Traditional reductionist approaches play a crucial role in our understanding of biology and medicine, but they cannot explain the full complexity of biological phenomena and human disease. Systems biology combines recent high-throughput profiling technologies—such as transcriptomics, proteomics, and metabolomics—with computational modeling to capture, summarize, and understand this complexity. In this article, we provide a detailed overview of these experimental profiling technologies and computational modeling approaches. Several case studies illustrate how system approaches are already effectively used in toxicology assessment, drug development, diagnostics, and personalized medicine. Overall, this article provides the foundations to further integrate systems biology approaches into biomedical research.

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.
