Research highlights

We have been working on inflammation-related signaling pathways, gene regulation, and cancer development for many years. Besides exploring the molecular action mechanisms of several anti-inflammatory drugs, we demonstrated ligand-dependent and -independent action mechanisms of NOD2 in regulating TLR4 signaling and responses in macrophages. Regarding statins, which are HMG-CoA reductase inhibitors and widely used as lipid-lowering agents, we identified several novel anti-inflammatory and cell protective actions of statins, and provided valuable information to support their potential therapeutic uses in inflammatory diseases. Decoy receptor 3 (DcR3), a soluble receptor belonging to TNFR, is a biomarker of cancer progression. In our lab, we found DcR3 can exert inflammatory actions to modulate cancer progression via decoy and non-decoy action manners. Cell death is an important issue to control cellular homeostasis and biological functions. Among several types of programmed cell death, we have demonstrated the signaling cascades involved in necroptosis, parthanatos and autophagic death. In this respect, novel functions of caspase-8 in keratinocyte differentiation and autophagy induction were reported.
