diallyl sulfide/유방암

Diallyl sulfide (DAS) is a component of garlic and prevents cancer in several animal models in various organs. The chemopreventive effects of DAS are attributed to modulation of enzymes to alter the bioactivation of xenobiotics. Diethylstilbestrol (DES) is a synthetic estrogen that causes breast

Previously, it has been demonstrated that microsomal, mitochondrial and nuclear enzymes isolated from the liver of male Sprague-Dawley rats catalyzed the oxidation of diethylstilbestrol (DES) to DES quinone. In the present study we have shown that diallyl sulfide (DAS) inhibits the oxidation of DES

Diethylstilbestrol (DES) is metabolized to reactive intermediates that produce DNA adducts and ultimately cancer. Diallyl sulfide (DAS) has been shown to inhibit the metabolism of several procarcinogens. The ability of DES to produce DNA adducts in microsomal, mitochondrial, and nuclear in vitro

Diethylstilbestrol (DES) causes DNA adducts resulting in breast cancer, whereas diallyl sulfide (DAS) inhibits cancer formation. We hypothesize that DAS induces the expression of nucleotide excision repair genes. To test this hypothesis, female ACI rats were treated for 4 days with corn oil, DES,

Intratumoral hypoxia promotes the distant metastasis of cancer subclones. The clinical expression level of hypoxia-inducible factor-1α (HIF-1α) reflects the prognosis of a variety of cancers, especially breast cancer. Histone deacetylase (HDAC) inhibitors can target HIF-1α protein due to von

Diethylstilbestrol (DES) induces mammary tumors in female ACI rats and is associated with an increased risk of developing breast cancer in humans. Diallyl sulfide (DAS) has been shown to prevent cancer in animals. Previously, we have shown that DAS inhibits the production of DES induced DNA adducts

Heterocyclic amines (HCAs) are formed when meat products such as beef, chicken, pork and fish are cooked at high temperatures. The most abundant HCA found in the human diet is 2-amino-1-methyl-6-phenylimidazo[4,5-b] pyridine (PhIP). PhIP causes mammary carcinomas in female rats and mice, and is

2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) is associated with mammary carcinomas in animals and humans. PhIP is metabolized by CYP 1A1/1A2 and cytochrome b5 reductase, producing free radicals causing DNA strand breaks. Diallyl sulfide (DAS) prevents cancer in animals. We hypothesized

Breast cancer is the second leading cause of cancer deaths in women in the United States. Diethylstilbestrol (DES) is a synthetic estrogen that has been shown to cause cancer in animals and humans, altering cell viability as well as inducing DNA damage. Diallyl sulfide (DAS) is a garlic

Multiple lines of evidence support an inverse association between consumption of garlic and the risk of cancer. Chemopreventive effects of garlic have been attributed to its oil-soluble sulfur ingredients, such as diallyl sulfide (DAS), diallyl disulfide (DADS), and diallyl trisulfide (DATS), but

Diallyl disulfide caused growth inhibition and differentiation of DS19 mouse erythroleukemic cells as judged by hemoglobin synthesis and induction of acetylcholinesterase activity. There was a 50% inhibition of cell division at about 0.25 mM diallyl disulfide which was much more effective than
