The second sbv IMPROVER Challenge was in many ways more complex than the first, with more data to consider, in rather challenging settings. We were glad to see that the approach we refined for the previous challenge proved once more to be robust. Once again, sbv IMPROVER has proven itself to be unique in allowing us to identify which predictive techniques work best in specific, distinct settings, and at the same time giving us a perspective on the limitations of rodent models in the study of human biology.

On the Species Translation Challenge

The results from each sub-Challenge may have far reaching implications for scientists in many fields that use animal models to understand more about human biological systems. It is clear that from a computational biologists’ perspective, rodents and humans are indeed closer than we think. We have been delighted with the quality of submissions to the Species Translation Challenge. If the goal is to make meaningful predictions about human biology from data derived from rodent models, it is extremely important to carefully consider the specific characteristics of the experimental system and the biological mechanisms that may be impacted in order to identify the most adequate model systems for a given question.

On the Species Translation Challenge

Among the issues in our understanding of species translatability is the need to bridge the gap between informatics and real-world biology. sbv IMPROVER continues to provide valuable insights in this area, bringing together scientists that understand innovative techniques such as machine learning and neural network with molecular and cell biologists. In doing so the project addresses both the technical and biological challenges inherent in making predictions between species.

On the Species Translation Challenge

It is clearly very difficult to make direct predictions of human biology based on rodent models. However, we can see that relationships that hold within rodent gene-sets, identified through our computations, are themselves useful in helping us understand what happens in humans.

On the Species Translation Challenge

With a diminishing return on investment on drug development, translational modeling is becoming an increasingly important focus in the pharmaceutical industry. The ultimate power lies in being able to confidently verify translational concepts in order to build truly informative clinical models. The techniques used in the sbv IMPROVER Species Translation Challenge, both in terms of the submissions and the challenge design, are highly relevant in helping us achieve this goal.

On the Species Translation Challenge

The Species Translation Challenge invited us to ask: are rats and humans closer than we think? Based on our work on the second sub-Challenge, it seems that there may well be a closer relationship between rat and human than what is currently acknowledged. This is an exciting discovery, with potential implications across a number of fields, and one we look forward to exploring further.

The sbv IMPROVER Network Verification Challenge brought together scientists from around the world in many different disciplines to share their expertise in biological signaling. This allowed for specific feedback to refine the networks that does not exist in traditional scientific forums. Being able to have an active discussion with scientists who have studied these pathways their whole career was a stimulating experience that will enable us to more clearly and comprehensively describe the biology in these networks. Having both keynote speakers in a traditional speaker-audience format along with breakout sessions where everyone could voice their opinions made for a unique environment that allowed for a high amount of contribution from all participants at the meeting.

Under the umbrella of the sbv IMPROVER Network Verification Challenge, scientists from around the world are working together to build the most comprehensive and sophisticated models of COPDs that we have ever known. These models will be invaluable in assessing the mechanistic action of new drug compounds, and thereby expedite the drug discovery and development process. Beyond COPD, many of the models are relevant to other diseases too, and the implications for the advancement of healthcare across a number of fields are thus far reaching.

On the Network Verification Challenge

Building accurate biological maps is a complex process that requires continuous review to ensure all new discoveries are appropriately captured. The unique design of the sbv IMPROVER Network Verification Challenge allows us to build maps of cross-interacting factors (mediators, enzymes, receptors, signaling molecules etc), thereby helping us to understand basal and pathologic mechanisms as best as possible, and potentially to identify new pharmacological targets to treat disease.

On the Network Verification Challenge

The Network Verification Challenge demonstrates just how effective crowd-sourcing can be to build, test and validate complex biological models. We have used the outputs of the first stage of the Network Verification Challenge as the gold-standard for our own text mining evaluation campaign, which is being run as part of BioCreAtIvE (Critical Assessment of Information Extraction systems in Biology). With the Network Verification Challenge now attracting many more participants we are seeing an even greater level of granularity emerge. The robustness of the methodology, together with the high level of activity we are seeing in the challenge, means that the models can be used with confidence in a whole range of applications.

On the Network Verification Challenge

The first sbv IMPROVER challenge offered an excellent opportunity to test and develop different approaches to classifying clinical samples based on gene expression. We were hopeful that the challenge would inform our work in the prediction of adverse pregnancy outcomes and the results are looking very promising. Our analytical approach was designed to be robust enough to handle the different sources of non-biological variability in the data, while identifying small sets of biomarkers predictive for each of the diseases. Unlike most of the top ranked teams, two of the four models we proposed used information from as little as two genes instead of hundreds.
