Markers of the male urogenital tract
Methods for detecting urogenital conditions or urogenital status in a subject are described comprising measuring urogenital markers or polynucleotides encoding the markers in a sample from the subject. The invention also provides localization or imaging methods for urogenital conditions, and kits for carrying out the methods of the invention. The invention also contemplates therapeutic applications for urogenital conditions employing urogenital markers, polynucleotides encoding the markers, and/or binding agents for the markers.
1. A method for diagnosis of a urogenital condition in a subject comprising:
(a) contacting a sample of seminal plasma from the subject with an antibody capable of detecting a urogenital marker ECM1 in the sample using an enzyme linked immunosorbent assay (ELISA); and
(b) diagnosing the urogenital condition by detecting a change in the amount or status of the urogenital marker as compared to the amount or status of the same urogenital marker obtained from a control subject who does not suffer from the urogenital condition or a post-vasectomy subject,
wherein the urogenital condition is non-obstructive azoospermia (NOA) or obstructive azoospermia (OA).
2. A method of claim 1 wherein the contacting step further comprises an antibody capable of detecting urogenital marker TEX101 and an antibody capable of detecting urogenital marker LDHC and the method differentiates NOA from OA.
3. A method of claim 1 , wherein the contacting step further comprises at least one additional antibody, each antibody capable of detecting one of the urogenital markers PTGDS, CEL, MUC15, SPAG11B, ALDH1A1, GPR64, CA4 and ADAM7.
4. A method of claim 1 , wherein the contacting step further comprises at least one additional antibody, each antibody capable of detecting one of the urogenital markers CRISP1, FAM12B, SPINT3, CAMP, PTGDS, CES7, ADAM7, MGAM, SPAG11B, MUC15, CEL, NPC2, CA4 and GPR64.
5. A method of claim 1 , wherein the contacting step further comprises at least one additional antibody, each antibody capable of detecting one of the urogenital markers ADAM7, ALDH1A1, CA4, CAMP, CD177, CEL, CES7, CRISP1, FAM12B, GPR64, MGAM, MUC15, NPC2, PTGDS, SPAG11B and SPINT3.
6. A method of claim 1 , wherein the contacting step further comprises an antibody capable of detecting the urogenital marker TEX101.
7. A method of claim 1 , wherein the contacting step further comprises an antibody capable of detecting the urogenital marker LDHC.
8. A method for diagnosing non-obstructive azoospermia (NOA) or obstructive azoospermia (OA) in a male subject, the method comprising:
analyzing, in vitro, the level of expression of ECM1 in a sample from a human subject in an enzyme-linked immunosorbent assay;
and correlating a diagnosis of NOA or OA with a change in the level of expression of ECM 1 in the sample relative to a level of expression of ECM1 in a control subject who does not suffer from NOA or a post-vasectomy subject.
9. A method of claim 8 , further comprising:
analyzing the level of expression of TEX101 in the sample and correlating a diagnosis of NOA or OA with a change in the level of expression each of TEX101 and ECM1 in the sample relative to a level of expression each of TEX101 and ECM1 in the control subject.
10. A method for diagnosis of a urogenital condition in a male subject, wherein the urogenital condition is characterized by the presence of ECM1 biomarker comprising:
(a) obtaining a biological sample from the subject;
(b) applying an antibody specific for ECM1 to the sample, wherein the presence of ECM1 biomarker creates an antibody-ECM1 biomarker complex;
(c) applying a detection agent that detects the antibody-ECM1 biomarker complex; and
(d) diagnosing the urogenital condition by detecting a change in the amount of antibody-ECM1 biomarker complex as compared to the amount of antibody-ECM1 biomarker complex in a sample obtained from a control subject who does not suffer from the urogenital condition or a post-vasectomy subject,
wherein the urogenital condition is non-obstructive azoospermia (NOA) or obstructive azoospermia (OA).
11. A method of claim 10 , further comprising:
applying an antibody specific for TEX101 to the sample, wherein the presence of TEX101 biomarker creates an antibody-TEX101 biomarker complex;
applying a second detection agent that detects the antibody-TEX101 biomarker complex; and
diagnosing the urogenital condition by detecting a change in the amount of antibody-TEX101 biomarker complex as compared to the amount of antibody-TEX101 biomarker complex in the control sample and a change in the amount of antibody-ECM1 biomarker complex as compared to the amount of antibody-ECM1 biomarker complex in the control sample.
