Recombinant Human Sulfhydryl oxidase 1 (QSOX1), partial

1. This study provides a key example of the effect of glycosylation on Golgi exit and contributes to an understanding of late secretory sorting and quality control. PMID: 29757379
2. High QSOX1 expression correlates with tumor invasiveness PMID: 29804717
3. High QSOX1 expression is a strong and independent factor of reduced survival in breast cancer and may represent a biomarker for aggressive disease and a potential treatment target PMID: 27562495
4. Data indicate ebselen as an in vitro inhibitor of quiescin sulfhydryl oxidase 1 (QSOX1) enzymatic activity. PMID: 26158899
5. QSOX1 immunoexpression was observed in the non-neoplastic cerebellum samples and the medulloblastoma samples PMID: 25908093
6. High levels of QSOX1 RNA expression is associated with breast cancer. PMID: 23536962
7. these studies suggest that QSOX1 is a predictive biomarker for luminal cancers and that it may be a useful target for elusive luminal B disease PMID: 23680167
8. QSOX1 may be revealed as an important player in cancer detection and prognosis. Defining the mechanism(s) of QSOX1 activity in tumors and in in vivo models will provide important insights into how to target QSOX1 with anti-neoplastic agents. PMID: 24359107
9. Examination of the unusual kinetics of QSOX1 toward cysteine and glutathione at low micromolar concentrations suggests that circulating QSOX1 is unlikely to significantly contribute to the oxidation of these monothiols in plasma PMID: 24468475
10. QSOX1 may be involved in neuroblastoma differentiation and regression and may thus function as a biomarker for identifying risk groups for this neoplasm. PMID: 24704990
11. QSOX1 is induced by hypoxic stimuli and identified that QSOX1 is a direct target of HIF-1. PMID: 24008827
12. Data suggest that isoenzyme QSOX1A is secreted from mammalian cells despite transmembrane domain; QSOX1A is cleaved at internal sites and processed within Golgi apparatus to yield soluble enzyme that forms dimer upon cleavage of C-terminal domain. PMID: 23713614
13. QSOX1 is a potential new prognostic marker which may prove of use in the staging of breast tumours and the stratification of breast cancer patients. PMID: 23460839
14. QSOX1 activity was required for incorporation of laminin into the extracellular matrix (ECM) synthesized by fibroblasts, and ECM produced without QSOX1 was defective in supporting cell-matrix adhesion. PMID: 23704371
15. crystal structure PMID: 22801504
16. These results propose for the first time possible roles for QSOX1 in atherosclerosis. PMID: 22069028
17. Taken together, our results suggest that the mechanism of QSOX1-mediated tumor cell invasion is by activation of MMP-2 and MMP-9. PMID: 21989104
18. Data suggested that the C449-C452 motif was essential for the activity of human QSOX 1b; the C70-C73 motif was fundamental in electron transfer from thiol-containing substrate including reduced proteins, DTT, GSH. PMID: 21148546
19. A partial QSOX1 crystal structure reveals a single-chain pseudo-dimer mimicking the quaternary structure of Erv enzymes. PMID: 20211621
20. In the plasma peptidome of patients with ductal adenocarcinoma of the pancreas (DAP), a prominent peptide was identified from the QSOX1 parent protein. This peptide was present in 16 of 23 DAP patients and 4 of 5 patients with IPMN. PMID: 19795908
21. Data show that the longer version of human QSOX1 protein (hQSOX1a) is a transmembrane protein localized primarily to the Golgi apparatus, and that hQSOX1a can act in vivo as an oxidase. PMID: 17331072
22. internal redox steps studied by mutagenesis PMID: 18393449
