Pyridinoline (PYD), deoxypyridinoline (DPD), and N-telopeptide (NTX) are markers of bone resorption. In cancer patients with bone metastases, NTX is more often elevated than either of the pyridinolines. Bisphosphonates inhibit osteoclasts and their t

The role of nuclear factor (NF)-kappaB transcription factor in silica-induced cyclooxygenase (COX) II gene expression was examined in the rat alveolar macrophage cell line NR8383. Our results indicate that NF-kappaB can be activated in this cell line

Tetrandrine is a bisbenzylisoquinoline alkaloid isolated from a natural Chinese herbal medicine. While this alkaloid has been shown to exhibit antifibrotic and anti-inflammatory activities, its mechanism of action is unknown. The present study was de

The disposition of iron in the alveolar macrophage (AM) may be a critical factor in its reactivity to inhaled mineral dust. Dust particles such as coal and silica contain leachable iron or iron oxides on their surface which may become available as a

It has been suggested that prior exposure to mineral dust may attenuate the ability of the alveolar macrophage (AM) to respond to subsequent provocative stimuli, thus compromising the host defense mechanism. On the contrary, prior exposure of the AM

In this report, we demonstrate that NF-kappa B, a ubiquitous transcription factor, plays an essential role in silica-induced inflammatory mediator production in the mouse macrophage cell line RAW 264.7. Compared to the effect of lipopolysaccharide (L

Eicosanoids and cytokines produced by alveolar macrophages (AM) are key mediators of pulmonary inflammation and fibrosis. In order to determine if eicosanoid production and cytokine production are altered in AM obtained from coal miners, we compared

Tumor necrosis factor alpha (TNF alpha) and thromboxane A2 (TXA2) are major products of the activated alveolar macrophage and serve as key mediators of lung injury. In order to determine if the synthesis of TXA2 and the release of TNF alpha are assoc

Nitric oxide (NO), a nitrogen-free radical, plays an important role in mediating inflammatory reaction and cytotoxicity of tissue. To determine whether NO was involved in silica-induced pulmonary tissue damage, we studied the effects of silica on nit

In this report the differential regulation of NF-kappa B and nitric oxide (NO) was investigated in the mouse macrophage cell line RAW 264.7 following exposure to a mineral dust (silica) and/or an endotoxin (Lipopolysaccharide, LPS). The results indic
