บทคัดย่อ/คำอธิบาย :

The adult glial progenitor cells were recently shown to be able to produce neurons in central nervous system (CNS) and to become multipotent in vitro. Although the fate decision of glial progenitors was studied extensively, the signals and factors which regulate the timing of neuronal differentiation still remain unknown. To elucidate the mechanisms underlying the neuronal differentiation from glial progenitors, we modified the gene expression profile in NG2+ glial progenitor cells using enhanced retroviral mutagen (ERM) technique followed by phenotype screening to identify possible gene(s) responsible for glial-neuronal cell fate determination. Among the identified molecules, we found the gene named non-metastatic cell 1 which encodes a nucleoside diphosphate kinase protein A (Nm23-M1 or NME1). So far, the Nm23 members have been shown to be involved in various molecular processes including tumor metastasis, cell proliferation, differentiation and cell fate determination. In the present study, we provide evidence suggesting the role of NME1 in glial-neuronal cell fate determination in vitro. We showed that NME1 is widely expressed in neuronal structures throughout adult mouse CNS. Our immunohistochemical results revealed that NME1 is strongly colocalized with NF200 through white matter of spinal cord and brain. Interestingly, NME1 overexpression in oligodendrocyte progenitor OLN-93 cells potently induced the acquisition of neuronal fate, while its silencing was shown to promote oligodendrocyte differentiation. Furthermore, we demonstrated that dual-functional role of NME1 is achieved through cAMP-dependent protein kinase (PKA). Our data therefore suggested that NME1 acts as a switcher or reprogramming factor which involves in oligodentrocyte versus neuron cell fate specification in vitro.
