Project description:To identify the differential porfile of long non coding RNAs in neural stem cells exposed to sevoflurane compared with control gas(21% oxygen,5%CO2,),We employed the rat long non-coding RNA array as a discovery platform to identify genes with potential to regulate self-renewal capacity of rat neural stem cells exposed to sevoflurane.

Project description:Long noncoding RNAs (lncRNAs) have emerged as important components of gene regulatory network in embryonic stem cells (ESCs). However, the function and molecular mechanism of lncRNAs are still largely unknown. Here we identified Trincr1 (TRIM71 interacting long noncoding RNA 1) lncRNA that regulates the FGF/ERK signaling and self-renewal of ESCs. Trincr1 is exported by THOC complex to cytoplasm where it binds and represses TRIM71, leading to the downregulation of SHCBP1 protein. Knocking out Trincr1 leads to the upregulation of phosphorylated ERK and ERK pathway target genes and the decrease of ESC self-renewal, while knocking down Trim71 completely rescues the defects of Trincr1 knockout. Furthermore, ectopic expression of Trincr1 represses FGF/ERK signaling and the self-renewal of neural progenitor cells. Together, this study reveals more regulators in FGF/ERK signaling pathway and highlights lncRNA as an important player in cell signaling network to coordinate cell fate specification.

Project description:Bmi1 is a component of polycomb repressive complex 1 and its role in the inheritance of the stemness of adult somatic stem cells has been well characterized. Bmi1 maintains the self-renewal capacity of adult stem cells, at least partially, by repressing the Ink4a/Arf locus that encodes a cyclin-dependent kinase inhibitor, p16Ink4a, and a tumor suppressor, p19Arf 14. Deletion of both Ink4a and Arf in Bmi1-deficient mice substantially restored the defective self-renewal capacity of HSCs and neural stem cells. Purified KSL cells from BM of wild-type, Bmi1-/-, Ink4a-/-Arf-/-, and Bmi1-/- Ink4a-/-Arf-/- mice were subjected to RNA extraction and hybridization on Affymetrix microarrays.

Project description:TMF1-regulated nuclear protein 1 (Trnp1) has been shown to exert potent roles in neural development affecting neural stem cell self-renewal and brain folding, but its molecular function in the nucleus is still unknown. Here we show that Trnp1 is a low complexity protein with the capacity to phase separate. Trnp1 interacts with factors located in several nuclear membrane-less organelles, the nucleolus, nuclear speckles and condensed chromatin. Importantly, Trnp1 co-regulates the architecture and function of these nuclear compartments in vitro and in the developing brain in vivo. Deletion of a highly conserved region in the N-terminal intrinsic disordered region abolishes the capacity of Trnp1 to regulate nucleolar size and dynamics, proliferation and M-phase length, decreases the capacity to phase separate and abrogates most of Trnp1 protein interactions. Thus, we identified Trnp1 as a novel regulator of several nuclear membrane-less compartments, a function important to maintain cells in a self-renewing proliferative state.
