Transcriptome Analysis Reveals Potential Mechanisms Underlying Differential Heart Development In Fast- And Slow-Growing Broilers Under Heat Stress, Jibin Zhang, Carl J. Schmidt, Susan J. Lamont

Background
Modern fast-growing broilers are susceptible to heart failure under heat stress because their relatively small hearts cannot meet increased need of blood pumping. To improve the cardiac tolerance to heat stress in modern broilers through breeding, we need to find the important genes and pathways that contribute to imbalanced cardiac development and frequent occurrence of heat-related heart dysfunction. Two broiler lines – Ross 708 and Illinois – were included in this study as a fast-growing model and a slow-growing model respectively. Each broiler line was separated to two groups at 21 days posthatch. One group was subjected to heat stress …

Velogenic Newcastle disease virus (NDV) causes global economic losses in the poultry industry. Although proper vaccination does prevent outbreaks of ND, genetic selection for enhanced resistance to NDV offers a complementary approach to disease prevention. Understanding the gene expression changes induced by ND infection will help to elucidate mechanisms of host resistance and susceptibility.
Two distinct and highly inbred chicken lines - Fayoumi and Leghorn - were studied as relatively ND-resistant and susceptible models, respectively. Equal numbers of birds from each line were inoculated with LaSota strain NDV (or saline control) through nasal and ocular routes at 21 days of …
