NOD1 induces pyroptotic cell death to aggravate liver ischemia-reperfusion injury in mice.

Nucleotide-binding oligomerization domain 1 (NOD1) can direct the release of inflammatory factors and influence autophagy and apoptosis in hepatic ischemia-reperfusion injury (IRI) in mice. As pyroptosis is involved in a number of inflammatory reactions, in this report, we investigated the potential for NOD1 to affect pyroptosis. We found that an increased expression of NOD1 during IRI was related to activation of the pyroptotic signaling pathway.

Effects of heme oxygenase-1-modified bone marrow mesenchymal stem cells on microcirculation and energy metabolism following liver transplantation.

Aim: To investigate the effects of heme oxygenase-1 (HO-1)-modified bone marrow mesenchymal stem cells (BMMSCs) on the microcirculation and energy metabolism of hepatic sinusoids following reduced-size liver transplantation (RLT) in a rat model.

Methods: BMMSCs were isolated and cultured using an adherent method, and then transduced with HO-1-bearing recombinant adenovirus to construct HO-1/BMMSCs. A rat acute rejection model following 50% RLT was established using a two-cuff technique.
