Using polysaccharides against cancer
Background and objectives: Nowadays cancer is one of the most important concerns of the society. The adverse effects of common therapeutics and resistance of some cancerous cells to treatment have brought the necessity of new approaches towards the issue. Polysaccharides are a group of carbohydrates found in natural sources. In the present article, our goal was to show the posi...
متن کاملInteraction between acidic polysaccharides and proteins.
There was an ionic interaction between acidic polysaccharides (APS) and proteins at the pH range in which APS were negatively charged and proteins were positively charged, and in enzymes the interaction was detected as a change in the enzyme activity. At pH 4.7, acid phosphatase (pI, 5.4), alpha-glucosidase (pI, 5.7), and beta-glucosidase (pI, 7.3) were inhibited by APS to various extents. On t...
متن کاملImmunomodulatory activity of acidic polysaccharides isolated from Tanacetum vulgare L.
Tanacetum vulgare L. (Tansy) has been extensively used in folk medicine for treatment of a variety of medical disorders. In the present study, we isolated and purified four acidic polysaccharide fractions (designated T-I to T-IV) from Tansy florets by the sequential use of hot-water extraction, ethanol precipitation, ultra-filtration, anion-exchange, and size-exclusion chromatography. The avera...
متن کاملROS-Dependent Mitochondria Molecular Mechanisms Underlying Antitumor Activity of Pleurotus abalonus Acidic Polysaccharides in Human Breast Cancer MCF-7 Cells
BACKGROUND A greater reduction in cancer risk associated with mushroom diet rich in fungus polysaccharides is generally accepted. Meanwhile, edible Pleurotus abalonus as a member of Abalone mushroom family is a popular nutritional supplement that purportedly prevents cancer occurrence. However, these anecdotal claims are supported by limited studies describing tumor-inhibitory responses to the ...
متن کاملWidespread occurrence of a covalent linkage between xyloglucan and acidic polysaccharides in suspension-cultured angiosperm cells.
BACKGROUND AND AIMS Covalent linkages between xyloglucan and rhamnogalacturonan-I (RG-I) have been reported in the primary cell walls of cultured Rosa cells and may contribute to wall architecture. This study investigated whether this chemical feature is general to angiosperms or whether Rosa is unusual. * METHODS Xyloglucan was alkali-extracted from the walls of l-[1-3H]arabinose-fed suspens...
