Abstract: Described herein are methods for identifying mitochondrial defects using metabolomics and genetic analyses and using this information to stratify patients and to correct for metabolic defects in a precision medicine approach. One embodiment is a method for isolating and analyzing samples containing one or more mitochondrial biomarker metabolites or genetic markers useful for the analysis, identification, stratification or classification, and treatment of metabolic changes associated with a CNS or neuropsychiatric disease in a subject and therapies useful for the treatment thereof. In one aspect, the biomarker metabolites comprise mitochondrial metabolites including acylcarnitines and endocannabinoids and the genetic analyses focus on metabolic enzymes or transport mechanisms.

Abstract: Described herein are methods for identifying or diagnosing Alzheimer's disease or poor cognition in a subject or population of subjects by analyzing biomarkers. In one aspect, the biomarkers comprise liver function enzymes or metabolites including alanine aminotransferase (ALT), aspartate aminotransferase (AST), ratio of ALT to AST, alkaline phosphatase, albumin, bilirubin, cholesterol and cholesterol metabolites, amino acids, phospholipids, bile acids, or other metabolites. In another aspect, the biomarkers comprise alanine aminotransferase (ALT), aspartate aminotransferase (AST), or the ratio of ALT to AST levels. In another aspect, the marker comprises the genotype of the ALT or AST enzymes.

Abstract: Embodiments of the present disclosure relate generally to the analysis and identification of global metabolic changes in Alzheimer's disease (AD). More particularly, the present disclosure provides materials and methods relating to the use of metabolomics as a biochemical approach to identify peripheral metabolic changes in AD patients and correlate them to cerebrospinal fluid pathology markers, imaging features, and cognitive performance. Defining metabolic changes during AD disease trajectory and their relationship to clinical phenotypes provides a powerful roadmap for drug and biomarker discovery.

Abstract: A method of assessing the level of triglycerides in the liver of a subject comprises determining the amount of a first lipid metabolite in a sample from the subject. The sample can be blood, plasma, serum, isolated lipoprotein fraction, saliva, urine, lymph fluid, bile, or cerebrospinal fluid. The first lipid metabolite is a fatty acid present in a lipid class. The lipid class is selected from the group consisting of free fatty acids, total fatty acids (TL), triglycerides (TG), cholesterol esters (CE), phosphatidylcholines (PC), and phosphatidylethanolamines (PE).

Abstract: Novel methods for assessing the level of triglycerides in the liver of a subject are described, comprising determining the amount of a lipid metabolite in a sample from a body fluid of the subject. The methods may be used, for example, in diagnosing and monitoring liver disorders such as steatosis, NAFLD and NASH.

Abstract: The present invention concerns the application of lipidomics to statin treatment for disorders such as cardiovascular disorders. Hence, the invention provides, among other things, a method of correlating a lipid profile with a positive or negative response to a statin treatment regimen by obtaining a lipid profile of a sample from a mammalian subject following commencement of the treatment regimen; and correlating the lipid profile in the sample with a positive or negative response to the treatment regimen. The invention further provides a method of correlating a lipid profile with a positive or negative response to a statin treatment regimen by obtaining a lipid profile of a sample from a mammalian subject before commencement of the treatment regimen; and correlating the lipid profile in the sample with a positive or negative response to the treatment regimen.

Abstract: The present invention provides metabolic markers and targets, especially PEMT activity and metabolic markers and components associated therewith useful for diagnosing and treating various disease conditions.
