  • ||||||||||  Journal:  Influence of traumatic brain injury on extracellular tau elimination at the blood-brain barrier. (Pubmed Central) -  Feb 22, 2022   
    Lastly, angiopoietin-1, a mural cell-derived protein governing endothelial Mfsd2a expression, was secreted from r-mTBI cerebrovessels to a greater extent than r-sham animals. Altogether, in the chronic phase post-injury, release of angiopoietin-1 from degenerating mural cells downregulates caveolin-1 expression in brain endothelia, resulting in decreased tau elimination across the BBB, which may describe the accumulation of tau species in the brain following head trauma.
  • ||||||||||  Journal:  Endothelial Dysfunction in Fabry Disease Is Related to Glycocalyx Degradation. (Pubmed Central) -  Feb 17, 2022   
    We conclude that chronic inflammation, including the release of heparanases, appears to be responsible for the degradation of the endothelial glycocalyx and may explain the endothelial dysfunction in FD. This process is partially reversible by FD-specific and anti-inflammatory treatment, such as targeted protective Tie2 treatment.
  • ||||||||||  Clinical, Journal:  Circulating lncRNAs HIF1A-AS2 and LINLK-A: Role and Relation to Hypoxia-Inducible Factor-1α in Cerebral Stroke Patients. (Pubmed Central) -  Feb 8, 2022   
    Serum levels of phosphatidylinositol 3-kinase (PI3K), phosphorylated-Akt (p-Akt), vascular endothelial growth factor (VEGF), and angiopoietin-1 (ANG1) as well as their receptors, malondialdehyde (MDA), and total antioxidant capacity (TAC) were significantly increased, whereas brain-derived neurotrophic factor (BDNF) levels were significantly decreased particularly in hemorrhagic stroke versus ischemic groups. Eventually, these findings support the role of lncRNAs HIF1A-AS2 and LINK-A as well as HIF1-α in activation of angiogenesis, neovascularization, and better prognosis of stroke, especially the hemorrhagic type.
  • ||||||||||  Clinical, Journal:  Mapping Angiopoietin1 expression in the developing and adult brain. (Pubmed Central) -  Jan 28, 2022   
    Our study suggests that severely ill patients with HFpEF and diabetes synthesize and release a greater abundance of NETs while Ang1 exocytosis is independent of NETs synthesis. No abstract available

  • ||||||||||  Journal:  Biomimetic Hydrogels Loaded with Nanofibers Mediate Sustained Release of pDNA and Promote In Situ Bone Regeneration. (Pubmed Central) -  Dec 22, 2021   
    The cell experiment shows that this system can significantly promote MC3T3-E1 cell attachment, proliferation, as well as osteogenic-related and angiogenic-related genes expression of MC3T3-E1 cells. Moreover, the in vivo results show that the composite scaffold with activated gene fibers can significantly promote osteogenesis and vascularization leading to favorable capacity of bone regeneration, meaning that the resulting biomimetic composite hydrogel scaffolds are excellent candidates for bone repair materials.
  • ||||||||||  Journal:  Inhibition of Notch signaling pathway reduces angiogenesis in hypertrophic scar. (Pubmed Central) -  Dec 17, 2021   
    The expressions of angiogenesis-related factors appeare to be up-regulated during the formation of proliferative scar. When the Notch signaling pathway is inhibited, the up-regulated angiogenic factors show a decreasing trend and the proliferative scar is alleviated, which suggests that Notch signaling pathway may affect the formation of hyperplastic scar by regulating the expression of angiogenic factors.
  • ||||||||||  Preclinical, Journal:  Effects of Different Target Temperatures on Angiogenesis and Neurogenesis Following Resuscitation in a Porcine Model After Cardiac Arrest. (Pubmed Central) -  Dec 17, 2021   
    When the Notch signaling pathway is inhibited, the up-regulated angiogenic factors show a decreasing trend and the proliferative scar is alleviated, which suggests that Notch signaling pathway may affect the formation of hyperplastic scar by regulating the expression of angiogenic factors. Lower target temperature showed greater protective effects against cerebral injuries after CPR, and the improved neurological outcomes after TTM may be associated with decreased expression of pro-inflammatory cytokines and increased expression of blood-brain barrier and neurogenesis regulatory factors in this porcine model of CA following resuscitation.
  • ||||||||||  Preclinical, Journal:  Treatment with an Angiopoietin-1 mimetic peptide promotes neurological recovery after stroke in diabetic rats. (Pubmed Central) -  Dec 16, 2021   
    Lower target temperature showed greater protective effects against cerebral injuries after CPR, and the improved neurological outcomes after TTM may be associated with decreased expression of pro-inflammatory cytokines and increased expression of blood-brain barrier and neurogenesis regulatory factors in this porcine model of CA following resuscitation. Delayed VT treatment (24 h after stroke) significantly improves neurological function, promotes vascular and white matter remodeling, and decreases inflammation in the ischemic brain after stroke in T1DM rats.
  • ||||||||||  Journal:  Regulatory role of TIGAR on endothelial metabolism and angiogenesis. (Pubmed Central) -  Dec 16, 2021   
    In addition, knockout of TIGAR blunted TAC-induced cardiac hypertrophy and dysfunction seen in the WT mice. In conclusion, knockout of TIGAR improves endothelial angiogenetic capabilities by enhancing the endothelial glycolytic function, mitochondrial respiration, and proangiogenic signaling, which leads to increased coronary capillary density and vascular function and protects against chronic stress.
  • ||||||||||  Review, Journal:  Update Overview of the Role of Angiopoietins in Lung Cancer. (Pubmed Central) -  Dec 6, 2021   
    The present review focuses on the clinical impact of the Angiopoietin-1, Angiopoietin-2, and Angiopoietin-4 levels in patients diagnosed with NSCLC, emphasizing the interaction between them, and how they affect the development, progression, and metastasis of lung disease. Finally, it estimates the role of angiopoietins levels in the effective therapy of lung cancer patients.

