Constitutive NF-κB Activation in Cancer Models

October 2, 2026 by Yao Lin

Blue-toned stylized animal cell with visible internal membranes and mitochondria, a large glowing nucleus, and a gold bead-like molecular chain entering from the upper left toward the nucleus.

Constitutive NF-κB activation is an experimental conclusion, not a synonym for one positive assay. This guide explains the evidence needed to demonstrate persistent baseline signaling and pathway dependence in cancer models.
