Project description:Excessive accumulation of lipids in the adipose tissue is a major problem in the present-day broiler industry. However, few studies have analyzed the expression of adipose tissue genes that are involved in pathways and mechanisms leading to adiposity in chickens. Gene expression profiling of chicken adipose tissue could provide key information about the ontogenesis of fatness and clarify the molecular mechanisms underlying obesity. Chicken Genome Arrays were used to construct an adipose tissue gene expression profile of 7-week-old broilers, and to screen adipose tissue genes that are differentially expressed in lean and fat lines divergently selected over eight generations for high and low abdominal fat weight. Keywords: two lines comparison

Experiment Overall Design: Birds were slaughtered at 7 weeks and abdominal fat was isolated, immediately frozen in liquid nitrogen and stored at -80oC. The ten birds used in the present study were chosen by the percentage of abdominal fat (AFP): five had the highest AFP and the other five had the lowest for RNA extraction and hybridization on Affymetrix microarrays..

Project description:Chickens divergently selected for either high growth (HG genotype) or low growth (LG genotype) at SRA-INRA, France were used to profile abdominal adipose gene expression at 7 wk of age. The HG and LG chickens are different in various phenotypic and metabolic measurements, including growth rate, abdominal fat, plasma glycemia, insulinemia, T4, T3, triglyceride and NEFA. The HG and LG chickens are valuable as a model for biomedical and agricultural traits. Massively parallel RNA sequencing (RNA-Seq) was completed on an Illumina HiSeq 2000 System for transcription analysis of HG and LG abdominal fat. Need information on data processing, statistical analysis, and differential expression. Keywords: abdominal fat, divergently selected chickens, growth, transcriptional profiling, differentially expressed genes

Project description:Chickens divergently selected for either high growth (HG genotype) or low growth (LG genotype) by F.H. Ricard at SRA-INRA, Nouzilly France were used for time-course transcriptional profiling of abdominal fat during juvenile development (1 to 11 weeks of age) to identify differentially expressed genes. The HG and LG chickens are different in various phenotypic and metabolic measurements, including growth rate, abdominal fat, plasma glycemia, insulinemia, T4, T3, triglyceride and NEFA. Thus, the HG and LG chickens are valuable as a model for biomedical and agricultural traits. The Del-Mar 14K Chicken Integrated Systems microarrays were used for a transcriptional scan in abdominal adipose during juvenile development using a balanced block hybridization design. Log2-transformed fluorescence intensities were analyzed with the linear mixed model (MIXED) procedure in SAS (SAS Institute Inc., Cary, NC, USA). A total of 3,957 differentially expressed functional genes were identified (FDR<0.05) as having a significant effect of age (2,918), genotype (312), or an age by genotype interaction (727). The differentially expressed genes include adipokines, metabolic enzymes, acute phase proteins, growth factors, coagulation factors, immune factors and transcription factors involved in various pathways. Keywords: abdominal fat, divergently selected chickens, growth, transcriptional profiling, differentially expressed genes, lipogenesis

Keywords: abdominal fat, divergently selected chickens, growth, transcriptional profiling, differentially expressed genes, lipogenesis A balanced block design was used for microarray hybridizations, where half of the birds of each genotype and age were labeled with Alexa Flour 647 (red) and the other half with Alexa Flour 555 (green). Four biological replicates were used for each genotype (HG or LG) at six different ages (1, 3, 5, 7, 9 and 11 wk).
