Selenium Innovation Lab

Selenium Innovation Lab

Overview

Selenium is an essential trace element for humans and animals, but not for plants. Hence, the current research is mainly focused on molecular biology, biochemistry, and nutrition, and there is still insufficient attention to plant nutrition, soil science, biogeochemistry, ecology, and society. In fact, selenium not only plays an important role in maintaining human and animal health but also has important potential health effects on soil health, rhizosphere health, plant health, gut health, ecological health, and even societal issues. With the help of the concept of “One Health” in the field of epidemiology and public health (definition: human health is closely related to animal health and environmental health, and should be systematically studied and treated under the same health framework, which cannot be separated, especially in the aspects of zoonotic pathogens, antibiotic resistance, pathogen carriers, etc.), it is promising to study the “One Health” perspective on Se in the future. Therefore, Selenium Innovation Laboratory (XILab) was established in Xi’an Jiaotong-Liverpool University (XJTLU) since 2023, to focus on “One Health on Selenium: From Soil to Gut”, which involved soil health via Se antagonism with heavy metals (Cd, As, Hg, Pb, Sb), rhizosphere health via Se benefits on microbiome, and gut health via Se intakes.

The XILab encourages industry-university-research cooperation and interdepartmental collaboration. It contributes to scientific research, teaching and industry in corresponding fields.

Research areas

  • Interactions between Se and toxic substances (eg. Cd, Hg, As, Pb, Sb, micro-/nano-plastics, antibiotics)
  • Roles of environmental microbiome on Se accumulation and transformation
  • Health effect assessment (eg. gut health) on various Se sources

Director

Dr Linxi Yuan was appointed as Senior Associate Professor at the Department of Health and Environmental Sciences at Xi’an Jiaotong-Liverpool University, and has an honorary appointment from the University of Liverpool. He has written two books, published two chapters, and edited two special issues on selenium biofortification. He has published a total of 105 peer-reviewed scientific papers. Now he served as Concil Member of International Society for Selenium Research, Founder of China Youth Branch of International Society for Selenium Research and Member of Sub-committee on F, As and Se, China Association of Endemic Diseases.
