Tankyrase inhibition preserves osteoarthritic cartilage by coordinating cartilage matrix anabolism via effects on SOX9 PARylation
It is characterized by the fact that its double bonds are separated by only one single bond, which is rare in nature
In viral hepatitis, activation of T cells plays an important role in eliminating viruses and promotes hepatocellular damage.5, 6 Injection of concanavalin A (ConA), a T-cell mitogen, has been widely used to study how T-cell activation induces liver injury in mice.7-9 In this model, administration of ConA rapidly activates T cells and natural killer T (NKT) cells and subsequently activates Kupffer cells/macrophages, followed by producing a variety of proinflammatory cytokines (eg, tumor necrosis factor (TNF)-, interferon (IFN)-) that cause hepatocyte injury via the activation of their downstream signals (eg, nuclear factor (NF)-B, signal transducer and activator of transcription 1 (STAT1)).10, 11 Activated immune cells also produce several hepatoprotective cytokines (eg, interleukin (IL)-6, IL-22) that promote liver repair via the activation of STAT3.10-12 We have previously demonstrated that chronic ethanol feeding exacerbated ConA-induced T-cell-mediated hepatitis via the upregulation of the TNF--NF-B signalling pathway and subsequent upregulation of chemokines/adhesive molecules and recruitment of leucocytes into the liver.13 In contrast, chronic ethanol feeding attenuates the activation of the hepatocyte survival signal STAT3 in T-cell hepatitis.13 Thus, alcohol consumption dysregulates the activation of cytokines and their downstream signals, thereby exacerbating T-cell hepatitis, which likely contributes to the synergistic effect of alcohol and viral hepatitis on liver disease progression
