BCL7A regulates SWI/SNF/BAF complexes, impacting neural progenitor cell (NPC) differentiation and mitochondrial function. Its absence impairs neurogenesis and cognitive abilities, highlighting its role in neuronal development and brain function.
Area of Science:
- Chromatin biology
- Neuroscience
- Cellular metabolism
Background:
- Mammalian SWI/SNF/BAF chromatin remodeling complexes are crucial for cell lineage determination.
- While their role in neural progenitor cell (NPC) proliferation and differentiation is known, transcriptional regulators of neurogenesis versus gliogenesis remain unclear.
Purpose of the Study:
- To investigate the role of BCL7A as a modulator of SWI/SNF/BAF complexes in NPC differentiation.
- To understand how BCL7A influences Notch/Wnt signaling, mitochondrial bioenergetics, and neurogenesis.
Main Methods:
- Assessed BCL7A's effect on SWI/SNF/BAF complex occupancy by BRG1.
- Utilized pharmacological interventions (Wnt signaling agonists, pioglitazone) in NPCs.
- Generated conditional BCL7A knockout mice to study in vivo effects on neuronal plasticity and cognition.
Main Results:
- BCL7A modulates SWI/SNF/BAF complex activity and is essential for regulating Notch/Wnt signaling and mitochondrial bioenergetics in NPCs.
- Wnt signaling stimulation or pioglitazone treatment partially restored mitochondrial respiration and neurogenesis in BCL7A-deficient NPCs.
- BCL7A is required for neuronal plasticity, supporting cognitive and behavioral performance in mice.
Conclusions:
- BCL7A-containing SWI/SNF/BAF complexes are critical for mitochondria-driven NPC commitment.
- These findings elucidate the link between metabolism, neuronal development, and cognitive flexibility, mediated by BCL7A.

Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
