Targets of cytostatic drugs in HT1080 fibrosarcoma

ABSTRACT: HT1080 fibrosarcoma cells were treated with cytostatic drugs and analysed on Affymetrix microarray to identify genes and pathways regulated by these compounds. The array images were processed using Affymetrix MAS 5.0 software. and normalized by global scaling or scaled to a polyA+ spike mask Keywords = Cytostatic drugs Keywords = Actinomycin D Keywords = Doxorubicin Keywords = Vincristine Keywords = apoptosis Keywords: ordered

Expression data from RECK-overexpressing HT1080 fibrosarcoma cells

Project description:RECK, a glycosylphosphatidylinositol-anchored glycoprotein, inhibits the enzymatic activities of some matrix metalloproteinases (MMP), thereby suppressing tumor cell metastasis; however, the detailed mechanism is still obscure. In this study, we compared the gene expression profiles between mock- and RECK-transfected HT1080 cells. Three established cell lines were selected for RNA extraction and hybridization on Affymetrix microarrays: (1) mock-transfected HT1080 cells, designated as HT1080-Zeo, (2) RECK-overexpressing HT1080 cells, designated as HT1080-RECK, and (3) RECK/4NQ-overexpressing HT1080 cells (in which four N-glycosylation asparagine residues of RECK (Asn86, Asn200, Asn297, and Asn352) were replaced with glutamine residues), designated as HT1080-RECK/4NQ.

Proteomic profiling of HT1080 fibrosarcoma cells of mesenchymal or amoeboid migratory phenotype

Project description:Amoeboid and mesenchymal migration of cancer cells both contribute to metastatic spreading of tumors. To characterize proteome changes underlying the different migratory modes, we performed mass spectrometry profiling of HT1080 fibrosarcoma cells undergoing mesenchymal-amoeboid transition induced by either doxycycline-inducible constitutively active RhoA or dasatinib treatment. Cells were kept in three-dimensional collagen gels with or without induction for 48 hours, lysed and processed for mass spectrometry analysis. In case of the inducible RhoA system, we also performed parallel two-dimensional experiments with cells on top of a dense layer of collagen (it was not feasible with dasatinib treatment).

Transcriptomic profiling of HT1080 fibrosarcoma cells of mesenchymal or amoeboid migratory phenotype

Project description:Amoeboid and mesenchymal migration of cancer cells both contribute to metastatic spreading of tumors. To characterize gene expression profiles underlying the different migratory modes, we performed RNA sequencing of HT1080 fibrosarcoma cells undergoing mesenchymal-amoeboid transition induced by either doxycycline-inducible constitutively active RhoA or dasatinib treatment. Cells were kept in three-dimensional collagen gels with or without induction for 48 hours. RNA was isolated with a modified Chomczynski protocol. RNA-seq libraries were constructed from DNase I treated, rRNA depleted total RNA and sequenced with Illumina 2000/2500 sequencers.

Mechlorethamine-induced DNA-protein cross-linking in human fibrosarcoma (HT1080) cells.

Project description:Antitumor nitrogen mustards, such as bis(2-chloroethyl)methylamine (mechlorethamine), are useful chemotherapeutic agents with a long history of clinical application. The antitumor effects of nitrogen mustards are attributed to their ability to induce DNA-DNA and DNA-protein cross-links (DPCs) that block DNA replication. In the present work, a mass spectrometry-based methodology was employed to characterize in vivo DNA-protein cross-linking following treatment of human fibrosarcoma (HT1080) cells with cytotoxic concentrations of mechlorethamine. A combination of mass spectrometry-based proteomics and immunological detection was used to identify 38 nuclear proteins that were covalently cross-linked to chromosomal DNA following treatment with mechlorethamine. Isotope dilution HPLC-ESI(+)-MS/MS analysis of total proteolytic digests revealed a concentration-dependent formation of N-[2-(S-cysteinyl)ethyl]-N-[2-(guan-7-yl)ethyl]methylamine (Cys-N7G-EMA) conjugates, indicating that mechlorethamine cross-links cysteine thiols within proteins to N-7 positions of guanine in DNA.

Suppression of MT1-MMP in Human Fibrosarcoma Impair Tumor Angiogenesis and Enlargement

Project description:To define the role of MT1-MMP in the tumor progression, we suppressed its expression in human fibrosarcoma cell line, HT1080, using RNAi technique. The gene expression pattern was then compared betweent the two experimental cell groups with contrasting MT1-MMP expression level. Keywords: other

1,2,3,4-Diepoxybutane-induced DNA-protein cross-linking in human fibrosarcoma (HT1080) cells.

Project description:1,2,3,4-Diepoxybutane (DEB) is the key carcinogenic metabolite of 1,3-butadiene (BD), an important industrial and environmental chemical present in urban air and in cigarette smoke. DEB is a genotoxic bis-electrophile capable of cross-linking cellular biomolecules to form DNA-DNA and DNA-protein cross-links (DPCs). In the present work, mass spectrometry-based proteomics was employed to characterize DEB-mediated DNA-protein cross-linking in human fibrosarcoma (HT1080) cells. Over 150 proteins including histones, high mobility group proteins, transcription factors, splicing factors, and tubulins were found among those covalently cross-linked to chromosomal DNA in the presence of DEB. A large portion of the cross-linked proteins are known factors involved in DNA binding, transcriptional regulation, cell signaling, DNA repair, and DNA damage response. HPLC-ESI(+)-MS/MS analysis of total proteolytic digests revealed the presence of 1-(S-cysteinyl)-4-(guan-7-yl)-2,3-butanediol conjugates, confirming that DEB forms DPCs between cysteine thiols within proteins and the N-7 guanine positions within DNA. However, relatively high concentrations of DEB were required to achieve significant DPC formation, indicating that it is a poor cross-linking agent as compared to antitumor nitrogen mustards and platinum compounds.
