For recent graduate Rhea Martin, research is about connecting the pieces.
Rhea returned to Dr. Linda Chelico's (PhD) lab for a second consecutive summer, building on work she began as an undergraduate student.
After graduating this spring with a Bachelor of Science (Honours) degree in Biochemistry, Microbiology and Immunology, Rhea is continuing her research as a graduate student at USask this fall.
Her work initially focused on proteins that help the body defend itself against HIV-1. During the school year, Rhea became interested in how a related group of proteins may play a role in cancer and shifted her research focus.
Supported by the Diefenbaker Memorial Scholarship, Rhea’s summer project explored whether APOBEC3B may also promote cancer by affecting genes that control cell growth in estrogen receptor-positive breast cancer. The findings could reveal a new way that APOBEC3B contributes to cancer beyond its role in causing changes to DNA.
"I love watching the story come together. It isn't just doing the experiments, reading papers, analyzing data or communicating the findings. All of these components are needed for the scientific story to come together. Watching this happen in real time is what I find most exciting,” she said.
