(Submitter supplied) The dorsal and leg skin showed significant difference in skin thickness, feather follicle density and size.These traits are important characters of slaughtered chicken appearance. Global gene expression profiling was conducted in dorsal and leg skin of chickens, using the Agilent Chicken Gene Expression Chip. A total of 676 differentially expressed genes (DEGs) with at least 2-fold differences were identified (P < 0.05).GO analysis showed that DEGs were significantly involved in cell proliferation, differentiation, apoptotic, cell-cell adhesion and Wnt signaling pathway; KEGG pathway analyses found that DEGs were significantly mapped into ECM-receptor interaction, focal adhesion, Cell adhesion molecules (CAMs), regulation of actin cytoskeleton and Hedgehog signaling pathway.

The sample of 4 birds each from high and low RFI group from the whole lot of 225 broilers was taken for transcriptome analysis. The expression of genes influencing low and high feed efficiency and the pathways of these genes was studied out to examine the molecular mechanism influencing feed efficiency.

(Submitter supplied) Differentiation of B cells into antibody secreting cells (ASCs), plasmablasts and plasma cells, is regulated by a network of transcription factors. Within this network factors including PAX5 and BCL6 prevent ASC differentiation and maintain the B cell phenotype whereas BLIMP-1 and high IRF4 expression promote plasmacytic differentiation. BLIMP-1 is thought to induce immunoglobulin secretion. While IRF4 is needed for the survival of ASCs, its role in the regulation of antibody secretion has been controversial. more...

(Submitter supplied) In the modern chicken industry, fast-growing broilers have undergone strong artificial selection for muscle growth, which has led to remarkable phenotypic variations compared with slow-growing chickens. However, the molecular mechanism underlying these phenotypes differences remains unknown. In this study, a systematic identification of candidate genes and new pathways related to myofiber development and composition in chicken Soleus muscle has been made using gene expression profiles of two distinct breeds: Qingyuan partridge (QY), a slow-growing Chinese breed possessing high meat quality and Cobb 500 (CB), a commercial fast-growing broiler line. more...

(Submitter supplied) To find the possible molecular mechanism of myopia protection by violet light, we performed expression microarray analysis of chick chorioretinal tissue. The mRNA were obtained at day 13 from the following four groups: control eyes with or without violet light exposure and covered eyes with or without violet light exposure, and then the gene expression pattern was compared among them. Principle component analysis, which is to find major patterns of variability in gene expression, was performed and we found that the largest gene population (PC1, positive: n = 138, negative: n = 292) was affected by violet light treatment. more...
