Johnson's team discovered that the parasite, Trichomonas vaginalis, secretes a protein that stimulates the growth of prostate cells and also induces an inflammatory response, which the researchers suspect enhances the cells' progression to tumor cells.
According to the
"Trichomoniasis can be successfully treated with a single dose of antibiotics," said Johnson. "But more than 70 percent of cases in men are asymptomatic, so many people are unaware they have it and do not seek treatment."
Johnson's next step will be using clinical samples from men with prostate cancer to verify whether her laboratory studies accurately reflect what happens during human infection.
