Microarray Analysis of Differentially Expressed Genes in human bronchial cells(BEAS-2B) treated MTX

ABSTRACT: Methotrexate (MTX) has been widely used for the treatment of a variety of tumors as well as for inflammatory diseases and rheumatoid arthritis (RA). MTX-induced toxicity has been a serious unpredictable side effect of the treatment and an important clinical problem. Possible causes include allergic, cytotoxic or immunologic reactions to this agent. We examined the consequences of the mechanism of MTX-induced pulmonary toxicity gene expression in BEAS-2B cells, huma bronchial cell line, by microarray. The expression of these genes are potential biomarker of methotrexate-induced pulmonary toxicity. Also, We provide a clue about mechanism of pulmonary toxic action by these clinical chemotherapeutic agents. Keywords: 48h treatment, 0.144uM (dose), MTX

Transcription profiling of human bronchial cells(BEAS-2B) treated with methotrexate

Project description:Methotrexate (MTX) has been widely used for the treatment of a variety of tumors as well as for inflammatory diseases and rheumatoid arthritis (RA). MTX-induced toxicity has been a serious unpredictable side effect of the treatment and an important clinical problem. Possible causes include allergic, cytotoxic or immunologic reactions to this agent. We examined the consequences of the mechanism of MTX-induced pulmonary toxicity gene expression in BEAS-2B cells, huma bronchial cell line, by microarray. The expression of these genes are potential biomarker of methotrexate-induced pulmonary toxicity. Also, We provide a clue about mechanism of pulmonary toxic action by these clinical chemotherapeutic agents. Experiment Overall Design: BEAS-2B cells were seeded and after incubation for 24 h at 37C, the cells were treated with 0.144 ?M(IC20) MTX for 48 h. And after total RNA isolation, gene expression analysis was conducted using a 44-k whole human genome microarray. Labeling and hybridization were performed using a FairPlay microarray labeling kit, followed by the coupling of Cy3 (controls) or Cy5 (treated samples) dye. The hybridized slides were scanned using a GenePix 4000B microarray scanner, and the images were analyzed using GenePix 4.1 software to obtain gene expression ratios. The fluorescence intensity of each spot was calculated by local median background subtraction. We then used the robust scatter-plot smoother LOWESS function to perform intensity-dependent normalization of gene expression. Scatter-plot analysis was performed using Microsoft Excel 2000. A significance analysis of microarray (SAM) was performed for genes with significant changes in expression.

Human bronchial cells (BEAS-2B) treated with amiodarone (AM)

Project description:AAmiodarone is an antiarrhythmic drug and representatively induce pulmonary phospholipidosis. Amiodarone-induced toxicity has been a serious unpredictable side effect of the treatment and an important clinical problem. Possible causes include allergic, cytotoxic or immunologic reactions to this agent. We examined the consequences of the mechanism of amiodarone-induced pulmonary toxicity gene expression in BEAS-2B cells, huma bronchial cell line, by microarray. The expression of these genes are potential biomarker of amiodarone-induced pulmonary toxicity. Also, We provide a clue about mechanism of pulmonary toxic action by these clinical chemotherapeutic agents. BEAS-2B cells were seeded and after incubation for 24 h at 37C, the cells were treated with 29.388 μM(IC20) amiodarone for 48 h. And after total RNA isolation, gene expression analysis was conducted using a 44-k whole human genome microarray. Labeling and hybridization were performed using a FairPlay microarray labeling kit, followed by the coupling of Cy3 (controls) or Cy5 (treated samples) dye.

Expression data from BEAS-2B cells

Project description:BEAS-2B cells are human bronchial epithelial cells, and often used as a in vitro model for the detection of potential pulmonary toxicity of chemicals. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated genes after treated with chemical substance

Expression data from proximal jejunum of WT vs. TLR2 KO mice after methotrexate (MTX) treatment

Project description:The role of innate immunity in modulating severity of chemotherapy-induced complications is so far unclear. The aim of this study was to determine how TLR2 may influence MTX-induced mucositis in the small intestine in mice. We used microarrays to assess gene expression profiles in proximal jejunum of WT vs. TLR2 KO mice after systemic treatment with MTX. Mucositis was induced by i.p. injection of MTX [40mg/kg BW/d] for 4 days in WT or TLR2 knockout (KO) mice. On day 7, mice were sacrificed and RNA was extracted from proximal jejunum (n=3 mice/group) and hybridized on Affymetrix microarrays.

Therapeutic Single-Cell Landscape: Methotrexate Exacerbates Interstitial Lung Disease by Compromising the Stemness of Alveolar Epithelial Cells under Systemic Inflammation

Project description:Interstitial lung disease (ILD) poses a serious threat in patients with rheumatoid arthritis (RA). However, the impact of cornerstone drugs, including methotrexate (MTX) and TNF blockade, on RA-associated ILD (RA-ILD) remains controversial. Our study using an SKG mouse model and single-cell transcriptomics revealed that MTX exacerbates pulmonary inflammation by promoting immune cell infiltration, Th17 activation, and fibrosis. In contrast, TNF blockade ameliorates these features and inhibits ILD progression. Analysis of data from a human RA-ILD cohort revealed that patients with ILD progression had persistently higher systemic inflammation than those without progression, particularly among the subgroup undergoing MTX treatment. These findings highlight the need for personalized therapeutic approaches in RA-ILD, given the divergent outcomes of MTX and TNF blockade.

Analysis of MTX-3937-treated human peripheral NK cells

Project description:Siglec-9 has been of particular interest for their potential as immune checkpoints. Here, we employed docking-based virtual screening combined with bio-layer interferometry assays to identify a potential Siglec-9 inhibitor, MTX-3937. Analysis showed that MTX-3937-treatment significantly enhanced the production of IFN-γ, TNF-α, perforin and CD107a in human NK cells. Consistently, MTX-3937 largely promoted NK cells tumor killing activities both in vitro and in vivo. In mechanism, MTX-3937 inhibited the phosphorylation level of SHP-1/2 in NK92 cells.
