- mRNA splicing represents a fundamental level of gene regulation that alters proteomic diversity and cellular state. Its dysfunction can profoundly rewire metabolism, yet underlying mechanisms remain elusive. Here, we investigate Verheij syndrome, caused by mutations in core splicing factor PUF60, using a Caenorhabditis elegans model, human cell lines, and patient-derived samples. We demonstrate that RNP-6/PUF60 deficiency disrupts splicing of genes governing one-carbon metabolism and phospholipid remodeling, impairing S-adenosylmethionine/S-adenosylhomocysteine cycling and phosphatidylcholine synthesis. These perturbations trigger the integrated stress response and compromise mTORC1 signaling, causing developmental growth defects. Vitamin B supplementation restores metabolic balance by reactivating S-adenosylmethionine-dependent phospholipid remodeling and mTORC1 activity, effectively rescuing Verheij-like phenotypes. Similar responses arise from perturbing another splicing factor, PRP-19. Mechanistically, intron retention of nhr-114/HNF4 transcription factor drives these phenotypes, while restoring its splicing rescues them. Our findings implicate vitamin B-dependent one-carbon metabolism as a metabolic modulator with therapeutic potential to mitigate Verheij syndrome and other spliceosomopathies. - Source: PubMed

- Pyruvate kinase M (PKM) catalyzes the conversion of phosphoenolpyruvate to pyruvate in glycolysis and exists as two splice isoforms, PKM1 and PKM2, generated from alternative splicing of mutually exclusive exons 9 or 10, respectively. The expression balance between PKM1 and PKM2 is tightly regulated in a cell-type-specific manner. PKM1 is predominantly expressed in tissues such as skeletal muscle, heart, and brain, whereas PKM2 is prevalent in most other tissues and various cancer cells. Despite its importance, the trans-acting factors promoting exon 9 selection in a tissue-specific context remain largely unknown. Here, using a multi-color splicing reporter system for cell-based cDNA screening, we identified PUF60 as a novel -acting factor that promotes PKM1-type splicing. We also demonstrated that PUF60 induction and the resulting splicing switch are essential for myotube formation during C2C12 differentiation. This study establishes PUF60 as a critical regulator of muscle-specific splicing and provides new insights into the fundamental mechanisms governing skeletal muscle differentiation. - Source: PubMed
