After a time, certain colonies began to grow. However, the EbgA protein is an ineffective lactase and does not allow growth on lactose. Two classes of single point mutations dramatically improve the activity of ebg enzyme toward lactose. [24] [25] and, as a result, the mutant enzyme is able to replace the lacZ β-galactosidase. [26]
Anti-cancer psychotherapy – a technique [131] claiming that a "cancer personality" caused cancer, which could be cured through talk therapy (e.g. that of the Simonton Cancer Center, [132] Bernie Siegel's "Exceptional Cancer Patients" (ECaP) or Deepak Chopra). Evidence is lacking that cancer cures sold or promoted by Deepak Chopra have any value.
Lactase (EC 3.2.1.108) is an enzyme produced by many organisms and is essential to the complete digestion of whole milk. It breaks down the sugar lactose into its component parts, galactose and glucose. Lactase is found in the brush border of the small intestine of humans and other mammals.
Substrate reduction therapy is FDA approved and there is at least one treatment available on the market. [10] Gene therapy aims to replace a missing protein in the body through the use of vectors, usually viral vectors. [11] In gene therapy, a gene encoding for a certain protein is inserted into a vector. [11]
The hydrolysis of lactose to glucose and galactose is catalyzed by the enzymes lactase and β-galactosidase. The latter is produced by the lac operon in Escherichia coli. [12] In nature, lactose is found primarily in milk and milk products. Consequently, various food products made with dairy-derived ingredients can contain lactose. [13]
1900 – Swedish Dr. Stenbeck cures a skin cancer with small doses of radiation [4]; 1920s – Dr. William B. Coley's immunotherapy treatment, regressed tumors in hundreds of cases, the success of Coley's Toxins attracted heavy resistance from his rival and supervisor, Dr. James Ewing, who was an ardent supporter of radiation therapy for cancer.
Lactase enzymes similar to those produced in the small intestines of humans are produced industrially by fungi of the genus Aspergillus. The enzyme, β-galactosidase, is available in tablet form in a variety of doses, in many countries without a prescription. It functions well only in high-acid environments, such as that found in the human gut ...
A similar mixture of enzymes is sold as pancrelipase, which contains more active lipase enzyme than does pancreatin. The trypsin found in pancreatin works to hydrolyze proteins into oligopeptides; amylase hydrolyzes starches into oligosaccharides and the disaccharide maltose; and lipase hydrolyzes triglycerides into fatty acids and glycerols.
