CGA and neuroblastoma: Furthermore, although atRA treatment inhibited in vitro neuroblastoma proliferation in the nonsense control neuroblastoma cells (nonsense, vehicle versus atRA, 1.0±0.02 versus 0.32±0.001, P<0.005, Fig. 2F, right panel), atRA treatment did not inhibit but increased proliferation in the SH-SY5Y shRNA CgA cells (shRNA CgA, vehicle versus atRA, 0.24±0.001 versus 0.45±0.01, P<0.01, Fig. 2F, right panel), further emphasizing the difference in cell phenotype induced by CgA knockdown.
