The contribution of transcriptome dynamics to the establishment of juvenile properties remains unclear. Here, we investigated alternative splicing (AS) events in postnatal growth and elucidated the landscape of age-dependent alternative splicing (ADAS) in C57BL/6 mice. Our analysis of ADAS in the cerebral cortex, cardiomyocytes, and hepatocytes revealed numerous juvenile-specific splicing isoforms that shape the juvenile transcriptome, which in turn functions as a basis for the highly anabolic status of juvenile cells. Mechanistically, the juvenile-expressed splicing factor Srsf7 mediates ADAS, as exemplified by switching from juvenile to adult forms of anabolism-associated genes Eif4a2 and Rbm7. Suppression of Srsf7 results in "fast-forwarding" of this transcriptome transition, causing impaired anabolism and growth in mice. Thus, juvenile-specific AS is indispensable for the anabolic state of juveniles and differentiates juveniles from adults., Journal Article}, title = {Srsf7 Establishes the Juvenile Transcriptome through Age-Dependent Alternative Splicing in Mice.}, volume = {23}, year = {2020} }
