  • To meet specific cellular demands of different cell types over time cellular biogenesis is definitely mediated through the dynamic mitochondrial fusion and fission. (biopaqc.com)
  • Mind tumor initiating cells (BTICs) coopt the neuronal high affinity GLUT3 blood sugar transporter to withstand metabolic tension. (biopaqc.com)
  • While all tumor cells display dysregulation of metabolic pathways the differential growth patterns of BTICs suggest that these tumor subpopulations have metabolic features that distinguish them from your tumor bulk17-20. (biopaqc.com)
  • To establish protocols for the safe and efficient differentiation of healthy cells for therapies, we must develop a better understanding of the dynamic continuum of metabolic states that span pluripotency and differentiation, and how to influence them. (conditionmed.org)
  • To gain new insights into pathogenesis of specific neurological and neurodevelopmental disorders, such as autism, pluripotent stem cells are derived by reprogramming of differentiated, mature cells of affected patients. (yale.edu)
  • These findings lead to a model in which both CR and GABAergic cell-derived Reelin cooperate to build the inside-out order of corticogenesis, which might provide a better understanding of the mechanisms involved in the pathogenesis of neuropsychiatric disorders linked to abnormal migration and Reelin deficits.

  • Mutations in this gene may be associated with X-linked disorders with primary neuronal degeneration such as Rett syndrome. (thermofisher.com)
