Human Growth Factor+Neurotrophin+Cytokine Array-Test 40 Markers in on Assay

Sensitive, Specific and Cost Effective

Neuro-immuno and degenerative diseases and disorders commonly show dysregulation of Growth Factors and Cytokines. Using our Quantibody Neuroscience Arrays, we have measured the blood serum of clients with Neuro-inflammatory/immune response diseases/disorders including Autism Spectrum Disorder (ASD). Most showed lowered levels of Growth Factors/Neurotrophins and elevated levels of Inflammatory Response Cytokines.

In order to expand the number of biomarkers measured, we are pleased to announce the addition of our New Growth Factor+Neurotrophin+Cytokine Array. This will enable us to further determine the "finger prints" of these diseases/disorders at the protein level. This array includes: Immunogen: Amphiregulin, BDNF, bFGF, BMP-4, BMP-5, BMP-7, beta-NGF, EGF, EGFR, EG-VEGF (PK1), FGF-4,FGF-7 (KGF), GDF-15, GDNF, Growth Hormone, HB-EGF, HGF, IGFBP-1, IGFBP-2, IGFBP-3, IGFBP-4, IGFBP-6, IGF-1, Insulin, M-CSF R, NGFR (TNFRSF16), NT-3, NT-4, Osteoprotegerin (TNFRSF11B), PDGF-AA, PLGF, SCF, SCF R (CD117/c-kit), TGF alpha, TGF beta 1, TGF beta 3, VEGF-A, VEGFR2, VEGFR3 and VEGF-D.

I will continue to post testing results here.

Autism Spectrum Disorder and Biomarkers

We used our IFN-gamma and BDNF Sandwich Elisa Kits to test the levels of these biomarkers in the blood serum of 2 individuals with Austism Spectrum Disorder. We anticipated  that BDNF would be significantly up or down regulated and IFN-gamma up regulated as confirmed by the literature. see 10.1371/journal.pone.0020470 , DOI: 10.1371/journal.pone.0020470 and DOI: 10.1111/acps.12071.

Our testing results showed:
Figure 1: ASD and Biomarker Levels

Based on these initial findings we are developing a custom Quantibody® Antibody Array designed for the fine tuned testing of individuals with ASD. The biomarkers included in the array will be: HSP70, TGF-beta2, 
Caspase-7, IFN-gamma and BDNF.

Figure 2: ASD Markers vs Controls

These panels will enable us to determine the severity of ASD. From the results, we will be working with our collaborators to determine potential cell based therapies for improving the symptom and behaviors of ASD sufferers. As part of the therapeutic regimes the panels can then be used check on progress towards "wellness". 

This a key initiative for us in 2014 so stay tuned.

Nestin as a Marker for Astrocytomas

I recently highlighted the growing parade of pubs referencing use of our reagents for Cancer Research.

I would like to add a new one. Angogenesis of Astrocytomas show stem like properties. This makes our Nestin Antibodies excellent markers.

J H Tchaicha, A K Mobley, M G Hossain, K D Aldape and J H McCarty. A mosaic mouse model of astrocytoma identifies αvβ8 integrin as a negative regulator of tumor angiogenesis. Oncogene , (7 June 2010) doi:10.1038/onc.2010.199...chicken anti-Nestin IgY (Neuromics, Edina, MN, USA)...

Abstract: Angiogenesis involves a complex set of cell–cell and cell–extracellular matrix (ECM) interactions that coordinately promote and inhibit blood vessel growth and sprouting. Although many factors that promote angiogenesis have been characterized, the identities and mechanisms of action of endogenous inhibitors of angiogenesis remain unclear. Furthermore, little is known about how cancer cells selectively circumvent the actions of these inhibitors to promote pathological angiogenesis, a requisite event for tumor progression. Using mosaic mouse models of the malignant brain cancer, astrocytoma, we report that tumor cells induce pathological angiogenesis by suppressing expression of the ECM protein receptor αvβ8 integrin. Diminished integrin expression in astrocytoma cells leads to reduced activation of latent TGFβs, resulting in impaired TGFβ receptor signaling in tumor-associated endothelial cells. These data reveal that astrocytoma cells manipulate their angiogenic balance by selectively suppressing αvβ8 integrin expression and function. Finally, these results show that an adhesion and signaling axis normally involved in developmental brain angiogenesis is pathologically exploited in adult brain tumors.
