To further validate the function of Serpinb9, we genetically ablated Serpinb9 in the murine Lewis Lung Carcinoma cells (LLC1), which were established from a C57Bl/6 mouse lung tumor, harbor the activating KrasG12D mutation and form immunogenic tumors when transplanted into syngeneic mice60. This evidence concerns the gene SERPINB9 and Carcinoma, Lewis Lung.
