Fig. 4: IKKα expression and survival.

Expression of IKKα in the cytoplasm was not associated with CSS in the full cohort (a). High expression of cytoplasmic IKKα was associated with significantly worse cancer-specific survival in patients with right-sided tumours (b) but not in those with left-sided or rectal tumours (c, d). Punctate expression of IKKα was associated with CSS in the full cohort (e).
