Methylation profiling by array of human carcinoma cells

ABSTRACT: Genomic DNA from cell lines was extracted and treated with sodium bisulfite. Fragments were PCR-amplified from the treated template DNA, labelled and hybridized to the microarray. The array contained probe sequences complementary to formerly methylated (M) and unmethylated (U) cytosines respectively. Hence the signal intensity ratio from M/(M+U) represents each cytosines methylation level in percent.

DNA methylation in Breast cancer

Project description:This experiment was performed with an aim to establish an early diagnostic marker for breast cancer based on the DNA methylation patterns. CpG Island were identified and amplified from the breast cancer related genomic loci. These selected loci were amplified using PCR from different human breast tissue samples. The samples included Breast cancer tissues and macroscopically normal tissues (3-5cm away from tumor) from breast cancer patients, benign breast tissues and healthy breast tissues from cancer free patients. All the genomic loci amplified from one particular tissue sample were pooled, biotin labeled and hybridized to a self designed and synthesised oligonucleotide microarray. The obtained signals were statistically analysed and the genomic loci which could differentiate the different kinds of breast tissues used based on their methylation levels are being reported.

shRNA profiling of human cells containing varying concentrations of shRNA expression constructs to determine shRNA abundance using barcodes

Project description:RNAi screens via pooled short hairpin RNAs (shRNAs) have recently become a powerful tool for the identification of essential genes in mammalian cells. We synthesized DNA microarrays with six overlapping 25 nt long tiling probes complementary to each unique 60 nt molecular barcode sequence associated with every shRNA expression construct. By analyzing dilution series of expression constructs we show how our approach allows quantification of shRNA abundance from a pool and how it clearly outperforms the commonly used analysis via the shRNAs half hairpin sequences. In this part of the study one equimolar reference pool and three test pools of varying template concentrations were PCR amplified and hybridized to individual arrays.

shRNA profiling of human breast carcinoma cells expressing over 300 shRNA constructs using barcode tiling arrays - screen 1

Project description:RNAi screens via pooled short hairpin RNAs (shRNAs) have recently become a powerful tool for the identification of essential genes in mammalian cells. We synthesized DNA microarrays with six overlapping 25 nt long tiling probes complementary to each unique 60 nt molecular barcode sequence associated with every shRNA expression construct.. In this part of the study pooled shRNAs were transduced into MDA-MB-231 breast carcinoma cell lines and their inhibitory effects four weeks post transduction were analyzed via microarray hybridization.

Transcription profiling of Listeria monocytogenes after infection into murine macrophages

Project description:P388D1 murine macrophages were cultured in 85 mm tissue culture plates to about semi confluency. L. monocytogenes serotypes (1/2a EGD-e, 4a L99, 4b CLIP80459 and 4b F2365) were infected to the P388D1 cell monolayer at a MOI of 100 per eukaryotic cell. Infection was carried for 45 min and followed by addition of fresh medium containing 20 M-5g/ml gentamicin. The medium of the plates (containing 20 M-5g/ml gentamicin) infected with L. monocytogenes serotypes were replaced after 2 h post infection with fresh medium containing 50 M-5g/ml gentamicin. At each step the plates were washed extensively with 1x PBS. Incubation of the bacterial tissue culture plates was carried out in a humidified incubator for up to 4 h post infection.

CGH analyses of human induced pluripotent stem cells

Project description:Human induced pluripotent stem cells (hIPSCs) represent a unique opportunity for regenerative medicine since they offer the prospect of generating unlimited quantities of cells for autologous transplantation as a novel treatment for a broad range of disorders. However, the use of hIPSCs in the context of genetically inherited human disease will require correction of disease-causing mutations in a manner that is fully compatible with clinical applications. Genomic instability induced by reprogramming or genetic modification would be a main issue for the safe use of these cells. We analyzed primary hIPSC lines and genetically modified derivatives by array-based comparative genomic hybridization.
