Project description:The objective of this study was to analyze the mitochondrial mutations induced by chronic cigarette smoke extract treatment in human oral immortal OKF6 cells. The objective of this study was to analyze the mitochondrial mutations induced by chronic cigarette smoke extract treatment in human oral immortal OKF6 cells. 2 samples were included, a control passaged human oral immortal OKF6 cells and cigarette smoke extract-treated OKF6 cells. The chronic treatment for cigarette smoke extract is 7 months. Genomic DNAs were extracted from both cells and then used for Affymetix MitoChip Version 2.0 analysis.
Project description:hAEC cells were exposed to cigarette smoke extract (CSE) or PBS for 48h, and gene expression was evaluated by RNA-seq.In this study we explored the effect of cigarette smoke on the gene expression profile.
Project description:This study was performed to test the hypothesis that cigarette smoke extract would alter the responses of primary cultures of human bronchial epithelial cells to infection with purified human rhinovirus 16. The data show marked alterations in rhinovirus-induced expression profiles of a number of genes in the presence of cigarette smoke extract (CSE).
Project description:Endothelial cells (HUVEC) were exposed to cigarette smoke extract for 3, 7, and 24 hours. Total RNA was isolated and used for hybridisation to dual channel oligonucleotide genome-wide microarrays using untreated HUVEC as a control. The objective was to find out what genes are regulated by exposure to cigarette smoke extract, and the time dependency of their regulation Keywords: time course, stress response
Project description:Human alveolar epithelial cells were exposed to cigarette smoke extract (CSE) for 1, 3 and 5 weeks at 1%, 5% and 10%, and gene expression was evaluated by complete transcriptome microarrays. In this study we explored the effect of cigarette smoke on the gene expression profile.
Project description:To investigate the underlying mechanism of damage to bone and bone marrow mesenchymal stem cells stimulated by cigarette smoke extract (CSE)
Project description:To understand the effect of nicotine on sensitivity of cancer cells to radiation or anti-cancer drugs, NCI-H460 human lung large cell carcinoma cells were treated with 6 Gy ionizing radiation or 1 uM cisplatin after exposure to 0.5 uM nicotine or cigarette smoke extract. MicroRNA expression in total RNA extracted from the treated cells was quantified using the 7th generation miRCURY™ locked nucleic acid microarray platform from Exiqon® (Vedbaek, Denmark).
Project description:Chronic obstructive pulmonary disease (COPD) is currently the third cause of death worldwide with still increasing mortality and morbidity. Primary etiology of COPD is cigarette smoking. However, in clinic, not all smokers develop COPD. The underlying mechanism remains unclear. A549 cells, which are widely used in vitro as a model of alveolar type II pulmonary epithelium, were subjected to step-wise increasing cigarette smoke extract (CSE) treatments. Those cigarette smoke extract resistant (SER) cells were cultured and used for further experiments. The aim of this study is to investigate the differentially expressed genes in SER group with or without CSE treatment and identify potential genes or pathways which could play a role in COPD pathogenesis.
Project description:The current study was performed for analysis of the biological effects of vapor from novel tobacco vapor product in comparison with 3R4F cigarette smoke. This study was performed using a three-dimensional culture system composed of an air-liquid interface culture of primary normal human bronchial epithelial cells (MucilAir). The MucilAir tissues were subjected to 17 days of exposure to the aqueous extract of novel tobacco product vapor or 3R4F cigarette smoke. The number of differentially expressed genes increased in MucilAir tissues exposed to aqueous extract of each test product dependent on exposure duration. The number of differentially expressed genes was lower in the tissues exposed to aqueous extract of novel tobacco product vapor compared to the tissues exposed to aqueous extract of 3R4F cigarette smoke.
