Explanation and Summary of What the above Studies are all about.
A research team funded by NIH’s National Cancer Institute—the Clinical Proteomic Tumor Analysis Consortium (CPTAC)—set out to build an expansive tumor proteogenomic dataset based on studies of more than 1,000 tumors across 10 cancer types. They described their project and demonstrated its ability to give new insights in a series of papers published in Cell and Cancer Cell on August 14, 2023.
In the first paper, the researchers examined cancer-driving mutations across the different cancer types. They were able to detect distinct patterns in how these mutations impact various aspects of cell function.
Another paper examined how protein modifications, called post-translational modifications, affect cell function. The team identified shared patterns of protein regulation involved in cancer processes across different tumor types. These patterns affect DNA repair, metabolism, and immunity.
A third paper examined patterns of DNA methylation, a type of reversible modification that regulates gene activity. The team identified changes that altered how RNA and proteins were made from crucial cancer-associated genes. They also found methylation patterns associated with various tumor characteristics. These findings, taken together, included many new insights into how cancer develops and suggest potential novel targets for therapies.
“These articles demonstrate the impact of studying both the genetic and protein-related aspects of cancer, and they show how scientists from different fields can work together,” says Dr. Ana I. Robles, Program Director at NCI’s Office of Cancer Clinical Proteomics.
