Example sentences for: tgfβ-dependent
How can you use “tgfβ-dependent” in a sentence? Here are some example sentences to help you improve your vocabulary:
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.
The altered kinetic of TGFβ-dependent Smad3 nuclear entry as induced by SB-203580 coincided with the efficacy by which this agent repressed the activity of the different TGFβ target genes.
The smad7 gene contains a perfect palindromic Smad binding element (GTCTAGAC) while the pai-1 and the pthrp promoters harbor AGAC tandem repeats [ 19 33 ] which binds Smad proteins less efficiently [ 34 ] . The upa gene contains only an AP1-binding site which resembles the Smad3/4-responsive AGAC motif [ 35 ] . A weaker binding site could require Smad3 to be present at higher concentrations for efficient binding and would make TGFβ-dependent transcription from a gene more vulnerable to reduced nuclear accumulation of the Smad3 protein.
Strikingly, SB-202190 and SB-203580 suppressed TGFβ-dependent activation of those genes that are important for the acquisition of invasive behavior, while having no effect on the expression of the natural TGFβ inhibitor Smad7.
The strongest effect of SB-203580 was found on the TGFβ-dependent expression of pthrp and upa . In these cases, the inhibitor completely eliminated responsiveness to TGFβ.
