Project description:The unique fat storage and metabolic characteristics of goose liver is an important model for studying lipid metabolism in animals or humans. In this study, RNA sequencing technology was used to obtain the liver transcriptome of Sichuan white goose with significant weight difference in the same population, and differentially expressed genes and their pathways were identified, which may help to understand the mechanism of goose weight change. In addition, the identified candidate genes may be useful for molecular breeding of geese.

Project description:Lion-head goose is the only large goose species in China, and it was one of the largest goose species in the world. Our previous study firstly reported a chromosome-level genome assembly of Lion-head goose (Anser cygnoides), a native breed in South China, through the combination of PacBio, Bionano, and Hi-C technologies. The fat content of foie gras is augmented during its preparation due to the special feeding regimen. Lion-head geese have a strong tolerance of massive energy intake and show a priority of fat accumulation in liver tissue. In this study, we studied for the first time the important differential genes that regulate fatty liver in Lion-head goose. After high-intake feeding, the fatty livers of Lion-head geese were distinctly characterized. The revelation of gene regulation is an important basis for the study of liver development and molecular characteristics for the Lion-head goose. To analyze the excellent fatty liver performance of Lion-head goose at the molecular level, we performed whole transcriptome analysis by high-throughput RNA sequencing to analyze the key regulatory genes that determine the fatty livers in high-intake feeding group compared with the normal livers in normally-fed Lion-head geese. We identified 716 differentially expressed mRNAs, 145 differentially expressed circRNAs, and 39 differentially expressed lncRNAs in the fatty livers in high-intake feeding group compared with the normal livers in normally-fed Lion-head geese, including upregulated and downregulated genes, respectively. GO enrichment analysis showed that these genes were significantly enriched in molecular function, involved in extracellular regions, DNA-binding transcription factor activity, extracellular matrix, heme binding and other life activities. We chose differentially expressed genes involved in either upregulation or downregulation, and we additionally confirmed the accuracy of sequencing at the RNA level. In summary, our research suggested that these differentially expressed genes may play important roles in fatty liver development in Lion-head goose. However, the functions and mechanisms of these significantly differentially expressed genes should be investigated in future studies.

Project description:Purpose: Recent development in high-throughput sequencing techniques (RNA-seq) has enabled large scale analysis of genetic variations and gene expression in different tissues and species, but gene expression patterns and genetic variations in livestock have not yet been well characterized. In this study we have used high-throughput transcriptomic sequencing of the Finnish Yorkshire to identify gene expression patterns within the breed in the testis and oviduct. Methods: The Solid 4 reads were mapped against the pig genome build 10.2 using the colorspace alignment tool provided by Applied Biosystems and distributed with the instrument (LifeScope v2.1). Reads associated with ribosomal RNA, transfer RNA, repeats and other uninformative reads were filtered out during the process as well as reads with more than 10 potential alignments. After alignment to the reference genome, low mapping quality reads were discarded (mapQV(<10)) and unique reads were associated with known genes based on UCSC annotations, and the number of reads aligned within each gene was counted. FPKM values were calculated for normalization of the data to remove variation between samples caused by non-biological reasons using the Cufflinks software v2.0.2. Results: The analysis of gene expression differences between the testis and oviduct highlighted 1,234 genes up-regulated in the testis and 1,501 in the oviduct. Conclusions: The RNA-seq technology used in this study provides novel information about transcript expression and differential gene expression in the testis and oviduct. The produced data will assist in the identification of candidate genes based on association mapping results within the pig population and provides insights into the expression of genes in the two reproductive organs studied. Testis and oviduct mRNA profiles of adult WT and immotile short tail sperm (ISTS) affected Finnish Large White pigs were generated by deep sequencing using Solid 4 platform.

Project description:Geese have a high tolerance of massive energy intake and exhibit little pathological development. We assessed phenotypes and transcriptomes of Tianfu geese to investigate the dynamic expression network behind goose adipogenesis. Goose liver exhibited higher fat accumulation than adipose tissues during fattening. We identified differentially expressed genes that function in several important lipid metabolism pathways, immune response, regulation of cancer, and differentially expressed long noncoding RNAs that might be involved in regulation of these pathways. We found that genes like BGE1 and SCD, which have key roles in glycolysis and synthesis of fatty acids, had higher fold change in liver than in adipose tissue. we suppose that the evolutionary split from mammals in adipogenesis is a result of adaptive evolution to long-distance migration.

Project description:The underlying genomic regulation of the tissue synchronization is poorly understood. To understand this better we investigated the transcriptomes of the porcine ovary, endometrium, and oviduct at days 0, 3, 6, 9, 12, 15, or 18 of the oestrous cycle. We analysed the transcriptome profiles of the individual tissues.

Project description:Predators attack conspicuous prey phenotypes that are present in the environment. Male display behavior of conspicuous nuptial coloration becomes risky in the presence of a predator, and adult males face higher predation risk. High predation risk in one sex will lead to low survival and sex ratio bias in adult cohorts, unless the increased predation risk is compensated by higher escape rate.Here, we tested the hypothesis that sand lizards (Lacerta agilis) have sex-specific predation risk and escape rate. We expected the differences to manifest in changes in sex ratio with age, differences in frequency of tail autotomy, and in sex-specific survival rate.We developed a statistical model to estimate predation risk and escape rate, combining the observed sex ratio and frequency of tail autotomy with likelihood-based survival rate. Using Bayesian framework, we estimated the model parameters. We projected the date of the tail autotomy events from growth rates derived from capture-recapture data measurements.We found statistically stable sex ratio in age groups, equal frequency of tail regenerates between sexes, and similar survival rate. Predation risk is similar between sexes, and escape rate increases survival by about 5%. We found low survival rate and a low number of tail autotomy events in females during months when sand lizards mate and lay eggs, indicating high predator pressure throughout reproduction. Our data show that gravid females fail to escape predation.The risks of reproduction season in an ectotherm are a convolution of morphological changes (conspicuous coloration in males and body allometry changes in gravid females), behavior (nuptial displays), and environmental conditions which challenge lizard thermal performance. Performance of endotherm predators in cold spring months endangers gravid females more than displaying males in bright nuptial coloration.
