Graphs demonstrating moderate and strong levels of secreted frizzled-related protein 3 expression in different grades of astrocytic brain tumor. (A) Nuclear and (B) cytoplasmic expression. (A) High grade tumors (A III and G IV) exhibited significantly lower mean values of both moderate and strong nuclear expression, as compared with the moderate and strong values of low grade tumors (A I and A II) (^*P<0.05). (B) Mean values of moderate and strong cytoplasmic expression for high grade tumors were significantly higher than the mean values of low grade tumors (^*P<0.05). A I, pilocytic astrocytoma; A II, diffuse astrocytoma; A III, anaplastic astrocytoma; G IV, glioblastoma.
