Expression data comparing the effect of IKK2 KO on a KRAS mouse model. Mus musculus

Given that the NF-κB pathway plays an important role in tumor development and that IKK2 is the seminal kinase responsible for NF-κB pathway activation, we were particularly interested in exploring the therapeutic potential of IKK2 inhibition in non-small cell lung cancers. We crossed IKK2fl/fl and KrasG12D mice so that we could simultaneously activate KrasG12D to initiate tumor formation and inactivate IKK2, upon transduction by Cre lentiviral vectors. Overall design: RNA isolated from finely dissected tumor nodules and tumor cell lines (4A3 and1D3) was applied to microarray analysis using Affymetrix Mouse Gene 1.0 STArrays according to the manufacturer’s instructions.
