Cigarette smoke promote the tumor progression via FASN in bladder cancer and rewiring the fatty acid metabolism

Project description:Cigarette smoke has been demonstrated to stimulate the growth of existing bladder tumors by enhancing the survival and proliferation of cancer cells through the action of carcinogens present in smoke. Concurrently, Fatty Acid Synthase (FASN), a key enzyme in fatty acid synthesis crucial for lipid metabolism, exhibits dysregulation in various cancer types, often correlating with aggressive phenotypes. In this study, we reveal altered fatty acid metabolism and elevated FASN and fatty acid levels, specifically in current smokers with bladder cancer (BLCA). Notably, increased FASN levels under smoke exposure are attributed to epigenetic alterations affecting fatty acid metabolism. Cells exposed to cigarette smoke demonstrate a metabolic shift in utilizing glutamine as a carbon source and producing fatty acids. The genetic and pharmacological inhibition of FASN effectively reduces tumor growth in a CAM model exposed to smoke. FASN inhibitors like TVB 2640, currently in phase II clinical trialsclinical trials in various cancer types, may be effective for smokers with BLCA exhibiting high FASN levels. In general, FASN inhibition offers therapeutic promise for mitigating the impact of cigarette smoke on bladder cancer progression.

mouse lung resistance or sensitivity to cigarette smoke

Project description:We have investigated the effects of cigarette smoke exposure in three different strains of mice. DBA/2 and C57Bl/6J are susceptible to smoke and develop different lung changes in response to chronic exposure, while ICR mice are resistant to smoke and do not develop emphysema. The present study was carried out to determine early changes in the gene expression profile of mice exposed to cigarette smoke with either a susceptible or resistant phenotype.

Cigarette smoke induces mitochondrial metabolic reprogramming in lung cells

Project description:Cigarette smoking remains the leading cause of non-small cell lung carcinoma. Studies involving acute exposure of smoke on lung cells revealed induction of pre- cancerous state in lung cells. Recently few studies have reported the chronic effect of cigarette smoke in inducing cellular transformation. Yet no systemic study has been performed to understand the molecular alterations in lung cells due to cigarette smoke. Hence it is both important and necessary to study the chronic effect of cigarette smoke in a temporal setting to understand the molecular alterations. In this study, we carried out TMT based proteomic profiling of lung cells which were exposed to cigarette smoke condensate (CSC) for upto 12 months. We identified 2621 proteins in total, of which 145, 114, 87, 169 and 671 proteins were differentially expressed (p<0.05, 1.5 fold) in 2nd, 4th, 6th, 8th and 12th month respectively. Pathway analysis revealed enrichment of xenobiotic metabolism signaling for the first 8 months of smoke treatment, where as continued exposure of smoke for 12 months revealed mitochondrial reprogramming in cells which includes dysregulation of oxidative phosphorylation machinery leading to enhanced reactive oxygen species and higher expression of enzymes involved in tricarboxylic acid cycle (TCA). In addition, chronic exposure of smoke led to overexpression of enzymes involved in glutamine metabolism, fatty acid degradation and lactate synthesis. This could possibly explain the availability of alternative source of carbon in TCA cycle apart from glycolytic pyruvate. Our data indicates that chronic exposure to cigarette smoke induces mitochondrial metabolic transformation in cells to support growth and survival.

Time course of NHBE cells exposed to whole cigarette smoke

Project description:Gene expression patterns were assessed in normal human bronchial epithelial (NHBE) cells exposed to cigarette smoke from a reference cigarette (2R4F, University of Kentucky) and a typical American brand of "light" cigarettes ("Lights") in order to develop a better understanding of the genomic impact of tobacco exposure, which can ultimately define biomarkers that discriminate tobacco-related effects and outcomes in a clinical setting. NHBE cells were treated with whole cigarette smoke for 15 minutes and alterations to the transcriptome assessed at 2, 4, 8 and 24 hours post-exposure using high-density oligonucleotide microarrays. Keywords: time course, cigarette smoke exposure

Dissecting the molecular effects of cigarette smoke on proteasome function

Project description:Proteasome dysfunction is emerging as a novel pathomechanism for the development of chronic obstructive pulmonary disease (COPD), a major leading cause of death in the world. Cigarette smoke is one of the main risk factors for COPD and has been shown to impair proteasome function in vitro and in vivo. Importantly, proteasome activity is inhibited in COPD lungs while expression levels of proteasome subunits are not altered. In the present study, we dissected the molecular changes induced by cigarette smoke on proteasome function in lung epithelial cells and mouse lungs. We analyzed the integrity, composition, and the interactome of isolated 26S proteasome complexes from smoke-exposed cells and mouse lungs. Moreover, we applied native MS analysis to investigate whether reactive compounds of cigarette smoke directly modify and inhibit the 20S proteasome complex. Our data reveal that the 20S proteasome is slightly destabilized in the absence of any dominant modification of proteasomal proteins. 26S pulldown and stoichiometry analysis indicated that 26S proteasome complexes become instable in response to cigarette smoke exposure. Of note, the interactome of the 26S was clearly altered in smoke-exposed mouse lungs possibly reflecting an altered cellular composition in the lungs of the smoke-exposed mice. Taken together, our results suggest that cigarette smoke induces minor but detectable changes in the stability and interactome of 20S and 26S proteasome complexes which might contribute in a chronic setting to imbalanced proteostasis as observed in chronic lung diseases associated with cigarette smoking.
