TUBB2B and neuroblastoma: Our RT-PCR analysis showed that transfection of BE(2)-C and CHP134 neuroblastoma cells, which express high levels of lncNB1 (Fig. 1d), with lncNB1 siRNAs, siRNA-1, or siRNA-2, did not have an effect on the expression of TUBB2A or TUBB2B (Supplementary Fig. 2a, b), the neighboring protein-coding genes of lncNB1.
