Lentivirus-mediated overexpression of GATA3 significantly increased the number of GFAP/SOX2 double positive astrocytes and expression of pro-neural factor ASCL1, but failed to induce neurogenesis, suggesting that GATA3 is required for enhancing the neurogenic potential of primary human astrocytes and is not sufficient to induce neurogenesis alone.

Using this stochastic model with a simulation program, we derived the equilibrium distribution of cell population and simulated the progression of the neurogenic cascade. (biomedcentral.com)
the neuroblast stage has the highest temporal variance within the cell types of the neurogenic cascade, while the apoptotic stage is short. (biomedcentral.com)

Histone H3K27 acetylation precedes active transcription during zebrafish zygotic genome activation as revealed by live-cell analysis. (janelia.org)

The phenomenon of neurogenesis in adult animals, which has therapeutic potential in treating neurodegenerative diseases, leads to several questions: What controls the pattern of connections formed by new cells? (pasteur.fr)

It comprises four pairs of sensory cells that are located dorsolaterally and ventrolaterally in the episphere of the trochophore. (biomedcentral.com)

In contrast to his claims that mammalian pheromones, including human pheromones, do not exist, we have demonstrated an effect on hormonal conditioning of behavioral affects in a series of presentations that began with (Kelahan et al. (rna-mediated.com)

Therefore, in this review, we avoid a lengthy repetition of the description of autophagy and cell death processes and focus on the death-promoting roles of autophagy and the intertwined connection between autophagy and apoptosis. (nature.com)
The sub G1 peaks, which signify necrosis/apoptosis, are greater in DCS taken care of 40AF cells compared with all the handle group. (cox2-inhibitors.com)

The studies highlighted in this review illustrate the potential importance of neurogenesis in reproductive function and will provide new insights for the significance of adult neurogenesis. (microrna.pro)
