Inhibition of protein synthesis by a toxic lectin from Viscum album L. (mistletoe).
نویسندگان
چکیده
1. The haemagglutinating and toxic lectin from Viscum album L. (mistletoe) inhibits protein synthesis in a lysate of rabbit reticulocytes, with an ID50 (concentration giving 50% inhibition) of 2.6 microgram/ml. This effect is enhanced (ID50 0.21 microgram/ml) if the lectin is reduced with 2-mercaptoethanol. 2. The lectin inhibits protein synthesis also in BL8L cells in culture. Inhibition occurs after a lag time of 3 h. The ID50 is 7 ng/ml, and increases after reduction of the lectin. 3. This and the gross lesions observed in rats poisoned with V. album lectin indicate this is a toxin very similar to ricin.

Mistletoe has been used as a drug against different diseases in po pular medicine for a long time, but the systematic research into anti-neoplastic activity of mistletoe extracts started only recently. Biological and anti-tumor activity of many protein fractions from mistletoe ex tract has been thouroughly investigated by V e s t e r et al. (1968 a, b), who determined optimal conditions for t...
متن کاملPaediatric medulloblastoma cells are susceptible to Viscum album (Mistletoe) preparations.
BACKGROUND Medulloblastoma constitute more than 20% of all paediatric brain tumours and are the most common malignant brain tumours in children. Adjuvant chemotherapy has seen a strong increase in the use of complementary medicine for cancer treatment. Evidence for cytotoxic and apoptotic effects of Viscum album (Mistletoe) in vitro is available, however, no data concerning paediatric tumours, ...
متن کاملIsolation and properties of three lectins from mistletoe (Viscum album L.).
Three lectins have been isolated from an extract of mistletoe (Viscum album) by affinity chromatography on partially hydrolysed Sepharose and human immunoglobulin- Sepharose. The lectins differ in molecular weight and sugar specificity (lectin I, mol.wt. 11500, D-galactose-specific; lectin II, mol.wt. 60000, both D-galactose- and N-acetyl-D-galactosamine-specific; lectin III, mol. wt. 50000, N-...

The extract of European mistletoe (Viscum album, L) has been used in adjuvant chemotherapy of cancer and mistletoe lectins are considered to be major active components. The present work was performed to investigate the effects of Korean mistletoe lectin (Viscum album L. coloratum agglutinin, VCA) on proliferation and apoptosis of human hepatoma cells as well as the underlying mechamisms for the...

An old goal of natural complementary medical therapy has been to aim at a long-term stimulation of natural resistance in order to restrain cancer progression or improve defective immunological conditions without toxic side effects. Mistletoe extracts were applied to a large number of cancer patients because of their modulatory effect on the natural immune system. By carefully removing lectins, ...
