danthron/neoplasms

BACKGROUND Heme oxygenase (HO) catalyzes NADPH-dependent degradation of heme to liberate iron, carbon monoxide and biliverdin. The interaction between HO and cytochrome P450 reductase (CPR), an electron donor, is essential for HO activity. HO-1 is a stress-inducible isoform whereas HO-2 is

In contrast to the steady increase in survival observed for most cancer types, advances have been slow for pancreatic cancers. Current chemotherapy has limited benefits for patients with pancreatic cancer. Therefore, there is an urgent need for effective pancreatic cancer treatment strategies. At

In this study, we investigated the effect of danthron on the cell migration and invasion of human brain glioblastoma multiforme GBM 8401 cells in vitro. The changes of migration and invasion of GBM 8401 cells after treatment with danthron were detected by cell migration assay and cell invasion

Danthron (1,8-dihydroxyanthraquinone), is one of component from Rheum palmatum L. (Polygonaceae), has been shown several biological activities but did not show to induce apoptosis in human brain tumor cells. The aim of this study is to investigate the mechanisms by danthron for the induction of

The tumor-promoting activity of the anthraquinone laxative danthron was studied by giving 3 groups of male rats a single subcutaneous injection of the colon tumor-inducing agent 1,2-dimethylhydrazine (DMH). After 1 week, the animals were fed diets containing 0, 600 or 2400 ppm of danthron for 26

The anticancer potential of anthraquinones danthron and quinizarin on highly metastatic B16-F10 melanoma murine cells was investigated. Several parameters related to cell proliferation and differentiation, i.e. cell number, intracellular content of polyamines, transglutaminase (EC 2.3.2.13) activity

1,8-Dihydroxyanthraquinones are under debate as plant-derived carcinogens that are found in laxatives, food colors, and possibly vegetables. Published genotoxicity data are controversial, and so three of them (emodin, danthron and aloe-emodin) were tested in a number of in vitro assay systems. All

Centchroman (CC), a non-steroidal oral contraceptive and a candidate drug for breast cancer, has been reported to exhibit partial to complete remission of lesions in 40.5% of breast cancer patients. The potent anti-oestrogenic activity, negligible side-effects and anti-breast cancer activity of CC

Anthranoid laxatives, belonging to the anthraquinones as do anthracyclines, possibly increase colorectal cancer risk. Anthracyclines interfere with topoisomerase II, intercalate DNA and are substrates for P-glycoprotein and multidrug resistance-associated protein 1. P-glycoprotein and multidrug

Traditional Chinese Medicine (TCM) is widely used in clinical research due to its low toxicity, low number of side effects, and low cost. Many components of common fruits and vegetables play well-documented roles as chemopreventive or chemotherapeutic agents that suppress tumorigenesis.

Laxatives are among the most commonly used drugs or additives. Most are quite safe when used judiciously, intermittently when possible, and in the absence of contraindications. Bulking agents and nonabsorbable compounds such as lactulose can cause bloating but have very few serious adverse effects
