Using the Finak Breast dataset from the ONCOMINE cancer microarray database (Finak et al., 2008), we determined that PARN was downregulated in invasive breast carcinoma compared to adjacent non-cancerous breast stroma (Fig. 1A), while gene expression of PLD2 was significantly upregulated in the same dataset (Fig. 1B). Here, PLD2 is linked to invasive breast carcinoma.
