Abstract: Embodiments provided herein concern tobacco and tobacco products having a reduced amount of a harmful compound. More specifically, several embodiments concern approaches to modify the expression of a gene that is involved in the production of a harmful compound in tobacco, tobacco products made using these approaches and methods of determining whether the removal of said compounds using said approaches yields a tobacco and/or a tobacco product that has a reduced potential to contribute to a tobacco-related disease.

Abstract: Aspects of the invention concern methods for detecting, identifying and evaluating tobacco and tobacco products to determine the potential that these compositions have to contribute to a tobacco-related disease. It is based, at least in part; on the discovery that exposure of pulmonary cells to smoke or smoke condensate obtained from tobacco or tobacco products induces double stranded breaks in cellular DNA, which were efficiently detected using assays that measure the presence, absence, or amount of phosphorylation of the histone, H2AX.

Abstract: Reduced risk tobacco-related products and methods of use. These tobacco-related products (e.g., cigarettes or filters) are designed to reduce the biological insult, for example, DSBs, cell death or perturbation of RNA transcriptome or proteome as compared to the amount of biological insult induced by another cigarette, such as a conventional or reference cigarette (e.g., 2R4F), in human cells, and to provide a reduced risk cigarette that meets a cigarette smoker's sensory/perception needs.

Abstract: Aspects of the present invention concern the identification of several methods to analyze the genes that are modulated in normal human bronchial epithelial (NHBE) cells after exposure to cigarette smoke condensates (CSC) or cigarette smoke (CS). Embodiments described herein include methods to identify a gene that is modulated in response to exposure to CSC or CS, methods to identify tobacco products that have a reduced potential to contribute to tobacco-related disease, methods to make tobacco products that have a reduced potential to contribute to a tobacco-related disease, methods to identify a subject's predilection to acquire a tobacco related disease, the use of particular genes as biomarkers for tobacco-related disease, and patterns of gene expression or genetic signatures that are unique to each particular tobacco product.
