Vitamin B(12) alleviates spliceosomopathy via phospholipid remodeling
Vitamin B12 restores RNA processing defects linked to aging, suggesting nutritional status may influence age-related cellular dysfunction.
This Nature Communications study identifies a previously unknown function of vitamin B12: promoting phospholipid remodeling that restores spliceosome function in organisms with spliceosomopathy, a class of aging-associated RNA processing defects. The findings open a new avenue connecting B12 nutritional status to spliceosomal integrity, with potential implications for age-related splicing dysregulation in human tissues.

Why it surfaced
Highly novel mechanism (B12 → phospholipid remodeling → spliceosome rescue) from the Antebi lab (Max Planck Institute for Biology of Ageing) published in Nature Communications; spliceosomopathy is emerging as a major mechanism of aging and neurodegeneration; basic science only with no human data limits clinical translation confidence; open access.
