Project description:A heterotrophic ammonia-oxidizing bacterium Alcaligenes sp. HO-1 was isolated from the activated sludge of a bioreactor treating ammonia-rich piggery wastewater. The goal and objectives of this experiment are to analyze the transcriptome profiles of nitrogen-metabolism-related genes of Alcaligenes sp. HO-1 in response to ammonium stimulation over time and to find out potential genes involved in ammonia oxidation process. So the RNA-seq anaylsis was performed by setting up each time points (0, 3.5, 10, 22 hours) when strain HO-1 were exposed to ammonia. HO-1 was cultured with 83 mM succinate and 14 mM ammonium sulfate until ammonia was completely consumed and then another 14 mM of ammonium sulfate was added to the culture. Cells were harvested at 0 h, 3.5 h, 10 h and 22 h after the addition of ammonium sulfate. The sequencing data of RNAs obtained from strain HO-1 cells at each time was analyzed.

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:Despite the high frequency of musculoskeletal extremity trauma, little is known about the dynamics of the initial inflammatory response that can result in pathologic healing. Here, we assess the circulatory monocyte/macrophage recruitment to sites of pathologic extremity wound healing as seen with heterotopic ossification (HO). Using single cell transcriptome analyses at key time points, we identify distinct monocyte/macrophage subpopulations that are recruited to the site of HO formation and contribute to ectopic bone development through varied transforming growth factor-1 (Tgfb1) expression. Monocyte/macrophage specific deletion of Tgfb1 leads to altered function of macrophages and reduced HO. We further identify CD47 as a novel target for Tgfb1 regulation on monocytes/macrophages as CD47 activation leads to decreased expression of Tgfb1 in macrophages and systemic treatment with CD47 activating peptide results in attenuation of canonical TGFB1 signaling and HO. These findings elucidate the critical role of monocytes/macrophage subpopulations in aberrant wound healing and provide a novel therapeutic avenue.
