Next, we correlated NAMPT and PARP1 transcript levels with biomarkers of epidermal hyperplasia (K16, Ki67 and PCNA) (Figure 4A), type 2 inflammation (CCL17, CCL18) and other inflammatory biomarkers (MMP9 and CA2) (Figure 4B) that have already been studied in AL and ANL samples [14,15]. The gene discussed is PCNA; the disease is axial length measurement.
