Analysis of the immunoglobulin light chain genes in zebra finch: evolutionary implications.
All jawed vertebrates produce immunoglobulins (IGs) as a defense mechanism against pathogens. Typically, IGs are composed of two identical heavy chains (IGH) and two identical light chains (IGL). Most tetrapod species encode more than one isotype of light chains. Chicken is the only representative of birds for which genomic information is currently available and is an exception to the above rul...
متن کاملAntioxidant and immune gene expression in zebra fish (Danio rerio)
Iodine is the main ingredient produced by the thyroid hormone, which playa a central role in the metabolism and the immune system. The present study aims to evaluate the effects of feeding Artemia fransiscana enriched with potassium iodide on antioxidant and immune gene expression in zebra fish (Danio rerio). Zebra larvae with an average weight of 2±0.01 mg were randomly distributed into 4 trea...
متن کاملEvolution of a cluster of innate immune genes (β-defensins) along the ancestral lines of chicken and zebra finch
BACKGROUND Avian beta-defensins (AvBDs) represent a group of innate immune genes with broad antimicrobial activity. Within the chicken genome, previous work identified 14 AvBDs in a cluster on chromosome three. The release of a second bird genome, the zebra finch, allows us to study the comparative evolutionary history of these gene clusters between from two species that shared a common ancesto...
متن کاملSexually dimorphic neurocalcin expression in the developing zebra finch telencephalon.
Differential display RT-PCR was used on RNA isolated from the zebra finch telencephalon to identify gene products potentially involved in its development, including the sexually dimorphic nuclei responsible for song learning and production. A cDNA identified only in juvenile females was cloned and sequenced. It shares homology with neurocalcin, a calcium binding protein. Northern blots indicate...
متن کاملAnalysis of CR1 repeats in the zebra finch genome
Most bird species have smaller genomes and fewer repeats than mammals. Chicken Repeat 1 (CR1) repeat is one of the most abundant families of repeats, ranging from ~133,000 to ~187,000 copies accounting for ~50 to ~80% of the interspersed repeats in the zebra finch and chicken genomes, respectively. CR1 repeats are believed to have arisen from the retrotransposition of a small number of master e...
