New technology has enabled researchers to create a “genomic atlas of the human plasma proteome,” according to an article published in Nature.
The researchers identified nearly 2000 genetic associations with close to 1500 proteins, and they believe these discoveries will improve our understanding of diseases and aid drug development.
“Compared to genes, proteins have been relatively understudied in human blood, even though they are the ‘effectors’ of human biology, are disrupted in many diseases, and are the targets of most medicines,” said study author Adam Butterworth, PhD, of the University of Cambridge in the UK.
“Novel technologies are now allowing us to start addressing this gap in our knowledge.”
Dr Butterworth and his colleagues used an assay called SOMAscan (developed by the company SomaLogic) to measure 3622 proteins in the blood of 3301 people. The team then analyzed the DNA of these individuals to see which regions of their genomes were associated with protein levels.
In this way, the researchers found 1927 significant associations between 1478 proteins and 764 genomic regions. These findings are publicly available via the University of Cambridge website.
The researchers said one way to use this information is to identify biological pathways that cause diseases.
“Thanks to the genomics revolution over the past decade, we’ve been good at finding statistical associations between the genome and disease, but the difficulty has been then identifying the disease-causing genes and pathways,” said study author James Peters, PhD, of the University of Cambridge.
“Now, by combining our database with what we know about associations between genetic variants and disease, we are able to say a lot more about the biology of disease.”
In some cases, the researchers identified multiple genetic variants influencing levels of a protein. By combining these variants into a “score” for that protein, they were able to identify new associations between proteins and disease.
The team also said the proteomic genetic data can be used to aid drug development. In addition to highlighting potential side effects of drugs, the findings can provide insights on protein targets of new and existing drugs.
By linking drugs, proteins, genetic variation, and diseases, the researchers have already suggested existing drugs that could potentially be used to treat different diseases and increased confidence that certain drugs currently in development might be successful in clinical trials.
“Our database is really just a starting point,” said study author Benjamin Sun, an MB/PhD student at the University of Cambridge.
“We’ve given some examples in this study of how it might be used, but now it’s over to the research community to begin using it and finding new applications.”
The research was funded by MSD, National Institute for Health Research, NHS Blood and Transplant, British Heart Foundation, Medical Research Council, UK Research and Innovation, and SomaLogic.
