Selenium, diabetes, and their intricate sex-specific relationship

Trends Endocrinol Metab. 2024 Apr 10:S1043-2760(24)00066-3. doi: 10.1016/j.tem.2024.03.004. Online ahead of print.ABSTRACTSelenium (Se) is an essential trace element, which is inserted as selenocysteine (Sec) into selenoproteins during biosynthesis, orchestrating their expression and activity. Se is associated with both beneficial and detrimental health effects; deficient supply or uncontrolled supplementation raises concerns. In particular, Se was associated with an increased incidence of type 2 diabetes (T2D) in a secondary analysis of a randomized controlled trial (RCT). In this review, we discuss the intricate relationship between Se and diabetes and the limitations of the available clinical and experimental studies. Recent evidence points to sexual dimorphism and an association of Se deficiency with gestational diabetes mellitus (GDM). We highlight the emerging evidence linking high Se status with improved prognosis in patients with T2D and lower risk of macrovascular complications.PMID:38599899 | DOI:10.1016/j.tem.2024.03.004
