Publication number: 20260140122Abstract: 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.Type: ApplicationFiled: September 11, 2025Publication date: May 21, 2026Applicant: University of Florida Research Foundation, IncorporatedInventors: Laura Ranum, Lauren A.

Patent number: 12504380Abstract: Aspects of the disclosure relate to methods and compositions (e.g., kits) for detecting repeat-associated non-ATG (RAN) proteins in a subject (e.g., a subject having or suspected of having a disease associated with RAN protein translation, for example amyotrophic lateral sclerosis (ALS) and/or frontotemporal dementia (FTD), or spinocerebellar ataxia type 36 (SCA36), or other diseases that produce poly(PR), poly(GR) or poly(GP) RAN proteins. In some embodiments, methods described by the disclosure comprise detecting one or more RAN proteins in a biological sample obtained from a subject by an electrochemiluminescence-based immunoassay using one or more anti-RAN protein antibodies. In some embodiments, the disclosure relates to kits comprising one or more anti-RAN antibodies and an electrochemiluminescence-based immunoassay plate and/or reagents.Type: GrantFiled: September 25, 2018Date of Patent: December 23, 2025Assignee: University of Florida Research Foundation, IncorporatedInventors: Laura Ranum, Lien Nguyen

Publication number: 20250237666Abstract: 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.Type: ApplicationFiled: November 1, 2022Publication date: July 24, 2025Applicant: University of Florida Research Foundation, IncorporatedInventors: Laura Ranum, Lien Nguyen

Publication number: 20250164489Abstract: 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).Type: ApplicationFiled: February 27, 2023Publication date: May 22, 2025Applicant: University of Florida Research Foundation, IncorporatedInventors: Laura Ranum, Lien Nguyen, Shu Guo

Publication number: 20230031009Abstract: 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.Type: ApplicationFiled: February 11, 2021Publication date: February 2, 2023Inventors: Barbara Ehrlich, Lien Nguyen