    The new Hepta-ANG1 fusion is easy to produce and displays remarkable stability with high multimericity that can potently activate Tie2. It could be a new candidate ANG1 mimetic therapy for treatments of inflammatory vascular leak, such as acute respiratory distress syndrome and sepsis.
  • ||||||||||  Biomarker, Review, Journal, Tumor microenvironment:  Targeting Tie2 in the Tumor Microenvironment: From Angiogenesis to Dissemination. (Pubmed Central) -  Nov 29, 2021   
    Therefore, Ang-Tie2 signaling functions as an angiogenic switch during tumor progression and metastasis. Here we review the recent advances and complexities of targeting Tie2 signaling in the tumor microenvironment as a possible anti-angiogenic, and anti-metastatic, therapy and describe its use in combination with chemotherapy.
  • ||||||||||  Clinical, Journal:  Exercise Training Enhances Angiogenesis-Related Gene Responses in Skeletal Muscle of Patients with Chronic Heart Failure. (Pubmed Central) -  Nov 16, 2021   
    Changes in capillary-to-fibre ratio were found to be strongly associated with Tie2 and HIF-1α expression. This was the first study demonstrating that both HIIT and combined HIIT with strength training enhanced similarly the expression profile of angiogenic factors in skeletal muscle of HF patients, possibly driving the angiogenic program in the trained muscles, although those gene expression increases were found to be only partially related with muscle capillarization.
  • ||||||||||  Avastin (bevacizumab) / Roche
    Journal:  Interleukin-6 as an enhancer of anti-angiogenic therapy for ovarian clear cell carcinoma. (Pubmed Central) -  Nov 11, 2021   
    Although bevacizumab (Bev) is a widely used anti-angiogenic agent for EOC, the efficacy of Bev and the role of IL-6 in modulating angiogenesis in OCCC are unknown. We performed tube formation assays using human umbilical vein endothelial cells (HUVEC) cultured in OCCC cell-conditioned medium and using cells directly co-cultured with OCCC cells...Finally, depletion of Ang1 abrogated the effects of IL-6 inhibition on Bev activity, demonstrating that IL-6 supports the anti-angiogenic activity of Bev by suppressing Ang1 expression and promoting dependence on VEGF for angiogenesis. Altogether, our data suggest that OCCC tumors with high IL-6 levels are candidates for Bev therapy.

    We also discovered the formation of endothelium within the islets under Ang2 stimulation. These results strongly suggest that angiopoietin acts as a signaling molecule to endorse in vitro islet development from iPSCs.
  • ||||||||||  Journal:  Associations of angiopoietins with heart failure incidence and severity. (Pubmed Central) -  Nov 4, 2021   
    Ang2 was associated with incident heart failure or death among adults without cardiovascular disease at baseline and with disease severity in individuals with existing heart failure. Our findings that Ang2 is elevated prior to disease onset and that elevations reflect disease severity, suggest Ang2 may contribute to heart failure pathogenesis.
