Comparative analyses of sperm DNA methylomes among three commercial pig breeds reveal vital hypomethylated regions associated with spermatogenesis and embryonic development

ABSTRACT: This study is the first to report a genome-wide comparative DNA methylation map of adult pig sperm in three commercial pig breeds using WGBS technology. Our results showed that DNA methylation was more conserved in the three commercial pig breeds. Moreover, our results indicated that breed-specific HMRs are related to phenotypic changes and economically complex traits for each breed. The conserved HMRs between pig sperm and testis close to or located in the promoter regions of important genes are mainly involved in DNA repair and spermatogenesis.

CGH analyses for the Chinese indigenous pig breeds and commercial pig breeds [Agilent]

Project description:Since CNVs play a vital role in genomic studies, it is an imperative need to develop a comprehensive, more accurate and higher resolution porcine CNV map with practical significance in follow-up CNV functional analyses To detect CNV of pigs, we performed high density aCGH data of diverse pig breeds in the framework of the pig draft genome sequence (Sscrofa10.2) 9 Chinese indigenous pig, one Chinese wild boar and 2 commercial pigs were detected using one pig of Duroc as reference. These 12 animals include 1 wild pig, 2 pigs each from Yorkshire and Landrace as the representatives of modern commercial breeds and 9 unrelated individuals selected from 6 Chinese indigenous breeds (2- Tibetan pig, 2- Diannan small-ear pig, 2-Meishan pig, 1- Min pig, 1-Daweizi pig, and 1-Rongchang pig).

Global patterns of the methylome in porcine liver

Project description:To explore the methylome differences of swine breeds with different traits of commercial interest, we sampled liver tissues from a Chinese well-known elite native breed of Enshi black pig, a Large White pig, and a Chinese wild boar living within the same environment at the same daya-old (90d).

Identification of genes in longissimus dorsi muscle differentially expressed between Wannanhua and Yorkshire pigs using RNA sequencing

Project description:Western commercial pig breeds have been intensively selected, resulting in a sizeable, rapid, and efficient accretion of muscle but a reduction in meat quality. When compared with Western commercial pig breeds, Chinese indigenous pig breeds exhibited slower growth rates and reduced lean meat content but superior perceived meat quality. To study the factors that determine meat quality, we examined piglets of one Western commercial breed (Yorkshire) and one Chinese indigenous breed (Wannanhua) and sequenced the longissimus dorsi muscle using RNA-sequencing (RNA-seq). We analyzed their transcriptomes, focusing on identifying candidate genes that may influence porcine muscle growth, meat quality and adipose deposition. Gene ontology functional enrichment and pathway enrichment analyses identified differentially expressed genes primarily associated with glycolytic metabolism, biological processes of muscle development and signaling pathways related to fatty acid metabolism, growth and carcass traits. This finding suggests that the differentially expressed genes may play important roles in determining meat quality traits. Quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR) confirmed the differential expression of twelve selected differentially expressed genes. This study identified a number of novel candidate genes for porcine meat quality and carcass traits that merit further investigation to elucidate the molecular mechanisms responsible for muscle growth and fat deposition.

An atlas of mRNA expression in pig adipose and muscle tissues

Project description:Obese and lean-type pig breeds show obvious differences in adipose deposition and muscle growth; however, the molecular mechanisms underlying this phenotypic variation remains unclear. Landrace (a leaner, Western breed), Rongchang (a fatty, Chinese breed) and Tibetan (a feral, indigenous Chinese breed that has not undergone artificial selection) pig breeds were used in this study. We collected eight diverse adipose tissues and two phenotypically distinct skeletal muscle tissues from three well-defined pig models with distinct fat rates, and studied mRNA expression differences among breeds, males and females, and tissues. These results highlight some possible candidate genes for porcine adipose deposition and muscle growth and provide some data on which to base further studies of the molecular basis of energy metabolism.

Newcastle Disease virus infection in chickens

Project description:Airway epithelial cells from 3 different breeds of chicken infected with Newcastle Disease virus were sequenced and compared to cells from uninfected control birds. The 3 breeds were an indigenous breed, commercial Rhode Island Reds and a hybrid breed (Kenbro).
