TL;DR: It is hypothesized that the single chain enzyme has restricted activity on most proteins but high activity on the proapoptotic protein Bid, potentially supporting a prodeath role for both cleaved and uncleaved caspase-10.
Abstract: Two apical caspases, caspase-8 and -10, are involved in the extrinsic death receptor pathway in humans, but it is mainly caspase-8 in its apoptotic and nonapoptotic functions that has been an intense research focus. In this study we concentrate on caspase-10, its mechanism of activation, and the role of the intersubunit cleavage. Our data obtained through in vitro dimerization assays strongly suggest that caspase-10 follows the proximity-induced dimerization model for apical caspases. Furthermore, we compare the specificity and activity of the wild-type protease with a mutant incapable of autoprocessing by using positional scanning substrate analysis and cleavage of natural protein substrates. These experiments reveal a striking difference between the wild type and the mutant, leading us to hypothesize that the single chain enzyme has restricted activity on most proteins but high activity on the proapoptotic protein Bid, potentially supporting a prodeath role for both cleaved and uncleaved caspase-10.

TL;DR: Chronic-plus-binge ethanol feeding activates hepatic iNKT cells, which play a critical role in the development of early alcoholic liver injury, in part by releasing mediators that recruit neutrophils to the liver, and thus, iN KT cells represent a potential therapeutic target for the treatment of alcoholic liver disease.
Abstract: Neutrophil infiltration is a hallmark of alcoholic steatohepatitis; however, the underlying mechanisms remain unclear. We previously reported that chronic-plus-binge ethanol feeding synergistically induces hepatic recruitment of neutrophils, which contributes to liver injury. In this paper, we investigated the roles of invariant natural killer T (iNKT) cells in chronic-plus-binge ethanol feeding-induced hepatic neutrophil infiltration and liver injury. Wild-type and two strains of iNKT cell-deficient mice (CD1d- and Jα18-deficient mice) were subjected to chronic-plus-binge ethanol feeding. Liver injury and inflammation were examined. Chronic-plus-binge ethanol feeding synergistically increased the number of hepatic iNKT cells and induced their activation, compared with chronic feeding or binge alone. iNKT cell-deficient mice were protected from chronic-plus-binge ethanol-induced hepatic neutrophil infiltration and liver injury. Moreover, chronic-plus-binge ethanol feeding markedly upregulated the hepatic expression of several genes associated with inflammation and neutrophil recruitment in wild-type mice, but induction of these genes was abrogated in iNKT cell-deficient mice. Importantly, several cytokines and chemokines (e.g., MIP-2, MIP-1, IL-4, IL-6 and osteopontin) involved in neutrophil infiltration were upregulated in hepatic NKT cells isolated from chronic-plus-binge ethanol-fed mice compared to pair-fed mice. Finally, treatment with CD1d blocking antibody, which blocks iNKT cell activation, partially prevented chronic-plus-binge ethanol-induced liver injury and inflammation. Chronic-plus-binge ethanol feeding activates hepatic iNKT cells, which play a critical role in the development of early alcoholic liver injury, in part by releasing mediators that recruit neutrophils to the liver, and thus, iNKT cells represent a potential therapeutic target for the treatment of alcoholic liver disease.

TL;DR: It is demonstrated that concomitant inhibition of MDM2 by nutlin-3a and of XIAP by small molecule antagonists synergistically induced apoptosis in p53 wild-type OCI-AML3 and Molm13 cells, and that the combination strategy holds promise for expedited translation into the clinic.

TL;DR: The present findings are consistent with a predicted antidepressant-like effect of GalR2 signaling, suggesting that GalR 2 might be a valid drug target for depressive disorders.
