ΔHER4 mRNA expression for each patient.

<p>Waterfall plot depicting the difference in total HER4 mRNA expression between the tumor tissue and the normal tissue for each patient (ΔHER4). The difference is calculated as the tumor tissue expression minus the normal tissue expression, and hence, a negative value represents a downregulation in the tumor tissue compared to the normal tissue. The tumor localization of the individual patients is depicted in the figure.
