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:

  • Interestingly, the promoter activity of the CD87 gene was shown to decline after infection [ 32 ] , implying that post integration of HIV-1 may in fact down-regulate CD87 gene expression.

  • 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.

  • First, antisense oligonucleotides were used to down-regulate endogenous PLD2 activity.

  • IL-4 can down-regulate the production of proinflammatory and Th1-type cytokines by inducing mRNA degradation and upregulating the expression of inhibitors of proinflammatory cytokines such as IL-1Ra [ 3, 4].

  • To test this hypothesis, we mutated the opossum alpha-2C serines and threonine residues to alanines and valine, respectively, and tested whether the expressed receptors would down-regulate.
