Indicators of altered mitochondrial function in predictive methods for determining risk of type 2 diabetes mellitus

A method for determining a degree of disease progression in a human subject having Type 2 diabetes, comprising:

• comparing the level of at least one indicator of altered mitochondrial function in each of first and second biological samples, said first and second biological samples being obtained from said subject at a first time point and a second time point, respectively;
• and therefrom determining the degree of progression of Type 2 diabetes, wherein the indicator of altered mitochondrial function is selected from the group consisting of (i) a Krebs cycle enzyme, wherein said enzyme is an acetyl-coenzyme A carboxylase that is selected from the group consisting of acetyl-coenzyme A carboxylase-1 and acetyl-coenzyme A carboxylase-2, and (ii) an ATP biosynthesis factor, wherein said factor is human acetyl-coenzyme A carboxylase-2.

A method of identifying an agent suitable for treating a human subject suspected of being at risk for having type 2 diabetes, comprising:

• comparing the level of at least one indicator of altered mitochondrial function in one or more biological samples obtained from the subject in the presence and absence of a candidate agent;
• and therefrom determining the suitability of said candidate agent for treating type 2 diabetes, wherein the indicator of altered mitochondrial function is selected from the group consisting of (i) a Krebs cycle enzyme, wherein said enzyme is an acetyl-coenzyme A carboxylase that is selected from the group consisting of acetyl-coenzyme A carboxylase-1 and acetyl-coenzyme A carboxylase-2, and (ii) an ATP biosynthesis factor, wherein said factor is human acetyl-coenzyme A carboxylase-2.

A method of determining the suitability of an agent for treating a subject suspected of being at risk for having type 2 diabetes, comprising:

• comparing the level of at least one indicator of altered mitochondrial function in a biological sample obtained from the subject before and after administering to said subject a candidate agent;
• and therefrom determining the suitability of said candidate agent for treating type 2 diabetes, wherein the indicator of altered mitochondrial function is selected from the group consisting of (i) a Krebs cycle enzyme, wherein said enzyme is an acetyl-coenzyme A carboxylase that is selected from the group consisting of acetyl-coenzyme A carboxylase-1 and acetyl-coenzyme A carboxylase-2, and (ii) an ATP biosynthesis factor, wherein said factor is human acetyl-coenzyme A carboxylase-2.

A method of determining the suitability of an agent for treating a human subject suspected of being at risk for having type 2 diabetes, comprising:

• comparing the level of at least one indicator of altered mitochondrial function in at least one biological sample obtained from a plurality of subjects before and after administering to each of said subjects a candidate agent;
• and therefrom determining the suitability of said candidate agent for treating type 2 diabetes, wherein the indicator of altered mitochondrial function is selected from the group consisting of (i) a Krebs cycle enzyme, wherein said enzyme is an acetyl-coenzyme A carboxylase that is selected from the group consisting of acetyl-coenzyme A carboxylase-1 and acetyl-coenzyme A carboxylase-2, and (ii) an ATP biosynthesis factor, wherein said factor is human acetyl-coenzyme A carboxylase-2.

A method of stratifying human subjects according to type 2 diabetes subtypes, comprising:

• comparing the level of at least one indicator of altered mitochondrial function in at least one biological sample obtained from each of a plurality of subjects;
• and therefrom stratifying said subjects according to type 2 diabetes subtype, wherein the indicator of altered mitochondrial function is selected from the group consisting of (i) a Krebs cycle enzyme, wherein said enzyme is an acetyl-coenzyme A carboxylase that is selected from the group consisting of acetyl-coenzyme A carboxylase-1 and acetyl-coenzyme A carboxylase-2, and (ii) an ATP biosynthesis factor, wherein said factor is human acetyl-coenzyme A carboxylase-2.

A method of stratifying human subjects according to type 2 diabetes subtypes, comprising:

• comparing the level of at least one indicator of altered mitochondrial function in a biological sample obtained from each of a plurality of subjects before and after administering to each of said subjects a candidate agent;
• and therefrom stratifying said subjects according to type 2 diabetes subtype, wherein the indicator of altered mitochondrial function is selected from the group consisting of (i) a Krebs cycle enzyme, wherein said enzyme is an acetyl-coenzyme A carboxylase that is selected from the group consisting of acetyl-coenzyme A carboxylase-1 and acetyl-coenzyme A carboxylase-2, and (ii) an ATP biosynthesis factor, wherein said factor is human acetyl-coenzyme A carboxylase-2.

A method of treating a human patient having type 2 diabetes mellitus, comprising administering to the patient an agent that substantially restores to a normal level at least one indicator of altered mitochondrial function, wherein the indicator of altered mitochondrial function is selected from the group consisting of (i) a Krebs cycle enzyme, wherein said enzyme is an acetyl-coenzyme A carboxylase that is selected from the group consisting of acetyl-coenzyme A carboxylase-1 and acetyl-coenzyme A carboxylase-2, and (ii) an ATP biosynthesis factor, wherein said factor is human acetyl-coenzyme A carboxylase-2.
