Transcriptional Profiling of Black and White Skins Reveals Expression Patterns of mRNA and lncRNA changes for lacking melanocyte in Bama pig

Project description:Skin is the largest organ of body, and one function of skin is protecting underly organs away from ultraviolet (UV) radiation damage. Loss of melanocyte will reduce ability of skin to against UV radiation damage. We found Bama Pig can be an ideal model studying loss of melanocyte. In this study, we performed transcriptome profiling of mRNA and long noncoding RNA in Bama pig white skin (absence of melanocyte) and black skin (existence of melanocyte) to provide dataset for clinical researches. Total of 14,900 mRNAs and 7,566 lncRNAs were expressed in the study. Results of hierarchical cluster analysis and principal component analysis (PCA) demonstrated expression of mRNAs and lncRNAs varied greatly between two color skins. 2,342 mRNA were identified as being differentially expressed, including 1,309 genes that were down-regulated in white skin and 1,033 gene that were up-regulated in white skin (P <0.05; |log2(fold change)| > 1). The genes down-regulated in white skin were associated with melanocyte biology, melanocyte function and keratin, while genes up-regulated in white skin were main associated with metabolism pathway, oxidative phosphorylation and citrate cycle (TCA cycle). In addition, we identified 120 differentially expressed lncRNAs. In those lncRNAs, 4 lncRNAs may function in skin biology (TCONS_00019024 and TCONS_00077733) or metabolic (TCONS_00042201 and TCONS_00060772). Our research provides Bama pig skins datasets and could promote clinical researches utilizing Bama pig as model.

Project description:we performed chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-Seq) to profile histone H3 lysine 4 trimethylation (H3K4me3) and histone H3 lysine 27 acetylation (H3K27ac) in pituitary gland of adult Bama Xiang and Large White pigs with divergent evolutionary histories and large phenotypic differences.

Distinct Patterns of Insulin response, sexual development, organ size regulation in postnatal developing Subcutaneous and Visceral fat of Bama Pig

Project description:In this study, the SAF and VAF development was characterized and compared in SAF and VAF of Bama pig during postnatal development (infancy, puberty and adulthood) using RNA sequencing technologies (RNA-Seq). We profiled the transcriptome of SAF and VAF isolated from 1-, 3- and 6-month-old pigs and identified 23636 expressed transcription units. Of the them, 1165 genes were differentially expressed between the despots and /or developmental stages. Upregulated gene in SAF of Bama pigs showed significant function and pathway enrichment in central nervous system development, lipid metabolism, oxidation-reduction process, cell adhesion while genes involved in immune system process, actin cytoskeleton organization, male gonad development, hippo signaling pathway preferentially expressed in VAF. Short time-series expression miner analysis demonstrated the differentiation in gene expression patterns between the two deposit was corresponding to their distinct responses in sextual development, hormone signaling pathway, lipid metabolism as well as hippo signaling pathway. Transcriptome analysis of SAF and VAF in Bama pigs suggested that the depot differences of the adipose tissue are not only related to lipid metabolism and endocrine function, but also closely associated with sextual development and organ size regulation.

Expression data from Bama minipig hearts - high-fat, high-sucrose diet

Project description:In order to study the heart disorder that the long term, high energy diet caused, Bama miniature pigs were fed a high-fat, high-sucrose diet for 23 months. These pigs developed symptoms of metabolic syndrome and showed cardiac steatosis and hypertrophy with a greatly increased heart weight (1.82-fold, P<0.05) and heart volume (1.60-fold, P<0.05) compared with the control pigs. To understand the molecular mechanisms of cardiac steatosis and hypertrophy, nine pig heart cRNA samples were hybridized to porcine GeneChips. The control group consisted of 6 Bama pigs fed a control diet, and the HFHSD group comprised 6 pigs that were induced with a HFHS diet, which included 37% sucrose, 53% control diet and 10% pork lard. The pigs were fed twice every day and provided water ad libitum for 23 months. The pigs were fasted for 12 hours and euthanized with ketamine and xylazine. Pig hearts from the HFHSD group pigs (120, 126, 138, 140, 144, and 146) and three control group pigs (157, 159, and 161) were sampled and preserved in liquid nitrogen and then for RNA extraction and hybridization on Affymetrix microarrays.

Dissection of melanocyte stem cell transcriptomes during melanocyte regeneration in adult zebrafish

Project description:To elucidate mechanisms governing McSC self-renewal and differentiation we analyzed individual transcriptomes from thousands of melanocyte lineage cells during the regeneration process. We identified transcriptional signatures for McSCs, deciphered transcriptional changes and intermediate cell states during regeneration, and analyzed cell-cell signaling changes to discover mechanisms governing melanocyte regeneration.

A dataset of single-cell transcriptomic atlas of Bama pigs and potential marker genes across seven tissues

Project description:The use of single-cell sequencing technology for single-cell transcriptomics studies in pigs is expanding progressively. However, the comprehensive classification of cell types across different anatomical tissues and organs of pigs in multiple datasets remains relatively limited. This study centers on an investigation using single-cell sequencing technology in Bama pigs, where unique marker genes and their corresponding transcriptomic profiles have been identified for diverse cell types across distinct anatomical tissues and organs, encompassing subcutaneous fat, visceral fat, skeletal muscle, liver, spleen, lung, and kidney. Using comprehensive data analyses, we discovered the widespread cellular diversity inherent in different anatomical tissues and organs of Bama pigs. This study not only provides a pivotal dataset for physiological research on Bama pigs but also contributes to the verification and prediction of key marker genes in the single-cell transcriptomics of these tissues and organs. Furthermore, the data and methodologies that were used in this study underscore our commitment to enhancing the authenticity of cell type identification and ensuring the consistency in cell type allocation.

Comparative anterior pituitary miRNA and mRNA expression profiles of Bama minipigs and Landrace pigs reveal potential molecular network involved in animal postnatal growth [miRNA array]

Project description:The anterior pituitary is the most important endocrine organ modulating animal postnatal growth, mainly by controlling growth hormone (GH) gene transcription, synthesis, and secretion. As an ideal model for animal postnatal growth studies, the Bama minipig is characterized as having a lower growth performance and fewer individual differences compared with larger pig breeds. In this study, anterior pituitaries from Bama minipig and Landrace pig were used for miRNA and mRNA expression profile analysis using miRNA microarrays and mRNA-seq. Consequently, a total of 222 miRNAs and 12,909 transcripts were detected, and both miRNAs and mRNAs in the two breeds showed high correlation (r > 0.97). Additionally, 41 differentially expressed miRNAs and 2,254 transcripts were identified. Pathways analysis indicated that 32 pathways significantly differed in the two breeds. Importantly, two GH-regulation-signalling pathways, cAMP and inositol 1, 4, 5-triphosphate (IP3), and multiple GH-secretion-related transcripts were significantly down-regulated in Bama minipigs. Moreover, target prediction by two algorithms (TargetScan and RNAhybrid) indicated that most miRNA–mRNA target pairs (63.68–71.33%) presented a negatively correlated expression pattern. A possible network among miRNAs, mRNAs, and GH-regulation pathways was also proposed. These data will be helpful in understanding the possible molecular mechanisms involved in animal postnatal growth. 2 pooled samples were analyzed. A pool of 3 pig anterior pituitary was used for Bama minpigs and Landrace pigs,respectively.
