Revealing A-Raf functions through its interactome

Publication date: August 2018Source: Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, Volume 1866, Issue 8Author(s): Xin-Yu Zhang, Hui Guo, Bing Han, Xu-Min Zhang, Ying Huang, Yang Yang, Ying Liu, Xiao-Xi Guo, Qian Hao, Su An, Tian-Rui XuAbstractA-Raf is a member of the Raf kinase family. Unlike B-Raf and C-Raf, the functions of A-Raf remain obscure. To gain more insight into the biological functions of A-Raf, we investigated the A-Raf interactome using proteomics. We found 132 proteins that interact with A-Raf and confirmed the interaction of 12 of these proteins with A-Raf by western blotting. Our data suggested that A-Raf regulates apoptosis, RNA catabolism, GTPase activity, and cell adhesion by interacting with proteins located in different cellular compartments. We identified all ten hallmarks of cancer in these interacting proteins, suggesting that A-Raf is involved in carcinogenesis. Our results also indicated that A-Raf may play a role in different diseases and signaling pathways. These findings have identified potential regulators of A-Raf and provide a systemic insight into its biological functions.

CONCLUSIONS: Oncotype is a cost-effective intervention from a health system perspective since each QALY gained costs less than 25,000 euros. From a societal perspective, it is dominant since it provides greater health and is accompanied by cost savings. PMID: 30442434 [PubMed - as supplied by publisher]

Abstract Human liver fluke infection caused by Opisthorchis viverrini is a major public health problem in Mekong countries such as Thailand, Laos, Cambodia, Vietnam, and Myanmar with over 10 million infected through consumption of fish containing infective metacercariae. With no tissue migration phase and living entirely within the larger secondary (intrahepatic) bile ducts, liver flukes are only exposed to a biliary mucosal immune response, while their excretory and secretory products also stimulate chronic inflammation of biliary epithelium. Neither mucosal nor tissue immune responses appear to cause parasi...

Abstract The availability of genome and transcriptome data of the liver fluke Opisthorchis viverrini provides the foundation for exploration of gene function and its effect on host-parasite interactions and pathogenesis of O. viverrini-associated bile duct cancer. Functional genomics approaches address the function of DNA at levels of the gene, RNA transcript and protein product using informative manipulations of the genome, epigenome, transcriptome, proteome, microbiome and metabolome. Advances in functional genomics for O. viverrini have thus far focused on RNA interference. The flukes have been transfected with...

Abstract The liver flukes Opisthorchis viverrini, O. felineus, and Clonorchis sinensis are closely related fish-borne trematodes endemic in East Asia, Eurasia, and Siberia. Following ingestion, the parasites locate to the biliary tree, where chronic infection frequently leads to cholangiocarcinoma (CCA). Infection with C. sinensis or O. viverrini is classified as a Group 1 carcinogen by the International Agency for Research on Cancer. Infection with O. felineus may also be carcinogenic. The mechanism(s) by which infection with these liver flukes culminates in CCA remain elusive, although they are likely to be mult...
