  • Publication number: 20260140122
    Abstract: Aspects of the disclosure relate to methods and compositions (e.g., kits) for detecting anti-repeat-associated non-ATG (RAN) protein antibodies in a subject (e.g., a subject that has been administered a therapeutic anti-RAN protein antibody or a vaccine against a disease or disorder associated with RAN protein expression, translation, and/or accumulation, for example amyotrophic lateral sclerosis (ALS) and/or frontotemporal dementia (FTD)). In some embodiments, methods described by the disclosure comprise detecting one or more anti-RAN protein antibodies in a biological sample obtained from a subject by an electrochemiluminescence-based immunoassay using one or more target di-amino acid repeat peptides. In some embodiments, the disclosure relates to kits comprising one or more di-amino acid repeat peptides and an electrochemiluminescence-based immunoassay plate and/or reagents.

  • Publication number: 20250237666
    Abstract: Aspects of the disclosure relate to compositions and methods for the diagnosis and/or treatment of certain neurodegenerative diseases, for example those diseases associated with repeat-associated non-ATG (RAN) translation proteins, such as Alzheimer's disease (AD). In some embodiments, the disclosure relates to identifying a subject having a RAN protein-associated disease by detecting expression or activity of repeat-associated non-ATG (RAN) translation proteins (e.g., RAN proteins). In some embodiments, the disclosure relates to methods of treating a RAN protein-associated disease by administering to a subject in need thereof an agent that reduces expression or activity of RAN proteins.

  • Publication number: 20250164489
    Abstract: Aspects of the disclosure relate to compositions and methods for the diagnosis and/or treatment of C9orf72 negative sporadic amyotrophic lateral sclerosis (C9? sALS). In some embodiments, the disclosure relates to identifying a subject as having C9orf72 negative (C9?) sALS by detecting expression or activity of repeat-associated non-ATG (RAN) translation proteins (e.g., RAN proteins). In some embodiments, the methods and compositions of the disclosure identify certain gene or genes which comprise mutation(s) leading to the expression of the detected RAN proteins, and which were previously unknown to be associated with sALS. In some embodiments, said gene(s) can be used to identify or diagnose subjects having, suspected of having, or at risk of developing sALS which is unrelated to expansion mutations within the C9orf72 and/or SCA36 genetic loci (e.g., C9? sALS).

  • Publication number: 20230031009
    Abstract: The present invention is directed to a method of treatment, including prevention or reducing the likelihood of adverse effects of chemotherapy comprising reducing and/or inhibiting chemotherapy-induced adverse effects (CIAE), especially central nervous system adverse effects, such as cognitive effects (especially chemotherapy induced cognitive impairment or CICI, also referred to as reduced cognition, cognitive impairment or chemobrain) by administering to the patient in need, including co-administering to the subject in need a pharmaceutically effective amount of a protein kinase C (PKC, often, PKC ? and/or ?) inhibitor, alone or in combination with a lithium salt. Related pharmaceutical compositions are also provided by the present invention.
