Mean messenger RNA expression as measured by means of reverse transcription–polymerase chain reaction in primary tissue from 32 patients with head and neck squamous cell carcinoma compared with 7 normal upper aerodigestive mucosa samples from patients without cancer. Differences in tumor vs normal expression levels were significant as measured using a 2-tailed t test assuming unequal variance (P=.03). GAPDH indicates glyceraldehyde-3-phosphate dehydrogenase. Error bars represent SD.
