Iron uptake and regulation in Schizosaccharomyces pombe.

abstract：:The ability to control uptake across the mucosa and to protect the gut from harmful substances present in the lumen is defined as intestinal barrier function. Two routes are usually distinguished for transepithelial transport. The paracellular route allows the passage of ions and small molecules and is mainly regulate...
