Receptor tyrosine kinases activate mitogen-activated protein (MAP) kinases through Ras, Raf-1, and MEK. Receptor tyrosine kinases can be transactivated by G protein-coupled receptors coupling to G(i) and G(q). The human G protein-coupled serotonin receptors 5-HT(4(b)) and 5-HT(7(a)) couple to G(s) and elevate intracellular cAMP. Certain G(s)-coupled(More)
Epidemiological evidence suggests a relationship between chronic inflammation and lung cancer. Inflammation in the lung may be modulated by host genetic factors such as polymorphisms in inflammatory genes. Identification of polymorphisms in inflammatory genes may help understanding interindividual differences in susceptibility to lung cancer. We have(More)
Exposure to tobacco smoke as well as environmental and occupational factors is the major cause of lung cancer. Non-small cell lung cancer (NSCLC) is the major histological type. Genes in pathways affecting inflammation, cellular stress and apoptosis are important, and the extent of inflammation in the lung could be affected by polymorphisms modifying these(More)
Environmental and occupational toxicants may induce pulmonary inflammation. Chronic inflammation has been linked to several human diseases and also to initiation and promotion of cancer. Generation of reactive oxygen/nitrogen species (ROS/RNS), secretion of cytokines, chemokines and pro-angiogenic factors are believed to play a role. Interleukin IL-1beta,(More)
Interleukin-1β (IL-1β), encoded by the IL1B gene, is a cytokine important in regulation of the inflammatory response. Elevated levels of IL1B expression have been associated with risk of gastric and lung cancer. We previously reported that a certain haplotype containing four single-nucleotide polymorphisms (SNPs) (−3893G, −1464G, −511C and −31T; GGCT) in(More)
