Human Roundabout, Axon Guidance Receptor, Homolog 4 (Drosophila) (ROBO4) interaction partners

1. Low expression level of ROBO4 is associated with evasive resistance and disease progression in cancer.

2. GM-CSF and IL-1beta. Taken together, we demonstrated novel Robo4 functions in inflammation, i.e., it promotes IL-6 production by endothelial cells and immune cells via crosstalk.

3. Results show that hyperglycemia-induced upregulation of Robo4 in retinal endothelial cells is directly mediated by transcription factor SP1 which increases the transcription of Robo4 via an additional binding site in Robo4 promoter. SP1/Robo4 can regulate the migration, monolayer permeability and angiogenesis of retinal endothelial cells under hyperglycemic conditions.

4. Overexpression of Roundabout4 is associated with glioma.

5. there was a increase in Robo4 expression under hyperglycemic conditions, while there was a decrease under hypoxic and combined hypoxic and hyperglycemic conditions, suggesting Robo4 might play different roles in various stages of diabetic retinopathy

6. These results suggest that Slit2/Robo1 binding exerts an effect on cell migration, which is negatively regulated by Robo4, and Robo1 may function by interacting with CdGAP in HUVECs.

7. results indicate that AP-1 complexes regulate Robo4 gene expression in endothelial cells

8. BM Robo4 expression can serve as a new biomarker to predict clinical outcomes in AML patients and Robo4 may serve as a potential therapeutic target in patients with higher Robo4 expression.

9. Robo4 suppressed glioma-induced endothelial cell proliferation, migration and tube formation in vitro by inhibiting VEGR2-mediated activation of PI3K/AKT and FAK signaling pathways.

10. Increased or decreased expression of Robo4 by stimulation or knockdown of HIF-1alpha suggesting that Robo4 is positively regulated by HIF-1alpha under normoxic and hypoxic conditions in microvascular endothelial cells in vitro.

11. Plasma Robo4 levels are increased, transiently, following cardiac surgery requiring CPB

12. This study demonistrated that roundabout 4 regulates blood-tumor barrier permeability through the modulation of ZO-1, Occludin, and Claudin-5 expression.

13. Endothelial cell-specific DNA methylation pattern of the Robo4 proximal promoter is determined during cell differentiation and contributes to regulation of EC-specific Robo4 gene expression.

14. SLIT3-ROBO4 activation promotes vascular network formation in human engineered tissue and angiogenesis in vivo.

15. Slit2-Robo4 is a key regulator of endothelial inflammation, and its dysregulation during endotoxemia is a novel mechanism for LPS-induced vascular pathogenesis.

16. Here I will discuss the regulation mechanism of Robo4 gene expression by transcription factors and epigenetic control. [Review]

17. SiRNA knockdown of Robo4 in pulmonary microvascular endothelial cells prevented Slit2 inhibition of Andes virus induced permeability demonstrating that Robo4 receptors determine pulmonary microvascular endothelial cells responsiveness to Slit2

18. targeting Slit2/Robo4 signaling may protect the integrity of the lymphatic barrier and limit the dissemination of HIV in the host.

19. Protein expression of Slit2/3 and Robo1/4 was also identified in OVCAR-3 and SKOV-3 cells.

20. REVIEW: Robo4-dependent Slit signaling stabilizes the vasculature during pathologic angiogenesis and cytokine storm

Mouse (Murine) Roundabout, Axon Guidance Receptor, Homolog 4 (Drosophila) (ROBO4) interaction partners

1. Robo4 inhibits angiogenesis and vessel permeability independently of its cytoplasmic domain. Robo4 deletion enhances permeability and revascularization in oxygen-induced retinopathy (OIR) and accelerates cutaneous wound healing.

2. endothelial Robo4 signaling is important for suppressing breast cancer growth and metastasis, and it can be targeted (enhanced) by administrating a small molecular drug.

3. Robo4 vaccines induce antibodies that retard tumor growth.

4. Robo4 and Src family kinases are involved in the mechanisms of embryonic vascular defects caused by the Hrt/Hey deficiency.

5. These results clearly indicate that Robo4 plays a role in hematopoietic stem cells trafficking such as bone marrow homing and peripheral mobilization.

6. our results showed an important role of Robo4 in the regulation of cortical radial migration through Slit-dependent and -independent mechanisms

7. Data found that expression of Slit2 and SDF1 were dynamically regulated in mesenchymal stem cells and OBC-like populations following radiation, while Robo4 expression was restricted to endothelial cells.

8. augmenting the host Robo4/Slit2 system could provide a useful therapeutic approach to control pathological angiogenesis associated with HSV induced stromal keratitis

9. Robo4 specifically binds to UNC5B, a vascular Netrin receptor, revealing unexpected interactions between two endothelial guidance receptors.

10. Activating with the soluble ligand Slit an endothelium-specific, Robo4-dependent signaling pathway that strengthens the vascular barrier, diminishing deleterious aspects of the host's response to the pathogen-induced cytokine storm.

11. enhanced growth of blood vessels in Robo4(-/-) endothelium is due to activation of vascular endothelial growth factor (VEGF)-R2 signaling through the Src and FAK kinases.

12. Robo4 is a bona fide member of the Robo family and may provide a repulsive cue to migrating endothelial cells during vascular development.

13. Robo4 is expressed in hematopoietic stem cells (HSC), and Robo4/Slit2 signaling may play a role in HSC homeostasis in the bone marrow niche.

14. Robo4 mRNA level decreases during vascular decline in pulmonary fibrosis.
