Compositions, methods, and kits are provided for diagnosing Parkinson's disease, vitreoretinal diseases, and age-related pathologies. In particular, aqueous humor biomarkers have been identified that correlate with biological aging and age-related pathologies and morbidity. The use of such biomarkers may allow earlier intervention in treatment of aging-related diseases. In addition, methods of using aqueous humor biomarkers for prognosis, diagnosis, and monitoring treatment of Parkinson's disease and vitreoretinal diseases are also provided.

Provided is aptamers screening method based on graphene without target immobilization and the aptamers obtained from the method, and more particularly, a new GO-SELEX method without target immobilization in which a single-stranded nucleic acid pool may react with a non-bound target material or a counter-target material, after which a single-stranded nucleic acid which has not been bound to the target or counter-target may be separated by using the graphene. Also, the specific aptamer obtained through the above-described method may be used for diagnosing target related diseases.

Provided herein are methods for identifying a compound having cell-protective (e.g., neuroprotective) activity. Compounds identified therefrom are also provided. These compounds can be used to treat various diseases, disorders, or conditions associated with, for example, unwanted cell death.

This invention relates to the finding that FAMIN (fatty acid metabolism-immunity nexus; LACC1, C13orf31)) is a trifunctional purine salvage enzyme that displays a unique combination of adenosine deaminase, purine nucleoside phosphorylase and methylthioadenosine phosphorylase activities. Methods of measuring FAMIN activity and screening for FAMIN modulators are provided that comprise determining the adenosine deaminase activity, purine nucleoside phosphorylase activity and/or methylthioadenosine phosphorylase activity of an isolated FAMIN protein.

The present specification relates to methods of treatment of wild type MTAP gene cancers comprising administering a MTA synergistic PRMT5 inhibitor to a patient in need thereof.

The present invention relates to metal nanoparticles and a plasmonic biosensor including the same. According to the present invention, it is possible to provide novel metal nanoparticles having significantly improved sensitivity to light, and further, it is possible to provide a plasmonic biosensor capable of detecting a trace amount of a biomarker present in a biological sample with high precision through the metal nanoparticles. In addition, the plasmonic biosensor is capable of detecting a sepsis biomarker with high sensitivity and specificity, and thus may be usefully used in various clinical applications such as sepsis diagnosis, identification of the type of organ dysfunction, prediction of sepsis severity, and post-treatment.
