Research

Velculescu and members of his research group have pioneered approaches for discovering molecular alterations in human cancer and applying these discoveries to improve the diagnosis and treatment of cancer. In 1995 Velculescu developed SAGE (
serial analysis of gene expression Serial Analysis of Gene Expression (SAGE) is a transcriptomic technique used by molecular biologists to produce a snapshot of the messenger RNA population in a sample of interest in the form of small tags that correspond to fragments of those tr ...
), a gene expression technology for the global and quantitative measurement of gene activity. The SAGE approach provided some of the first insights into gene expression patterns in eukaryotic cells and the identification of gene expression patterns in human cancer. These studies led Velculescu to coin the term
transcriptome The transcriptome is the set of all RNA transcripts, including coding and non-coding, in an individual or a population of cells. The term can also sometimes be used to refer to all RNAs, or just mRNA, depending on the particular experiment. The ...
in a 1997 paper to describe the comprehensive gene expression patterns that could now be analyzed. SAGE contributed to the development of next-generation sequencing methods used for genome-wide expression analyses. In the early 2000s, Velculescu and members of his laboratory devised new technologies for characterizing the cancer genome. These included digital
karyotyping A karyotype is the general appearance of the complete set of chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is discerned by de ...
, which allows for quantitative characterization of amplifications and deletions at the DNA level. This approach provided the underlying methodology for next-generation sequencing analyses to detect chromosomal abnormalities in human cancer as well as in prenatal
genetic testing Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression, or ...
. In parallel, Velculescu was an early developer of methods for high-throughput sequencing of human cancer, which his group used to identify the PIK3CA gene as one of the most highly mutated cancer genes. Starting in 2005, Velculescu extended these approaches, and together with

In 2010, Velculescu and his group developed the PARE (personalized analysis of rearranged ends) technology that can help detect genomic tumor biomarkers circulating in the blood to enable the monitoring and personalized treatment of human cancer. Using this approach, his laboratory performed the first whole-genome analysis detecting chromosomal alterations in the blood of cancer patients.


Translational efforts

Velculescu co-founded the cancer genomics company Personal Genome Diagnostics (PGDx) in 2010 to bring individualized cancer genome analyses to patients, physicians, researchers and drug developers. PGDx was the first clinical laboratory to provide whole-exome sequencing for cancer patients in 2011.
