Carcinogenesis
09/15/1991 - "
A radioactive compound tentatively identified as a TP-BPDE-I adduct could be recovered from epidermal homogenates following topical application of TP and BPDE-I. We used a standard two-stage initiation-promotion protocol to test the effects of these compounds on mouse skin carcinogenesis.
"
03/13/1998 - "
These results demonstrate that there are higher levels of 8-OHdG and BPDE-I-DNA adducts in tumor and tumor-adjacent tissues than in normal tissues and that these higher levels might be related to gastric tumorigenesis, although benzo[a]pyrene could be a minor contributing component in the environment.
"
12/01/1991 - "
The initiation of carcinogenesis by carcinogens such as 7r,8t-dihydroxy-9,10t-oxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE-I) is thought to involve the formation of DNA adducts.
"
05/01/1988 - "
The formation of DNA adducts by the ultimate carcinogen 7r,8t-dihydroxy-9t,10t-oxy-7,8,9,10-tetrahydrobenzo[alpha]pyrene (BPDE-I) has been implicated in the process of carcinogenesis.

Xeroderma Pigmentosum (Kaposi's Disease)
05/01/1994 - "
No threshold was observed in experiments with human fibroblasts deficient in excision repair (xeroderma pigmentosum group A); calculated D0 values were 1.2 pyrimidine dimers of 2.1 BPDE-I adducts.
"
06/01/1991 - "
Cellular capacity for postreplication repair (PRR) and sensitivity to transformation to anchorage independence (AI) were quantified in normal foreskin and xeroderma pigmentosum (XP) variant fibroblasts after treatment with UV or benzo(a)pyrene-diol-epoxide I (BPDE-I).
"
05/01/1990 - "
Postreplication repair (PRR) was quantified in normal human fibroblasts and in xeroderma pigmentosum (XP) variant fibroblasts after treatment with UV or benzo[a]pyrene diol epoxide-I (BPDE-I).

Neoplasms (Cancer)
07/01/2000 - "
It is concluded that measurement of BPDE-I-DNA adduct levels in coke plant workers is essential in determining cancer risk due to high exposure to PAHs, and in particular of B[a]P.
"
03/13/1998 - "
In smokers, BPDE-I-DNA adduct was slightly higher in tumor tissues (4.92 +/- 0.82 fmol/microg DNA) than in tumor-adjacent tissues (3.99 +/- 0.92 fmol/microg DNA).
"
03/13/1998 - "
In males, BPDE-I-DNA adduct was significantly higher in tumor tissues (4.25 +/- 0.42 fmol/microg DNA) than in normal tissues (2.83 +/- 0.59 fmol/microg DNA) (P < 0.05).
"
03/13/1998 - "
Higher levels of total BPDE-I-DNA adduct were observed in tumor (4.20 +/- 0.59 fmol/microg DNA) and tumor-adjacent (3.68 +/- 0.62 fmol/microg DNA) tissues than in normal stomach tissues (2.80 +/- 0.53 fmol/microg DNA) but were not significant.
"
03/13/1998 - "
These results demonstrate that there are higher levels of 8-OHdG and BPDE-I-DNA adducts in tumor and tumor-adjacent tissues than in normal tissues and that these higher levels might be related to gastric tumorigenesis, although benzo[a]pyrene could be a minor contributing component in the environment.

Hypersensitivity (Allergy)
05/01/1988 - "
In a line of Chinese hamster ovary (CHO) cells designated AT3-2 and in two derivative mutant lines, UVL-1 and UVL-10, originally selected for hypersensitivity to UV-irradiation, we have measured the formation of BPDE-I: DNA adducts and the production of biological damage.

Hepatocellular Carcinoma (Hepatoma)
05/15/1993 - "
Polycyclic aromatic hydrocarbons such as benzo(a)pyrene diol-epoxide (BPDE-I) cause hepatocellular carcinoma.
