The budding yeast Saccharomyces cerevisiae responds to depletion of iron in the environment by activating Aft1p, the major iron-dependent transcription factor, and by transcribing systems involved in the uptake of iron. Here, we have studied the transcriptional response to iron deprivation and have identified new Aft1p target genes. We find that other(More)
ortho-Substituted PCBs mobilize Ca2+ from isolated brain microsomes by interaction with FKBP12/RyR complexes. Investigation into the cellular importance of this mechanism was undertaken using PC12 cells by fluoroimaging the actions of specific PCB congeners on [Ca2+]i and pH. RyR and IP3R share a common intracellular Ca2+ store in PC12 cells. Perfusion of(More)
Addiction has been proposed to emerge from associations between the drug and the reward-associated contexts. This associative learning has a cellular correlate, as there are more cFos+ neurons in the hippocampal dentate gyrus (DG) after psychostimulant conditioned place preference (CPP) versus saline controls. However, it is unknown whether morphine CPP(More)
