Project description:Identification of mRNAs under translational control by Fhit
| PRJNA390535 | ENA
Project description:To obtain translational profiles for all mRNAs, polysome preparations are separated according to their size using a sucrose gradient and the mRNAs in each fraction are identified and quantified with DNA microarrays. Starting with exponentially growing cells, we analyzed 12 polysome fractions using DNA microarrays containing elements for all known and predicted genes of fission yeast. This approach provided data on average numbers of associated ribosomes for most transcripts.

Project description:The FHIT gene, at 3p14.2, encompasses the common fragile site FRA3B and is frequently inactivated in primary tumors and cell lines of lung, head and neck, stomach, esophagus, cervix and breast cancer. In particular, loss of the FHIT protein is one of the most frequent alteration in lung tumors and pre-invasive lung lesions, suggesting a role for this gene in the early stages of lung carcinogenesis. Adenoviral-mediated restoration of FHIT expression in FHIT-negative cell lines results in cell cycle alteration, induction of apoptosis (through activation of the cytoplasmic apoptotic pathway) and regression of the tumorigenic phenotype. Taken together these observations support the hypothesis of a role for FHIT in human carcinogenesis, but little is known about its mechanism of action. Identification of transcriptional targets of FHIT is therefore critical to understand the pathways by which FHIT promotes growth arrest and apoptosis.

Project description:Confluent human umbilical vein endothelial cells (HUVECs) were exposed to histamine (100 mM) for 2 hours. Ribosomal profiling via gradient centrifugation and fractionation was used to separate monosome, or under-translated, and polysome, or actively translated, mRNA species that were then used to probe cDNA arrays, a process known as Translation State Array Analysis (TSAA). Four samples were obtained from these experiments, control monosome, control polysome, histamine monosome and histamine polysome. Using the normalized signal intensities from the GeneFilters, we calculated a translation index, or measure of movement of an mRNA molecule from the monosome to the polysome fraction upon stimulation. This calculation was made as follows: (histamine polysome/histamine monosome)/(control polysome/control monosome). Translational indices greater than 2.5 (upregulated) or lower than 0.4 (downregulated) were chosen for further study. Keywords: Translation State Array Analysis

Project description:The purpose of the experiment is to identify mRNAs under differential translational control in Ki-ras transformed 267B1 cells as compared to the parental cell line. Total and polysome-associated mRNAs were isolated from exponentially growing cells and used to prepare biotin-labeled cRNA probes for analysis on Affymetrix microarray chips as described previously. The Data Mining tool (Affymetrix) was used to identify mRNAs that were differentially increased or decreased only in polysome fractions.

Project description:Confluent human umbilical vein endothelial cells (HUVECs) were exposed to Thrombin (2 U/mL) for 2 hours. Ribosomal profiling via gradient centrifugation and fractionation was used to separate monosome, or under-translated, and polysome, or actively translated, mRNA species that were then used to probe cDNA arrays, a process known as Translation State Array Analysis (TSAA). Four samples were obtained from these experiments, Control Monosome, Control Polysome, Thrombin Monosome, and Thrombin Polysome. Using the normalized signal intensities from the GeneFilters, we calculated a translation index, or measure of movement of an mRNA molecule from the monosome to the polysome fraction upon stimulation. This calculation was made as follows: (thrombin polysome/thrombin monosome)/(control polysome/control monosome). Translational indices greater than 2.5 (upregulated) or lower than 0.4 (downregulated) were chosen for further study. TSAA data suggests that JunB is translationally regulated by thrombin stimulation. Immunocytochemistry, western blotting and RT-PCR were used to verify the results of TSAA.
