Overexpression of hnRNP K has been shown in many human tumours too, including lung cancer (Pino et al, 2003), esophageal cancer (Hatakeyama et al, 2006), oral squamous cell carcinoma (Roychoudhury and Chaudhuri, 2007), colorectal cancer (Carpenter et al, 2006b) and nasopharyngeal carcinoma (Chen et al, 2008). This evidence concerns the gene HNRNPK and neoplasm.
