Additionally, while the expression level of ODF2L highly correlated with AZD1775 sensitivity in the parental ovarian cancer cells (Supplemental Figure 1B), we also observed a consistent and substantial increase in ODF2L expression in a panel of 4 AZD1775-resistant ovarian cell lines derived from the paired parental cell lines (Figure 1G). Here, ODF2L is linked to ovarian carcinoma.
