BioMedicine
Background: Acetylation and trimethylation of histone H3 lysine 27 (H3K27ac and H3K27me3) generally activate and repress transcription, respectively. Concurrent activation of H3K27ac and H3K27me3 has been reported to correlate with poor prognosis in hepatocellular carcinoma. A high level of H3K27me3 has been shown to be associated with advanced oral squamous cell carcinoma (OSCC) tumour stage, but prognostic impact of H3K27ac level alone/or in combination with H3K27me3 in OSCC patients had not yet been reported. Material and Methods: In this study, immunohistochemistry using specific antibodies against H3K27ac and H3K27me3 was performed on a series of 72 OSCC samples to investigate the …
