Stroma Liquid Biopsy - The Next Wave Of Proteomic Profiles For Cancer Biomarkers

While the landscape of cancer-associated DNA mutations has supported the initial concepts for liquid biopsy, it is now overwhelmingly apparent that throughout cancer progression, there are necessary adaptive microenvironments to support metastatic disease. We now present evidence that some of the essential interactions between stroma and proliferating cells can in part, be monitored through the protein response that tracks into the vascularized tumor and re-proportions the extracellular proteins (serum) found in the general blood circulation. These proteomic patterns can now be reported as a Stroma Liquid Biopsy™ which we are launching as a business unit called Rakta.

Is there a common systemic response to cancer? Coagulation, Complement Cascade, Acute Phase Inflammation

Our commercial goal is to associate this knowledge and data to establish relationships with client supplied samples characterized for progressive disease or response to therapies, ultimately achieving biomarkers useful in the clinic. We achieve these goals through partnerships and collaborations in the oncology field, but the discovery patterns can be applied to other disease pathologies.
