Figure Lengend Snippet: ( A ) MRNA microarray validation with qRT-PCR analysis in grouped RISC-IP U-87 astrocytoma and primary astrocytes samples. Grouped RISC-IP data were compared to the grouped global mRNA from U-87 astrocytoma and primary astrocytes samples. Eight mRNAs were selected from the grouped mRNA microarray dataset and examined by qRT-PCR. Fold change from the mRNA microarray are given by log2 values (left y-axis, light grey bars). Fold change from the qRT-PCR was determined using the 2 -ΔΔCt method and all mRNA expression values were normalized to the beta-actin endogenous control (right y-axis, dark grey bars). Error bars represent the standard deviation of the mean (SD). Importantly, the fold change (y-axis) cannot be directly compared between assays due to differences in calculation methods, but the general trend of up-regulation and down-regulation can be compared. ( B ) MRNAs in RISC compared to the global cellular milieu in U-87 astrocytoma cells. MRNA expression in U-87 astrocytoma cells were normalized to primary astrocytes mRNA expression. All mRNAs had a fold change >2.5 and were significantly expressed (p<0.01). Green and red arrows indicate decreased and increased levels respectively.

Figure Lengend Snippet: Bar charts display the relative number (-log(p-value)) of mRNAs with a fold change >2.5 and were considered significant (p<0.01). RISC-IP mRNA were indicated with dark blue bars and the global mRNA were indicated with light blue bars. The threshold (yellow lines) were set at p<0.01 and were calculated using Fischer's exact p-value test using IPA software.

Figure Lengend Snippet: Nine miRNAs (A) and eight mRNAs (B) selected from micorarry data were detected by qRT-PCR. Fold changes from the microarray were given by log2 values (right y-axis). Fold changes from the qRT-PCR were determined using the 2 −ΔΔCt method and normalized to the endogenous control GAPDH or U6 (left y-axis). Error bars represent the standard deviation of the mean (SD). Importantly, the fold changes (y-axis) cannot be directly compared between assays due to differences in calculation methods, but the general trend of upregulation and downregulation can be compared.
