Intestinal absorption of the cadmium cation by Jacqueline Louise Porter Download PDF EPUB FB2

The intestinal absorption of cadmium (Cd) increases when the body iron (Fe) stores are depleted. The depletion of Fe upregulates the expression of divalent metal transporter 1 (DMT1), which is located at the apical membrane of enterocytes lining the small intestine.

DMT1 has been shown to transport Fe and other divalent metal ions in by: Huebers HA, Huebers E, Csiba E, Rummel W, Finch CA. The cadmium effect on iron absorption. Am J Clin Nutr.

In this study we investigated the role of the apical Fe transporter divalent metal transporter 1 (DMT1) and the basolateral Fe exporter metal transporter protein 1 (MTP1) in Cd by: Sasser LB, Jarboe GE.

CdCl 2, or Cd complexed with cysteine or glutathione showed very similar absorption patterns, since Cd uptake by the intestinal epithelium was high (approximately to nmol after min) but the amount transferred (i.e. absorbed) was relatively low (approximately 7 Cited by: Chronic exposure to cadmium (Cd) causes remarkable damage to the liver and gastrointestinal tract.

However, even though MT involvement has been suggested, the cellular mechanism for how cadmium enhances its own absorption remains to be elucidated [ ]. Intestinal MT is induced by cadmium [ ], but there are. Purchase Nutrition, Digestion, Metabolism - 1st Edition.

Print Book & E-Book. ISBN  The site of cadmium and mercury retention in the intestine was determined in 6-day-old sucklings and 6-week-old weaned rats 6 days after oral administration of m Cd and Hg. The ileum was found to be the main site of intestinal retention of both cations in sucklings but not in weaned rats.

Also, cadmium in water is more easily absorbed than cadmium in food (5% in water versus % in food) (IRIS ). The presence of elevated zinc or chromium in the diet decreases cadmium uptake. Dermal. Absorption through the skin is not a significant route of cadmium entry; only about % of cadmium is absorbed by the skin (ATSDR ).

Intestinal absorption of cadmium (Cd) is considered to be mediated mainly by the ferrous iron transporter DMT1, or the calcium transporter CaT1. The roles of zinc transporters such as ZIP8 and ZIP14 remain unclear, and the roles of these four transporters in the intestinal uptake of Cd under physiological conditions have not been compared.

It is important for the operator to understand the .Thus particle size, which controls alveolar deposition, is a key determinant of cadmium absorption in the lung. In humans, figures of % of absorption rate according to particle size are derived for Cd dusts. For Cd fumes, based on cigarette smoke studies, it can be calculated that the respiratory absorption of Cd fumes is between 25% and 50%.
