WebGraphic Abstract HIF1A is involved in Retinoic Acid (RA) induced dierentiation in SH-SY5Y neuroblastoma cells. siRNA HIF1A gene silencing leads to a weaker response to RA, demonstrated by changes in the neuro-like phenotype and diminished expression of dierentiation markers. WebIt is demonstrated that upregulation of HIF-1 α in NB promotes proliferation, migration and invasiveness via SHH signaling and the pro-migration and proliferative effects of Hif-1α could be reversed by disrupting SHH signalling. The aim of this study was to investigate the effects of hypoxia-inducible factor-1α (HIF-1α) on the proliferation, migration and …
