The present study was aimed to evaluate the protective effects of Hydroethanolic Murraya koenigii leaves extract (HEMKLE) against DMBA/TPA-induced angiogenesis, hepatotoxicity and renal toxicity during skin carcinogenesis in mice. For study, male LACA mice were divided into four groups: Group I (C), II (DMBA/TPA), III (HEMKLE), IV (HEMKLE+DMBA/TPA). 7, 12-dimethylbenz(a) anthracene (DMBA), 12-O...

Objective- Breast cancer is one of the most serious problems in oncology. Alkaloids pyrrolizidine are widely found in nature and exhibited versatile biological activities. The aim of the present study was to assess anti-tumor activity of methyl 1,3-dioxo-1,1',2',3,5',6',7',7a'-octahydrospiro[indene-2,3'-pyrrolizidine]-2'-carboxylate (6) on 7,12 dimethylbenz(a) anthracene (DMBA)-induced mammary ...

The formation of epidermal DNA adducts from 9-fluoro-7,12-dimethylbenz(a)anthracene (9-F-DMBA) was compared with 7,12-dimethylbenz(a)anthracene (DMBA) and 10-fluoro-7,12-dimethylbenz(a)anthracene (10-F-DMBA) in SENCAR mice. 9-F-DMBA is equipotent, whereas 10-F-DMBA is more potent than DMBA for skin tumor initiation in this mouse stock. The quantity of covalently bound DNA adducts was essentiall...

in this study,14 female sprague-dawley rats 55 days old were randomly divided into two control and experimental groups.2ml of 7,12-dimethylbenz{a} anthracene (DMBA) solution(20 mg of DMBA dissolved in 2 ml of corn oil) and 2 ml corn oil was eaten to each animal of test and control group respectively.tumor development was examined by milk line palpation once every week.during 3-5 months followin...

The role of dietary factors in inhibiting or delaying the development of non-melanoma skin cancer (NMSC) has been investigated for many years. Cardamom, which is a dietary phytoproduct, has been commonly used in cuisines for flavour and has numerous health benefits, such as improving digestion and stimulating metabolism and having antitumorigenic effects. We have investigated the efficacy of di...

In this study, the therapeutic effects of Pistacia terebinthus L. subsp. Palaestina (terebinth) and Rhus coriaria L (sumac) plants on DMBA-induced breast cancer in 66 female Sprague-Dawley rats were investigated through biochemical analysis. The divided into 6 groups as Control, DMBA (7.12-Dimethylbenzanthracene), PT (terebinth), RC (sumac), PT+DMBA RC+DMBA. was administered to 8-week-old via g...

Aryl hydrocarbon hydroxylase of mouse skin is inducible by benz(a)anthracene or 7,12-dimethylbenz(a)anthracene (DMBA) and is inhibited by 7,8-benzoflavone. 7,8-Benzo flavone inhibits the formation of covalently bound complexes of DMBA with DNA, RNA, and protein and also inhibits tumor formation caused either by a single application of DMBA, followed by croton oil treatment, or by the repeated a...

Studies examined the in vivo binding of radiolabeled 7,12-dimethylbenz(a)anthracene (DMBA) to hamster cheek pouch epithelial DNA. Adduct formation was studied as functions of [3H]DMBA dose and of the time after single [3H]DMBA applications in mineral oil. Total DMBA-DNA adduct formation was determined by DNA-bound 3H activity, and qualitative binding characteristics were further studied by high...

The effects of 1.5 GHz electromagnetic near fields of time division multiple access (TDMA) signal for the Personal Digital Cellular, Japanese cellular telephone standard (PDC) used for cellular phones, on mouse skin carcinogenesis initiated by 7,12-dimethylbenz[a]anthracene (DMBA) were examined. Ten-week-old ICR female mice were treated with a single application of DMBA on shaved dorsal skin by...
