John Hopkins researchers find over expression of a muscle protein in prostate cancer cells

UroToday – ‘Muscle’ Protein Drives Prostate Cancer: “Researchers at the Johns Hopkins Kimmel Cancer Center have for the first time implicated the muscle protein myosin VI in the development of prostate cancer and its spread.
In a series of lab studies with human prostate cancer cells, the Hopkins scientists were surprised to find overproduction of myosin VI in both prostate tumor cells and precancerous lesions. When the scientists genetically altered the cells to silence myosin VI, they discovered the cells were less able to invade in a test tube.

Discoveries like this will one day replace PSA as our screening tests for prostate cancer.
