The current single-cell RNA sequencing experiment can be effectively integrated with prior data35–37 obtained from the same lung cancer cell lines, specifically A549 (Fig. 4A) and PC9 (Fig. 4B), as well as with other cell lines characterized by the expression of identical cancer driver genes (Fig. 4A), such as EGFR (H1975, HCC827) and KRAS (H838). The gene discussed is KRAS; the disease is lung carcinoma.
