B1 Isoforms to Bind the Angiotensinogen Gene Acute-Phase Response Element: A Stimulus-Specific Pathway for NF-
B Activation
Department of Internal Medicine (M.J., T.M., J.S., Y.H., A.R.B.) Department of Microbiology & Immunology (I.B.) Sealy Center for Molecular Sciences (A.R.B.) University of Texas Medical Branch Galveston, Texas 77555-1060
The vasopressor angiotensin II (AII) activates
transcriptional expression of its precursor, angiotensinogen.
This biological "positive feedback loop" occurs through an
angiotensin receptor-coupled pathway that activates a
multihormone-responsive enhancer of the angiotensinogen promoter,
termed the acute-phase response element (APRE). Previously, we showed
that the APRE is a cytokine [tumor necrosis factor-
(TNF
)]-
inducible enhancer by binding the heterodimeric nuclear factor-
B
(NF-
B) complex Rel ANF-
B1. Here, we compare the mechanism for
NF-
B activation by the AII agonist, Sar1
AII, with TNF
in HepG2 hepatocytes. Although
Sar1 AII and TNF
both rapidly activate
APRE-driven transcription within 3 h of treatment, the pattern of
inducible NF-
B binding activity in electrophoretic mobility shift
assay is distinct. In contrast to the TNF
mechanism, which strongly
induces Rel ANF-
B1 binding, Sar1
AII selectively activates a heterogenous pattern of NF-
B1 binding.
Using a two-step microaffinity DNA binding assay, we observe that
Sar1 AII recruits 50-, 56-, and 96-kDa NF-
B1
isoforms to bind the APRE. Binding of all three NF-
B1 isoforms
occurs independently of changes in their nuclear abundance or
proteolysis of cytoplasmic I
B inhibitors. Phorbol ester-sensitive
protein kinase C (PKC) isoforms are required because PKC
down-regulation completely blocks AII-inducible transcription and
inducible NF-
B1 binding. We conclude that AII stimulates the NF-
B
transcription factor pathway by activating latent DNA-binding activity
of NF-
B subunits through a phorbol ester-sensitive (PKC-dependent)
mechanism.
