Selenomethionine alleviates kidney necroptosis and inflammation by restoring lipopolysaccharide-mediated mitochondrial dynamics imbalance via the TLR4/RIPK3/DRP1 signaling pathway in laying hens
Selenomethionine (SeMet) is a beneficial organic source of selenium that is extensively used as a food additive owing to its antioxidant and anti-inflammatory properties. Due to the sensitivity of the kidneys to noxious stimuli, they are more susceptible to various injuries. To investigate the protective mechanisms of SeMet supplementation against kidney injury, we established an in vivo experimental model using laying hens treated with SeMet (0.5 mg/kg diet) and/or lipopolysaccharide (LPS) (0.2 mg/kg. BW) and an in vitro model of chicken embryo primary kidney (CEK) cells treated with SeMet (0.075 mM) and with/ without LPS (60 μg/mL). SeMet treatment alleviated the LPS-induced kidney insufficiency and mitochondrial damage. Furthermore, it reduced the expression of TLR4, RIPK3, MLKL, DRP1, NLRP3, and IL-1β in the kidneys of laying hens. RIPK3 is known to induced necroptosis and inflammation by activating of the downstream factors DRP1 and MLKL. To investigate the mechanism whereby SeMet alleviates LPS-induced necroptosis in the kidney, we pretreated CEK cells with TLR4, RIPK3, and DRP1 inhibitors. The results demonstrated that RIPK3 inhibition resulted in a significantly increased in the mitochondrial membrane potential and downregulation of DRP1. Upon the inhibition of DRP1 expression, MLKL, NLRP3, and IL-1β expression also decreased. In summary, SeMet regulates the TLR4/RIPK3/DRP1 signaling pathway to restore the LPS-induced imbalances in mitochondrial dynamics, thereby alleviating necroptosis and inflammation in the kidneys of laying hen. Selenium also increases the expression of selenoproteins. This study provides valuable information for the development of new therapeutic strategies using SeMet to alleviate kidney injury.
期刊介绍:
First self-published in 1921, Poultry Science is an internationally renowned monthly journal, known as the authoritative source for a broad range of poultry information and high-caliber research. The journal plays a pivotal role in the dissemination of preeminent poultry-related knowledge across all disciplines. As of January 2020, Poultry Science will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers.
An international journal, Poultry Science publishes original papers, research notes, symposium papers, and reviews of basic science as applied to poultry. This authoritative source of poultry information is consistently ranked by ISI Impact Factor as one of the top 10 agriculture, dairy and animal science journals to deliver high-caliber research. Currently it is the highest-ranked (by Impact Factor and Eigenfactor) journal dedicated to publishing poultry research. Subject areas include breeding, genetics, education, production, management, environment, health, behavior, welfare, immunology, molecular biology, metabolism, nutrition, physiology, reproduction, processing, and products.
