Example sentences for: down-regulate
How can you use “down-regulate” in a sentence? Here are some example sentences to help you improve your vocabulary:
It was reported that PPAR activation could down-regulate the activity of AP-1 by interfering with the functions of c-jun [ 36 37 ] . Therefore, the following set of experiments was designed to test if PPAR activation could reduce c-jun activation in 25-OH-cholesterol treated microglia.
First, PTEN's protein phosphatase activity is able to down-regulate focal adhesion kinase (FAK) phosphorylation, which leads to the inactivation of the Ras/MAP kinase pathway [ 19 20 21 ] . Second, its lipid phosphatase activity targets the second messenger phosphatidylinositol 3,4,5-trisphosphate [PtdIns(3,4,5)P 3 ] and thereby blocks activation of the protein kinase B (PKB/Akt) pathway [ 11 18 22 23 24 ] . Whereas both of the above pathways are intimately involved in the control of cell growth and survival, PTEN-regulated FAK activity further appears to impinge on cell adhesion, cell migration, and cell invasion [ 20 21 ] . It therefore emerges that the loss of PTEN activity may confer increased survival ability, proliferative potential, and invasive capacity on cells, and thereby may promote progression towards a more malignant phenotype.
In brief, our results indicate that in MCF7/ADR cells NOM can significantly sensitize their chemosensitivity to ADR, down-regulate MDR1/P-gp and GSTπ expression levels in time-dependent manner, markedly increase intracellular ADR accumulation and enhance the cell cycle blocking activity of ADR.
Tat has been shown to down-regulate mannose receptor, EDF-1, CD3-gamma, and TCR/CD3 surface receptor [ 14 ] . Tat reduces mannose receptor levels and promoter activity in mature macrophages and dendritic cells by interfering with the host transcriptional machinery; resulting in decreased levels of surface mannose receptor needed for Ag (mannosylated albumin uptake) or pathogen capture (Pneumocystis carinii phagocytosis), and eventual delivery to MHC class II-containing intracellular compartments [ 15 ] . EDF-1, a gene down-regulated when endothelial cells are induced to differentiate in vitro , was shown to be down-regulated by Tat at the transcriptional level, resulting in the inhibition of endothelial cell growth and in the transition from a nonpolar cobblestone phenotype to a polar fibroblast-like phenotype [ 16 ] .
Consistent with this prediction, treatment with 0.3 μM norepinephrine for 24 h failed to down-regulate the receptor containing the motif mutated to EESSVAE, although the wild-type receptor with the EESSTSE motif was down-regulated by 35%.
