Differential transcription of genes encoding HSPGs. (A,B) Relative transcript abundance of mRNAs for HSPGs. Relative abundance for healthy tissues (gray bars) and tumors (black bars) are plotted on a log scale for each gene assayed and the spreads represent the standard deviations. (A) Non-metastatic IDCs. (B) Metastatic IDCs. (C) Relative expression ratio of genes that show statistically significant differences in expression in non-metastatic (●) or metastatic (■) IDCs. Values on the Y axis are represented on a logarithmic scale.
