  "summary": "Scientists from Nanyang Technological University in Singapore have developed microscopic peptide droplets that effectively reduce the growth of colorectal tumors by about 67% in mice. The innovative system uses small interfering RNA (siRNA) to disrupt the production of two proteins, PD-1 and PD-L1, which cancer cells exploit to evade immune attacks. When combined, the siRNA treatments suppressed tumor growth to a level comparable with existing checkpoint immunotherapies, which use monoclonal antibodies costing five to 10 times more to produce. The NTU researchers estimate the siRNA-based approach could potentially be less expensive to develop and scale up.",
