1 Normal Anaplastic astrocytoma Glioblastoma Figure S1; Soumya et al., 2009 Malignant astrocytoma Figure S1. One-way hierarchical clustering of significance analysis of microarray identified grade specific miRNAs that differentiate malignant astrocytoma from normal brain samples. Normalized, log 2-transformed expression ratios of significance analysis of microarrays identified differentially regulated miRNAs were subjected to one-way hierarchical clustering using TMEV software to see if gene set can cluster samples of different grade separately. A dual color code was used with red and green indicating up- and down-regulation, respectively, in the particular astrocytoma sample compared to normal brain tissue. There were 55 miRNAs found to be up regulated and 29 miRNAs down regulated in malignant astrocytomas in comparison to normal brain samples at a false discovery rate (FDR) of 0.0%.

A and B) One-way hierarchical clustering of significance analysis of microarrays identified grade specific miRNAs that differentiate anaplastic astrocytoma and secondary glioblastoma (A) and anaplastic astrocytoma from primary glioblastoma (B). A dual color code was used with red and green indicating up- and down-regulation, respectively. Anaplastic astrocytoma
