Abstract
Sepsis is a life-threatening organ dysfunction caused by the dysregulated response of the host to an infection, and treatments are limited. Recently, a novel selenium source, selenium-enriched Cardamine violifolia (SEC) has attracted much attention due to its anti-inflammatory and antioxidant properties, but little is known about its role in the treatment of sepsis. Here, we found that SEC alleviated LPS-induced intestinal damage, as indicated by improved intestinal morphology, and increased disaccharidase activity and tight junction protein expression. Moreover, SEC ameliorated the LPS-induced release of pro-inflammatory cytokines, as indicated by decreased IL-6 level in the plasma and jejunum. Moreover, SEC improved intestinal antioxidant functions by regulating oxidative stress indicators and selenoproteins. In vitro, TNF-α-challenged IPEC-1 cells were examined and showed that selenium-enriched peptides, which are the main functional components extracted from Cardamine violifolia (CSP), increased cell viability, decreased lactate dehydrogenase activity and improved cell barrier function. Mechanistically, SEC ameliorated LPS/TNF-α-induced perturbations in mitochondrial dynamics in the jejunum and IPEC-1 cells. Moreover, CSP-mediated cell barrier function is primarily dependent on the mitochondrial fusion protein MFN2 but not MFN1. Taken together, these results indicate that SEC mitigates sepsis-induced intestinal injury, which is associated with modulating mitochondrial fusion.

Selenium deficiency-induced multiple tissue damage with dysregulation of immune and redox homeostasis in broiler chicks under heat stress. SCIENCE CHINA. LIFE SCIENCES 2023; 66:2056-2069.

Abstract
Broiler chicks are fast-growing and susceptible to dietary selenium (Se) deficiency. This study sought to reveal the underlying mechanisms of how Se deficiency induces key organ dysfunctions in broilers. Day-old male chicks (n=6 cages/diet, 6 chicks/cage) were fed with a Se-deficient diet (Se-Def, 0.047 mg Se/kg) or the Se-Def+0.3 mg Se/kg (Control, 0.345 mg Se/kg) for 6 weeks. The serum, liver, pancreas, spleen, heart, and pectoral muscle of the broilers were collected at week 6 to assay for Se concentration, histopathology, serum metabolome, and tissue transcriptome. Compared with the Control group, Se deficiency induced growth retardation and histopathological lesions and reduced Se concentration in the five organs. Integrated transcriptomics and metabolomics analysis revealed that dysregulation of immune and redox homeostasis related biological processes and pathways contributed to Se deficiency-induced multiple tissue damage in the broilers. Meanwhile, four metabolites in the serum, daidzein, epinephrine, L-aspartic acid and 5-hydroxyindoleacetic acid, interacted with differentially expressed genes with antioxidative effects and immunity among all the five organs, which contributed to the metabolic diseases induced by Se deficiency. Overall, this study systematically elucidated the underlying molecular mechanisms in the pathogenesis of Se deficiency-related diseases, which provides a better understanding of the significance of Se-mediated heath in animals.

Abstract
BACKGROUND & OBJECTIVE Selenium was one of the essential trace elements that played a pivotal role in human health. Although previous studies have investigated the relationship between selenium and non-alcoholic fatty liver disease (NAFLD) and fibrosis, these findings were still inconclusive. Our study was aimed to explore the association between blood selenium level and NAFLD and advanced liver fibrosis diagnosed by vibration controlled transient elastography (VCTE) in US adults. METHODS All data were extracted from National Health and Nutrition Examination Survey database (2017-2018). Participants were divided into four groups according to quartile of blood selenium level. Liver stiffness and controlled attenuation parameter (CAP) were measured by VCTE. Multiple logistic regression models and subgroup analyses were conducted to determine the association between blood selenium level and NAFLD and advanced liver fibrosis diagnosed by a variety of methods. RESULTS A total of 3336 participants were enrolled in main analysis. In multiple logistic regression models, the higher blood selenium level (>205.32, ≤453.62 μg/L) had a significant positive association with NAFLD (β = 1.31). Moreover, high blood selenium level had significantly inversely association to advanced liver fibrosis (β = 0.61). In subgroup analysis, the main inversely correlation between blood selenium and advanced liver fibrosis was found in males with high blood selenium level. Despite dietary selenium intake being adjusted or in different subgroups, the associations between blood selenium level and NAFLD/advanced liver fibrosis remained significant. CONCLUSIONS This study showed that blood selenium level were positively association with NAFLD among US population. Participants with lower blood selenium level showed a higher percentage of advanced liver fibrosis. Blood selenium is more likely to cause NAFLD and liver fibrosis due to imbalances in selenium homeostasis rather than dietary selenium intake.Key messagesHigh blood selenium level was association with NAFLD diagnosed by vibration controlled transient elastography.Participants with lower blood selenium level had high percentage of advanced liver fibrosis.NAFLD and liver fibrosis are caused by an imbalance of selenium homeostasis, not by dietary selenium intake.

Abstract
Selenium (Se) is an essential element for human health as it is involved in different physiological functions. Moreover, a great number of Se compounds can be considered potential agents in the prevention and treatment of some diseases. It is widely recognized that Se activity is related to multiple factors, such as its chemical form, dose, and its metabolism. The understanding of its complex biochemistry is necessary as it has been demonstrated that the metabolites of the Se molecules used to be the ones that exert the biological activity. Therefore, the aim of this review is to summarize the recent information about its most remarkable metabolites of acknowledged biological effects: hydrogen selenide (HSe−/H2Se) and methylselenol (CH3SeH). In addition, special attention is paid to the main seleno-containing precursors of these derivatives and their role in different pathologies.

Abstract
The importance of selenium (Se) in biology and health has become increasingly clear. Hydrogen selenide (H2Se), the biologically available and active form of Se, is suggested to be an emerging nitric oxide (NO)-like signaling molecule. Nevertheless, the research on H2Se chemical biology has technique difficulties due to the lack of well-characterized and controllable H2Se donors under physiological conditions, as well as a robust assay for direct H2Se quantification. Motivated by these needs, here, we demonstrate that selenocyclopropenones and selenoamides are tunable donor motifs that release H2Se upon reaction with cysteine (Cys) at pH 7.4 and that structural modifications enable the rate of Cys-mediated H2Se release to be tuned. We monitored the reaction pathways for the H2Se release and confirmed H2Se generation qualitatively using different methods. We further developed a quantitative assay for direct H2Se trapping and quantitation in an aqueous solution, which should also be operative for investigating future H2Se donor motifs. In addition, we demonstrate that arylselenoamide has the capability of Cys-mediated H2Se release in cellular environments. Importantly, mechanistic investigations and density functional theory (DFT) calculations illustrate the plausible pathways of Cys-activated H2Se release from arylselenoamides in detail, which may help understand the mechanistic issues of the H2S release from pharmacologically important arylthioamides. We anticipate that the well-defined chemistries of Cys-activated H2Se donor motifs will be useful for studying Se biology and for development of new H2Se donors and bioconjugate techniques.
