The present study designed to investigate the protective effects of [6]-shogaol on 7,12-Dimethylbenz (a)anthracene (DMBA) induced buccal pouch carcinogenesis in male golden Syrian hamsters. Oral squamous cell carcinoma was developed in left buccal pouch of hamster by painting with 0.5% of DMBA, three times in a week. We observed an altered status of apoptotic associated gene expression (P53, bc...

Abstract: The aim of the present study was directed to investigate therapeutic efficacy intraperitoneally injected curcumin as anticarcinogenic treatment modality on 7,12-dimethylbenz[a]anthracene (DMBA) induced hamster buccal pouch(s) (HBP(s)) carcinoma. Subjects and methods: Thirty Syrian male hamsters, five weeks old, weighing 90-130g were divided into three group(s) (G(s)): A, B, C. G-A (ne...

Background: Cancer is one of leading cause death number 2 in the world,or six deaths 2018. The incidance breast cancer as much 11,6% and are 6,6% Medical plant be expacted has potential an anticancer with minimal side effects when used at correct dosage, timing it properly.
 Objectives: To determine effect garlic extract on histopathological picture female Sprague-Dawley rats induced DMBA....

As reações do ciclopaladado catiônico [Pd(N,C-dmba)(MeCN) 2 ](NO 3 ) (1) (dmba = N,Ndimetilbenzilamina), como os pré-ligantes 3,5-dimetilpirazol (Hdmpz); 2-quinolinatiol (qnSH) e 1,1’-bis(difenilfosfina)ferroceno (dppf) levaram à formação dos compostos, respectivamente, [Pd(N,C-dmba)(Hdmpz)(ONO 2 )]0.5CH 2 Cl 2 (2), [Pd(N,C-dmba)(qnSH)(ONO 2 )] 0.5CH 2 Cl 2 (3) e [Pd(N,C-dmba)(dppf)](NO 3 ) (4)...

Large doses of 7,12-dimethylbenz[a]anthracene (7,12-DMBA) caused the death of rats within 1 day. A small amount of any of 5 polynuclear aromatic hydrocarbons or of an aromatic amine given before the highly toxic dose of 7,12-DMBA resulted in survival for more than 2 months and the specific atrophy of testis which follows 7,12-DMBA was largely prevented. Among the protective aromatics is 7,12-DM...

PURPOSE The leaves of Gynura procumbens (Lour.) Merr. has been traditionally used as anticancer. Ethanolic extract of G. procumbens leaves (EGP) showed cytotoxic activity and anticancer activity in animal cancer model. This study was conducted to observe antiproliferative effect using male rat's liver cells induced by 7,12-dimethylbenz(a)antracene (DMBA). METHODS Forty days old Sprague Dawley...

TG.AC transgenic mice harbor a v-Ha-ras transgene and retain two normal c-Ha-ras alÃ-elesand are susceptible to skin tumor formation by 12-O-tetradecanoylphorbol-13-acetate (TPA). To determine whether nor mal c-Ha-ras antagonizes the oncogenic potential of the v-Ha-ras transgene and/or whether additional non-Ha-ra.v 7,12-dimethylhenz(a (anthra cene (DMBA) initiation target genes exist in mouse ...

The polycyclic aromatic hydrocarbon 7,12-dimethylbenz[a]anthracene (DMBA) is a potent carcinogen that produces immunotoxic effects in bone marrow. Here, we show that bone marrow stromal cells metabolize DMBA to such products as 3,4-dihydrodiol, the precursor to the most mutagenic DMBA metabolite. The BMS2 bone marrow stromal cell line constitutively expressed higher levels of CYP1B1 protein and...

The purpose of our study was to determine the effect of the combined action of phytochemicals on the early stages of skin tumorigenesis, i.e. initiation and promotion. We tested calcium D-glucarate (CG) given in the diet, while resveratrol (RES) and ursolic acid (UA) were applied topically. The 7,12-dimethylbenz[a]anthracene (DMBA)-initiated, 12-O-tetradecanoylphorbol-13-acetate (TPA)-promoted ...
