MATR3 (Matrin-3) is a nuclear matrix protein that forms distinct nuclear bodies (MATR3-NBs) functioning as RNA processing hubs for spliceosome recycling and transcription termination. This hypothesis proposes that ALS-linked MATR3 mutations (p.S85C, p.F115C, p.G497E) disrupt MATR3-NB integrity, causing aberrant spliceosome dynamics, intron retention accumulation, and nuclear RNA export defects that trigger motor neuron death. The mechanistic prediction is that MATR3-NBs serve as transient storag
This hypothesis proposes that TBK1 loss-of-function mutations drive ALS pathogenesis by inducing senescence in astrocytes, which then propagate senescent signals to motor neurons through SASP-mediated paracrine mechanisms, ultimately causing neuronal dysfunction and death. Supporting evidence includes the 2025 Nat Commun study showing that TBK1 deletion creates an aged-like transcriptional signature with increased inflammatory gene expression, suggesting cellular senescence induction.
