Oyster shells water extract ameliorates propylthiouracil-induced goitre in rats via PI3K/AKT/Bcl-2 pathway.
Oysters are recognized for flavor and health benefits, but their shells are regarded as waste, contributing to resource inefficiency. This study investigates the chemical composition and pharmacological activity of oyster shells, using a fraction partitioning approach to separate the oyster shells water extract (WE) into two fractions: WE of extra-membranous (WEE, <1000 kDa) and intra-membranous (WEI, >1000 kDa). Using UPLC-Q-Exactive MS, 231 components were identified such as organic acids, amino acids. ELISA analysis revealed that high-dose WEE significantly increased serum T3, T4, FT3, and FT4 levels while reducing TSH, and improved thyroid tissue lesions. Network pharmacology identified 291 drug-disease intersection targets enriched in the PI3K/AKT pathway. Furthermore, the RT-qPCR and WB results showed that high-dose WEE protected against propylthiouracil-induced goitre by inhibiting the PI3K/AKT/Bcl-2 pathway. This study evaluated the anti-goitre potential properties of WE and provided a theoretical basis for further development of oyster shells as a functional food source.
期刊介绍：
npj Science of Food is an online-only and open access journal publishes high-quality, high-impact papers related to food safety, security, integrated production, processing and packaging, the changes and interactions of food components, and the influence on health and wellness properties of food. The journal will support fundamental studies that advance the science of food beyond the classic focus on processing, thereby addressing basic inquiries around food from the public and industry. It will also support research that might result in innovation of technologies and products that are public-friendly while promoting the United Nations sustainable development goals.
