A significant increase in gamma-glutamylcysteine synthetase activity and GST activity toward 4-hydroxynonenal and acrolein, which are preferred substrates of GST8-8, was seen as early as 3 days following AA treatment.

19651797 Zhang H, Forman HJ: Signaling pathways involved in phase II gene induction by alpha, beta-unsaturated aldehydes. Toxicol Ind Health. 2009 May-Jun;25(4-5):269-78.

Two electrophiles, 4-hydroxynonenal (HNE) and acrolein, induced the expression of phase II genes (GCLC, GCLM, NQO1, NQO2, HO-1, and GSTM-1).

19633057 Kelleher MO, McMahon M, Eggleston IM, Dixon MJ, Taguchi K, Yamamoto M, Hayes JD: 1-Cyano-2,3-epithiopropane is a novel plant-derived chemopreventive agent which induces cytoprotective genes that afford resistance against the genotoxic alpha,beta-unsaturated aldehyde acrolein. Carcinogenesis. 2009 Oct;30(10):1754-62. Epub 2009 Jul 24.

In rat liver RL-34 epithelial cells, 1-cyano-2,3-epithiopropane (CETP), 1-cyano-3,4-epithiobutane (CETB) and 1-cyano-4,5-epithiopentane (CETPent) were shown to induce cytoprotective enzymes including NAD (P) H:quinone oxidoreductase 1 (NQO1), glutathione (GSH) S-transferase A3 and the glutamate-cysteine ligase modifier subunit; CETP was more potent in this regard than were either CETB or CETPent, with 50 microM CETP eliciting a remarkable approximately 10-fold induction of NQO1.

12084617 Tirumalai R, Rajesh Kumar T, Mai KH, Biswal S: Acrolein causes transcriptional induction of phase II genes by activation of Nrf2 in human lung type II epithelial (A549) cells. Toxicol Lett. 2002 Jun 7;132(1):27-36.

Exposure of human type II lung epithelial (A549) cells to non-lethal dose of acrolein (150 fmol/cell for 1 h) depletes 80% of intracellular glutathione and increases the transcription of gamma-glutamylcysteine synthetase (gamma-GCS) at 6-12 h post-treatment, which helps in replenishing the glutathione to normal level.

Treatment of A10 cells with D3T also led to induction of gamma-glutamylcysteine synthetase, the key enzyme involved in GSH biosynthesis.
