Ultraviolet Light - Major Risk Factor in Skin Cancer
Research by Dr. Wendy Bollag, corresponding author of the study shows that UV's ill effects are cumulative and dose dependent: more UV exposure equals more activity by the enzyme protein kinase D. That's another wakeup call about excess sun exposure particularly as we age, Bollag said, and an indicator that protein kinase D inhibitors, already under development for other cancers, may also work for skin cancer.
Skin cells normally make protein kinase D to help regulate growth needed to replace cells that are constantly sloughing off.
"The skin has to continually divide to replace cells that get lost to the environment," Bollag said.
Even something as benign as wearing clothes prompts skin cell loss and the constant demand for new ones.
"So, protein kinase D is good under normal conditions, when it's regulated appropriately. But what can happen is it starts misbehaving," Bollag said.
Its increased activity enables skin cells to survive the constant onslaught of UV radiation, which can be good or bad.
"If the damage caused by UV is relatively minor, so the cell can repair it, that's good. You wouldn't want to walk across the street, your skin gets hit by UV, all the cells die and your skin sloughs off," Bollag said.
