Notably, the proportion of CA12-expressing cancer cells within a patient exhibited a strong positive correlation with key components of the NF-κB signaling pathway — NFKB1 (r = 0.73, p < 0.0001), NFKB2 (r = 0.67, p < 0.0005), RELA (r = 0.64, p < 0.011), and RELB (r = 0.51, p < 0.0127) — in PDAC samples (Fig. 3G). The gene discussed is NFKB2; the disease is cancer.
