anthracene/breast neoplasms

Breast cancer is one of the most common cancers in women of developed and developing countries. The optimum management of which requires a multidisciplinary approach including the use of certain biochemical and molecular markers. The effect of propolis along with paclitaxel on 7,12 dimethyl

Reactive oxygen species (ROS) directly or indirectly involves in multistage process of carcinogenesis. Antioxidant activity of methanolic extract of Operculina turpethum stems (MEOT) on 7,12 dimethylbenz(a)anthracene (DMBA) induced breast cancer was investigated in female Sprague-Dawley rats.

Medroxyprogesterone acetate (MPA) is a synthetic progestin commonly administered to postmenopausal women for hormone replacement therapy and has been associated with increased risk of breast cancer. MPA has been shown to accelerate the development of mammary tumors in a

DMBA is a major class of potent genotoxic chemical carcinogen present in the environment and it may increase breast cancer risk. Flavonoids have been shown to have interesting biological activities in many experimental investigations. Hesperidin is one of the citrus flavonoid shown to be active

There is evidence that aspirin and other non-steroidal anti-inflammatory drugs may be protective agents against cancer in the gastrointestinal tract. These effects are particularly well documented for the colon and rectum. Some epidemiological and experimental studies have suggested that aspirin

Consumption of α-lactalbumin as dietary protein offers a beneficial effect on breast cancer development. Breast cancer was developed by gavage administration of single dose of dimethylbenz(a)anthracene (DMBA) in female rats, maintained on AIN-76A diet with either 20% casein or α-lactalbumin (a

Artemisinin, a compound isolated from the sweet wormwood Artemisia annua L., has previously been shown to have selective toxicity towards cancer cells in vitro. In the present experiment, we studied the potential of artemisinin to prevent breast cancer development in rats treated with a single oral

Objective: To determine the effect of electro-acupuncture (EA) treatment on serum levels of interferon-γ (IFN-γ) in rats with 7,12-dimethylbenz(α)anthracene (DMBA)-induced breast tumors. Methods: Twenty five female Wistar rats were divided randomly into 5 groups: normal group (N; neither

Objective: To explore the feasibility of 7, 12-dimethylbenz[a] anthracene (DMBA) induced tree shrew breast cancer model, and compare the effects of two administration modes by gavage and mammary gland injection. Methods: A total of 40 tree shrews were randomly divided into two groups

BACKGROUND The dimethylbenz(alpha)anthracene (DMBA) breast cancer model induced in the rat is used for the study of mammary carcinogenesis because it closely mimics human breast disease. OBJECTIVE To analyze the histopathologic features of mammary carcinomas induced in the DMBA experimental model,

The relationships between dietary fat concentration (10 or 40% of energy), fat source (corn oil or beef tallow) and estrogen (control, ovariectomy or ovariectomy with estrogen replacement) to 7,12-dimethylbenz(a)anthracene (DMBA)-induced breast carcinogenesis and survival in rats were studied in a 2

Breast cancer is the most common malignancy in women worldwide. Environmental factors such as xenobiotic exposure and lifestyle and nutrition play a key role in its etiology. This study was designed to evaluate the age-related changes in the expression of major xenobiotic-metabolizing enzymes (XMEs)

The incidence of breast cancer among women is high and increasing. This study investigated the inhibitory effect of an extract from bamboo Phyllostachys edulis on the development of 7,12-dimethylbenz[a]anthracene (DMBA)-induced breast cancer in female Sprague-Dawley rats. The rats were fed with

This study was to demonstrate by histological grading whether soy protein protects against dimethylbenz[a]anthracene (DMBA) -induced breast tumors in female rats. At 25 days of age, rats were fed diets containing either casein or soy protein. After 25 days on diets, a single dose of DMBA in sesame

Estradiol (E2) is well known as stimulator of the growth of 7,12-dimethylbenz(a)anthracene (DMBA)-induced mammary tumors. The effect of estrone (E1), however, has not been described in this model of human breast cancer. As E1 is the predominant estrogen precursor in postmenopausal women, we have
