Several long-term intervention trials only studied the ex vivo immunological function to elucidate the beneficial mechanisms of n-3 polyunsaturated fatty acids (PUFA) in the ulcerative colitis (UC). An unbiased whole-transcriptome analysis would be more valuable to obtain a comprehensive understanding of the processes and genes regulated by n-3 PUFA in vivo. In this study, we have performed microarray analysis in the colon tissues of dextran sulfate sodium (DSS)-induced UC in rats supplemented with n-6 PUFA, n-3PUFA and long-chain n-3PUFA (LC-n3PUFA)...

As cerebellar granule cells (GCs) coordinate the formation of regular cerebellar networks during postnatal development, molecules in GCs are expected to be involved. Here, we test the effects of the knockdown (KD) of multiple epidermal growth factor-like domains protein 11 (MEGF11), which is a homolog of proteins mediating astrocytic phagocytosis but is substantially increased at the later developmental stages of GCs on cerebellar development. MEGF11-KD in GCs of developing mice results in abnormal cerebellar structures, including extensively ectopic Purkinje cell (PC) somas, and in impaired motor functions...

Native breeds in any country are a national capital, and their preservation is of great importance. Native Cattle of Guilan (NCG) is one of the few pure native breeds in Iran and the West Asia region. During the last decade, NCG population has decreased by more than 40%. This study aimed to identify significant single nucleotide polymorphisms (SNPs) and candidate genes associated with meat production traits in NCG using a genome-wide association study (GWAS). The blood and hair samples were collected from 72 NCG individuals and genotyped using the Illumina Bovine SNP50 chip...

Exposure to phthalates has been shown to impede the human endocrine system, resulting in deleterious effects on pregnant women and their children. Phthalates modify DNA methylation patterns in infant cord blood. We examined the association between prenatal phthalate exposure and DNA methylation patterns in cord blood in a Korean birth cohort. Phthalate levels were measured in 274 maternal urine samples obtained during late pregnancy and 102 neonatal urine samples obtained at birth, and DNA methylation levels were measured in cord blood samples...

AIMS: The aim of this study was to test the hypothesis that overexpression of the Multiple Epidermal Growth Factor Like Domains 11 (MEGF11) gene in TNBC cells increases tumor cell survival against anoikis via interaction with platelets. MAIN METHODS: The role of MEGF11 was studied in human TNBC MDA-MB-231 and MDA-MB-468 cells by overexpressing MEGF11 (o/e MEGF11) using non-attached culture. Mouse wild type 4 T1 and Δmegf11-4 T1 cells were implanted into the mammary fat pad of BALB/c mice...

INTRODUCTION: The current study aimed to describe genotypes associated with Hodgkin lymphoma (HL) in a cohort of Saudi and non-Saudi patients and discuss their possible susceptibility to HL. METHODS: We studied clinical, histopathological, and laboratory findings of HL patients admitted over 12 years duration, at King Fahd University Hospital, KSA. The genomic DNAs of HL patients (n = 61) and normal control subjects (n = 36) were extracted, and genotyping was performed using the Illumina human exome bead chip...

BACKGROUND: Specific adaptive features including disease resistance and growth abilities in harsh environments are attributed to indigenous cattle breeds of Benin, but these breeds are endangered due to crossbreeding. So far, there is a lack of systematic trait recording, being the basis for breed characterizations, and for structured breeding program designs aiming on conservation. Bridging this gap, own phenotyping for morphological traits considered measurements for height at withers (HAW), sacrum height (SH), heart girth (HG), hip width (HW), body length (BL) and ear length (EL), including 449 cattle from the four indigenous Benin breeds Lagune, Somba, Borgou and Pabli...

Our previous study demonstrated that upregulation of multiple epidermal growth factor-like domains 11 (MEGF11) gene expression is involved in the mechanism by which recurrence of Triple Negative Breast Cancer (TNBC) occurs. Our aim was to elucidate the role of MEGF11 expression in TNBC cells, both in vitro and in vivo, and in human tissue. Following MEGF11 gene knockdown (∆MEGF11) or over-expression in MDA-MB-231 and MB-468 cells, cell growth and chemokine gene expression were evaluated. In vivo, tumour growth of implanted human TNBC cells and the number of circulating 4T1 mouse tumour cells were measured...

Mutations in the gene encoding the single transmembrane receptor multiple epidermal growth factor-like domain 10 (MEGF10) cause an autosomal recessive congenital muscle disease in humans. Although mammalian MEGF10 is expressed in the central nervous system as well as in skeletal muscle, patients carrying mutations in MEGF10 do not show symptoms of central nervous system dysfunction. drpr is the sole Drosophila homolog of the human genes MEGF10, MEGF11, and MEGF12 (JEDI, PEAR). The functional domains of MEGF10 and drpr bear striking similarities, and residues affected by MEGF10 mutations in humans are conserved in drpr...

Adenylate cyclase 3 (AC3) is one of the major players in the olfactory signaling within the main olfactory epithelium (MOE) of mice. However, we are not ascertained whether deficiency of AC3 will lead to the differential expression of related genes in the MOE. Forward and reverse subtractive libraries were constructed by suppression subtractive hybridization (SSH) approach, with MOEs from AC3(-/-) and AC3(+/+) mice. These two libraries were primarily screened by Dot blot, differential expressed clones were sequenced and analyzed by bioinformatics, and differential expressed genes were verified by qRT-PCR...

During neocortical development, excitatory neurons are produced from apical progenitors in the ventricular zone (VZ) or from dividing cells in the subventricular zone (SVZ). We previously reported that the direct progenies of VZ cells in mice slowly exit the VZ and accumulate just above the VZ (lower SVZ) as multipolar migrating neurons, whereas subsequently dividing cells in the SVZ exit the VZ earlier than the former and become widely distributed in the SVZ. These two populations are named the slowly exiting population (SEP) and the rapidly exiting population (REP), respectively...

In many parts of the nervous system, neuronal somata display orderly spatial arrangements. In the retina, neurons of numerous individual subtypes form regular arrays called mosaics: they are less likely to be near neighbours of the same subtype than would occur by chance, resulting in 'exclusion zones' that separate them. Mosaic arrangements provide a mechanism to distribute each cell type evenly across the retina, ensuring that all parts of the visual field have access to a full set of processing elements...

Self-renewal and differentiation of hematopoietic stem and progenitor cells are defined by the ensembles of genes expressed by these cells. Here we report identification of a novel gene named Jedi, which is expressed predominantly in short- and long-term repopulating stem cells when compared to more mature bone marrow progenitors. Jedi mRNA encodes a transmembrane protein that contains multiple EGF-like repeats. Jedi and two earlier reported proteins, MEGF10 and MEGF11, share a substantial homology and are likely to represent a novel protein family...

To accumulate information on the coding sequences of unidentified genes, we have carried out a sequencing project of human cDNA clones which encode large proteins. We herein present the entire sequences of 100 cDNA clones of unidentified human genes, named KIAA1776 and KIAA1780-KIAA1878, from size-fractionated cDNA libraries derived from human fetal brain, adult whole brain, hippocampus and amygdala. Most of the cDNA clones to be entirely sequenced were selected as cDNAs which were shown to have coding potentiality by in vitro transcription/translation experiments, and some clones were chosen by using computer-assisted analysis of terminal sequences of cDNAs...
