Gong Yang et al found that NF‐κB affects the development of ovarian cancer by regulating MAPK signalling pathways and apoptosis.49 In low‐grade serous ovarian cancer, NF‐κB can activate proapoptotic signals and act as a tumour suppressor.50 Thus, NF‐κB plays an important role in the development and progression of ovarian cancer. The gene discussed is NFKB1; the disease is ovarian cancer.
