Lipopolysaccharide increases the amount of USP18. 14 / 16

reach
"We next sought to determine whether TNF-alpha and LPS could induce USP18 expression in hepatocytes via the induction of IFN-alpha."

reach
"TNF-alpha and LPS treatment also led to augmented USP18 protein expression by Western blotting (XREF_FIG) and by intracellular staining (XREF_FIG to XREF_FIG)."

reach
"We observed that neither IFN-α, LPS, nor TNF-α induce much, if any, hepatocyte expression of IFN-α or IFN-γ, although the same doses induce strong expression of USP18 (Fig. 5)."

reach
"USP18 mRNA expression was induced by TNF-α and LPS but not by IL-6 or IL-10 (Fig. 1A)."

reach
"MacParland et al. showed that TNF-alpha or LPS could target USP18 expression and thus inhibit IFN signaling [XREF_BIBR]."

"TABLE 1: Inhibition of inflammatory signaling impairs TNF-α- and LPS-induced USP18 expressionaFIG 1: USP18 expression is upregulated by TNF-α and LPS."

reach
"USP18 mRNA expression was induced by TNF-alpha and LPS but not by IL-6 or IL-10 (XREF_FIG)."

"LPS strongly activates UBP43 expression in macrophages, which is paralleled by changes in UBP43 protein levels."

reach
"TNF-α and LPS treatment also led to augmented USP18 protein expression by Western blotting (Fig. 1C) and by intracellular staining (Fig. 1D to F)."

reach
"Having shown that LPS and TNF-alpha stimulation increases hepatocyte USP18 expression, we then sought to determine whether we could pharmacologically inhibit the induction of USP18 by LPS and TNF-alpha."
