Abstract
In this study, endoplasmic reticulum (ER) stress inducer tunicamycin (TM) and inhibitor 4-phenylbutyric acid (4-PBA) were used to treat postmortem chicken breast muscle to investigate changes in tenderness and effects on apoptosis and autophagy during 5 days ageing. TM-induced ER stress reduced shear force, enhanced myofibril fragmentation index (MFI), disrupted myofibril structure, increased desmin degradation, and activated μ-calpain and caspase-12. In addition, TM-induced ER stress increased the expression of Bax, Bim, and cytochrome c, and decreased the expression of Bcl-xL. Furthermore, TM-induced ER stress improved the conversion of LC3I to LC3II, raised the expression of Beclin-1, and decreased the expression of p62, PI3K, and mTOR. The opposite results were observed after 4-PBA treatment. These results suggested that ER stress could improve chicken tenderness, promote apoptosis and autophagy during chicken postmortem ageing.
期刊介绍:
Food Science and Human Wellness is an international peer-reviewed journal that provides a forum for the dissemination of the latest scientific results in food science, nutriology, immunology and cross-field research. Articles must present information that is novel, has high impact and interest, and is of high scientific quality. By their effort, it has been developed to promote the public awareness on diet, advocate healthy diet, reduce the harm caused by unreasonable dietary habit, and directs healthy food development for food industrial producers.
