abstract = {In mammals, specific brain regions such as the dentate
gyrus (DG) of the hippocampus and the subventricular zone
(SVZ) of the lateral ventricles harbor adult neural
stem/progenitor cells (ANSPCs) that give rise to new neurons
and contribute to structural and functional brain
plasticity. In contrast, other vertebrates such as
salamanders and zebrafish exhibit a widely distributed
neurogenic niches throughout the brain, suggesting a greater
neurogenic capacity in adulthood. However, the mechanisms
underlying this divergence in neurogenic potential among
vertebrates remain elusive. To address this, we examined the
expression dynamics of a critical epigenetic regulator for
the long-term maintenance of murine ANSPCs, lamin B1, during
adult neurogenesis across the vertebrate spectrum.Lamin B1
expression patterns during adult neurogenesis are conserved
among mammals including mouse, naked mole-rat, and ferret.
However, these patterns differ between mammals and
anamniotes. In mammals, neural stem cells and neuroblasts
exhibited higher lamin B1 levels, and differentiated neurons
possessed lower lamin B1 levels. On the other hand,
anamniotes showed the opposite patterns of lamin B1
expression, with higher levels in neurons compared to stem
cells.Our study shows that the lamin B1 expression pattern
during adult neurogenesis differs between species, and that
changes in lamin B1 protein sequence may contribute to the
differences in lamin B1 expression patterns. This study
highlights potential differences in cell-autonomous
epigenetic regulation in the maintenance of ANSPC pools in
the adult brain among species.},
