Phosphoenolpyruvate carboxykinase (PEPCK) is a key regulatory enzyme of gluconeogenesis. Genetic variations in this gene may therefore affect a wide variety of traits, including tumor growth that is heavily dependent on glucose metabolism. We have previously shown the gene coding for the mitochondrial form of PEPCK (PEPCK-M) segregates for markers that are(More)
Sequence analysis of 4,230 bp of the 3' end of the ornithine decarboxylase gene of 20 chickens from a noninbred White Leghorn strain revealed a total of 62 polymorphisms. Of these 61% were transitions, 24% were transversions, and 16% were deletions or insertions. Despite the high number of polymorphisms, only 3 haplotypes were present among the 40 alleles(More)
White Leghorn chickens from a nonselected closed population were typed for two RFLP located in the 3' end of the gene coding for cytosolic phosphoenol-pyruvate carboxykinase (PEPCK-C), a major control gene of gluconeogenesis. The two RFLP gave rise to three alleles (or haplotype classes), thus defining six genotypes. Feed efficiency (FE) and residual feed(More)
The integrity of an organism is maintained by networks of interacting genes. Such networks predict that genetic variants affect phenotypes in a nonadditive fashion. That is, the effect of an allelic variation in one gene is dependent on the variations in other genes. We summarize the analyses of a series of genes in a White Leghorn strain that support the(More)
