Microdroplets may reduce colorectal tumor growth at potentially lower cost

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed microscopic peptide droplets that deliver large amounts of gene-silencing molecules into cancer and immune cells, reducing the growth of hard-to-treat colorectal tumors by about 67% in mice. The patent-pending system uses small interfering RNA, or siRNA, to disrupt the production of two proteins that cancer cells exploit to evade attacks by the immune system.
