摘要:
U2OS cells were transduced by a lentiviral vector carrying a Cdh1 shRNA and a puromycin resistance gene for selection. A vector carrying a GFP shRNA was used as control. The cells were stored in liquid N2 within 10 days after transduction in order to minimize the number of passages. Cells were thawed one week before the experiment, and grown in up to seven 175T flasks containing 6x106 cells each. For synchronization, 2.5mM thymidine was added to the medium for 21 hours. After removal of thymidine, cells were cultured with 100nM nocodazole for 18 hours. Cells that had entered mitosis were collected, washed in PBS for 3 times, and cultured in fresh media for another 6 hours. RNA was isolated and analysed by Gene expression analysis using the HG-U133plus 2.0 GeneChip array (Affymetrix, Santa Clara, CA, USA) according to the standard Affymetrix protocol using 5µg of total RNA
