The integrity of the monolayer formed by the cells was violated by scratching and the rate of its filling with tumor cells was monitored in the absence (control) and presence of Pulmozyme® at concentrations of (0.1–0.5) × 103 U/mL or DNase I at concentrations of (0.1–1.5) × 103 U/mL (Figure 1C–F). The gene discussed is DNASE1; the disease is neoplasm.
