Biomarkers related to metabolic age and methods using the same
View Patent ↗Biomarkers relating to metabolic age are provided, as well as methods for using such biomarkers as biomarkers for determining metabolic age. In addition, methods for modulating the metabolic age of a subject are also provided. Also provided are suites of small molecule entities as biomarkers for metabolic age.
1. A method for determining the metabolic age of a subject comprising the steps of:
a) analyzing a biological sample from a subject to determine the level(s) of glycine and one or more biomarkers for metabolic age in the sample, wherein the one or more biomarkers are selected from the group consisting of alanine, glutamine, normetanephrine, ornithine and valine and
b) comparing the level(s) of glycine and the one or more biomarkers in the sample to metabolic age reference levels of glycine and the one or more biomarkers to determine the subject's metabolic age.
2. The method of claim 1 , wherein the level(s) of the one or more biomarkers in the sample are compared to a biochemical age index to determine the subject's metabolic age.
3. The method of claim 1 , wherein levels of glycine and the one or more biomarkers in the sample are similar to metabolic age reference levels corresponding to an older chronological age are indicative of a negative metabolic age.
4. The method of claim 1 , wherein levels of glycine and the one or more biomarkers in the sample are similar to metabolic age reference levels corresponding to a younger chronological age are indicative of a positive metabolic age.
5. The method of claim 1 , wherein the biological sample is blood plasma.
6. The method of claim 1 , wherein the reference level(s) are tailored to a population selected from the group consisting of gender, race and combinations thereof.
7. The method of claim 1 , wherein said subject is a male subject.
8. The method of claim 1 , wherein said subject is a female subject.
