In children being treated for Pb poisoning by EDTA chelation therapy, elevated urinary ALA was significantly associated with higher chelatable Pb and with a decrease in the chelatable Zn/Pb ratio to 18.45 or less (115).
It was also important to verify the lack of increased excretion of essential trace elements, such as copper and zinc, and to determine the size of the chelatable pool of lead in nonoccupationally exposed adults.
The concentrations of chelatable NTBI showed variations in comparison with the bleomycin-detectable NTBI concentrations, with higher NTBI concentrations measured by the chelation assay.
Regulation of expression occurs by means of an interaction between the iron regulatory protein, a molecule that senses changes in the chelatable intracellular iron pool (27-29), and iron-responsive elements located on untranslated regions of ferritin and TfR mRNAs (30, 31).
Posttranscriptional regulation occurs by means of an interaction between IRPs, proteins that sense changes in the chelatable intracellular iron pool, and iron-responsive elements located on untranslated regions of transferrin receptor mRNA and ferritin mRNA (12-14).
The literature on the health effects of lead exposure also includes studies that have measured chelatable lead burden.
This regulation occurs by means of an interaction between the iron regulatory protein (IRP)', a molecule that senses changes in the chelatable intracellular iron pool X14-16], and iron-responsive elements (IREs) located on untranslated regions of ferritin and transferrin receptor mRNAs X16-18].
