Immunohistochemical staining for S6K2, hnRNPA1 and BCL-XL. TMA samples from lung (n = 204) (A) and breast cancer (n = 194) (B) patients were stained for S6K2, hnRNPA1 and BCL-XL. An increase in S6K2 staining correlates with concomitant increase in BCL-XL and decrease in cytoplasmic hnRNPA1 staining. Patients were grouped (X axis; group 1–4) according to their staining scores for S6K2 and correlation curves between the staining intensities for BCL-XL and cytoplasmic hnRNPA1 with groups 1–4 plotted. Correlation coefficients and P-values (ANOVA test) are shown. (C) Schematic illustration of how FGF-2 signalling regulates the shuttling of hnRNPA1 and the translation of BCL-XL and XIAP mRNAs.
