Metal-containing compounds show promise as HIV weapon
... 31, 2005 A molecule consisting of two "cages" of metallic atoms bound to carbon has shown great promise in preliminary tests of becoming a new weapon in the anti-HIV arsenal, researchers at UT Southwestern Medical Center report. The molecule called metallacarborane and its variants appear to fight HIV pro...EPA-led group finds same protein that attracts nutrient iron protects lung from particles
...esting how "pre-conditioning" with various foreign metallic insults might affect gene expression and resulting lung damage. One key to how DMT1 works is by generating two alternatively spliced messenger RNAs that differ by the presence (+) or absence (-) of an Iron-Response Element (thus IRE or +IRE).
