Does chronic ketamine use increase serum levels of brain-derived neurotrophic factor?
These findings suggest that chronic ketamine intake is associated with increases in BDNF serum levels in humans. Other studies are needed to explore the pharmacological and molecular mechanism by which ketamine, and/or other NMDA antagonists, may induce modification in the production and utilization of BDNF and alter normal brain function.
The transporter Zip14 mediates hepatic uptake of zinc during liver regeneration and for hepatocyte proliferation. These findings indicate that zinc transporter activity regulates liver tissue growth by sequestering zinc. Reagents that regulate ZIP14 activity might be developed as therapeutics to promote liver regeneration in patients with chronic liver disease.
