The MNK kinases are downstream of both the p38 and ERK MAP kinase pathways and act to increase gene expression. MNK inhibition using the compound CGP57380 has recently been reported to inhibit tumor necrosis factor (TNF) production in macrophage cell lines stimulated with Escherichia coli lipopolysaccharide (LPS). However, the range of receptors that signal(More)
Tristetraprolin (TTP) is the prototype for a family of RNA binding proteins that bind the tumor necrosis factor (TNF) messenger RNA AU-rich element (ARE), causing deadenylation of the TNF poly(A) tail, RNA decay, and silencing of TNF protein production. Using mass spectrometry sequencing we identified poly(A) binding proteins-1 and -4 (PABP1 and PABP4) in(More)
