Gene expression profiling of MDA-MB-468 cells following p53-R273H mutant knock-down. Homo sapiens

A total of 58 genes were up-regulated (> 1.5 fold-change) while 117 genes were down-regulated Overall design: Microarray experiments were performed in duplicate as follows: MDA-MB-468 cells were transduced with lentiviral shRNA targeting endogenous p53-R273H mutant (p53si-1)or a non-targeting shRNA (NS). Total RNA from cells was extracted using Qiagen RNA isolation kit (Qiagen, Valencia, CA, USA) according to the manufacturers’ protocol. RNA purity was examined by spectrophotometric determination at 260/280 nm. The microarray hybridizations were carried out using the Affymetrix Human Gene 1.0 ST arrays.
