Hyperproduction of IL-6 caused by aberrant TDP-43 overexpression in high-fat diet-induced obese mice

Inclusion of Tat-activating regulatory DNA-binding protein-43 (TDP-43) due to hyperphosphorylation or hyperubiquitination is a cause of neurodegenerative disease. Cellular TDP-43 expression is tightly controlled through a negative feedback loop involving its mRNA. Recently, we reported that the TDP-43-mediated sub-nuclear body is an essential site of interleukin-6 (IL-6) pre-mRNA processing. Here we show that mice fed on a high-fat diet exhibit...
