Acetyl-L-carnitine (ALCAR) and L-carntine (LCAR) are nutraceuticals with indications in treating a variety of mental health disorders. A metabolomics-guided bioprocess method is presented to enhance ALCAR and LCAR formation in germinating plant seeds. Metabolic fluxes are manipulated by germination in bioreactors to increase oxygen availability as well as provide an aseptic environment to alter carbohydrate consumption and feedback repress gluconeogenesis. Large shifts in sunflower seed fatty acid, phospholipid and high-energy metabolism change the germination environment and these metabolic changes lead to an approximate 1000-fold increase in natural LCAR and ALCAR production by the seeds. The resulting LCAR and ALCAR products from the seeds are used for treating mental health disorders including Alzheimer's disease, geriatric depression, non-geriatric depression and schizophrenia.

A method of treatment of cancer with a formulation of liposomally encapsulated glutathione, that is preferably used orally, increases the level of glutathione in tissues in order to prevent and reverse the metabolic changes in cells that results in the formation of the metabolic “fuel supply” that supports cancer cells, and without which the cells can die out. The method prevents the oxidative stress that damages normal support cells such as stromal fibroblast cells. By blocking the “fuel supply,” the invention can protect, prevent and reverse these cells from the steps of autophagy and mitophagy, that results in the cells decreasing the normal production of ATP for energy and using aerobic glycolysis for energy production. The use of oral liposomally encapsulated glutathione will maintain the presence and normal function of caveolin in fibroblast and other cells, thus preventing their conversion to autophagic tumor stromal cells.

This invention provides a system for rapid determination of pharmacologic effects on target tissue types in cell populations cultured in vitro. The cells contain a promoter-reporter construct that reflects a toxicologic or metabolic change caused by the agent being screened. The promoter is taken from a gene known to be up- or down-regulated according to the metabolic state of the cell, and linked to a reporter gene that provides an external signal for monitoring promoter activity. The promoter-reporter cells may be produced by placing these genetic alterations into a line of human embryonic stem cells, bulking up the cells to any extent desired, and then differentiating the cells into the desired tissue type. This disclosure explains some of the powerful features of the promoter-reporter cells of this invention, and shows various ways the skilled reader can use the invention for pharmaceutical development and testing, or to monitor graft survival.
