Project description:To investigate food safety made from genetically modified organisms and genome editing organism, we researched the difference of the metabolic substances between wild type and transformant in chicken blood by using transcriptome, proteome and metabolome analysis. In this study, we compared the difference of gene expression between wild type and GFP hetero transformant in leukocyte extracted from 1-2 month old female chickens.
Project description:To investigate food safety made from genetically modified organisms and genome editing organism, we researched the difference of the metabolic substances between wild type and transformant in chicken blood by using transcriptome, proteome and metabolome analysis. In this study, for the first basic research, we compared the difference of gene expression by sexual difference in leukocyte extracted from 1-2 month old wild type chickens.
Project description:Domestic chicken has been intensively studied because of its role as an efficient source of lean meat. However, commercial broilers resulting from genetic selection for rapid growth demonstrate detrimental traits, such as excess deposition of abdominal adipose tissue, metabolic disorders, and reduced reproduction. Therefore fast-growing broilers represent “obese” chickens compared to slow-growing egg layers (e.g, Leghorn) or wild strain of meat-type chickens (e.g., Fayoumi). Fayoumi chickens, originating from Egypt, represent a harder stain of chickens, which are more resistant to diseases. Leghorn chickens are the original breed of commercial U.S layers. Both lines were maintained highly inbred by Iowa State University poultry geneticists with an inbreeding coefficient higher than 0.95. Both Fayoumi and Leghorn demonstrated lean phenotype compared to broilers, and these three lines of chickens are genetically distant from each other. In this study, we used affymetrix microarray to profile global gene expression of three distinct genetic lines of chickens to identify functional pathways associated with leanness of domestic chickens.
Project description:Excessive Ang II signaling through AT1R is shown to cause pathological hypertrophy. Underlying molecular mechanisms are not yet known and expression studies are not available so far. To understand hAT1R signaling, cardiac tissue, from C57BL/6 mouse over expressing hAT1R signaling, is subjected to genomic microarray studies. This data compared with the data from healthy, non transgenic C57BL/6 mouse. Keywords: disease state analysis
