CLDN9 primarily enhances cell migration by inducing cytoskeletal rearrangement and activating pathways, including MAPK and Tyk2/STAT3. Moreover, CLDN9 overexpression is associated with pseudopodia formation, glycolytic remodeling, and immune evasion. Conversely, CLDN6 is more strongly linked to cell invasiveness and matrix degradation, primarily through the induction of MMPs via the EGFR/mTOR and PI3K/AKT pathways. CLDN6 also plays a role in stemness and therapy resistance in specific cancers.
