| Abstract |
Alterations of the P53 gene and human papillomavirus (HPV) infection are associated with development of oral squamous cell carcinoma (OSCC). We aimed to identify mutation of P53 exon 8 codon 282 in OSCC and correlate these with HPV infection as well as histopathological grade of OSCC. Samples of known HPV infection status were studied including oral lesion cells, formalin-fixed paraffin embedded (FFPE) tissues from OSCC and exfoliated oral cells of matched age-sex controls. P53 exon 8 mutation was detected using the polymerase chain reaction (PCR). Mutation of codon 282 was identified by allele-specific oligonucleotide typing (ASO) using EvaGreen real-time PCR. The PCR products were analyzed by gel electrophoresis and melting curve analysis. Mutation of P53 exon 8 was seen in 81.7% and 69.6% of FFPE OSCC tissues and oral lesion cells, respectively. This was significantly higher than in controls (16.7%). Frequency of mutation did not differ between HPV-positive samples (62.5% and 81.8% in oral lesion cells and FFPE tissue samples, respectively) and HPV-negative samples (73.3% and 81.5% in oral lesion cells and FFPE tissue samples, respectively). This finding is similar to P53 codon 282 mutation that was found only in FFPE tissues (35.0%) and oral lesion cells (32.6%) from both HPV-positive and negative OSCC. Interestingly, frequency of mutation was higher in well-differentiated OSCC with HPV-infection (28.1%) than without HPV (14.8%). This result demonstrated a mutation hot spot in P53 associated with oral carcinogenesis and might be useful to guide chemotherapeutic modality for HPV-associated OSCC in northeast Thailand. |
