Interestingly, analysis of NAV3 expression at single‐cell level, based on data from Darmanis et al. [23], implies that the decreased levels of NAV3 within the tumor areas are due to a low percentage of neoplastic cells expressing NAV3 (Figure 1E, left), rather than lower expression levels compared to other cell types (Figure 1E, right). This evidence concerns the gene NAV3 and neoplasm.
