What's a GeneRIF?

results indicated that Brn4 promoted the neuronal differentiation of neural stem cells via inhibition of CtBP2 and is a potential tool for generating neurons in cell replacement therapy of neurodegenerative diseases and brain injury
Title: Brn4 promotes the differentiation of radial glial cells into neurons by inhibiting CtBP2.
The co-transduction of Nurr1 and Brn4 genes induces cell differentiation of neural stem cells
Title: The co-transduction of Nurr1 and Brn4 genes induces the differentiation of neural stem cells into dopaminergic neurons.
Brn-4 expression is required both for neuronal differentiation of NSCs and maturation of newborn neurons, and that there may be some regulatory factors in deafferented hippocampus that can regulate Brn-4 expression in neuronal progenitors.
Title: The role of Brn-4 in the regulation of neural stem cell differentiation into neurons.
study showed after fimbria-fornix lesion, Brn-4 in deafferented hippocampus was upregulated & might play a role in inducing local progenitors to differentiate into neurons, which may compensate for loss of cholinergic afferent fibers or other dysfunctions
Title: Brn-4 is upregulated in the deafferented hippocampus and promotes neuronal differentiation of neural progenitors in vitro.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
