Comparison of miRNA-424 expression in tumours of different locations in the oral cavity. Paired samples of clinically normal tissue next to tumour and tumour samples from three different locations, gingiva, tongue and floor of the mouth were investigated for miRNA-424 expression. Results showed significantly different expression only between tongue tumours and clinically normal tongue controls (P=0.001). Neither gingiva nor floor of the mouth tumours showed any significant difference in miRNA-424 expression compared with their corresponding clinically normal tissue, ^NSP>0.05, **P<0.01.
