The purpose of our study was to assess the prevalence and prognostic significance of HPV infection as well as K-ras codon 12 point mutations in lung cancer. Patients diagnosed with lung carcinoma between 1988 and 1992 (N=99) were selected. HPV detection and typing was performed by PCR from paraffin-embedded tissues, while mutations in codon 12 of K-ras gene(More)
The purpose of this study was to assess the extent of involvement of the ras oncogene activation by point mutations in endometrial carcinoma in the Greek population. The PCR technique was employed, followed by RFLP analysis to identify the point mutations in codon 12 of the K-ras, H-ras and N-ras genes. K-ras gene point mutations were detected in 8 of the(More)
Clinical observations and epidemiological studies on genital cancer have revealed an association with sexual behavior, thus motivating research into sexually transmitted agents which may be responsible for the neoplasia. In this study, we used the PCR technique to examine the presence of CMV, HSV and EBV viruses in 187 cases of human genital lesions and(More)
We used the PCR technique to detect the Epstein-Barr virus (EBV) and human papillomavirus (HPV) DNA in paraffin-embedded tissues from Greek patients with nasopharyngeal carcinoma (NPC). The oligonucleotide primers used for the detection of EBV amplify a 375-bp long sequence from the EcoRI B fragment of the viral genome, whereas for HPV the primers amplify a(More)
Compatible with the epidemiology and natural history of cervical cancer and with experimental findings that HPV-immortalized nontumorigenic cells are similar to cervical carcinoma cells, in terms of the quantity and type of viral RNA expressed, it is believed that additional cellular genetic events are necessary for tumorigenic conversion. In the current(More)
Several lines of evidence suggest that mutation events may be involved in the development of atherosclerosis. The aim of the present investigation was to perform an allelotype analysis in 30 atherosclerotic lesions in order to reveal any deletions involved in the development of the disease. Eighteen chromosomal arms were tested by one microsatellite marker(More)
OBJECTIVE To investigate the role of human parvovirus B19 (Parvo B19), cytomegalovirus (CMV) and human papilloma virus (HPV) viruses in the aetiopathogenesis of spontaneous abortions. STUDY DESIGN Abortion material from 102 cases of women with spontaneous abortions were analysed for the presence of Parvo B19, CMV and HPV DNA using the polymerase chain(More)
The aetiopathology of atherosclerosis remains obscure. Although histologically the accumulation of lipids and the proliferation of the smooth muscle cells represents the main feature of the disease, little is known as regards the molecular alterations associated with the atherosclerotic lesions. In the present study we investigated whether an elevated(More)
A combined reverse transcription-polymerase chain reaction (RT-PCR) method was employed for the detection of hepatitis C virus (HCV) RNA in serum from patients with chronic active hepatitis, with primers corresponding to the 5' non-coding region. The diagnosis was based on serological and biochemical methods and on liver biopsy. HCV-RNA was detected in 27(More)
The levels of expression and the incidence of codon 12 point mutations of the ras family genes were studied in 18 cases of leukemia, seven with acute myeloblastic leukemia (AML), three with acute lymphoblastic leukemia (ALL), four cases with chronic myelogenic leukemia (CML) and four cases with chronic lymphocytic leukemia (CLL). Elevated expression of the(More)
