Gene targets of sulforaphane in head and neck squamous cell carcinoma.

Gene targets of sulforaphane in head and neck squamous cell carcinoma. Mol Med Rep. 2019 Oct 23;: Authors: Hu L, Li H, Lee ED, Grandis JR, Bauman JE, Johnson DE Abstract Patients who have undergone curative‑intent therapy for head and neck squamous cell carcinoma (HNSCC) exhibit a high rate of development of second primary tumors (SPTs), which are frequently lethal. A chemoprevention strategy that prevents SPTs would have a major impact on patient outcomes. Sulforaphane, a naturally‑occurring compound derived from cruciferous vegetables exhibits chemopreventive activity against HNSCC in a preclinical model. The effects of sulforaphane are considered to be mediated, in large part, through increased protein expression of the transcription factor nuclear factor erythroid 2‑related factor 2 (NRF2). Development of sulforaphane chemoprevention for HNSCC would benefit from the identification of robust biomarkers of sulforaphane activity in HNSCC cells and normal mucosal epithelial cells. The present study revealed that sulforaphane potently induces multiple oxidative stress‑associated genes at the RNA and protein levels, in HNSCC cells and Het‑1A cells, a non‑tumorigenic mucosal epithelial cell line. In the present analysis, HMOX1 and HSPA1A were identified as the most highly upregulated genes following sulforaphane treatment, suggesting their potential value as biomarkers to guide clinical trials. Sulforaphane induction of HMOX...
