Seven Bridges & e-NIOS Partnership to Break the Biomarker Bottleneck



PR Newswire

Cambridge, Mass. and Athens, Greece., Sept 11, 2018. Seven Bridges, the leading biomedical data platform and analytics company, and e-NIOS, a biological knowledge discovery start-up, announced a strategic partnership towards data-driven discovery of biomarker signatures. Derivation of robust biomarkers from next generation sequencing and multi-omic data is currently a major bottleneck in precision medicine initiatives. This bottleneck continues to limit the transformation of genomic information into biomedical insights that will improve clinical outcomes through more efficient drug target discovery and more effective patient stratification.

Together, we are leveraging machine learning and physiology to improve and partially automate interpretation of potential biomarkers. Currently, interpretation is largely performed manually, relying on expert decisions. Human experts are both costly and inconsistent. Our partnership will develop efficient and standardized interpretation frameworks which harness the inherent complexity of molecular networks. This partnership has the potential to shift from listing all statistical correlations towards focusing on a smaller set of causal associations.

e-NIOS’ innovative technology enables unsupervised, intelligent translation of -omics data through BioInfoMiner, a cloud platform that resolves biological complexity and derives molecular signatures suitable for data-driven interpretation in different conditions, physiological states and datasets. Additionally, it allows the integration of different -omic layers (genomic, epigenomic, transcriptomic, proteomic, variants). BioInfoMiner can also drive discovery in studies related to plant and microbial systems.

According to e-NIOS’ co-founder Aristotelis Chatziioannou (CEO), “e-NIOS and Seven Bridges share the same vision for data-driven, streamlined computational genomics, integrating all steps from raw data to actionable biological interpretation. The Seven Bridges Platform is a valuable, high-performance cloud environment for the deployment of complex workflows and streamlined processing of massive, genomic datasets. Seven Bridges has been an excellent technological partner for our company as we work together to enable innovative, automated, data-driven biomarker industrial services and applications in the area of precision medicine.”
As Brandi Davis-Dusenbery, CEO of Seven Bridges, explained, “e-NIOS’ technology has the unique ability to combine biological network information with data-driven models. Here we bring together the technical and scientific strengths of both companies to provide a complete solution for the prediction of biomarker associations from raw data. Our strategic partnership supports Seven Bridges’ mission to connect the world’s biomedical information and rapidly transform it into actionable information.”

New paper involving BioInfoMiner analysis validates proteostasis imbalance as a driver of tumor aggressiveness in Glioblastoma (EMBO Mol. Med.)

Proteostasis imbalance is emerging as a major hallmark of cancer, driving tumor aggressiveness. Evidence suggests that the endoplasmic reticulum (ER), a major site for protein folding and quality control, plays a critical role in cancer development. This concept is valid in glioblastoma multiform (GBM), the most lethal primary brain cancer with no effective treatment.

It was previously demonstrated that the ER stress sensor IRE1α (referred to as IRE1) contributes to GBM progression. The new study entitled “Dual IRE1 RNase functions dictate glioblastoma development” published in EMBO Molecular Medicine provides the first demonstration of a dual role of IRE1 downstream signaling in cancer and opens a new therapeutic window to abrogate tumor progression.

BioInfoMiner analysis was employed in order to define specific IRE1‐dependent gene expression signatures that were confronted to human GBM transcriptomes and shed light to the antagonistic roles of XBP1 mRNA splicing and RIDD on tumor outcomes, mainly through selective remodeling of the tumor stroma.

The research was carried out by an international consortium with the participation of e-NIOS, including among others Université de Bordeaux, Université de Rennes 1, University of Ireland Galway, University of Chile, INSERM, CNRS, National Hellenic Research Foundation and Harvard School of Public Health.


e-NIOS is a partner of the international INNOCENT project, with the aim to develop an innovative multifunctional nano-pharmaceutical to overcome the low efficacy and frequent relapses in breast cancer treatment. The use of nano-based delivery systems, together with the benefits of a new generation of epi-drugs and the emergence of robust biomarker data, will help to advance personalized-targeted therapy and the efficacy of treatment for breast and other cancers. The proposed nano-drug will integrate the diagnostic and therapeutic functions within a single nanostructure.

BioInfoMiner elucidates the role of the early secretory pathway in SARS-CoV-2 infection


Here, we analyze and discuss the contribution of the molecular machines operating in the early secretory pathway in the biogenesis of SARS-CoV-2 and their relevance for potential antiviral targeting. The fact that these molecular machines are conserved throughout evolution, together with the redundancy and tissue specificity of their components, provides opportunities in the search for unique proteins essential for SARS-CoV-2 biology that could also be targeted with therapeutic objectives. Finally, we provide an overview of recent evidence implicating proteins of the early secretory pathway as potential antiviral targets with effective therapeutic applications.

The journeys of CoV-2 in the host cell. Coronavirus infection starts with the binding of the spike protein to cognate receptors. This drives conformational changes that promote fusion of the viral particle with the host cell’s plasma membrane. Once in the cytoplasm, viral particles are uncoated, and the viral RNA genome is translated, producing two polyproteins (pp1a and pp1ab). These polypeptides are proteolytically processed by host and viral proteases, generating nonstructural proteins (nsps). nsps assemble to form the replicase (R), which together with pp1a/pp1ab produces the replicase–polymerase complex. Replicase polymerase complex is responsible for the replication of the viral genome and for the production of subgenomic RNAs. The latter are translated to form structural proteins nucleocapsid (N), spike (S), membrane (M), and envelope (E). In addition to these genomic elements shared by other CoVs, the SARS-CoV-2 genome also contains eight ORFs coding for accessory proteins. Structural proteins are subjected to diverse posttranslational modifications in the ER and Golgi compartments, including disulfide bond and formation N- and O-glycosylation. Structural proteins concentrate in the ERGIC, where they assemble around the genome–nucleocapsid complexes. Mature virions are packed and budded in smooth-walled vesicles and then transported along downstream organelles of the exocytic pathway.

The molecular mechanisms underlying inflammatory bowel diseases remain currently not completely understood, and therapeutic options are scarce.

Herein, we have identified that a normally endoplasmic reticulum resident protein, AGR2, exhibits tightly regulated secretion mechanisms that are perturbed in Crohn’s disease. We demonstrate that the extracellular release of AGR2 leads to the chemoattraction of monocytes, thereby suggesting extracellular AGR2’s pro‐inflammatory functions, that can be blocked using specific antibodies.

As a consequence, this discovery could represent an appealing therapeutic approach to attenuate the inflammatory burden in Crohn’s disease.
