(A) Affymetrix mRNA expression analysis (probe sets: KALRN, 230596, 206078, 227750, 232717; TIAM1, 213135; TRIO, 209011, 209012, 208178, and 209013) in two series of NB tumor samples (red) and series of various other tumor types (blue). (B) Expression of KALRN, TIAM1, and TRIO in NB cell lines (red) and series of different cancer cell lines (black). (C) Graphs showing correlation of expression of DCX (left) or SOX11 (right) and KALRN, TIAM1, or TRIO in primary NB (gse49710). (D) WB analysis of kalirin expression with kalirin-SP, TRIO, TIAM1, kalirin-STYV, and anti-kalirin-PH-2 in NB cell lines and primary tumors. Asterisks indicate previously annotated isoforms.
