Neurogenins are a family of bHLH transcription factors involved in specifying neuronal differentiation. In neural crest cells, the neurogenin family is essential for neurogenesis in the developing dorsal root ganglia and development of the sensory lineage.
What does neurogenin do?
Neurogenins are upstream activators of another bHLH gene, NeuroD, which promotes the withdrawal of precursors from the cell cycle and their differentiation into neurons (Lee et al., 1995).
What is Ngn1?
Ngn1 is a component of the bHLH factor code regulating cell type specification in the cerebellar cortex. Ngn1, as well as promoting neurogenesis, maintains an uncommitted progenitor cell population through Notch-mediated lateral inhibition, and Math1 irreversibly commits these progenitors to a hair-cell fate.
What do hes genes do?
Hes genes code nuclear proteins that suppress transcription. This protein belongs to the basic helix-loop-helix (bHLH) family of transcription factors. As a member of the bHLH family, it is a transcriptional repressor that influences cell proliferation and differentiation in embryogenesis.
What is PDX1 and Mafa?
Pancreas/duodenum homeobox protein 1 (PDX1), Neurogenin-3 (NEUROG3), and V-maf musculoaponeurotic fibrosarcoma oncogene homolog A (MAFA) are transcription factors critical for beta cell development and maturation. PDX1 is essential for the development of pancreatic exocrine and endocrine cells including beta cells.
What are NGN2 cells?
Description: Neurogenin (Ngn) 2 is a basic helix-loop-helix (bHLH) transcription factor that promotes direct differentiation of pluripotent stem cells to functional excitatory neurons. AAVS1 (also known as PPP1R12C) locus supports robust and sustained transgene expression.
What is Notch gene?
The NOTCH1 gene provides instructions for making a protein called Notch1, a member of the Notch family of receptors. Receptor proteins have specific sites into which certain other proteins, called ligands, fit like keys into locks.
What type of protein is encoded by the HES7 gene?
transcription factor
The HES7 protein is a transcription factor that functions as a transcriptional repressor. It is involved in somitogenesis, an important cycle in vertebrate development. Somitogenesis involves the early segmentation of vertebrates. HES7 is involved in segmenting the presomitic mesoderm into somites.
How do you activate neurogenesis?
Aerobic activities such as running, cycling, swimming, and even sex, are effective ways of boosting neurogenesis. The aim is getting the heart pumping for more than 20 minutes at a time, and on a regular basis. In this state levels of several growth hormones are elevated in the brain.
