Lipopolysaccharide is a potent monocyte/macrophage-specific stimulator of human immunodeficiency virus type 1 expression
Lipopolysaccharide (LPS) potently stimulates human immunodeficiency virus type 1-long terminal repeat (HIV-1-LTR) CAT constructs transfected into monocyte/macrophage-like cell lines but not a T cell line. This effect appears to be mediated through the induction of nuclear factor kappa B (NF-kappa B). Electrophoretic mobility shift assays demonstrate that LPS induces a DNA binding activity indis...
متن کاملTEFM is a potent stimulator of mitochondrial transcription elongation in vitro
A single-subunit RNA polymerase, POLRMT, transcribes the mitochondrial genome in human cells. Recently, a factor termed as the mitochondrial transcription elongation factor, TEFM, was shown to stimulate transcription elongation in vivo, but its effect in vitro was relatively modest. In the current work, we have isolated active TEFM in recombinant form and used a reconstituted in vitro transcrip...
متن کاملLeukotriene B4 is a potent and stereospecific stimulator of neutrophil chemotaxis and adherence.
We studied the effects of leukotrienes on in vitro functions of neutrophil polymorphonuclear (PMN) granulocytes. Leukotriene B4 (LTB4) evoked a stimulated and directed migration of neutrophils under agarose with an optimum concentration of 10(-6)M, whereas two nonenzymatically formed isomers (compounds I and II) induced this response at 10(-5)M. Leukotriene C4 (LTC4) and 5-hydroxyeicosate-traen...
متن کاملKisspeptin-10 is a potent stimulator of LH and increases pulse frequency in men.
CONTEXT Kisspeptins stimulate GnRH and thus gonadotropin secretion. Kisspeptin-10 is the minimal kisspeptin sequence with full intrinsic bioactivity, but it has not been studied in man. OBJECTIVE We investigated our hypothesis that kisspeptin-10 increases GnRH and thus LH pulse frequency. DESIGN AND PARTICIPANTS The dose response of kisspeptin-10 was investigated by administering iv bolus d...
