Histone acetyltransferase
HBO1 inhibits
NF-kappaB activity by coactivator sequestration ... Since the androgen receptor and NF-kappaB transcription factors crossmodulate their transcriptional activity, we investigated whether
HBO1 regulates
NF-kappaB signaling ... Here, we report that in 293T cells
HBO1 reduced dose-dependently
NF-kappaB activity stimulated by TNFalpha, or by overexpressing p65/RelA, RelB, or cRel ... Electrophoretic mobility-shift assays demonstrated that HBO1 was neither perturbing the formation of p65/RelA DNA complexes nor binding itself to the kappaB consensus sequence or to p65/RelA, suggesting that
HBO1 reduced
NF-kappaB activity by squelching a cofactor
Nozell et al., Mol Cell Biol 2008
(Glioma) :
We demonstrate that an
ING4 and NF-kappaB interaction exists but does not
prevent NF-kappaB activation, nuclear translocation, or DNA binding
Coles et al., Proc Natl Acad Sci U S A 2010
(Inflammation) :
We have generated Ing4-deficient mice to explore the
role of
Ing4 in development, tumorigenesis, and in
NF-kappaB signaling ... However, increased promoter occupancy by RelA in LPS stimulated, Ing4-null cells does not always correlate with increased NF-kappaB target-gene expression, as
RelA activation of a subset of cytokine promoters also
requires Ing4 for proper histone H4 acetylation ... Furthermore, activation of the IkappaB alpha promoter by
RelA is also
Ing4 dependent , and LPS stimulated, Ing4-null cells have reduced levels of IkappaB alpha promoter H4 acetylation and IkappaB gene expression ... Thus,
Ing4 negatively
regulates the cytokine mediated inflammatory response in mice by facilitating
NF-kappaB activation of IkappaB promoters, thereby suppressing nuclear RelA levels and the activation of select NF-kappaB target cytokines
Byron et al., PloS one 2012
(Breast Neoplasms...) :
Conversely, ectopic expression of
ING4 inhibited
p65/RelA phosphorylation in T47D and MCF7 breast cancer cells
