1 Hepatocyte-Specific Deletion of TIPARP, a Negative Regulator of the Aryl Hydrocarbon Receptor, Is Sufficient to Increase Sensitivity to Dioxin-Induced Wasting Syndrome. Dioxins TCDD-inducible poly(ADP-ribose) polymerase Mus musculus
2 We previously reported that loss of TCDD-inducible poly(adenosine diphosphate [ADP]-ribose) polymerase (TIPARP/PARP7/ARTD14), an AHR target gene and mono-ADP-ribosyltransferase, increases the sensitivity of mice to dioxin-induced toxicities. Dioxins TCDD-inducible poly(ADP-ribose) polymerase Mus musculus
3 We previously reported that loss of TCDD-inducible poly(adenosine diphosphate [ADP]-ribose) polymerase (TIPARP/PARP7/ARTD14), an AHR target gene and mono-ADP-ribosyltransferase, increases the sensitivity of mice to dioxin-induced toxicities. Dioxins TCDD-inducible poly(ADP-ribose) polymerase Mus musculus
4 We previously reported that loss of TCDD-inducible poly(adenosine diphosphate [ADP]-ribose) polymerase (TIPARP/PARP7/ARTD14), an AHR target gene and mono-ADP-ribosyltransferase, increases the sensitivity of mice to dioxin-induced toxicities. Dioxins TCDD-inducible poly(ADP-ribose) polymerase Mus musculus
5 Tiparpfl/flCreAlb and TiparpEx3-/- mice given a single injection of 10 mug/kg dioxin did not survive beyond days 7 and 9, respectively, while all Tiparp+/+ mice survived the 30-day treatment. Dioxins TCDD-inducible poly(ADP-ribose) polymerase Mus musculus
6 Taken together, these data illustrate that TIPARP is an important negative regulator of AHR activity, and that its specific loss in hepatocytes is sufficient to increase sensitivity to dioxin-induced steatohepatitis and lethality. Dioxins TCDD-inducible poly(ADP-ribose) polymerase Mus musculus
