TranscriptomicsTranscription profiling of liver, kidney and brain from male and female Zebra Finches
Each array hybridization involved one male sample hybridized in competition to one female sample. For each hybridization one sample was labeled with Cy5 and the other with Cy3. Half of the male samples were labeled with Cy5 and rest with Cy3. Each hybridization was tissue-specific (i.e., hybridiz...

TranscriptomicsMelospiza melodia hypothalamus: control and STI in two seasons (spring and autumn)
Male song sparrows (Melospiza melodia) are territorial year-round; however, neuroendocrine responses to simulated territorial intrusion (STI) differ between breeding (spring) and non-breeding seasons (autumn). In spring, exposure to STI leads to increases in luteinizing hormone and testosterone, bu...

TranscriptomicsBirdsong "Transcriptomics": Neurochemical Specializations of the Oscine Song System
Background: Vocal learning is a rare and complex behavioral trait that serves as a basis for the acquisition of human spoken language. In songbirds, vocal learning and production depend on a set of specialized brain nuclei known as the song system. Methodology/Principal Findings: Using high-throughp...

TranscriptomicsTranscription profiling of chicken male and female embryonic hearts (arnol-affy-chick-445639)
The study is relevant to an understanding of the forces that lead to sex differences in the brain and other somatic tissues. Many neural and psychiatric diseases affect men and women differently, so the understanding of sex differences in brain function impacts on our understanding of why the male a...

TranscriptomicsSex bias and dosage compensation in the zebra finch versus chicken genomes: general and specialized patterns among birds
We have performed a comparison of global patterns of gene expression between two bird species, the chicken and zebra finch, especially with regard to sex bias of autosomal vs. Z chromosome genes, dosage compensation and evolution of sex bias. Both species appear to lack a Z chromosome-wide mechanism...

TranscriptomicsThe impact of experience-dependent and independent factors on gene expression in songbird brain [e14]
Songbirds provide rich natural models for studying the relationships of brain anatomy, behavioral function, environmental signals and gene expression. Under the Songbird Neurogenomics Initiative, investigators from more than a dozen laboratories collected brain samples from six species of songbird ...
