The Expression of the Ubiquitin Ligase SIAH2 (Seven In Absentia Homolog 2) Is Increased in Human Lung Cancer
OBJECTIVES Lung cancer is the leading cause of cancer-related deaths worldwide. Overall 5-year survival has shown little improvement over the last decades. Seven in absentia homolog (SIAH) proteins are E3 ubiquitin ligases that mediate proteasomal protein degradation by poly-ubiquitination. Even though SIAH proteins play a key role in several biological processes, their role in human cancer rem...
متن کاملNrf2b, novel zebrafish paralog of oxidant-responsive transcription factor NF-E2-related factor 2 (NRF2).
NF-E2-related factor 2 (NRF2; also called NFE2L2) and related NRF family members regulate antioxidant defenses by activating gene expression via antioxidant response elements (AREs), but their roles in embryonic development are not well understood. We report here that zebrafish (Danio rerio), an important developmental model species, possesses six nrf genes, including duplicated nrf1 and nrf2 g...
متن کاملCR6-interacting Factor 1 (CRIF1) Regulates NF-E2-related Factor 2 (NRF2) Protein Stability by Proteasome-mediated Degradation
Free radicals generated by oxidative stress cause damage that can contribute to numerous chronic diseases. Mammalian cells respond to this damage by increased transcription of cytoprotective phase II genes, which are regulated by NRF2. Previously, it has been shown that NRF2 protein levels increase after oxidative stress because its negative regulator, KEAP1, loses its ability to bind NRF2 and ...
متن کاملNuclear factor E2-related factor-2 (Nrf2) is required for NLRP3 and AIM2 inflammasome activation.
Despite the number of extensive studies on the immune function and signaling of inflammasomes in various diseases, the activating mechanism of inflammasome, especially the NLRP3 inflammasome, is not fully understood. Nuclear factor E2-related Factor-2 (Nrf2), a key transcription factor that regulates cellular redox homeostasis, has been reported to play both protective and pathogenic roles depe...
متن کاملEffect of disrupting seven-in-absentia homolog 2 function on lung cancer cell growth.
BACKGROUND Hyperactivated epidermal growth factor receptor (EGFR) and/or RAS signaling drives cellular transformation and tumorigenesis in human lung cancers, but agents that block activated EGFR and RAS signaling have not yet been demonstrated to substantially extend patients' lives. The human homolog of Drosophila seven-in-absentia--SIAH-1 and SIAH-2--are ubiquitin E3 ligases and conserved do...
