The Tumor Suppressor CYLD Interacts with TRIP and Regulates Negatively Nuclear Factor κB Activation by Tumor Necrosis Factor
Cylindromas are benign adnexal skin tumors caused by germline mutations in the CYLD gene. In most cases the second wild-type allele is lost in tumor tissue, suggesting that CYLD functions as tumor suppressor. CYLD is a protein of 956 amino acids harboring a functional deubiquitinating domain at the COOH-terminal end. To shed more light on the function of CYLD, we have performed a yeast two hybr...
متن کاملThe dual-specificity phosphatase DUSP14 negatively regulates tumor necrosis factor- and interleukin-1-induced nuclear factor-κB activation by dephosphorylating the protein kinase TAK1.
The transcription factor NF-κB is critically involved in the inflammatory response triggered by the proinflammatory cytokines TNF and IL-1. Various studies have demonstrated that activation of TAK1 (TGF-β-activated kinase 1) is an essential step in TNF- and IL-1-induced NF-κB activation pathways. In this study, we identified a member of the dual-specificity phosphatase family, DUSP14, as a nega...
متن کاملPrion protein is required for tumor necrosis factor α (TNFα)-triggered nuclear factor κB (NF-κB) signaling and cytokine production
The expression of normal cellular prion protein (PrP) is required for the pathogenesis of prion diseases. However, the physiological functions of PrP remain ambiguous. Here, we identified PrP as being critical for tumor necrosis factor (TNF) α-triggered signaling in a human melanoma cell line, M2, and a pancreatic ductal cell adenocarcinoma cell line, BxPC-3. In M2 cells, TNFα up-regulates the ...
متن کاملUSP18 negatively regulates NF-κB signaling by targeting TAK1 and NEMO for deubiquitination through distinct mechanisms
Nuclear factor κB (NF-κB) is a key transcription factor in inflammatory immune responses and cell survival. Multiple types of ubiquitination play critical roles in the activation of NF-κB signaling, yet the molecular mechanisms responsible for their reversible deubiquitination are still poorly understood. In this study, we identified a member of the deubiquitinases family, ubiquitin-specific pr...
متن کاملTumor Necrosis Factor-α and Interleukin-1- β Polymorphisms in Pre-Eclampsia
Background: Pre-eclampsia is the most common critical condition during pregnancy. Plasma concentrations of tumor necrosis factor-alpha (TNF-α) and interleukin-1-beta (IL-1β) increase in pregnant women with pre-eclampsia, compared to normal pregnant women. Objective: To investigate the polymorphisms of IL-1β (C+3954T), TNF-α (G- 308A), and (G-238A) in preeclemptic women northeastern Iran. Me...
