To further investigate whether this AMPK/TAK1/NF-κB signaling axis is required for promoting metastatic seeding of ovarian cancer cells in omental tissues, we established an ex vivo murine omental system by culturing omenta from 6- to 8-week-old SCID female mice (to exclude immune cells)5. The gene discussed is NFKB1; the disease is ovarian carcinoma.
