PLAUR and neuroblastoma: The effect of cisplatin (CDDP) treatment was examined using neuroblastoma Neuro2a cells, where uPAR expression was targeted either by CRISPR/Cas9n (Neuro2a-ΔuPAR, clones #3, #6, #30) or by shRNA (Neuro2a-shuPAR) to avoid the effects related to the individual features of the selected clones.
