A wide variety of plant-derived compounds, including the polyphenolic flavonoids, is present in the human diet or is consumed for medicinal reasons. Epidemiological and animal studies tend to suggest a protective effect of flavonoids against cardiovascular diseases and some types of cancer. Although flavonoids have been studied for about 50 years, the cellular mechanisms involved in their biolo...
Objectives: To ascertain the protective effect of p53 tumor protein by monitoring its levels in comparison with antioxidant enzymes, against any type cancer that can be caused chronic exposure traffic policemen to air pollutants.
 Methods: This study comprises 140 participants, who have been divided into two groups (Traffic police and Office police). PAHs were analyzed for each participant...
Benzo(a)pyrene (BaP) is highly carcinogenic in rats but is without effect in rabbits when administered s.c. The possibility that BaP-DNA adducts could be responsible for this species difference was investigated by comparing BaP-deoxyribonucleoside adducts formed in dermal fibroblast cultures from Wistar rats and New Zealand rabbits. Treatment with [G-3H]BaP (1.2 microM) for 6, 24, and 48 h prod...
Probiotic microorganisms such as lactic acid bacteria (LAB) exert a number of strain-specific health-promoting activities attributed to their immunomodulatory, anti-inflammatory and anti-carcinogenic properties. Despite recent attention, our understanding of the biological processes involved in the beneficial effects of LAB strains is still limited. To this end, the present study investigated t...
Although it is well known that ultraviolet light exerts a potent carcinogenic effect upon the skin, it is not known whether this effect is exerted directly upon a chromosome or a gene, or whether it is exerted indirectly through the formation of a carcinogenic compound. Indirect evidence that ultraviolet light does not exert its carcinogenic effect through the formation of a chemical resembling...
To investigate the anti-carcinogenic effects of Atorvastatin (Atorva) on a rat bladder carcinogenesis model with N-butyl-N-(4-hydroxibutil)nitrosamine (BBN), four male Wistar rat groups were studied: (1) CONTROL: vehicle; (2) Atorva: 3 mg/kg bw/day; (3) Carcinogen: BBN (0.05%); (4) Preventive Atorva: 3 mg/kg bw/day Atorva + BBN. A two phase protocol was used, in which the drug and the carcinoge...
