Project description:Here, we performed the first whole-genome bisulfite sequencing (WGBS) of longissimus dorsi muscle (LDM) from Landrace (LR) and Wuzhishan (WZS) miniature pig during early embryonic stages (18, 21 and 28 dpc (days post coitum)).
Project description:Miniature pig is a useful animal model to clarify the vital reaction and the molecular mechanisms. However, physiclogical response of pig model to sodium azide (AZIDE) stress is not reveal. To establishment of large animal model for evaluate toxic stress, whole blood of miniature pig were assessed with genomics. 7 month old clawn miniature pigs were fed AZIDE feeding. AZIDE dose of 300µg/kg, one hundredth of LD50 was given orally to the miniature pigs. Whole blood gene expression was measured at 0h, 6h and 24h after feeding.
Project description:By combining isobaric tandem mass tag (TMT) labeling with liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) technology, we constructed protein regulated profiles of deciduous molar germ at embryonic days 40 and 50 ,60 in miniature pig.

Project description:Dysregulation of lipid metabolism is the pathological basis of the occurrence and development of atherosclerosis.The pig is an ideal animal to study human cardiovascular diseases. However, the specific changes of lipid metabolism in its atherosclerotic plaques, as well as the underlying mechanisms, remain to be elucidated. To investigate the alterations of lipid metabolism related pathways, especially ceramide synthesis related genes, in the abdominal aorta of atherosclerotic pigs induced by high-fat, high-cholesterol, and high-fructose (HFCF) diet, we performed RNA-Seq on abdominal aorta tissue from Wuzhishan pigs fed either normal chow diet or HFCF diet for six months.
Project description:ChIP-seq of embryonic muscle sample of Landrace and Wuzhishan pig breeds from embryonic day 35 and 28 dpc were conducted using H3K4me3 and H3K27me3 antibody.
Project description:Here, we performed the first iTRAQ-based proteomic analysis of early embryonic longissimus dorsi muscle from Landrance (LR) and miniature pig (Wuzhishan WZS) ranging from 21 to 42 days post coitus (dpc). 4431 proteins were identified. In both WZS and LR, the largest amount of differentially expressed proteins (DEPs) were found between 28 and 35 dpc. 252 breed-DEPs were selected by GO analysis, including 8 myofibrillar proteins. Only MYHCⅠ/IIA mRNA were detected due to early embryonic stages, and significantly higher expression of them were found in WZS during these 4 stages. MYHCⅠ was first found in WZS at 28 dpc and expressed in both breeds at later stages, while MYHCII protein was not detected until 35 dpc in both breeds. Thus, 33 myogenic breed-DEPs selected from last two stages were analyzed by STRING, which showed that some myofibrillar proteins (MYH1, TPM4, MYH10, et.al) and functional proteins (CSRP2, CASQ2, OTC, et.al), together with candidate myogenic proteins (H3F3A, HDGFRP2, et.al), probably participate in the regulatory network of myofiber formation. Thus, our study provides new data on myofiber type development during early embryo stages, which contributes to the improved understanding in the regulation mechanism of early myogenesis in agricultural animals.
Project description:Shochu distilled water (SDW) was used as a feedstuff for livestock. We have tried to evaluate the physiology of pig during feeding SDW using genomics. 8-9 month old clawn miniature pigs were fed standard dry feed or SDW feeding. SDW feeding composed of standard dry feed: water: SDW= 1:1:1 by the weight ratio.Whole blood gene expression in control and SDW animal was measured at 12 weeks of feeding periods.
