Insulin receptor substrates (IRS-1 and IRS-2) are essential for intracellular signaling by insulin and insulin-like growth factor-I (IGF-I), anabolic regulators of bone metabolism. Although mice lacking the IRS-2 gene (IRS-2-/- mice) developed normally, they exhibited osteopenia with decreased bone formation and increased bone resorption. Cultured IRS-2-/-(More)
The adhesion of circulating cancer cells to the vascular endothelium is an important at step in the hematogenous metastasis of cancer. E-selectin expressed on endothelial cells and carbohydrate ligands expressed on cancer cells mediate this adhesion. We investigated the clinical significance of such cell adhesion molecules in breast cancer. The cytosol(More)
Our recent finding that ACTH increases c-fos mRNA in the adrenal gland of hypophysectomized rats indicates that the gene product FOS may play an important role(s) in mediating the action of ACTH. However, hypophysectomy employed in that study causes the disappearance of trophic hormones other than ACTH and may modify the effect of ACTH. Thus, in the present(More)
