Project description:To further investigate gene expression in DEN-induced liver cancer in mice with Otud3 gene knockout, we employed RNA-seq profiling as a discovery platform to identify the pathways or biological processes potentially responsible for the occurrence of DEN-induced liver cancer in both wildtype and Otud3 knockout mice. Liver cancer tissues from Otud3 knockout mice and their littermates, with or without a 14-day-old DEN injection, were utilized as samples for analysis.

Project description:Ulcerative colitis (UC) develops through a complicated interaction between the host and microbiota. Intestinal fibroblasts are suggested to play crucial roles in the pathogenesis of UC. However, the influences of the host-microbiota interaction on the pathophysiology of intestinal fibroblasts remain poorly understood. Here, we reveal that OTUD3 suppresses pathologic activation of fibroblasts exposed to microbial cyclic GMP-AMP (3’3’-cGAMP) by deubiquitinating stimulator of interferon genes (STING) in the colon. Sting deficiency ameliorated dextran sodium sulfate-induced colitis in Otud3-/- mice. In addition, mice harboring an UC risk missense variant in the Otud3 gene showed pathological features of UC in the colon after transplantation of a fecal microbiome with the potential to produce excessive cGAMP from UC patients. Collectively, these results demonstrate the critical role of OTUD3 in the maintenance of intestinal homeostasis and highlight one mechanism of the interaction between the host (OTUD3 in fibroblasts) and microbiota (STING agonist) in UC development.

Project description:Ovarian tumour domain-containing protein 3 (OTUD3), a key OTU (ovarian tumour protease) family deubiquitylase, plays context-dependent roles in cancers. It suppresses tumorigenesis in breast, colon, liver and cervical cancer through stabilizing PTEN (phosphatase and tension homologue deleted on chromosome 10) while promotes lung tumorigenesis through stabilizing GRP78 (The glucose-regulated protein 78 kDa). The regulation especially post-translational modification of OTUD3 remains unclear. Here, we report that the carboxyl terminus of Hsc70-interacting protein (CHIP) is a ubiquitin ligase for OTUD3. CHIP interacts with, polyubiquitylates OTUD3 and promotes OTUD3 degradation. Knockdown of CHIP stabilizes OTUD3 which leads to elevated GRP78 levels in lung cancer cells. CHIP-knockdown lung cancer cells exhibit increased invasion in OTUD3 and GRP78 dependent manner. Further study demonstrates that CHIP-knockdown lung cancer cells are more prone to metastasize to mice lung when injected intravenously or subcutaneously. Moreover, the expression of CHIP is low in human lung cancer tissues and inversely correlates with OTUD3 expression and GRP78 expression. Furthermore, we identified CHIP mutations in human lung cancers, which reduce CHIP catalytic activity. These findings demonstrate that CHIP is a negative regulator of OTUD3 and CHIP suppresses lung cancer metastasis through inhibiting OTUD3-GRP78 signaling axis.
