Abstract
Research over the past decade has suggested important roles for pseudogenes in physiology and disease. In vitro experiments
demonstrated that pseudogenes contribute….

A mammalian pseudogene lncRNA at the interface of inflammation and anti-inflammatory therapeutics | eLife

June 22, 2014

QT:{{”
We identify an lncRNA pseudogene, Lethe (named after the mythological river of forgetfulness, for its role in negative feedback), which is expressed in response to proinflammatory cytokines TNFα and IL-1β, and the anti-inflammatory agent, dexamthasone, but is not responsive to microbial components, and is primarily found on the chromatin. Lethe is regulated by RelA, independent of pseudogene family members and proximal genes. Additionally, Lethe is dramatically downregulated in aged spleen. Finally, Lethe binds directly to RelA to inhibit NF-κB DNA binding activity. These findings suggest that Lethe may function as a novel negative regulator of NF-κB, to help fine tune the inflammatory response.
