Figure 2From: Over-expression of lysophosphatidic acid receptor-2 in human invasive ductal carcinomaRelative expression level of lysophosphatidic acid receptors' mRNA against β-actin in cancer tissue and normal mammary gland tissue, evaluated using real-time RT-PCR: (a) Lysophosphatidic acid receptor 1 (LPA1), (b) LPA2 and (c) LPA3. Y axis indicates the cDNA copies for lysophosphatidic acid receptors divided by that of β-actin in each case. *P < 0.05.Back to article page
