We used microarrays to provide new insights into the carcinogenic effects of tobacco smoke and offer insights that may prove useful in developing preventive strategies. Overall design: 40 never smokers (<100 cigarettes per lifetime) and 40 active smokers (≥ 15 pack year exposure) were recruited. Subjects were age- and gender-matched. Eligible subjects were healthy volunteers recruited from the community and the hospital. Subjects were excluded if they had gross evidence of oral inflammation a history of heavy alcohol consumption or recent use of nonsteroidal anti-inflammatory drugs or other anti-inflammatory medications. The study was approved by the Weill Cornell Medical College Institutional Review Board and the Clinical and Translational Research Center. All subjects provided written informed consent for participation. After topical anestesia 5-mm punch biopsies were obtained from grossly normal appearing buccal mucosa. One sample was excluded from the study based on a quality measure leaving 79 for analysis and deposited here.ENAGene Expression, human being, Transcriptome, Expression Signature, Transcriptome Profile, Gene Expression Profiles, Transcriptome Profiles., Expression Signatures, Profile, Gene Expression Signatures, Expression Profiles, Transcriptomes, Gene Expression Profile, Gene, Gene Expression Signature, Profiles, Signature, Expression Profile, man, Signatures, humanhuman being, human., man0.00.00.00.00.00falseHomo sapiensEffects of Cigarette Smoke on the Human Oral Mucosal Transcriptome2022-05-122014-02-11PRJNA120057GSE17913201792999606
