Pathway analysis using the database for annotation, visualization, and integrated discovery (DAVID) demonstrated a significant number of genes transcriptionally responsive to the loss of MLL fusion expression to be involved in the KEGG focal adhesion pathway (hsa04510, p<0.0001) and the KEGG small cell lung cancer pathway (hsa05222, p = 0.008). This evidence concerns the gene KMT2A and small cell lung carcinoma.
