Lysine l‐Lactylation: Bridging Metabolism, Chromatin and Disease
Enzymatic regulation of KL‐la. The enzymatic regulation of KL‐la involves two distinct pathways for L‐lactate accumulation: intracellular production through glycolysis‐derived pyruvate conversion by lactate dehydrogenase (LDH) or direct cellular uptake via monocarboxylate transporters (MCTs). These L‐lactate pools fuel two distinct lactylation pathways—

Remote Assessment of Ataxia Severity in SCA3 Across Multiple Centers and Time Points
ABSTRACT Objective Spinocerebellar ataxia type 3 (SCA3) is a genetically defined ataxia. The Scale for Assessment and Rating of Ataxia (SARA) is a clinician‐reported outcome that measures ataxia severity at a single time point. In its standard application, SARA fails to capture short‐term fluctuations, limiting its sensitivity in trials.

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...

QBP1 Peptide as a Potential Anti‐Amyloidogenic Therapy for Type 2 Diabetes: An In Vitro Study
The anti‐amyloidogenic peptide QBP1 effectively halts human islet amyloid polypeptide (hIAPP) aggregation, preventing the formation of toxic β‐structured intermediates. Through a combination of biophysical assays, molecular dynamics, and cell‐based studies, QBP1 is shown to preserve β‐cell viability and metabolic homeostasis, positioning it as a ...

Polyglutamine Aggregation in Huntington and Related Diseases [PDF]
Polyglutamine (polyQ)-expansions in different proteins cause nine neurodegenerative diseases. While polyQ aggregation is a key pathological hallmark of these diseases, how aggregation relates to pathogenesis remains contentious. In this chapter, we review what is known about the aggregation process and how cells respond and interact with the polyQ ...

Nuclear dysfunction in aging and neurodegeneration
Abstract Neurodegenerative diseases are characterized by a loss of neuronal function and structure, often in a region‐specific manner. Multiple factors contribute to neuronal dysfunction and death, including pathogenic protein buildup, protein mislocalization, and inflammation. Despite extensive research, the common mechanisms driving neurodegeneration

RNA therapy for polyglutamine neurodegenerative diseases
Polyglutamine neurodegenerative diseases result from the expansion of a trinucleotide CAG repeat, encoding a polyglutamine tract in the disease-causing protein. The process by which each polyglutamine protein exerts its toxicity is complex, involving a variety of mechanisms including transcriptional dysregulation, proteasome impairment and ...

Detection of ubiquitinated huntingtin species in intracellular aggregates
Protein conformation diseases, including polyglutamine diseases, result from the accumulation and aggregation of misfolded proteins. Huntington’s disease is one of nine diseases caused by an expanded polyglutamine repeat within the affected protein and ...
