Source name |
HeLa cells transduced LKO control lentivirus.

Characteristics |
cell line: HeLa

Treatment protocol |
Lentiviral pLKO-shRNAs were obtained from Sigma-Aldrich. The tracking numbers of the most effective shRNAs are TRCN0000019894 (YY1), TRCN0000016494 (YY2). To replace the puromycin-resistance gene in pLKO plasmids by neomycin-resistance for combined knockdown, an 827 bp fragment containing neoR gene was amplified from plasmid pCNH with primers 5'-TCA GGA TCC AGG ATC GTT TCG CAT GAT TGA AC-3' and 5'-TCA GGT ACC GAT GCA TGA GTC CCG CTC AGA AGA ACT CG-3', digested by Kpn I and BamH I, and ligated to Kpn I/BamH I-treated pLKO- shRNA plasmids. pLKO-shRNAs were packaged in 293T cells following the manufacturer’s standard protocol (Sigma-Aldrich). Spent medium of 293T cells was collected at 24-hour and 48-hour post-transfection, pooled, and cleared through a 0.45-micron syringe filter. To in-fect, HeLa cells were grown in 6-well culture plates in 2 ml medium and 0.5 ml of lenti-virus-containing medium was added. After 72 hours, cells were selected and maintained in medium containing 2 mg/ml of puromycin. To make combined shRNA transfectants, this process was repeated but selected using 500 mg/ml of Geneticin G418 for dual se-lections. Stable transfectants were split once a week and cells of less than fifteen pas-sages were used in all assays.

Growth protocol |
HeLa cells were cultured in Dulbecco’s modified Eagle’s medium (DMEM) supplemented with 10% fetal bovine serum, and maintained in 37°C incubators with 5% CO2.
