Human blood molecular biodosimeter panel for distinguishing radiation exposure from inflammation stress
View Patent ↗Panels of 8-, 9- and 12-biomarker for diagnostic and prognostic methods to determine a subject's radiation exposure and discriminates between persons who have been exposed to radiation only, inflammation stress only, or a combination of the two.
1. A kit comprising (a) nucleic acid probes for detection of expression levels of a gene panel consisting of eight DNA repair genes, CDKN1A, FDXR, BBC3, PCNA, GADD45a, XPC, POLH and DDB2, wherein said probes provide for assessment of a subject's radiation exposure and discriminates between persons who have been exposed to radiation only, inflammation stress only, or a combination of the two, wherein the probes are displayed on a surface, and (b) an antibody probe for detection of pCHK2-thr68.
2. A kit comprising (a) nucleic acid probes for detection of expression levels of a gene panel consisting of twelve DNA repair genes consisting of CDKN1A, FDXR, BBC3, PCNA, GADD45a, XPC, POLH, DDB2, CCNG1, BAX, LIG1, and RAD51, wherein said probes provide for assessment of a subject's radiation exposure and discriminates between persons who have been exposed to radiation only, inflammation stress only, or a combination of the two, wherein the probes are displayed on a surface, and (b) an antibody probe for detection of pCHK2-thr68.
3. A kit comprising antibody probes for detection of expression levels of a panel consisting of eight DNA repair proteins, CDKN1A, FDXR, BBC3, PCNA, GADD45a, XPC, POLH and DDB2 or twelve DNA repair proteins, CDKN1A, FDXR, BBC3, PCNA, GADD45a, XPC, POLH, DDB2, CCNG1, BAX, LIG1, and RAD51, wherein said probes provide for assessment of a subject's radiation exposure and discriminates between persons who have been exposed to radiation only, inflammation stress only, or a combination of the two; wherein the antibody probes are each fixed separately on a substrate.
4. A kit comprising antibody probes for detection of expression levels of a panel consisting of (a) eight DNA repair proteins, CDKN1A, FDXR, BBC3, PCNA, GADD45a, XPC, POLH and DDB2 or twelve DNA repair proteins, CDKN1A, FDXR, BBC3, PCNA, GADD45a, XPC, POLH, DDB2, CCNG1, BAX, LIG1, and RAD51, and (b) pCHK2-thr68; wherein said probes provide for assessment of a subject's radiation exposure and discriminates between persons who have been exposed to radiation only, inflammation stress only, or a combination of the two; wherein the antibody probes are each fixed separately on a substrate.
5. The kit of claim 3 , wherein the panel consists of twelve DNA repair proteins, CDKN1A, FDXR, BBC3, PCNA, GADD45a, XPC, POLH, DDB2, CCNG1, BAX, LIG1, and RAD51.
