show ga
p38 mitogen-activated protein kinase (MAPK) stabilises pro-inflammatory mediator
mRNAs by inhibiting AU-rich element (ARE)-mediated decay. We show that in
bone-marrow derived murine macrophages tristetraprolin (TTP) is necessary for the
p38 MAPK-sensitive decay of several pro-inflammatory mRNAs, including
cyclooxygenase-2 and the novel targets interleukin (IL)-6, and IL-1alpha.
TTP(-/-) macrophages also strongly overexpress IL-10, an anti-inflammatory
cytokine that constrains the production of the IL-6 despite its disregulation at
the post-transcriptional level. TTP directly controls IL-10 mRNA stability, which
is increased and insensitive to inhibition of p38 MAPK in TTP(-/-) macrophages.
Furthermore, TTP enhances deadenylation of an IL-10 3'-untranslated region RNA in
vitro.
