Results: The NPY Y5 receptor Antagonist Molecular Weight overexpression of NCX1 induced neuronal differentiation through Akt as well as NGF exposure. NCX1 knockdown prevented NGF-induced neurite outgrowth. Conclusion: NCX1 participates in neuronal differentiation by ionic regulation and Akt phosphorylation. Significance: Learning how NCX1 participates in neurite outgrowth will boost the expertise of neuronal differentiation. NGF induces neuronal differentiation by modulating [Ca2 ]i. Having said that, the function with the 3 isoforms of your main Ca2 -extruding system, the Na /Ca2 exchanger (NCX), in NGF-induced differentiation remains unexplored. We investigated irrespective of whether NCX1, NCX2, and NCX3 isoforms could play a relevant function in neuronal differentiation by means of the modulation of [Ca2 ]i as well as the Akt pathway. NGF caused progressive neurite elongation; a important raise in the well-known marker of development cones, GAP-43; and an enhancement of endoplasmic reticulum (ER) Ca2 content and of Akt phosphorylation through an early activation of ERK1/2. Interestingly, through NGF-induced differentiation, the NCX1 protein level increased, NCX3 decreased, and NCX2 remained unaffected. In the very same time, NCX total activity increased. Furthermore, NCX1 colocalized and coimmunoprecipitated with GAP-43, and NCX1 silencing prevented NGF-induced effects on GAP-43 expression, Akt phosphorylation, and neurite outgrowth. However, the overexpression of its neuronal splicing isoform, NCX1.4, even within the absence of NGF, induced an increase in Akt phosphorylation and GAP-43 protein expression.
