Differential miRNAs between Sensitive and Resistant Pig to Escherichia coli F18 by deep sequencing

ABSTRACT: An M307 G/A point mutation of FUT1 gene has been considered as a usful marker to select the piglets that are sensitive(GG/AG genotype) or resistant(AA) to Escherichia coli F18 in foreign pig breeds. However,it is not suitable to Chinese native breeds. Duodenal tissues were collected from 3 full-sib pairs of Sutai pigs (a new hybrid between the Duroc and Taihu breeds) at the age of 28-day differing in adhesion phenotype to find the differential miRNAs that can provide the basis for analyzing the different mechanisms of E.coli F18 resistance between foreign and Chinese native breeds,as well as for breeding for disease resistance in Chinese native breeds in the future. piglets at the age of 28-day sensitive(GG genotype) to Escherichia coli F18 vs resistant(AA) ones.Biological replicates:3 full-sib pairs of Sutai pigs(3 pairs for GG/AA genotype of FUT1 gene).One GG sample (512 piglet) was sequenced twice to verify the result. 2385 piglet and 2383 piglet were a pair of full-sib with AA and GG genotype at M307 positionof FUT1 gene, respectively. Unfortunately, the sequencing of 2385 was a failure and was excluded. 2385 piglet has an AA genotype of the FUT1 gene

RNA-seq for miRNAs in fibrocyte-adipocyte progenitors (FAPs) or myogenic progenitors (MPs) during muscle regeneration

Project description:In order to understand the role of miRNAs in muscle regeneration we injected cardiotoxin into the tibialis muscle of mice and isolated using FACS two different groups of adult muscle stem cells. RNA was isolated directly from sorted cells and analyzed by miRNA deep sequencing.

Trans-interaction of risk loci 6p24.1 and 10q11.21 is associated with endothelial damage in coronary artery disease

Project description:The variant rs6903956 has been identified as one of the Asian-specific genetic risk factors for coronary artery disease (CAD). However, rs6903956 lies in a non-coding locus on chromosome 6p24.1, hampering efforts of functional annotation. We produced induced pluripotent stem cells (iPSCs) from CAD patients (AA risk genotype at rs6903956) and normal controls (GG non-risk genotype at rs6903956). CRIPSR-Cas9-based deletions (Δ63-89bp) on 6p24.1 including rs6903956 were performed to generate isogenic iPSC-derived endothelial cells. Edited CAD endothelial cells exhibited a global transcriptional downregulation of pathways relating to abnormal vascular physiology and activated endothelial processes. Surprisingly, deletions on either risk or non-risk 6p24.1 locus had minimal influence on cis gene expressions. Instead, a CXC chemokine ligand on chromosome 10q11.21, CXCL12, was uncovered as a potential effector gene in CAD endothelial cells. Underlying this effect was the preferential inter-chromosomal interaction of 6p24.1 risk locus to a weak promoter of CXCL12, confirmed by chromatin conformation capture assays on our iPSC-derived endothelial cells. Functionally, risk genotypes AA/ AG at rs6903956 were associated significantly with elevated levels of circulating damaged endothelial cells in CAD patients. Circulating endothelial cells isolated from patients with risk genotypes AA/ AG were also found to have 10 folds higher CXCL12 transcript copies/ cell than those with non-risk genotype GG. Our study reveals the trans-acting impact of 6p24.1 risk locus, involving the atherosclerosis-implicated gene CXCL12, and is associated with intensified endothelial injury.

Muscle Transcriptomic Investigation of Late Fetal Development Identifies Candidate Genes for Key Roles in Piglet Maturity

Project description:To further knowledge of piglet maturity, we have developed a microarray analysis to describe biological processes and to find candidate genes for key roles in piglet maturity. The objective was to identify which genes and biological processes are specifically involved in the difference between two extreme breeds: Large White (LW) and Meishan (MS). The LW breed is a selected breed known to show an increased rate of mortality at birth, while the MS breed presents more robust piglets at birth. MS and LW sows were inseminated with mixed semen (LW and MS) hence each litter was composed of pure fetuses (LW or MS) and crossed fetuses (LWMS from MS sows and MSLW from LW sows). To assay for changes in gene expression during piglet maturity, mRNA was isolated from 61 fetal skeletal muscle samples with 8 different conditions: two fetal gestational ages (90 or 110 days of gestation), associated with four genotypes (two extreme breeds for mortality at birth (MS and LW) and two crossed breeds (MSLW and LWMS)). MS fetuses are known to have a better survival at birth than LW fetuses. An understanding of maturity is possible with the comparison between the fetal gestational ages and between the two extreme breeds. The impact of parental genotypes is studied with the presence of crossed fetuses. After quality control and normalization, only 61 samples were conserved (represented here).

Microarray profiling for differential gene expression in PSMG-hCG stimulated pre-ovulatory ovarian follicles of Chinese Erhualian and Large White sows

Project description:The Chinese Erhualian is one of the most prolific pig breeds in the world, which farrows at least five more piglets per litter than Western pig breeds partly due to a greater ovulation rate. Differences in the transcriptome of Chinese Erhualian and Large White ovaries directly result in variation of ovulation rate. To understand the molecular basis related to ovulation rate in Chinese indigenous and Western breeds, samples were collected and used to hybridized. This study reveals many potential avenues of investigation for seeking new insights into ovarian physiology and the genetic control of reproduction.

Trancription profiling of pig placenta, Erhualian pigs and Large White pigs, gestation day 75 and 90

Project description:From gestation day 75 to gestation day 90, an important stage for the placental and fetal development, the fetuses grow rapidly and need adequate nutrition. The Meishan pigs and the Large White pigs employ different ways in supplying the enough nutrients and oxygen to the fetus. The Meishan pigs increased the vascular density and the Large White pigs have the second increase in the surface of placenta. To understand the molecular basis related to late gestation placenta development in Chinese indigenous and Western breeds with different placental efficiency, samples were collected and used to hybridized. The results offered new data on understanding the molecular basis of placenta efficiency, and indicated that Erhualian pigs had the more efficient than the Large White pigs. Experiment Overall Design: Placenta efficiency (the body weight of a piglet divided by the mass of its placenta) of Erhualian pigs is markedly higher than Large White pigs. so placenta samples (female) from 6 Erhuanlian pregnant gilts at gestation day 75 (E75) and day 90 (E90) and 6 Large White pregnant gilts at gestation day 75 (L75) and day 90 (L90) were collected. RNAs from two female piglet placentas from each gilt were combined to 12 pools and hybridized to the porcine Affymetrix GeneChip.

Developing seeds of M955 low phytic acid barley 7 days after anthesis

Project description:Effect of the low phytic acid mutation on gene expression of developing seeds of M955, a low phytic acid barley genotype with >90% reduction in phytic acid in mature seeds. Expression analysis using the Barley1 GeneChip was performed on total RNA from developing seeds (7DAA) of M955 lpa and wt sib-selections. Sib-selections were from BC2 populations of M955 with Harrington as the recurrent parent. Material was grown in field trials in two years 2003 and 2004. In 2003 expression analysis was done from 2 lpa and 3 wt sib-selections, and in 2004 analysis was done from 2 lpa and 2 wt sib-selections. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, David Bowen.
