A novel role for vaping in mitochondrial gene dysregulation and inflammation fundamental to disease development
Abstract We constructed and analyzed the whole transcriptome in leukocytes of healthy adult vapers (with/without a history of smoking), ‘exclusive’ cigarette smokers, and controls (non-users of any tobacco products). Furthermore, we performed single-gene validation of expression data, and biochemica...
