Fig. 1From: A pilot study to compare the detection of HPV-16 biomarkers in salivary oral rinses with tumour p16INK4a expression in head and neck squamous cell carcinoma patientsHPV-16 DNA in oral rinse associates with tumor p16INK4a status. a Detection of HPV-16 DNA in representative oral rinse samples of patients with p16INK4a-positive and p16INK4a-negative tumors using end-point PCR. (b) Analysis of HPV-16 DNA copy number in oral rinse of patients with p16INK4a-positive tumors using quantitative RT-PCR (ND = not detected). No HPV-16 DNA was detected in oral rinse of patients with p16INK4a-negative tumorsBack to article page
