highly significantp<2.68E-74
Interestingly, nearly all of the IPR genes described above are also induced following bortezomib treatment ( Fig 6E ), an overlap that is highly significant (representation factor (rf) = 10.8; p<2.68E-74; rf is the ratio of actual overlap to expected overlap where rf>1 indicates overrepresentation and rf<1 indicates underrepresentation; see Materials and Methods ).
