In vivo reactivation of DNases in implanted human prostate tumors after administration of a vitamin C/K(3) combination.

Human prostate cancer cells (DU145) implanted into nude mice are deficient in DNase activity. After administration of a vitamin C/vitamin K(3) combination, both alkaline DNase (DNase I) and acid DNase (DNase II) activities were detected in cryosections with a histochemical lead nitrate technique. Alkaline DNase activity appeared 1 hr after vitamin… CONTINUE READING
