Symposium: Nutrition, Biochemistry and Molecular Biology of Biotin Cellular Uptake of Biotin: Mechanisms and Regulation
This review describes our knowledge of biotin transport in the small intestine of humans and other mammals and presents recent findings in the area. Previous studies have shown that biotin transport across the brush border membrane of the small intestinal absorptive cells occurs via a carrier-mediated, Na gradientdependent, electroneutral mechanism. Exit of biotin out of the enterocyte, i.e., t...
متن کاملSalmonella infection inhibits intestinal biotin transport: cellular and molecular mechanisms.
Infection with the nontyphoidal Salmonella is a common cause of food-borne disease that leads to acute gastroenteritis/diarrhea. Severe/prolonged cases of Salmonella infection could also impact host nutritional status, but little is known about its effect on intestinal absorption of vitamins, including biotin. We examined the effect of Salmonella enterica serovar Typhimurium (S. typhimurium) in...
متن کاملMechanisms of quantum dot nanoparticle cellular uptake.
Due to the superior photoemission and photostability characteristics, quantum dots (QD) are novel tools in biological and medical applications. However, the toxicity and mechanism of QD uptake are poorly understood. QD nanoparticles with an emission wavelength of 655 nm are ellipsoid in shape and consist of a cadmium/selenide core with a zinc sulfide shell. We have shown that QD with a carboxyl...

متن کاملDifferentiation-dependent up-regulation of intestinal thiamin uptake: cellular and molecular mechanisms.
Differentiation of intestinal epithelial cells is associated with up-and-down regulation of expression of a variety of genes including those involved in nutrient uptake. Nothing is known about possible differentiation-dependent regulation of the intestinal thiamin uptake process and the cellular and molecular mechanisms involved in such regulation. Using as models human-derived intestinal epith...
