1-4. Two cDNAs encoding the cerebellins CBLN1 and CBLN3 were RT-PCR cloned and sequenced. The nucleotide sequence of the CBLN1 clone contains an open reading frame of 582 nucleotides and encodes a protein of 193 amino acids. The deduced amino acid of the porcine CBLN1 protein was 99% identical to both mouse CBLN1 and to human CBL (GenBank ID FJ196070).Treatment of serum-starved quiescent human cells with fetal bovine serum (FBS), epidermal growth factor (EGF), or the phorbol ester (12-O-tetradecanoylphorbol-13-acetate, TPA) activates the RAS-MAPK pathway which initiates a transcriptional program which drives cells toward proliferation. Stimulation of the RAS-MAPK pathway activates mitogen- and stress-activated kinases (MSK) 1 and 2, which phosphorylate histone H3 at S10 (H3S10ph) or S28 (H3S28ph) (nucleosomal response) located at the regulatory regions of immediate-early genes, setting in motion a series of chromatin remodeling events that result in transcription initiation. To investigate immediate-early genes regulated by the MSK, we have completed transcriptome analyses (RNA sequencing) of human normal fibroblast cells (CCD-1070Sk) stimulated with EGF or TPA ± H89, a potent MSK/PKA inhibitor. The induction of many immediate-early genes was independent of MSK activity. However, the induction of immediate-early genes attenuated with H89 also had reduced induction with the PKA inhibitor, Rp-cAMPS. Several EGF-induced genes, coding for transcriptional repressors, were further upregulated with H89 but not with Rp-cAMPS, suggesting a role for MSK in modulating the induction level of these genes.As the novel coronavirus SARS-CoV-2 continues to spread in all countries, there is a growing interest in monitoring and understanding the impact of emerging strains on virus transmission and disease severity. Here, we analyzed SARS-CoV-2 genomic sequences reported in the Eastern Mediterranean Region (EMR) countries, as of 1 January 2021. The majority (~75%) of these sequences originated from three out of 22 EMR countries, and 65.8% of all sequences belonged to GISAID clades GR, GH, G and GV. A delay ranging between 30 and 150 days from sample collection to sequence submission was observed across all countries, limiting the utility of such data in informing public health policies. We identified ten common non-synonymous mutations represented among SARS-CoV-2 in the EMR and several country-specific ones. Two substitutions, spike_D614G and NSP12_P323L, were predominantly concurrent in most countries. While the single incidence of NSP12_P323L was positively correlated with higher case fatality rates in EMR, no such association was established for the double (spike_D614G and NSP12_P323L) concurrent variant across the region.
