LBX1 and head and neck squamous cell carcinoma: Data mining of our published gene expression profile of normal, premalignant and HNSCC cells (http://bioinformatics.picr.man.ac.uk/vice/PublicProjects.vice?pager.offset=15) to identify deregulated pathways [3] has identified a number of consistently up-regulated transcription factors in HNSCC, including several Homeobox (HOX) genes (see Hunter et al, Supplementary data S3 and S4).
