Muscle transcriptional profiles of chickens from slow and fast growing lines with different degree of WS and WB myopathies

Project description:Broiler industry is facing an increasing prevalence of breast myopathies such as white striping (WS) and wooden breast (WB), whose precise etiology remains poorly understood. In order to progress in the understanding of the structural changes and the molecular pathways involved in these myopathies, and identify biomarkers, a transcriptomic analysis using an 8×60K Agilent chicken microarray was performed. The study used pectoralis major muscles from three groups: slow-growing animals (n=8), fast-growing animals visually free from defects (n=8) or severely affected by both WS and WB (n=8). In addition, a weighted correlation network analysis was performed to investigate the relationship between modules of co-expressed genes and histological traits.

Detection of differentially expressed genes in broiler Pectoralis major muscle affected by White Striping – Wooden Breast myopathies

Project description:White Striping and Wooden Breast (WS/WB) are abnormalities increasingly occurring in the fillets of high breast yield and growth rate chicken hybrids. These defects lead to consistent economic losses for poultry meat industry, as affected broilers fillets present an impaired visual appearance that negatively affects consumers’ acceptability. Previous studies have highlighted in affected fillets a deeply damaged muscle, showing profound inflammation, fibrosis and lipidosis. The present study investigated the differentially expressed genes and pathways linked to the compositional changes observed in WS/WB breast muscles, in order to outline a more complete framework of the gene networks related to the occurrence of this complex pathological picture. The biochemical composition was performed on 20 Pectoralis major samples obtained from high breast yield and growth rate broilers (10 affected vs. 10 normal) and 12 out of the 20 samples were used for the microarray gene expression profiling (6 affected vs. 6 normal). The obtained results indicate strong changes in muscle mineral composition, coupled to an increased deposition of fat. In addition, 204 differentially expressed genes (DEG) were found: 102 up-regulated and 102 down-regulated in affected breasts. The gene expression pathways found more altered in WS/WB muscles are those related to muscle development, polysaccharide metabolic processes, proteoglycans synthesis, inflammation and calcium signaling pathway. On the whole, the findings suggest that a multifactorial and complex etiology is associated with the occurrence of WS/WB muscle abnormalities, contributing to further define the transcription patterns associated to these myopathies.

Phenotypic and genotypic relationships between meat quality characteristics and expression of target genes associated with broiler meat quality defects

Project description:The objective of this project was to employ customized Agilent 8x60 chicken whole genome microarray to identify differentially expressed genes associated with white striping (WS) and wooden breast (WB) defects in breast meat collected from commercial broilers with different slaughter age. Following harvest of chicken breasts (n = 184), the breast samples were classified as based on their appearance into non-defect, WS or WB. The defective samples were further grouped based on defect severity (WS = mild, moderate, severe; WB = moderate, severe). A total numbers of 40 samples were selected to represent various degree of the defects. Total RNA from deep-frozen skeletal muscle was isolated, integrity check (RIN > 7.0) and subjected for one-colored microarray hybridization according to Agilent’s instruction. The array was designed (design ID: AMADID G4102A084792) based on the National Center for Biotechnology Information (NCBI) Gallus gallus Annotation Release 103 (https://www.ncbi.nlm.nih.gov/genome/annotation_euk/Gallus_gallus/103/). Differential gene expression (p-value < 0.05) was confirmed using qPCR and droplet digital PCR. Biological pathways associated with WS and WB were identified.
