Abstract 1983: Altered regulation of CEBP transcription factor family in normal bronchial epithelial cells of subjects with lung cancer or COPD

Background: Antioxidant (AO), DNA repair (DNAR), and cell cycle control (CCC) genes play a role in protecting normal bronchial epithelial cells (NBEC) from damage, and sub-optimal function is associated with risk for COPD and lung cancer. CEBP transcription factors regulate key AO and DNA repair genes in NBEC. In this study, we investigated the association between CEBP transcription factor function and regulation of these gene pathways in NBEC of cancer (CA) and non-cancer (NC) COPD subjects. Methods: NBEC samples were obtained by bronchoscopy from 66 CA cases and 60 matched NC controls, and 30 NC COPD and 30 NC non-COPD controls defined by spirometry (FEV1 Citation Format: Jiyoun Yeo, Erin Crawford, Xiaolu Zhang, Albert Levin, James Willey.
