Project description:The aim was to determine the effect of heme oxygenase-1 (HO-1) overexpression on microRNA transcriptome in human non-small cell lung carcinoma cell line (NCI-H292). Since the cells of different HO-1 genotypes were used (cells are after retroviral transduction with empty vector with normal level of HO-1 or retroviral transduction with vector harboring HO-1), it is possible get the comprehensive answer which microRNAs are regulated by HO-1. Confluent NCI-H292 cells that contain EV-ctrl or overexpressing HO-1. Pool of reference cells are cells untreated and treated with 10 ng/ml TNF-M-NM-1 for 6 hours before RNA isolation. The samples are biological triplicates - three independent experiments were performed at different time points for all cell lines. Total number of the presented samples is 6.

Project description:Heme Oxygenase-1 (HO-1) is expressed in many cancers and influences the growth, survivall and metastasis of tumors, however, the molecular mechanisms remains largely unknown. To identify a common mechanism of action of HO-1 in cancer, we studied the global effect of HO-1 on the transcriptome of multiple tumors. Genome-wide expression profiling of HO-1 expressing versus HO-1 silenced cancer cells and a further data mining analysis of the preexisting expression database of 190 human tumors of 14 cancer types led us to identify 14 genes, the expression of which correlated firmly and universally with that of HO-1 (P < 0.001). These genes included regulators of cell plasticity and extracellular matrix remodeling (MMP2, ADAM8, TGFβ1, BGN, COL21A1, PXDN), signaling (CRIP2, MICB), amino acid transport and glycosylation (SLC7A1 and ST3GAL2), estrogen and phospholipid biosynthesis (AGPAT2 and HSD17B1), protein stabilization (IFI30) and phosphorylation (ALPPL2). PXDN, one of the genes being co-expressed with HO-1, was selected for further analysis. Immunofluorescence and western blotting confirmed positive correlation of PXDN with HO-1 levels in BeWo cancer cells as well as co-localization in invasive extravillous trophoblast cells of first trimester placenta. Loss of HO-1 in BeWo cells correlated with reduced cell adhesion to Collagen type I, Fibronectin and Laminin. The adhesion-promoting effects of HO-1 were dependent on PXDN expression, as loss of PXDN in HO-1 expressing BeWo cells led to reduced cell attachment to Laminin and Fibronectin coated wells. We used gene expression profiling to determine the genome-wide effect of HO-1 on the transcriptome of BeWo trophoblast cells. We specifically selected BeWo cells for our studies because these cells express HO-1 naturally. We knocked down endogenous HO-1 in BeWo cells using retroviral transduction with a micro-RNA adapted retroviral vector targeting human HO-1 sequence. RNA isolated from control (LMP) or miHO1 infected (miHO-1) cells was labeled and hybridized to human genome-wide gene level 1.0 ST arrays

Project description:The enzymatic activity of HO-1 results in decreased oxidative stress, attenuated inflammatory response, and very often in a lower rate of apoptosis. This is due to removal of heme, a potent prooxidant and proinflammatory agent, but mainly because of generation of biologically active products such as CO and bilirubin. In order to find the correlation between the HO-1 level and the expression of different genes of interest we have utilized human lung cancer cell line NCI-H292 stably overexpressing HO-1. Additionally we have checked if HO-1 can modulate genes expression in NCI-H292 cells treated with TNF. The effect of HO-1 overexpression on transcriptome was assessed by microarray analysis. We have observed that the increase in HO-1 level may affect the expression of different genes involved in cytokine synthesis, angiogenesis, apoptosis, proliferation and cell adhesion. Additionally, HO-1 may interact with the TNF treatment and influence the expression of some genes like IL-1, IL-6, IL-8, FAS and NF-kB.

NCI-H292 cells, control (pcDNA) and stably overexpressig HO-1 (pcHO1) were treated for 24 h with TNF (30 ng/ul), then the cells were lysed and RNA was collected. The whole human gene expression profile was assessed with Agilent microarray analysis. Three independent experiments were performed at each time using different batch of cells.

Project description:We compared the gene expression stimulated with fungal extracts from Aspergillus (A.) fumigatus, Alternaria (A.) alternata, or Penicillium (P.) notatum in NCI-H292 (a human bronchial epithelial cell line) to search Allergic bronchopulmonary mycosis (ABPM)-related genes. We identified a mucin-related MUC5AC gene, the expression of which was selectively induced by A. fumigatus. Total RNA from NCI-H292 cells stimulated for 24 h with the A. fumigatus, A. alternata, or P. notatum fungi extracts was extracted and subjected to microarray analysis. Each experiments were perfomed once for each stimulus.

Project description:Excessive accumulation of white adipose tissue (WAT) is a hallmark of obesity. The expansion of WAT in obesity involves proliferation and differentiation of adipose precursors (APs), however, the underlying molecular mechanisms remain unclear. Here, we identify Heme Oxygenase-1 (HO-1) as selectively being upregulated in the AP fraction of WAT, upon high-fat diet (HFD) feeding. Specific conditional deletion of HO-1 in APs of Hmox1fl/fl-Pdgfra Cre mice enhanced HFD-dependent visceral AP proliferation and differentiation, upstream of Cebpα and PPARγ. Opposite effects on human preadipocyte proliferation and differentiation in vitro were observed following HO-1 overexpression. Mechanistically, HO-1 acts upstream of AKT2 via ROS thresholding in mitochondria. Deletion of HO-1 in APs is sufficient to lower blood glucose, insulin and free fatty acid levels as well as liver steatosis during obesity, an effect not seen when HO-1 was conditionally deleted at later stages of adipogenesis using AdipoQ-Cre. Together, our data identify HO-1 as a diet-induced regulator limiting visceral adipose tissue hyperplasia during obesity.
