Abstract
Systems toxicology marks an important stage in the evolution of toxicology. It combines the insights from traditional toxicology endpoints, high-throughput data, and quantitative analysis of large cause-and-effect molecular network models that provide the most mechanistic information in the interpretation of high-throughput data. Here, we show an example how pulmonary causal biological network models can be used in a meta-analysis of independent studies on engineered nanomaterials (ENM) to gain mechanistic insight into the similarities and differences of the ways the ENMs impact biological processes in the mouse lung. Meta-analyses using the lung network models could be used in various toxicological applications to find underlying trends in response to exposures, derive compound-specific mechanistic signatures, and translate between species.

Our RRPs

Reduced Risk Products (“RRPs”) is the term we use to refer to products that present, are likely to present, or have the potential to present less risk of harm to smokers who switch to these products versus continuing smoking. PMI has a range of RRPs in various stages of development, scientific assessment and commercialization. Our RRPs are smoke-free products that produce an aerosol that contains far lower quantities of harmful and potentially harmful constituents than found in cigarette smoke.
