However, the astrocytoma tissue mainly localized KMO and GFAP in the same cells; furthermore, on some astrocytoma slides, KMO immunofluorescence was found unrelated to GFAP marking, suggesting a contribution to KMO expression in tumor-infiltrated cells (Figure 4, lines 3–10). This evidence concerns the gene KMO and astrocytoma (excluding glioblastoma).
