The fragile histidine triad (FHIT) tumor suppressor gene at 3p14.2 has abnormalities in several types of human cancers. To investigate the potential role of FHIT in cervical cancer, which exhibits frequent loss of heterozygosity of 3p, we have examined primary cervical cancer samples from 28 patients for alterations of the FHIT gene. Abnormal FHIT transcripts were detected using reverse transcription-polymerase chain reaction (PCR) and subsequently by sequencing. Of 28 primary cervical carcinomas analyzed, 12 tumors (43%) showed abnormal FHIT transcripts, including deletion, insertion and point mutation. Loss of a FHIT transcript was observed in 2 cases (7%). Allelic loss of the FHIT gene was detected in 16 of 27 informative cases (59%). Oncogenic human papillomavirus (HPV) type 16, 18, 33, 35, 58 and 59 were not only present but were expressed in 24 of 28 cases (85%) by consensus PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) analysis for the HPV E6 and E7 genes. Our data indicate that alteration of the FHIT gene is an important genetic event associated with cervical cancer and oncogenic

UI MeSH Term Description Entries
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009363 Neoplasm Proteins Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm. Proteins, Neoplasm
D011506 Proteins Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein. Gene Products, Protein,Gene Proteins,Protein,Protein Gene Products,Proteins, Gene
D012150 Polymorphism, Restriction Fragment Length Variation occurring within a species in the presence or length of DNA fragment generated by a specific endonuclease at a specific site in the genome. Such variations are generated by mutations that create or abolish recognition sites for these enzymes or change the length of the fragment. RFLP,Restriction Fragment Length Polymorphism,RFLPs,Restriction Fragment Length Polymorphisms
D002294 Carcinoma, Squamous Cell A carcinoma derived from stratified SQUAMOUS EPITHELIAL CELLS. It may also occur in sites where glandular or columnar epithelium is normally present.
