Human papillomavirus (HPV) DNA has been detected in the great majority of cancers of the uterine cervix and anus, whereas the association of HPV DNA with cancer at other anogenital sites has produced less consistent results. This study was designed to compare HPV exposure among anogenital cancer cases and matched controls. Cases (1782) of anogenital cancer diagnosed in the Seattle area from 1978 to 1998 were identified and interviewed. Their responses were compared with those of 2383 age- and sex-matched controls. Blood was drawn at interview from both cases and controls and tested for antibodies to HPV-16 and HPV-18. Tissue blocks were tested for HPV DNA for 649 cases. Serum antibodies to HPV-16 were associated with in situ and invasive cancer at all sites among men and women with the exception of in situ penile cancer. Anti-HPV-18 antibodies were associated with cancers at all sites among women. The increased risk of cancer associated with HPV-16 seropositivity ranged from odds ratio = 1.8 (95% confidence interval, 1.4-2.5) for adenocarcinoma of the cervix to odds ratio = 5.9 (95% confidence interval, 3.4-10.3) for anal cancer in men. Associations between seroprevalence and cancers were stronger when analyses were restricted to HPV-16- or HPV-18 DNA-positive cases. HPV DNA was detected in >80% of cancers from all sites tested. HPV-16 DNA was the type most frequently detected at all sites (range, 40.9-82.2%). HPV-18 DNA was detected in 44.7% of adenocarcinomas of the cervix but detected much less often (2.6-18.1%) at other sites. These findings support an important role for HPV infection in anogenital cancer at all sites. Differences in the proportion of seropositives among HPV-16 DNA-positive cases by site suggest either that the immune response varies by site or that cancer development may lead to changes in antibody responses in a site-specific fashion.

Monoclonal antibody (MAb) 1C5 reacts with 87% of uterine cervical adenocarcinoma and bovine beta -casein, but not with squamous cell carcinoma. To clarify the characteristics of the antigen (beta-casein-like protein; BCLP) recognized by MAb 1C5, molecular cloning was performed using 5' rapid amplification of the cDNA ends (5' RACE) and the oligo-capping method. The protein predicted from the cDNA consisting of 937 nucleotides comprises 222 amino acids. The BCLP gene and deduced amino acid sequences were novel and showed no similarity to known cancer-associated genes in the database. Northern blot analysis showed that a 1.1 kb transcript was ubiquitously expressed in cancer cell lines and was predominantly expressed in uterine cervical adenocarcinoma. To clarify the function of BCLP, BCLP cDNA was transfected into L929 cells, resulting in a significant increase in cell area, a downregulation of cell growth rate and a decrease in cell attachment. We conclude that BCLP might be associated with cell morphology and a regulation of growth pattern of tumor.

Forty-three norditerpenoid alkaloids isolated from Aconitum, Delphinium and Consolida species have been evaluated for their cytotoxic effects on the tumor cell lines CT26 (murine colon adenocarcinoma), SW480 (human colon adenocarcinoma), HeLa (human cervical adenocarcinoma), SkMel25 (human melanoma) and SkMel28 (human malignant melanoma) with several multidrug resistance mechanisms and the non-tumor cell line CHO (Chinese hamster ovary cells). Neoline (5), 8-O-methylcolumbianine (6), 1,14-diacetylcardiopetaline (9), 18-O-demethylpubescenine (13), 14-deacetylpubescenine (14), pubescenine (15), 14-deacetylajadine (25), lycoctonine (26), browniine (28), delphatine (29), dehydrotakaosamine (34), and ajadelphinine (37) exhibited selective cytotoxicity to cancerous versus non-cancerous cells. Some of these compounds had an irreversible effect on SW480 (5, 15, 25, 26, and 34), HeLa (15, 34, and 37) and SkMel25 (15 and 34) cell lines. In order to gain insights into the mechanism of irreversible cytotoxic action of these compounds we compared the cell viability by means of the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) and the acid phosphatase (AP) methods. Our results suggest that the effects of these compounds could be related to the inhibition of ATP production.

Nine halogenated monoterpenes isolated from the red alga Plocamium cartilagineum have been evaluated for their cytotoxic effects on the tumor cell lines CT26 (murine colon adenocarcinoma), SW480 (human colon adenocarcinoma), HeLa (human cervical adenocarcinoma) and SkMel28 (human malignant melanoma) with several multidrug resistance mechanisms and the mammalian non-tumor cell line CHO (Chinese hamster ovary cells). The activities of these compounds were compared with those of the insecticide gamma-hexachlorocyclohexane (lindane) due to chemical structure similarities. Compounds 1, 2, 3, and 5 exhibited selective cytotoxicity against colon and cervical adenocarcinoma cells. Interestingly, the effect of compound 3 was specific and irreversible to human colon adenocarcinoma SW480 cells, which overexpress the transmembrane P-glycoprotein often related to chemoresistance. None of the anti-tumor doses of these compounds was cytotoxic against CHO cells. Furthermore, analysis of cellular extracts after incubation with the test compounds and rotenone (positive uptake control) demonstrated the intracellular accumulation of 1, 2, 3, and 5.
