Effects of Altering Freshwater Chemistry on Physiological Responses of Rainbow Trout to Silver Exposure [PDF]

, 1999
The influence of different water Cl- (50–600 μM), Ca2+ (50–1,500 μM), Na+ (50–1,500 μM), or dissolved organic carbon (DOC, 0.31–5 mg/L) levels on silver-induced physiological and biochemical perturbations of rainbow trout were investigated.

Copper in cancer: friend or foe? Metabolism, dysregulation, and therapeutic opportunities

Cancer Communications, Volume 45, Issue 5, Page 577-607, May 2025.
Abstract Copper, one of the essential nutrients for the human body, acts as an electron relay in multiple pathways due to its redox properties. Both deficiencies and excesses of copper lead to cellular fragility. Therefore, it can manifest pro‐ and anti‐cancer properties in tumors. Therefore, it is crucial to clarify the copper activity within the cell.

Coordination of SLC39A1 and DRP1 facilitates HCC recurrence by impairing mitochondrial quality control

Clinical and Translational Medicine, Volume 15, Issue 5, May 2025.
Abstract Background Despite rapid advances in HCC therapy, surgical resection is still the most effective treatment. However, postoperative relapse develops in a large population and the mechanism remains to be explored. Methods HCC resection samples were retrospectively collected from 12 nonrelapsed and 15 relapsed HCC patients for RNA sequencing ...
