Proposed effect of GSTA4-4 on 4-HNE and serum depletion in NF-κB signal transduction pathway. The solid arrow → indicate a positive effect or induction on the downstream pathway, the symbol ⊣ indicates suppressive effect. The central role of GSTA4-4 mediated through NF-κB pathway is by conjugation of 4-HNE, adapted from EMD Chemicals, Inc. website.
