For this analysis, we selected three cell lines, EFO27 and PEO4 among the cancer cell lines and the immortalized primary ovarian cell line, where we analyzed the expression levels of ALDH1A1 and CD44 after LACTB induction at day 0, 3, 6, and 12 (Figs 4A and S3A). The gene discussed is ALDH1A1; the disease is cancer.
