Abstract:
This study provides evidence for the involvement of the lncRNA Gm12606 in the cellular radiation response, and in particular confirms a very strong role in the ageing process of mouse mesenchymal stem cells (mMSCs). Knockdown of Gm12606 strongly impaired transcription of the nearby Ink4a/Arf/Ink4b locus, suggesting a cis-mediated mechanism. Thus, mMSCs from bone marrow of Gm12606 exon1-deficient homozygous mice resulted in a significantly lower percentage of cellular senescence.
