"These tumors actually becoming something that's very, very
different in response to therapy. And this allows them then to
survive and adapt," says David Goode, regarding current studies
he's leading on cancer, specifically prostate. He adds that by
changing cell type, these cancer cells evade treatment by altering
what they need. He describes intricacies in cancer progression he's
learned through computational biology work that could inform better
treatment.
Listen and learn
- How his lab utilizes genetics biology and cancer evolution nature to figure out what makes some tumors more aggressive than others,
- Why this type of cancer genetics and genomics work offers evolutionary clues regarding resistance development,
- How prostate cancer cells transdifferentiate into a neuro endocrine cell type so that they don't need testosterone anymore, and
- What "signatures of loss of multicellularity" means and why his lab studies the process in cancer cells.
David Goode is group leader and faculty in the Computational
Biology Program with the Peter MacCallum Cancer Center in
Australia. His work engages the importance of genetics and
evolution in cancer through bioinformatics, genomics, molecular
evolution, and population genetics.
He and colleagues are trying to better understand the results of
cancer evolution. They use mathematical models where they can
stimulate tumor growth in simulations. This allows them to follow
progressions and different mutations and clonal populations over
changes in tumors at different points in time of therapy.
He gets specific about some of their cutting-edge techniques and
research. While they use whole genome sequencing or exome
sequencing, he adds that, "single cell technologies are really
powerful, and that's something we are looking to move into where
you can actually profile individual cells." For now, they also
utilize tools and analyses in their computational work to
understand how tumors become resistant to therapies. He adds, "if
we know that, then perhaps we can come up with better ways to treat
patients that will prevent the tumors from becoming resistant in
the first place."
