Abstract
The present disclosure relates to methods of detecting gene expression in a biological sample from an animal. More specifically, this disclosure relates to methods of detecting risk for a catastrophic injury in an animal, such as a non-human athletic animal, based on the expression of select genes within a biological sample from the animal, which can be determined using mRNA expression analysis.
Claims10
A method of detecting biomarker expression indicative of increased risk for catastrophic injury in a non-human athletic animal, comprising:
- (a) obtaining a blood sample from a subject horse;
- (b) detecting in the blood sample from the subject horse the mRNA expression level of at least one of interleukin 1 receptor antagonist (IL1RN), insulin-like growth factor (IGF-1), and matrix metallopeptidase 2 (MMP2);
- and
- (c) detecting at least one of
- (i) a decreased mRNA expression level of IL1RN in the blood sample obtained from the subject horse relative to a control expression level of IL1RN from one or more control blood samples obtained from one or more control horses without catastrophic injury,
- (ii) an increased mRNA expression level of IGF-1 in the blood sample obtained from the subject horse relative to a control expression level of IGF-1 from the one or more control blood samples obtained from the one or more control horses without catastrophic injury, and
- (iii) an increased mRNA expression level of MMP2 in the blood sample obtained from the subject horse relative to a control expression level of MMP2 from the one or more control blood samples obtained from the one or more control horses without catastrophic injury;
- (d) identifying the subject horse as being at risk for catastrophic injury based on the detection of the at least one of the decreased mRNA expression level of IL1RN in the blood sample obtained from the subject horse, the increased mRNA expression level of IGF-1 in the blood sample obtained from the subject horse, and the increased mRNA expression level of MMP2 in the blood sample obtained from the subject horse;
- and
- (e) treating the subject horse subsequent to being identified as at risk for catastrophic injury;
- wherein treating the subject horse includes implementing advanced diagnostics to localize potential injury locations.

A method for detecting biomarker expression indicative of increased risk for catastrophic injury in a non-human athletic animal, comprising:
- (a) obtaining a first blood sample from a subject horse;
- (b) detecting in the first blood sample from the subject horse the mRNA expression level of at least one of interleukin 1 receptor antagonist (IL1RN), insulin-like growth factor (IGF-1), and matrix metallopeptidase 2 (MMP2);
- (c) obtaining a second blood sample from the subject horse at a time subsequent to when the first blood sample was obtained;
- and
- (d) detecting in the second blood sample the mRNA expression level of at least one of IL1RN, IGF-1, and MMP2;
- and
- (e) detecting at least one of
- (i) a decreased level of IL1RN in the second blood sample obtained from the subject horse relative to the expression level of IL1RN in the first blood sample,
- (ii) an increased level of IGF-1 in the second blood sample obtained from the subject horse relative to the expression level of IGF-1 in the first blood sample, and
- (iii) an increased level of MMP2 in the second blood sample obtained from the subject horse relative to the expression level of MMP2 in the first blood sample;
- (f) identifying the subject horse as being at risk for catastrophic injury based on the detection of the at least one of the decreased mRNA expression level of IL1RN in the second blood sample obtained from the subject horse, the increased mRNA expression level of IGF-1 in the second blood sample obtained from the subject horse, and the increased mRNA expression level of MMP2 in the second blood sample obtained from the subject horse;
- (g) treating the subject horse subsequent to being identified as at risk for catastrophic injury;
- wherein treating the subject horse includes implementing advanced diagnostics to localize potential injury locations.
