News — GRAND RAPIDS, Mich. (May 11, 2023) — , and , will co-lead a collaborative project supported by the Somatic Mosaicism across Human Tissues (SMaHT) Network, a new $140 million National Institutes of Health-led effort to better understand the genetic differences between individual cells and tissues in the body.
Somatic mosaicism occurs when DNA, which houses the genetic code, accumulates slight changes throughout a person’s lifetime.
Some variations may impede cells’ ability to function. Somatic mosaicism is a key contributor to cancer, but its role in other diseases is not well understood.
SMaHT aims to identify and catalog these somatic variants in different individuals and enable new research into development, aging and a host of disorders.
Together, Van Andel Institute and Washington University will serve as one of five SMaHT-supported Genome Characterization Centers, which will conduct leading-edge genomic analysis for the network.
Wang will serve as the project’s director; Shen will serve as co-director. The project is supported by a $15 million grant from the NIH Common Fund as part of SMaHT.
“We all carry such genetic mosaicism in our bodies, but the extent and implications of these variations remain unclear. Establishing an accurate picture of its role in the body is a massive undertaking that only can be achieved through collaboration,” Shen said. “I am thrilled to partner with Dr. Wang and the SMaHT Network, and look forward to contributing to a fuller understanding of this important and yet very much uncharted aspect of our cells.”
In total, the NIH Common Fund issued 22 awards to establish the SMaHT Network. The project is akin to other large-scale NIH-supported projects such as the , a 13-year endeavor that resulted in the first full blueprint of the human genome.
Shen is an internationally recognized expert in bioinformatics and epigenetics, the study of changes to DNA that do not alter the DNA sequence itself. She was a long-time member of , an NIH-led collaborative effort to molecularly map 33 different cancer types. TCGA ended in 2018 with the publication of its , a comprehensive resource for scientists seeking to understand how and why cancer develops. Shen is a current member of the National Cancer Institute’s a successor to TCGA that develops new tools to assist in the analysis of data.
