Evaluation of AP-1 transcription factors in human Glioblastoma, astrocytoma and normal brain specimens. Expression of AP-1 family members was analyzed in situ by IFA. The specimens were evaluated in a blinded manner by 3 investigators and the results are shown as mean ± SD. Extent of immunostaining for each phenotype corresponds to ≤ 1+, negative; 2 + , positive; 3 + , strongly positive; 4 + , more strongly positive
