Benefits of technology

[0010] In a further embodiment, the composition is used for at least one of the following purposes: athletic performance enhancement, as a protease inhibitor, to prevent muscle atrophy, for anti-aging purposes, as an HIV medication, for the treatment of Cushings disease, for the treatment of cachexia, for the prevention of muscle wasting, for the build-up of muscle mass; for the treatment of Addison's disease, muscular dystrophy, multiple sclerosis, type I diabetes, type II diabetes, rheumatoid arthritis, Crohn's disease, ulcerative colitis, irritable bowel syndrome, other autoimmune disorders, burns, joint injury, immobilization, coma, dislocations, gastrointestinal disorders, cancer, HIV, AIDS, sarcopenia, spinal cord damage, nerve damage, TGF alpha and beta disorders, ALS, vision disorders, weak muscles, ankolosing spondilitis, anorexia, bulimia, corticosteroid use, growth factor disorders, dysphasia, SIV, body dysmorphia, low androgen levels, menstruation problems, infertility, hypo- or hyper-thyroidism, catacholamine surge, low FSH, low LH, low GRH, low HCG, and viral infections; in conjunction with surgery and / or joint replacement operations; for the improvement of weight and / or muscle mass in livestock; to raise follistatin levels in a mammal (including a human); to lower myostatin levels in a mammaol (including a human); and combinations thereof.

Problems solved by technology

One of the most devastating but least-discussed aspects of age-related decline is the onset of frailty, i.e., the progressive loss of robustness in multiple tissues and organ systems.

Determination of Follistatin Levels in Chicken Eggs

[0169] To determine the follistatin levels in conventional fertilized and non-fertilized conventional store bought chicken eggs were obtained and follistatin levels in the eggs were determined via immobilizing follistatin via binding to Activin in a C18 HPLC column (ExpertTox, Inc., Deer Park, Tex.). The assay was standardized with Recombinant Follistatin 288 and was assayed in an LC / MS with a third degree fragmentation (D. S., Tanetta, et al. 1977). Results revealed all fertile eggs contained significant concentrations of follistatin (0.11, 1.05. 0.67. and 0.81 mcg / mg) whereas two unfertilized eggs that were also tested contained no detectable follistatin (0 and 0 mcg / mg).

Measurement of Follistatin Levels in Humans

[0170] The following assay was then conducted to determine whether orally ingested naturally occurring follistatin is absorbed and is pharmaco-kinetically active in a human model. A male subject was chosen because the normal baseline male physiology does not regularly contain any measurable concentration of follistatin.

[0171] Follistatin-rich fertile egg yolk powder properly processed to preserve active follistatin (Folstaxan™) was obtained (Celldyne Biopharma, San Antonio, Tex.). After initial blood draw and subsequent oral Folstaxan™ dosing, serum follistatin levels were qualitatively and quantitatively measured as an indicator of absorption. Because follistatin is a negative modulator of myostatin, serum myostatin levels were qualitatively and quantitatively measured as an indicator hormonal influence and thus true pharmacokinetic activity. Testing utilized a purchased follistatin and myostatin standard for verification. Confirmations ...

Effect of Pasteurization of Fertilized Egg Yolks on Follistatin

[0173] Fertile egg yolks contain significant concentrations of follistatin. Egg products are usually pasteurized in order to minimize danger of microbe ingestion. In an effort to identify whether pasteurization denatures or affects this source of naturally occurring follistatin, this study was undertaken.

[0174] Fertile chicken eggs were cracked and separated using commercial breakers and separators. The separated yolk was then pasteurized a HTST at 192 F (89C) for 1.75 minutes. The egg yolks were tested for quantity and quality of active follistatin. Testing utilized purchased follistatin standardized for verification. Confirmations were run by ELISA and quantitations by Liquid Chromatography Tandem Mass Spectrometer with third degree fragmentation (Expertox, Deer Park, Tex.).

[0175] Results showed no measurable active or viable follistatin. This compares with previous results follistatin levels of 0.11 to 1.05 mcg / mg ...
