Invariant NKT cells (iNKT cells) are innate T lymphocytes that are thought to play an important role in producing an early burst of IFN-γ that promotes successful tumor immunosurveillance and antimicrobial immunity. The cellular activation processes underlying innate IFN-γ production remain poorly understood. We show here that weak T cell receptor (TCR)(More)
Virtually all of the known biological actions of the hormonal ligand 1,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3)) are mediated by the vitamin D receptor (VDR). Following binding and activation by the ligand, the VDR localizes in the nucleus to the regulatory regions of target genes and recruits chromatin-active coregulatory complexes which, in turn,(More)
1,25-dihydroxyvitamin D3 (1,25(OH)2D3) functions as a steroid hormone to modulate the expression of genes. Its actions are mediated by the vitamin D receptor (VDR) which binds to target genes and functions to recruit coregulatory complexes that are essential for transcriptional modulation. ChIP analysis coupled to tiled DNA microarray hybridization(More)
Receptor activator of NF-κB ligand (Rankl) is a TNF-like factor that induces the formation of osteoclasts responsible for bone resorption. Although T cell activation up-regulates this gene, the molecular mechanism of its transcriptional control remains unknown. We used ChIP-chip analysis in mouse primary T cells and a T cell hybridoma to define the(More)
Soybean lipoxygenase-1 (SBLO-1) catalyzes the oxygenation of 1,4-dienes to produce conjugated diene hydroperoxides. The best substrates are anions of fatty acids; for example, linoleate is converted to 13(S)-hydroperoxy-9(Z),11(E)-octadecadienoate. The manner in which SBLO-1 binds substrates is uncertain. In the present work, it was found that SBLO-1 will(More)
Chronic inflammatory states are associated with increased bone loss. This increase is often linked to an elevation in receptor activator of nuclear factor-kappaB ligand (RANKL), a TNFalpha-like factor essential to osteoclast formation. In this study, we document the ability of IL-6 in combination with IL-6 soluble receptor (IL-6/IL-6sR) and oncostatin M to(More)
In this paper we present some of the algorithm improvements that have been made to Dragon's continuous speech recognition and training prograxns, improvements that have more than halved our error rate on the Resource Management task since the last SLS meeting in February 1991. We also report the "dry run" results that we have obtMned on the 5000-word(More)
Fat mass may be modulated by the number of brown-like adipocytes in white adipose tissue (WAT) in humans and rodents. Bone remodeling is dependent on systemic energy metabolism and, with age, bone remodeling becomes uncoupled and brown adipose tissue (BAT) function declines. To test the interaction between BAT and bone, we employed Misty (m/m) mice, which(More)
Progesterone (P4) stimulates proliferation of the mammary epithelium by a mechanism that involves paracrine signaling mediated from progesterone receptor (PR)-positive to neighboring PR-negative cells. Here we used a primary mouse mammary epithelial cell (MEC) culture system to define the molecular mechanism by which P4 regulates the expression of target(More)
Osteocytes are derived from osteoblast lineage cells that become progressively embedded in mineralized bone. Development of the osteocytogenic cell line IDG-SW3 has enabled a temporal and mechanistic investigation of this process. Through RNA-sequencing analyses, we show that although substantial changes in gene expression occur during the osteoblast to(More)
