Examination of p42.3 in brain gliomas. (A) and (B) p42.3 expression was confirmed in five glioblastoma multiforme (GBM) samples, one astrocytoma sample and one oligoastrocytoma (OA) [it is correct here as written, “astrocytoma” and “oligoastrocytoma”.] sample by RT-PCR. (C) p42.3 was not expressed in normal brain tissue. The PC3 cell line served as the positive control. (D) mRNA in situ hybridization analysis showed that p42.3 was significantly overexpressed in anaplastic OA (b) and GBM (c), but not in normal brain tissue (a).
