Project description:The skeletal muscle development in swine begins at embryogenesis. Simultaneously, 24,123 probe-sets were screened, analysed for differential expression between different breeds (german landrace and pietrain) at different stages of development (35, 63, 91 dpc and adult stage). RNAs of skeletal muscle from german landrace and pietrain at 35, 63, 91 dpc and adult stages were hybridized to Affymetrix GeneChip Porcine Genome Array.

Project description:Muscle development and growth is an economically important process in the pig.The neonatal period is another important stage for the pig when the most rapid gain occurring in skeletal muscle.Gene expresseion changes during fetal and postnatal skeletal muscle development that can be used to enhance pig production efficiency, as well as for comparative developmental biology using the pig as a model for other mammalian species. We used microarrays to detail the global programme of gene expression level at different stages of postnatal development. Pig skeletal muscles were selected at different stages of post-natal development for RNA extraction and hybridization on Affymetrix microarrays.So,we sampled at four time-points: within 24 hours after birth (0d),7 days after birth (7d), 14 days after birth (14d), 21 days after birth (21d).

Project description:We have used RNA-seq to examine circular RNAs from RNase R treated and ribo- RNAs in chicken leg muscle of three different development stages (11 embryo age, 16 embryo age, and 1 days post hatch). Our study reveals the prevalence of circRNAs in chicken, and has identified circRNAs differentially abundant in different stage of embryonic skeletal muscle, suggesting its important functions during poultry muscle development.
Project description:The skeletal muscle growth and development is a very complicated but precisely regulated process with interwoven molecular mechanisms. Skeletal muscle is a very heterogeneous tissue that is made up of a large variety of functionally diverse fiber types. Muscle mass is therefore largely determined by the number and size of those fibres. These fibre characteristics are determined by hyperplasia before birth and by hypertrophy after. Around 65 dpc and three postnatal stages (newborn, 3 days; young, 60 days; and mature, 120 days) are key time points in swine skeletal muscle growth and development. We used microarrays to detail the global programme of gene expression underlying porcine skeletal muscle growth and development. Porcine longissimus dorsi muscles were selected at four stages of development for RNA extraction and hybridization on Affymetrix microarrays. We sought to investigate the global gene expression patterns accompanying the skeletal muscle development. To that end, we selected longissimus dorsi muscles at four time-points: 65 days post coitus, 3 days, 60 days and 120 days afterbirth.
