They both serve as nutritional reserves particularly in seeds and structural elements i. Reasonable efforts have been made to publish reliable data and information, but the author and the publisher cannot assume responsibility for the validity of all materials or for the consequences of their use. Some plants containing phenols with anticancer properties are indicated in Table 2. Proteins may be soluble in water and dilute salt solutions albumins , in dilute salt solutions globulins , in very dilute acids and bases glutelins or in ethanolic solutions prolamines. American mandrake Podophyllum hexandrum : Cell suspensions of P. Considerable efforts have been made by public organizations and private companies to expedite the processes of drug discovery and development, by expanding on promising results from preliminary in vitro screening tests.

Proto-oncogenes encourage such growth, whereas tumor suppressor genes inhibit it. Furthermore, inert additives may also be included. Cancers with five-year survival rates at all stages higher than 80% 1 Prostate cancer is associated with increasing age, obesity and race. They store water, salts, various organic metabolites, toxic substances or waste products and water-soluble pigments. Once considered a mysterious disease, cancer has been eventually revealed to investigators Trichopoulos and Hunter, 1996. Secondary metabolites Secondary metabolites are compounds belonging to extremely varied chemical groups, such as organic acids, aromatic compounds, terpenoids, steroids, flavonoids, alkaloids, carbonyles, etc.

The text closes with a discussion of algal extracts and isolated metabolites with anticancer activity, a summary of published research for each species, and chemical structures of the most important compounds. Coumarins are especially common in grasses, orchids, citrus fruits and legumes. In an ideal situation, cancer cells would constitute a target of the patient host immune system. Danish researchers tested the treatment on 17 women with advanced breast cancer that had not responded to other treatments. Buy with confidence, excellent customer service!. Accumulation of podophyllotoxin has been increased twelve-fold after precursor feeding with coniferin, a glucosylated intermediate of the phenyl- propanoid pathway Smollny et al. For example, the cell membrane permits the controlled entry and exit of compounds into and out of the cell while preventing excessive gain or loss of water and metabolic products.

These enzymes phosphorylate certain substrates that have been implicated in regulating cellular proliferation, usually via phosphorylation of elongation factor 2. Other compounds include trace elements selenium, zinc, lithium , hemocyanin, propionibacteria. As an example, human epithelial cells cultured in vitro are commonly capable of sustaining division for no more than 50 times the so-called Hayflick number Hayflick and Hayflick, 1961. Immunomodulatory proper- ties have been also ascribed to this group of secondary metabolites. Normal cells have a limited life span. A summary of published research for each species and the chemical structures of the most important compounds are provided as background information for the expert reader. Evolutionary aspects of the anticancer properties of plants are presented and a separate chapter is devoted on the application of biotechnology in this field.

Peptides are small proteins, amino acid oligomers with a molecular weight below 6000. Certain neoplastic animal cell lines have been repeatedly used for this purpose. The majority of flavonoids contain a pyran ring linking the three-carbon chain with one of the benzene rings. Ironically, unidentified extracts are usually more potent against various types of cancer than single, well-studied molecules. Promising candidates for the future: plant species with a laboratory-proven potential 72 3. Despite the vast number of possible polysaccharides, only few of the structural possibilities actually exist. Chemotherapy is the most rapidly developing field of cancer treatment, with new drugs being constantly tested and screened.

G Terpenes and steroids are produced from isoprene units which are derived from acetyl-CoA. In the hormonally related cancers like breast and prostate cancer, genetics seem to be a much more powerful factor than lifestyle. The disease can be efficiently detected at an early stage by self-examination and mammography. Generally, the vacuole content the cell sap is considered to represent, together with the cytosol, the hydrophilic part of the plant cell. Nutritional polysaccharides include starch, fructans, mannans and galactomannans. Physicians monitor patients closely to determine efficacy and identify adverse reactions. During this period, more than 4,00,000 chemicals, both synthetic and natural, have been screened for antitumor activity Dimitriou, 2001.

Generally, structural polysaccharides are strait-chained not very soluble in water , while nutritional reserve food polysaccharides tend to be branched, therefore forming viscous hydrophilic colloid systems. Conventional cancer treatments Conventional cancer treatments include surgery, radiation and chemotherapy. Chapter I What do we know about cancer and its therapy? Cancer cells fail to adhere and, in addition, they possess the ability to migrate from the site where they began, invading nearby tissues and forming masses at distant sites in the body, via the bloodstream. Plants and cancer 23 Table 2. Introduction: general botanical issues In this chapter a detailed analysis will be given on a number of species with documented anticancer properties either in vitro or in clinical use. Shoots continue to grow at the tip, and develop new leaves, with buds in the axils, which can grow into branches.

Structure and properties: By definition, lipids are soluble only in organic solvents. This kind of treatment also has many side effects, such as nausea, anemia, weakening of the immune system, diarrhea, vomiting and hair loss. The investigator prepares a study action plan, called a protocol. This can be achieved by plant regeneration via organogenesis induction of shoots and roots from callus cultures or somatic embryogenesis the process of embryo formation from somatic sporophytic tissues without fertilization. The patients took 24 shark cartilage capsules a day for three months, but the disease still progressed in 15 and one developed cancer of the brain.

At this point it is worth mentioning that the angiogenesis- inhibitor squalamine is based on dogfish shark liver. An increasing amount of cancer research is being directed towards the investigation of plant-derived anticancer compounds, many of which have been used in traditional herbal treatments for centuries. G The brine shrimp lethality assay for activity-directed fractionation. Most of the drugs discovered during that period, and currently 10 Spiridon E. Annuals complete their life-cycle within a year. In 1990, Fukui et al. They can be separated from a water extract by denaturating proteins in chloroform-octyl alcohol and then precipitate polysaccharides in a weakly basic solution.

Kintzios 2 Leukemia is distinguished in acute lymphocytic common among children , acute myelogenous and chronic lymphocytic leukemia. Some oncogenes force cells to overproduce growth factors, such as the platelet-derived growth factor and the transforming growth factor alpha sarcomas and gliomas. Anthraquinones represent the largest group of natural quinines, are usually hydroxylated at C-1 and C-2 and commonly occur as glycosides water-soluble. Most of these agents have been identified through epidemiological studies, although the exact nature of their activity on a biological level remains obscure. An increasing amount of cancer research is being directed towards the investigation of plant-derived anticancer compounds, many of which have been used in traditional herbal treatments for centuries.
