PIK3CA and non-small cell lung carcinoma: Using MassArray analysis, we confirmed the mutational profile of the following NSCLC cells: NCI-H661 (PTPN11- exon 3 mutated (N58), KRAS and PIK3CA WT), NCI-H157 (KRAS-mutated, PTPN11 and PIK3CA WT), NCI-H1703 (PTPN11, KRAS and PIK3CA WT) and Calu-3 (PTPN11, KRAS, and PIK3CA WT).
