PTK2 and cancer: Moreover, we recently revealed that non-thermal atmospheric pressure plasma (NTP) can inhibit the invasive character of cancer cells by decreasing matrix metalloproteinase (MMP)-2/-9 and urokinase-type plasminogen activator (uPA) activities and rearranging the cytoskeleton (related with FAK/Src signals3), as well as inducing apoptosis and DNA damage, triggering sub-G1 arrest in cancer cells4, 5.
