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).
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.
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.
Project description:Investigation of whole genome gene expression level changes in HT1080 fibrosarcoma cell line after transfection CRABP1 gene and R131A CRABP1 mutant (arginine-alanine substitution in a protein active site, protein lacks the ability to interact with retinoic acid), compared to HT1080 line transfected with empty pLXSN vector. A twelve samples on one chip study using total RNA recovered from four separate cultures of HT1080 human fibrosarcoma cell line transfected with empty pLXSN vector, four HT1080 cell line cultures transfected with CRABP1 gene and four HT1080 cell line cultures transfected with R131A CRABP1 mutant. Each sample on a chip measures the expression level of 44,049 genes from human genome with three-fold technical redundancy.
Project description:Fibrosarcoma cell lines were generated from wild-type and Tnfaip8 knockout mice. After stimulation with vehicle, LPA, or PDGF, RNAs were collected from the cells afterwards for RNA-Seq.
