“That was mind-boggling, that bacteria could cause cancer,” Salama said. “...I thought, ‘Wow, I don’t know how I’m going to do it, but I’m going to study H. pylori.’”
Salama is also studying how other bugs in our body interact with H. pylori and whether that bacterial interplay could push an infected person toward developing gastric cancer.
Working with Fred Hutch basic scientist Dr. Gerry Smith, Salama also found that H. pylori needs to be able to repair its own damaged DNA to survive in the stomach. Her research team then found several small molecules that block that repair, which could make them excellent candidates as antibiotics. New drugs are urgently needed since antibiotic-resistant strains of H. pylori are common, and current treatments that are effective are difficult to administer in resource-poor regions, where infections are on the rise.
Salama said collaboration and a risk-taking culture have propelled her work at the Hutch. "Isolation really stifles creativity," she said. "But working together to blend creative approaches is encouraged here. I love that we're constantly getting reseeded with new ideas."
Taking chances and exploring unexpected research paths are the essence of good science, Salama said. "You have an idea to bring things together one way, but you don't know where things are going to go. Just starting the process is critical — if you never start, you'll never learn."
