Project description:Investigation of whole genome gene expression level changes in a colorectal cancer cell line SW480 expressing FOXC2, compared to the pBabe control cells. Genes associated with metastasis regulated by FOXC2 in colorectal cancer were analysed. The role of FOXC2 in breast cancer metastasis are further described in Mani SA, Yang J et al. Mesenchyme Forkhead 1 (FOXC2) plays a key role in metastasis and is associated with aggressive basal-like breast cancers. PNAS 2007; 104: 10069-10074 .
Project description:Huh7/5-2 cells (Binder et al., Hepatology 2007) were mock infected (DMEM) (time points 4 and 48 h) or infected with the chimeric HCV virus Jc1 (Pietschmann et al., PNAS 2006) (all time points). Multiplicity of infection was 15 (TCID50). Cells were lysed after 4, 12, 24, 48 and 72 hours post infection and total cellular RNA was prepared.
Project description:FVB mice were engineered to express wild-type human cyclin E under control of the human surfactant C promoter (CEO mice; Ma et al, PNAS 2007). These mice develop spontaneous lung tumors, which were shown to be adenocarcinoma by histological analysis. Here we compare whole-genome RNA expression levels between the tumors and normal lung of 4 CEO mice as well as 4 nontransgenic animals.

Multiplicity of infection was 15 (TCID50). Cells were lysed after 4, 12, 24, 48 and 72 hours post infection and total cellular RNA was prepared. Mock infected cells serve as controls for the infected samples. The whole experiment was repeated on independent days (2 biological replicates). The dataset was also submitted to GEO (GSE38720).
Project description:The goal of the experiment was to obtain a replicate of the wild-type LL circadian timecourse published in Vijayan et al, PNAS 106: 22564-22568 (2009), in order to identify reproducible circadian genes in LL.

A six chip study using total RNA recovered from three separate cultures of SW480/pBabe and three separate cultures of SW480/FOXC2. Each chip measures the expression level of 45033 genes from SW480/pBabe or SW480/FOXC2.
Project description:Muscular atrophy (SMA) is an autosomal recessive disease causing selective motor neuron death by the loss of telomeric survival motor neuron gene, SMN1. Axonal SMN, a-SMN, is a truncated form of SMN, derived from an alternatively spliced SMN1 gene. (Setola, et. al. 2007 PNAS 104, 1959-1964). The cellular clones expressing a-SMN in a tetracycline-dependent manner were isolated from NSC34 by two-step stable transfection, first with the tetracycline-repressor construct and subsequently with the a-SMN cDNA. To identify novel a-SMN target genes, the transcriptome of several a-SMN clones was analyzed and compared with that of parental cells.
Project description:FVB mice were engineered to express wild-type human cyclin E under control of the human surfactant C promoter (CEO mice; Ma et al, PNAS 2007). These mice develop spontaneous lung tumors, which were shown to be adenocarcinoma by histological analysis. Here we compare whole-genome RNA expression levels between the tumors and normal lung of 4 CEO mice as well as 4 nontransgenic animals. RNA was isolated from the lungs of 4 FVB mice and adjacent normal and tumor tissue from 4 FVB transgenes harboring human surfactant protein C- driven wild-type human cyclin E, all 7-11 months in age. These samples were divided into 3 groups of four, and 12 independent hybridizations were performed for analysis with Affymetrix GeneChip Mouse 430 2.0 arrays.
