Tumor necrosis factor alpha (TNF-α) is a critical mediator of inflammation, and its production is tightly regulated, with control points operating at nearly every step of its biosynthesis. We sought to identify uncharacterized TNF-α 3' untranslated region (3'UTR)-interacting proteins utilizing a novel screen, termed the RNA capture assay. We identified CARHSP1, a cold-shock domain-containing protein. Knockdown of CARHSP1 inhibits TNF-α protein production in lipopolysaccharide (LPS)-stimulated cells and reduces the level of TNF-α mRNA in both resting and LPS-stimulated cells. mRNA stability assays demonstrate that CARHSP1 knockdown decreases TNF-α mRNA stability from a half-life (t(1/2)) of 49 min to a t(1/2) …

Curcumin, a pleiotropic polyphenol derived from turmeric plants Curcuma Longa with rhizome, exhibits strong evidence as an anti-inflammation, anti-oxidant and anti-cancer reagent both in vitro and in vivo. Due to its low stability and systemic bioavailability, a large amount of curcumin has to be administrated to achieve therapeutic effects both in animal and in human. The major effort to overcome this barrier is making by encapsulation of curcumin into nanoparticles such as polymers and liposomes; some promising data have demonstrated the effectiveness of such method. Exosomes are vesicle-like nanoparticles secreted by living cells. Exosomes contain both cell surface molecules and …
