Neuroblastoma is a tumor arising from pluripotent sympathoadrenal precursor cells
of neural cell origin. Neuroblastoma is one of the most aggressive childhood
tumors with highly invasive and metastatic potential. The increased expression of
urokinase and its receptor is often associated with a negative prognosis in
neuroblastoma patients. We have shown that targeting of the Plaur gene in mouse
neuroblastoma Neuro 2A cells by CRISPR/Cas9n results in ~60% decrease in cell
proliferation (p<0.05), reduction in the number of Ki-67 positive cells, caspase
3 activation and PARP-1 cleavage. Knockout of uPAR leads to downregulation of
mRNA encoding full-length TrkC receptor, which is involved in p38(MAPK) and Akt
signalling pathways. This finding provides a rationale to study a role of uPAR in
neuroblastoma progression, since uPAR could be considered a potential therapeutic
target in neuroblastoma treatment.
