초록

Genomic imprinting is defined as parent-of-origin expression of specific genes and may play an important role in embryonal development of mammals. Loss of imprinting(LOI), biallelic expression of the imprinted genes, have been observed in a variety of human tumors and syndromes. H19, a paternally imprinted gene, is transcribed as an untranslated RNA that serves as a riboregulator. LOI of H19 is observed in a variety of human malignancies. In this study, LOI of H19 was examined in head and neck squamous cell carcinomas(HNSCCs). Four(28.6%) of the 14 HNSCCs and 8(28.6%) of the 28 inflammatory oral lesions were informative for imprinting analysis of H19. H19 was imprinted in all inflammatory oral lesions, however, 2(50%) of the 4 informative HNSCCs manifested LOI. These data suggest that LOI of the H19 may play a role in the oncogenesis of HNSCC.
