title: Proteomic analysis of proteins associated with tt-DDE induced toxicity in BEAS-2B cells.
abstract: Trans, trans-2,4-decadienal (tt-DDE), a specific type of dienaldehyde, is abundant in heated oils or cooking oil fumes. Ingestion of heated oils and exposure to cooking oil fumes has been suggested to have a great health impact in a variety of organs, including the lungs. Previous studies have demonstrated that acute exposures to high doses of tt-DDE have induced oxidative stress, genotoxicity, and cytotoxicity in human lung cells. The objective in utilizing proteomic techniques of this study was to identify protein biomarkers associated with tt-DDE-induced oxidative stress and cytotoxicity in human bronchial epithelial cells BEAS-2B. Experimental results suggested that DJ-1 and cofilin proteins were protein biomarkers for tt-DDE-induced cytotoxicity and oxidative stress in lung cells. DJ-1 was especially an early biomarker for tt-DDE exposure.
