Could blocking or deleting a protein help prevent common oral cancers?
Source: www.eurekalert.org Author: Boston University The most common head and neck cancer—oral squamous cell carcinoma—often starts off, as many other cancers do, quite innocently. Perhaps as a little white patch in the mouth or a small red bump on the gums. Easy to ignore, to downplay. But then something changes, and the little blotch becomes more ominous, starts growing, burrowing into connective tissue. Patients who are lucky enough to see a dentist before things take a nasty turn have a shot at being able to prevent the lesions from turning cancerous—or can at least make sure treatment starts when it’s most effective. But for those who aren’t that lucky, the outlook can be bleak: the five-year survival rate of oral squamous cell carcinoma (OSCC) is around 66 percent. More than 10,000 Americans die of oral cancer every year; smokers and drinkers are hardest hit. Now, researchers at Boston University’s Henry M. Goldman School of Dental Medicine have found that dialing back—or even genetically deleting—a protein that seems to spur the cancer’s growth might help limit a tumor’s development and spread. They say their findings make the protein, an enzyme called lysine-specific demethylase 1, a potential “druggable target”—something that doctors could aim chemo and immuno-oncology therapies at to take down a tumor. The study was published in February in Molecular Cancer Research. Given that at least one-third of Americans don’t visit a dentist regularly, according to the Centers for Disease Control and Prevention, the discovery could be a future lifesaver for [...]
