Genetic Manipulation on a Massive Scale
MIT Biology Ph.D. Candidate Tim Wang Pioneers Genome-Wide Approach to Cancer Research
Tim Wang, a Ph.D. candidate at MIT, embarked on his academic journey six years ago with a dream to utilize a genetic approach to unravel the intricacies of cancer. His fascination with the field was piqued by the advent of CRISPR, a groundbreaking genome-editing method, during his tenure at MIT.
Wang was captivated by the prospect of working with some of the field's most advanced tools, including CRISPR. Using this system, he has developed a cutting-edge research technique that holds broad applications for studying numerous diseases.
Wang's passion for biomedical research was ignited during his childhood in California when he watched his father work with computers and, later, when his grandfather was diagnosed with non-Hodgkin's lymphoma. His academic career path shifted from computer science to bioengineering, enabling him to combine computational biology with molecular biology.
Wang's research at MIT, co-advised by biology professors David Sabatini and Eric Lander, was set in motion long before he arrived on campus. For decades, researchers had manipulated genes in model organisms using RNA interference, but this approach had limitations, as it often affected multiple genes indiscriminately.
When Wang first started at MIT, he worked on an alternative strategy for manipulating human genes. The strategy, developed at the Whitehead Institute, relied on a unique leukemia cell line with roughly half the genetic material of normal human cells. However, working with such an atypical cell line posed challenges in studying different types of cancer and various mutations.
The turning point came when CRISPR was introduced as a rapid and efficient method for editing human genes. Wang immediately saw the potential for CRISPR to revolutionize his research and consequently teamed up with Feng Zhang's lab at the Broad Institute to develop a new approach.
Wang's novel approach involves using CRISPR to target every gene simultaneously, allowing him to assess the function of every gene in the human genome and identify essential genes for cancer cell growth. This technique enables precisely targeted research on specific types of cancer and mutations, potentially providing valuable insights into new personalized cancer therapies.
The innovation has received widespread attention, with other research groups adopting it to study various diseases, such as Huntington's disease and aging. Moreover, the technique has piqued the interest of several pharmaceutical companies, offering a promising path toward developing effective drugs for cancer patients.
Looking ahead, Wang aims to pursue a postdoctoral research position in neuroscience, a field that promises new challenges and questions to tackle. As he embarks on this new journey, Wang remains committed to academic research and aspires to one day head his own lab.
