TIS10 is a primary response gene whose cDNA was cloned as a result of its rapid, superinducible expression in Swiss 3T3 cells in response to 12-O-Tetradecanoylphorbol-13-acetate. The 5'-untranslated region of the 3.9-kilobase TIS10 message contains only 124 nucleotides, whereas the 3'-untranslated region is almost 2 kilobases in length. Within this long 3'(More)
Conventional nonsteroidal anti-inflammatory drugs inhibit both cyclooxygenase (Cox) isoforms (Cox-1 and Cox-2) and may be associated with nephrotoxicity. The present study was undertaken to assess the renal effects of the specific Cox-2 inhibitor, MK-966. Healthy older adults (n = 36) were admitted to a clinical research unit, placed on a fixed sodium(More)
Vitamin D has been suggested to have an effect on erythropoiesis. We sought to evaluate the prevalence of anemia in a population of individuals with vitamin D deficiency compared with those with normal levels in a population of a large integrated healthplan. A cross-sectional analysis in the period 1 January 2004 through 31 December 2006 of subjects with(More)
BACKGROUND Diabetic nephropathy is the leading cause of end-stage renal disease in the USA, yet most patients with type 2 diabetes mellitus are not formally evaluated with a renal biopsy. Our aim was to evaluate the prevalence of nondiabetic renal disease (NDRD) in patients with type 2 diabetes mellitus to determine common clinical indicators suggestive of(More)
The TIS10 cDNA was cloned as a primary response gene transcript whose mRNA rapidly accumulates in 3T3 cells treated with serum, polypeptide growth factors, or phorbol esters. The sequence of the TIS10 cDNA suggested that the gene encodes a protein with strong similarities to prostaglandin G/H synthase/cyclooxygenase (EC 1.14.99.1). Transient transfection(More)
The TIS21 gene is a primary response gene that is induced rapidly and transiently in 3T3 cells by the tumor promoter and mitogen tetradecanoyl phorbol acetate. The predicted open reading frame of the TIS21 cDNA encodes a protein of 158 amino acids with no obvious similarity to any known protein. Antiserum prepared to TIS21 recombinant protein produced in(More)
Prostaglandin E2 (PGE2), PTH, and epidermal growth factor (EGF) are potent regulators of osteoblast proliferation. In UMR 106-01 rat osteosarcoma cells with osteoblast-like features, PGE2 and PTH inhibit, while EGF stimulates, mitogenesis. Both PGE2 and PTH increase intracellular cAMP levels, cytosolic calcium, and inositol phosphate turnover. In a variety(More)
Induction of early-response genes (tetradecanoyl phorbol acetate [TPA]-induced sequences, or TIS genes; R.W. Lim, B.C. Varnum, and H.R. Herschman, Oncogene 1:263-270, 1987) by granulocyte-macrophage colony-stimulating factor (GM-CSF) and TPA was examined both in a factor-dependent murine cell line, 32D clone 3, and in mature human neutrophils. When(More)
Vitamin D deficiency has been linked to cardiovascular disease and risk factors including hypertension. The authors sought to determine prevalence rates of hypertension in adults tested for 25-hydroxyvitamin D categorized by their levels and evaluate odds ratios for hypertension at lower 25-hydroxyvitamin D levels compared with optimal levels. A(More)
BACKGROUND Hyponatremia is a common electrolyte imbalance in hospitalized patients. It is associated with significant morbidity and mortality, especially if the underlying cause is incorrectly diagnosed and not treated appropriately. Often, the hospitalist is faced with a clinical dilemma when a patient presents with hyponatremia of an unclear etiology and(More)
