Three NRAS‐mutant (NRASMUT; Lewis lung carcinoma, LLC, and AE17 malignant pleural mesothelioma of C57BL/6 mice carried NrasQ61H; human SKMEL2 skin melanoma carried NRASQ61R) and eight NRAS‐wild‐type (NRASWT; MC38 colon adenocarcinoma, B16F10 skin melanoma, and PANO2 pancreatic adenocarcinoma of C57BL/6 mice; CT26 colon adenocarcinoma and AB2 malignant pleural mesothelioma of BALB/c mice; as well as human A549 and HCC‐827 lung adenocarcinomas and MDA‐MB‐231 breast carcinoma) tumor cell lines were identified (Fig EV1A). This evidence concerns the gene NRAS and breast carcinoma.
