Transcriptome profiling in Eid1-KO mice brain shows that Eid1 links cell proliferation in the brain

Area of Science:

• Neuroscience
• Molecular Biology
• Genetics

Background:

• Eid1 protein family regulates differentiation, transcription, and acetyltransferase activity.
• Eid1's role in neurological disorders is suggested, but its brain function remains unclear.
• Understanding Eid1's function is crucial for neurological disorder research.

Purpose of the Study:

• To investigate the function of Eid1 in the mouse brain.
• To identify genes regulated by Eid1 using transcriptomic analysis.
• To elucidate Eid1's role in neural progenitor cell proliferation.

Main Methods:

• Generated Eid1-knockout (Eid1-KO) mice.
• Performed RNA sequencing on Eid1-KO mouse brains.
• Utilized qRT-PCR, protein-protein interaction analysis, neurosphere assays, CCK-8, and immunofluorescence assays.

Main Results:

• Identified 2531 differentially expressed genes in Eid1-KO mouse brains.
• Protein-protein interaction analysis implicated 'regulation of cell proliferation' as a key Eid1 function.
• Eid1-KO neural progenitor cells exhibited significantly reduced proliferation and neurosphere formation.

Conclusions:

• Eid1 plays a critical role in regulating neural progenitor cell proliferation in the brain.
• This study provides the first comprehensive Eid1-knockout brain transcriptome.
• The findings lay the groundwork for future research into Eid1's neurological functions.
