Major Vault Protein (MVP) ELISA Kits

Human Major Vault Protein (MVP) interaction partners

1. Study shows that adipocytes induce major vault protein (MVP)-related multidrug-resistant phenotype in breast cancer cells, which could contribute to obesity-related chemoresistance. In a series of human breast tumors, a gradient of MVP expression was observed, and it was higher at the invasive front, where tumor cells are at close proximity to adipocytes, highlighting the clinical relevance of these results.

2. Study identified major vault protein (MVP) as a suppressor for NF-kappaB signaling in macrophages. Up-regulation of MVP expression in macrophages of visceral adipose tissues was correlated with obesity in both humans and mice, suggesting that MVP be involved in obesity-associated inflammation.Results demonstrate that macrophage MVP constitutes a key constraint of NF-kappaB signaling thereby suppressing metabolic diseases.

3. B7-H3 is associated with the major vault protein (MVP) and activates MEK through MVP-enhancing B-RAF and MEK interaction. B7-H3 expression increases stem cell population by binding to MVP which regulates the activation of the MAPK kinase pathway. Depletion of MVP blocks the activation of MEK induced by B7-H3 and dramatically inhibits B7-H3 induced stem cells.

4. KPNA7 binding and nuclear transfer was validated for two proteins, MVP and ZNF414. MVP and ZNF414 have a key role in the regulation of pancreatic cancer cell growth.

5. Knockout of MVP leads to miR-193a accumulation in the exosomal donor cells instead of exosomes, inhibiting tumour progression.

6. The expression levels of LRP and GSTP1 in primary epithelial ovarian cancer were the highest, followed by borderline adenoma tissues, and lowest levels in benign tumor tissues. The difference between resistant gene negative-expression and positive-expression of chemotherapy efficiency, disease free survival time, and recurrence time were statistically significant.

7. KIF4A promotes drug resistance of lung adenocarcinoma cells through transporting LRP-based vaults along microtubules towards the cell membrane

8. Major vault protein is important in the drug resistance of cancer cells, but it requires the presence of vPARP for full activity

9. involved in doxorubicin resistance of non-small cell lung cancer

10. Study found significant upregulation of MVP and BCRP whereas MRP1 and UGT1A4 were unaltered in drug resistant epilepsy brains. While upregulation of BCRP was significantly higher in mesial temporal lobe epilepsy (9.34+/-0.45; p<0.05), upregulation of MVP was significantly higher in focal cortical dysplasia (2.94+/-0.65; p<0.01).

11. Taxus chinensis var.-mediated downregulation of MRP1, MDR1, and LRP might contribute to the reversal of drug resistance in non-small cell lung cancer stem cells.

12. We believe that for the first time, genetic variants at XRCC6 and MVP genes are associated with risk of more aggressive disease, and would be taken into account when assessing the malignancy of prostate cancer

13. MVP genetic polymorphisms and haplotypes may not be associated with drug resistance of partial epilepsy in the Chinese Han population.

14. NSCLCs [ non-small cell lung cancer ] expressing P-gp [P-glycoprotein ]/LRP [ lung resistance-related protein] bear the EGFR [epidermal growth factor receptor] mutation in exon 19 or 21 easily.

15. The association of MVP amplification and PTEN deletion could be a potential biomarker in glioblastoma.

16. Bag3-MVP is an important complex that regulates a potent prosurvival signaling pathway and contributes to chemotherapy resistance in breast cancer

17. LDL increases ABCB1, ABCC1, and LRP expression in a human doxorubicin-resistant uterine sarcoma cell line.

18. Study demonstrates that vaults have a tumour-promoting potential by stabilizing EGFR/PI3K-mediated migration and survival pathways in human glioblastoma.

19. USF1 binding to an E-box element may be critical for basal MVP promoter activation.

20. hyperosmotic stress upregulates Sp1 expression levels by inhibiting ubiquitination through the activation of JNK, and the induction of Sp1 expression directly enhances MVP transcription.

Mouse (Murine) Major Vault Protein (MVP) interaction partners

1. Study identified major vault protein (MVP) as a suppressor for NF-kappaB signaling in macrophages. Both global and myeloid-specific MVP gene knockout aggravates high-fat diet induced obesity, insulin resistance, hepatic steatosis and atherosclerosis in mice. Results demonstrate that macrophage MVP constitutes a key constraint of NF-kappaB signaling thereby suppressing metabolic diseases.

2. plays major role in anti-viral immunity

3. MVP may fine-tune SR-A activity in macrophages which contributes to the development of atherosclerosis

4. MVP is hijacked by L. monocytogenes in order to counteract the autophagy process, a finding that could have major implications in deciphering the cellular role of vault particles.

5. These results suggest that up-regulation of MVP in multi-drug resistance (MDR) may involve chromatin remodeling.

6. Results suggest that major vault protein functions as a novel scaffold protein for both SHP-2 and Erk.

7. results suggest that MVP makes a substantial contribution to epithelial cell-mediated resistance to infection

8. The crystal structure of the vault particle solved at 8 A resolution, together with the 2.1-A structure of the seven N-terminal domains (R1-R7) of MVP, provide an explanation for a reversible dissociation induced by low pH.

Zebrafish Major Vault Protein (MVP) interaction partners

1. MVP is beneficial for functional recovery and axonal regrowth after spinal cord injury in adult zebrafish.

Purple Sea Urchin (Strongylocentrotus purpuratus) Major Vault Protein (MVP) interaction partners

1. structure and cellular localization during embryonic development; findings indicate a dramatic relocalization of MVP from the cytoplasm to the nucleus during sea urchin embryogenesis
