RNA-sequence data of clinically never-metastatic primary small cell lung cancer cases and small cell lung cancer metastasis cases, FOXA2 knock-down and overexpression in cell lines

Small cell lung cancer (SCLC) is known for its high metastatic potential, with most patients demonstrating clinically evident metastases in multiple organs at diagnosis. The factors contributing to this exceptional metastatic capacity have not been defined. To bridge this gap, we compared gene expression in SCLC patient samples who never experienced metastasis or relapse throughout their clinical course, versus primary SCLC patient samples from more typical patients who had metastatic disease at diagnosis. This analysis identified FOXA2 as a transcription factor strongly associated with SCLC metastasis. We collected pathological slides from clinically never-metastatic primary small cell lung cancer cases and small cell lung cancer metastasis cases and extracted, processed for RNA-sequence
