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.

Reduced risk tobacco products and methods of making same

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.

Global gene expression analysis of human bronchial epithelial cells exposed to cigarette smoke, smoke condensates, or components thereof

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.

Approaches to identify less harmful tobacco and tobacco products

This invention provides methods for screening a modulating agent which when combined with antitumor therapeutic agent increases apoptosis in tumor cells. This invention also provides methods for screening antitumor therapeutic agents suitable for combination therapy with a protein kinase C inhibitors capable of potentiating apoptosis in tumor cells. This invention further provides different combination therapies comprising the specific protein kinase C inhibitors and the antitumor therapeutic agents.

Combinations of PKC inhibitors and therapeutic agents for treating cancers

This invention provides methods for screening protein kinase C inhibitors capable of potentiating apoptosis in tumor cells. This invention also provides methods for screening antitumor therapeutic agents suitable for combination therapy with a protein kinase C inhibitors capable of potentiating apoptosis in tumor cells. This invention further provides different combination therapies comprising the specific protein kinase C inhibitors and the antitumor therapeutic agents.

Combinations of PKC inhibitors and therapaeutic agents for treating

This invention provides a method of detecting sensitivity to alpha-interferon therapy which comprises contacting a sample with a monoclonal antibody under conditions so as to form an antibody-antigen complex, detecting the complex so formed, and thereby detecting sensitivity to alpha-interferon.

Method to detect sensitivity to alpha-interferon therapy

This invention relates to monoclonal antibodies recognizing the gp130 antigen of human cells. Monoclonal antibodies which recognize distinct determinants on this antigen and methods of detecting the determinants by immunoassay with the monoclonal antibodies which recognize them are disclosed. The monoclonal antibodies are useful in the detection of the gp130 antigen and human cells including melanoma which contain this antigen.

Monoclonal antibodies to melanoma cells

Monoclonal antibodies were discovered which recognize differentiation antigens on melanocytes and melanoma cells at various stages of differentiation. A system of classification based on these antigens is proposed and their use in the diagnosis and treatment of melanoma is given.

Monoclonal antibodies against melanocytes

Method of forming an antibody producing hybridoma cell line by fusing a myeloma cell line with splenocytes derived from BALB/c mice immunized with human astrocytoma tumor cells, the hybridoma cell line formed, and the monoclonal antibodies generated by said hybridoma cell line. A method of phenotyping astrocytoma tumor cells comprising determining the reaction of said cells to various monoclonal antibodies to astrocytoma tumor cells is also provided.
