Non canonical Drosha pathway regulates hippocampal neural stem cell differentiation
Embryology and Stem Cell Biology, Department of Biomedicine - University of Basel
Self-renewing and multipotent neural stem cells (NSCs) reside in the dentate gyrus of the adult mammalian hippocampus. The Microprocessor, a multimeric complex of the ribonuclease Drosha and the RNA binding protein DGCR8, drives miRNA biogenesis.
The Microprocessor also has miRNA-independent functions, directly targeting and cleaving stem-loop hairpin structures of mRNAs and destabilizing the transcripts. We found that RNAse III Drosha regulates NSC maintenance and inhibits oligodendrocyte fate commitments in adult NSCs.
Drosha-CLIP (cross-linking and immunoprecipitation) experiment shows that Drosha binds the mRNAs of critical oligodendrocyte and gliogenic transcription factors. Taken together our findings reveal a new miRNA-independent action of the Microprocessor in the maintenance of adult NSCs and control of oligodendrocyte differentiation.

Events & Meetings
Our young researchers present their work to collegues. From January to December, every two weeks, on friday at 2:00 pm
Seminars Room, NICO
The main goal of the BraYn initiative is to organize a scientific conference involving different laboratories across Italy and Europe where young researchers, especially PhD students and junior postdocs, can share their knowledge, skills and ideas to establish new collaborations between different research groups.
