Abstract
Sucrose emerges as a chelating agent to form a stable sucrose‐metal‐ion chelate that can potentially improve metal‐ion absorption. This study aimed to analyze the structure of sucrose‐calcium chelate and its potential to promote calcium absorption in both Caco‐2 monolayer cells and mice. The characterization results showed that calcium ions mainly chelated with hydroxyl groups in sucrose...
Skp2 plays multiple roles in malignant tumours. Here, we revealed that Skp2 negatively regulates type‐I interferon (IFN‐I)‐mediated antiviral activity. We first noticed that Skp2 can promote virus infection in cells. Further studies demonstrated that Skp2 interacts with IFN‐I receptor 2 (IFNAR2) and promotes K48‐linked polyubiquitination of IFNAR2, which accelerates the degradation of IFNAR2 proteins...
