To identify relationship between expression of ANXA1 and chemo‐resistance in ovarian cancer, we examined the difference in the expression of ANXA1 in SKOV3 and SKOV3/DDP cell lines, and the PCR and Western blotting results showed that the expression of ANXA1 in SKOV3/DDP was increased (Figure 1A–B). The gene discussed is ANXA1; the disease is ovarian cancer.
