Hif 1a knockdown+ neuroblastoma
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 … WebRecruitment of HIF-1a and HIF-2a to common target genes is differentially regulated in neuroblastoma: HIF-2a promotes an aggressive phenotype Linda Holmquist …
