In an extension of our earlier studies, we examined the inhibitory effects of N-acetyl-S-(N-2-phenethylthiocarbamoyl)-l-cysteine (PEITC-NAC), myo-inositol (MI) and indole-3-carbinol (I3C) or 3,3'-diindolylmethane (DIM), alone and in combination, on 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone
Although noticeable scientific and technological progress, cancer remains one of the deadliest diseases worldwide and advancements in diagnosis, targeting and treating cancer cells are an urgency. In this study, we designed and synthesized novel amino acid and polypeptide modified polysaccharide
Photothermal therapy (PTT) can take advantage of the photothermal effects of photothermal agents to acquire the energy from laser irradiation and convert it into heat. This can intensively elevate the temperature of the surrounding environment to directly destroy the cancer cells. It is expected
The chemopreventive efficacy of N-acetyl-L-cysteine (NAC), anethole trithione, miconazole and phenethylisothiocyanate (PEITC), each of which would be expected to alter carcinogen metabolism, was examined in the dimethylbenzanthracene (DMBA) mammary carcinogenesis model. In this protocol, animals
The protective effect of N-acetyl-L-cysteine (NAC) and ascorbic acid on mutagen-induced chromosomal breakage was determined using human lymphoblastoid cell lines as well as freshly cultured lymphocytes from patients with head and neck malignancies and healthy control subjects. Mutagen sensitivity
We designed a novel short-term bitransgenic model to better characterize the effects of benzo(a)pyrene (BP) exposure on multi-organ carcinogenesis and to evaluate the effects of a well-recognized antioxidant, N-acetyl-L-cysteine (NAC), on neoplasia. We selected the p53 heterozygous Tg.AC (v-Ha-ras)
Garlic and its water-soluble allyl sulfur-containing compound, S-Allyl-L-cysteine Sulfoxide (ACSO), have shown antioxidant and anti-inflammatory activities, inhibiting the development of atherosclerosis. However, little is known about the mechanism(s) underlying the therapeutic effect of ACSO in
Castrate-resistant prostate cancer remains a major clinical challenge. Due to the toxicity profile of taxane-based chemotherapy and treatment failure in some patients, novel agents with improved efficacy to side effect profiles are urgently needed. Eg5, a member of the kinesin-5 family, controls the
Colorectal cancer is one among the most common cancers in the world and a major cause of cancer related deaths. Similar to other cancers, colorectal carcinogenesis is often associated with over expression of genes related to cell growth and proliferation, especially Epidermal Growth Factor Receptor
Allylmercapto glutathione S-conjugate, S-allylmercapto-L-cysteine (SAMC), which is biotransformed from allyl sulfides and from naturally occurring water-soluble garlic derivatives, has been known to inhibit tumorigenesis. We found that SAMC was able to induce apoptosis in gastric cancer cells in
Epidemiological and experimental carcinogenesis studies provide evidence that certain components of garlic have anti-cancer activity. Although the biotransformed garlic derivative S-allylmercapto-L-cysteine (SAMC) has been reported to show an inhibitory effect on tumorigenesis, the mechanisms are
Pancreatic ductal adenocarcinoma (PDA) remains a devastating disease worldwide. Although significant improvement has been made in understanding its pathophysiology, only small portion of patients with PDA are likely to benefit from curative surgery and current chemotherapy. Thus, there is an urgent
The effect of N-acetyl-L-cysteine on the cytotoxicity of tumor necrosis factor-alpha was investigated in cultured bovine pulmonary artery endothelial cells and L929 mouse tumor cells. In endothelial cells, a 72-h incubation with tumor necrosis factor-alpha (100 ng/ml) reduced the number of viable
The synthesis and characterization of the organotin compounds [(n-C(4)H(9))(2)Sn(cys)] (1), [(C(6)H(5))(2)Sn(cys)] (2), [(C(6)H(5))(3)Sn(Hcys).(H(2)o)] (3), {[(CH(3))(2)Sn(Kcys)(2)].2(H(2)0)} (4), {[(n-C(4)H(9))(2)Sn(Kcys)(2)].2(H(2)0)} (5) and {[(C(6)H(5))(2)Sn(Kcys)(2)].2(H(2)0)} (6) (where
To examine the anticancer effects of S-allyl-L-cysteine (SAC) in human bladder cancer cells and to identify possible molecular mechanisms, bladder cancer cell lines (HTB5, HTB9, JON, UMUC14, T24, and cisplatin resistant-T24R2) were incubated with SAC, and cell proliferation was measured using the
