It has been newly found that 105 proteins as set forth in SEQ ID NOS: 1 to 105 are significantly over-expressed in the vitreous humors obtained from PDR patients, while 64 proteins as set forth in SEQ ID NOS: 106 to 169 are significantly over-expressed in those obtained from normal people. Therefore, the proteins can be used for biomarker capable of detecting diabetic retinopathy. The biomarker can provide fundamental information in researching vitreoretinal disorders, such as diabetic retinopathy. Especially, the newly found proteins may be applied to a kit for diagnosing diabetic retinopathy with a molecule specifically binding thereto, e.g., a monoclonal antibody. And also, it has been newly found that the levels of thyroxine-binding globulin precursor (TBG) in both vitreous and plasma of PDR and NPDR states and in plasma of diabetes mellitus state, are outstandingly higher than in non-diabetic control (MH or normal control). Therefore, TBG may be applied to a diabetes mellitus biomarker, and a kit for diagnosing diabetes mellitus with a molecule specifically binding thereto. | 07-15-2010 |
