New route for the activation of poly(ADP-ribose) polymerase-1: a passage that links poly(ADP-ribose) polymerase-1 to lipotoxicity?

Biochem J. 2015 Jul 15;469(2):e9-11. doi: 10.1042/BJ20150598.

Abstract

In this issue of Biochemical Journal, Chen and colleagues characterize an interaction between ACBD3 (acyl-CoA-binding domain-containing 3) protein and PARP [poly(ADP-ribose) polymerase]-1 through the activation of ERKs (extracellular-signal-regulated kinases). This study envisages a pathway through which ABCD3 translates enhanced fatty acid levels to ERK and consequently PARP-1 activation. The consequences of PARP-1 activation lead to cellular and tissue damage, implying that the ACBD3/PARP-1 pathway is an important pathway in lipotoxicity events.

Keywords: ACBD3; ERK; PARP; cholesterol; fatty acid; lipotoxicity.
