Example sentences for: regulator
How can you use “regulator” in a sentence? Here are some example sentences to help you improve your vocabulary:
The involvement of Rho GTPases in regulating integrin dependent events such as leukocyte homotypic aggregation and in chemokine upregulation of integrin-mediated adhesion has recently been identified [ 18 19 ] . ADP-ribosylation of Rho in neutrophils by treatment with C3 not only inhibits cellular locomotion, but augments chemoattractant induced actin polymerization [ 20 21 ] . Moreover, inactivation of Rho in monocytic cells leads to accelerated formation of filopodia, and it has been proposed that Rho is a negative regulator of actin polymerization within this cell type [ 22 ] . Active Rho is also required for normal morphology, motility, and cytolytic activity of IL-2 activated NK cells [ 23 24 ] . We and others have demonstrated the importance of Rho in T lymphocyte activation [ 25 26 ] . Given the role played by Rho in the regulation of actin microfilaments in other cell types, and the indispensability of a functional actin cytoskeleton in lymphocyte motility and activation, it is of importance to study Rho's role in the regulation of T lymphocyte integrin function and maintenance of cytoskeletal organization.
8 A regulator might well be required to administer any price caps, incremental-cost floors, or other restrictions.
Ese-1/Esx is a member of the Ets transcription factor family and is expressed mainly in epithelial tissue [ 30 ] . Its expression has been detected during mammary gland development and breast tumorigenesis [ 47 48 ] . It is noteworthy that Ese-1/Esx is a potential transcriptional regulator of the TGFβ type II receptor [ 31 ] and overexpression of Ese-1/Esx in non-invasive cells leads to a reduction in cell growth in the presence of TGFβ, presumably because of an increased TGFβ type II receptor level [ 49 ] . It is interesting that TGFβ-dependent downregulation of Ese-1/Esx is not affected by SB-203580.
Smad1, as one of the three known R-Smads of BMPs, has been extensively studied within the scope of its phosphorylation, interaction with Smad4, nuclear translocation, DNA binding and protein-protein interactions related to its function as a transcriptional regulator.
3 region to which RASSF1A maps undergoes deletions in many solid tumor types, including GCTs [ 9 ] . RASSF1A encodes a splice variant of human RAS effector homologue, which interacts with the XPA protein and functions as a negative regulator of cell growth [ 16 17 ] . RASSF1A has been shown to be inactivated by promoter methylation in a variety of tumor types [ 16 17 18 19 ] . The 17q21 and 17p13 regions, to which BRCA1 and HIC1 map, respectively, also have been characterized by high frequency of LOH in GCT [ 9 ] . The BRCA 1 gene plays critical roles in DNA repair and recombination, cell cycle checkpoint control, and transcription and has been shown to be hypermethylated in breast-ovarian cancer [ 4 ] . The HIC1 gene is also often hypermethylated in many human cancers [ 20 21 22 ] . The DNA repair gene MGMT encodes O(6)-methylguanine-DNA methyltransferase and this enzyme effectively removes DNA adducts formed by alkylating agents [ 23 ] . Epigenetic inactivation of the MGMT gene was reported in a wide variety of cancers [ 24 25 ] . Also, a low frequency of methylation of the APC , RARB , and FHIT genes was detected in NSGCTs.
