The effects of treatment with bis(maltolato)oxovanadium(IV) (BMOV) on protein localization in membrane microdomains were investigated by comparing the effects of insulin and treatment with BMOV on the lateral motions and compartmentalization of individual insulin receptors (IR). In addition, effects of insulin and BMOV on the association of IR,(More)
We have examined the association of insulin receptors (IR) and downstream signaling molecules with membrane microdomains in rat basophilic leukemia (RBL-2H3) cells following treatment with insulin or tris(2-pyridinecarbxylato)chromium(III) (Cr(pic)3). Single-particle tracking demonstrated that individual IR on these cells exhibited reduced lateral diffusion(More)
Vanadium oxides (VOs) have been identified as low molecular weight sensitizing agents associated with occupational asthma and compromised pulmonary immunocompetence. Symptoms of adult onset asthma result, in part, from increased signal transduction by Type I Fcε receptors (FcεRI) leading to release of vasoactive compounds including histamine from mast(More)
