Project description:A model of tumor metastasis based on v-src transformed immortalized cell lines was developed. The model consists of highly metastatic PR9692 cell line and a derived clone PR9692-E9 which has lost the metastatic abilities. Introduction of exogenous EGR1 gene into the non-metastasizing PR9692-E9 cells completely restores the metastatic potential. Revealed changes in gene expression provide insight into the molecular mechanisms contolling metastatic behavior of sarcoma cells. Comparison of expression profiles obtained from highly metastatic PR9692 cell line, derived non-metastatic clone PR9692-E9 and non-metastatic PR9692-E9 cells infected with replication-defective retroviral vector SFCVneo-EGR1 containing full length cDNA of EGR1. For each condition three biological replicates were analyzed.

Project description:Cell transformation by the Src tyrosine kinase is characterized by extensive changes in gene expression. To describe these changes, investigators have relied extensively on the study of immortalized rodent cell lines or heterogeneous tumor samples that limit the identification of differentially expressed genes or may not represent the full spectrum of biological processes regulated during transformation. In this study, we took advantage of transformation-deficient and temperature sensitive mutants of the Rous sarcoma virus to characterize the patterns of gene expression in two types of primary cells, namely chicken embryo fibroblasts (CEF) and chicken neuro-retinal (CNR) cells. Keywords: viral transformation of primary cells, transformation, transformation deficient mutant, temperature sensitive mutant, v-Src Chicken embryo fibroblasts (CEF) were infected with the wild-type strain Schmidt-Ruppin A RSV or non-transforming strain NY315 RSV or the non-transforming control virus RCASBP(A) to assess genes involved in v-Src-dependent transformation of CEF. Chicken embryo fibroblasts (CEF) were infected with the temperature sensitve strain NY72-4 RSV and cultured either at non-permissive temperature (41.5M-KM-^ZC) or permissive temperature (37M-KM-^ZC) to assess genes involved in v-Src-dependent transformation of CEF. Chicken neuroretina cells (CNR) were infected with the temperature sensitve strain NY72-4 RSV and cultured either at non-permissive temperature (41.5M-KM-^ZC) or permissive temperature (37M-KM-^ZC) to assess genes involved in v-Src-dependent transformation of CNR and compared to CEF.

Project description:Gene expression profiling of sarcoma cell lines of increasing metastatic potential: SW684 (low grade), HT1080 (high grade), GCT (metastatic). Differential gene expression may elucidate biomarkers of tumour progression and metastasis. Common reference design. Reference cell line: Pooled Normal fibroblast cell line MRC5, labelled with Alexa Fluor 555 (Cy3) in every experiment. Samples: Sarcoma cell lines labelled with Alexa Fluor 647 (Cy5). At least 3 replicates for each tumour grade.

Project description:Relative expression levels of mRNAs in chicken cecal epithelia experimentally infected with Eimeria tenella were measured at 4.5 days post-infection. Two weeks old chickens were uninfected (negative control) or were orally inoculated with sporulated oocysts of Eimeria tenella. Cecal epithelia samples were collected from >12 birds in infected or uninfected group at 4.5 d following infections, in which samples from 4 birds were pooled together to form a total 3 biological replicates in each group. Parasite merozoites were also collected from four infected chickens at 5 d after infections. Uninfected control samples, merozoites and infection group samples were selected for RNA extraction and hybridization on Affymetrix microarrays. We used Affymetrix GeneChip chicken genome arrays to detail the chicken cecal epithelia gene expression in the control and E. tenella-infected birds.
