Agents and mechanisms for treating hypercholesterolemia
A method of treating hypercholesterolemia in mammals, by administering an effective amount of a microbial fermentation product, and regulating genes involved in lipoprotein metabolism. A method of regulating cholesterol levels in a patient by administering an effective amount of a composition chosen from the group consisting of PAZ, specific components isolated from PAZ, chemically synthesized analogues of the components of PAZ, and regulating genes involved in lipoprotein metabolism. A method of treating high cholesterol levels in an individual by administering an effective amount of a microbial fermentation product, up-regulating the expression of at least one of the genes that encode ABCA1, ApoA1, and SRB1, and down-regulating the gene that encodes CETP. A method of preventing the onset of high cholesterol levels and/or a deleterious lipoprotein profile in an individual.
1. A method of preventing the onset of high cholesterol in an individual, the method comprising:
administering to the individual in need thereof an effective amount of a fraction of a PAZ culture filtrate chosen from the group consisting of PF3 and PF4, wherein the PAZ culture filtrate comprises an algae culture filtrate extracted from a freshwater culture of the organisms found within ATCC Deposit # PTA-5863, wherein the PF3 fraction is a chromatographically separated fraction of the PAZ culture filtrate obtained by strong cationic ion exchange chromatographic separation of the algae culture filtrate, wherein the PF4 fraction is obtained by passing the algae culture filtrate through a series of chromatographic columns consisting of, in sequence: (i) a weak anionic ion exchange chromatography column; (ii) a strong anionic ion exchange chromatography column; (iii) a strong cationic ion exchange chromatography column;
and (iv) a C 18 derivatized chromatography column, and collecting the PF4 fraction as a liquid that flows through the complete series of chromatography columns, and wherein the fraction regulates one or more genes involved in lipoprotein metabolism in the individual.
2. The method of claim 1 , wherein the fraction is a liquid for oral consumption.
3. The method of claim 1 , wherein the fraction is a nutraceutical.
4. The method of claim 3 , wherein the fraction is a food additive.
5. The method of claim 1 , wherein the fraction is administered daily.
6. The method of claim 1 , wherein the fraction up-regulates the expression of at least one of the genes that encode ABCA1, ApoA1, or SR-B 1.
7. The method of claim 1 , wherein the fraction down-regulates the expression of a gene that encodes CETP.
8. The method of claim 1 , wherein the PF3 fraction up-regulates expression of a gene that encodes ApoA1.
9. The method of claim 1 , wherein the PF 4 fraction up-regulates expression of genes that encode ABCA1 and SR-B1, and down-regulates expression of a gene that encodes CETP.
