Control YKG-1 subline	Control YKG-1 subline	Homo sapiens	9606	control subline (infected of the retrovirus expressing short hairpin RNA containing scrambled sequence)	YKG-1	Human glioblastoma	gene_knock_in	SAMD00160562	Control YKG-1 subline	The knockdown vector was constructed by using a shRNA expression retroviral vector pSINsi-hU6 (TAKARA Bio, Shiga, Japan). The most efficient target sequence for RNA interference was selected among six. U251 cells were exposed to the virus pools produced by transfection of the vector into Amphopack293 packaging cells. The transfected cells were subcultured at an appropriate density in fresh DMEM containing 0.5 mg/ml. The G418-resistant cell pools were readily established within 2 weeks.
