In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Context: It is unknown whether hypoxia regulates aurora kinase A (AURKA), a serine/threonine kinase, in neuroblastoma to stimulate cell growth or migration. We sought to determine whether AURKA mediates hypoxia-induced regulation of neuroblastoma tumorigenicity.', 'Human neuroblastoma BE(2)-C cells were treated with CoCl2, a chemical hypoxia mimetic, and MLN8237, a pharmalogical inhibitor of AURKA, to assess cell viability, colony formation and transwell migration. Focal adhesion kinase (FAK) expression was analyzed after silencing of AURKA under normoxic vs. hypoxic conditions.', 'Hypoxia up-regulated expression of AURKA mRNA and protein. CoCl2 stimulated cell proliferation and migration, while inhibiting colony formation. MLN8237 reduced colony formation and cell migration. Silencing of AURKA reduced expression of FAK and pFAK under normoxia and hypoxia.\Question: Does targeting aurora kinase A inhibit hypoxia-mediated neuroblastoma cell tumorigenesis?
Hypoxia positively regulates AURKA expression. Hypoxia-induced stimulation of colony formation and migration is, in part, mediated by AURKA. These findings establish that AURKA is a critical regulator of hypoxia-mediated tumor progression in neuroblastoma.
