Scientist Solutions - DNA MicroArray Basics

Just came across this resource today, while looking up MicroArray companies. Its pretty nice and a great beginner step. DNA microarrays can be thought of as the massively parallel version of Northern blotting. While the Northern blotting technique is capable of analysing for each experiment the expression of one single gene in different conditions, microarrays allow the exploration of the expression levels of thousands of genes in several different conditions in one single run. As Northern blotting and many other classic techniques widely used in molecular biology, the fundamental basis of [more...]

Epigenetic Transgenerational Actions of Vinclozolin on Promoter ...

A methylated DNA immunoprecipitation with methyl-cytosine antibody followed by a promoter tilling microarray (MeDIP-Chip) procedure was used to identify 52 different regions with statistically significant altered methylation in the sperm promoter epigenome. Mass spectrometry bisulfite analysis was used to map the CpG DNA methylation and 16 differential DNA methylation regions were confirmed, while the remainder could not be analyzed due to bisulfite technical limitations. Analysis of these validated regions identified a consensus DNA sequence (motif) that associated with 75% of the promoters. [more...]

Natural Health News: Supplement Suppresses Breast Cancer Cells

Expression of cell cycle regulatory genes were determined by DNA-microarray analysis. Effect of BD on invasiveness was assessed by cellular adhesion, migration, and invasion assays. Results. BD treatment of cells MDA-MB-231 resulted in the cytostatic inhibition of cell proliferation with IC50 22.2, 19.1, and 17.5 μg/mL for 24, 48, and 72 hours, respectively. The inhibition of proliferation was mediated by the upregulation expression of CCNG1, CHEK1, CDKN1C, GADD45A, and E2F2, whereas BD downregulated expression of CCNA1 and CDK6 genes. The induction of expression of GADD45A and inhibition of [more...]

Gene association analysis: a survey of frequent pattern mining ...

Generation of DNA microarray gene expression data introduces a variety of data analysis issues not encountered in traditional molecular biology or medicine. Frequent pattern mining (FPM) has been applied successfully in business and scientific data for discovering interesting association patterns, and is becoming a promising strategy in microarray gene expression analysis. We review the most relevant FPM strategies, as well as surrounding main issues when devising efficient and practical methods for gene association analysis (GAA). We observed that, so far, scalability achieved by efficient [more...]

Chromosomal Microarray Analysis: Pros and Cons

Chromosomal Microarray Analysis: Pros and Cons Since the 1960s, the traditional way of screening for prenatal genetic disorders was through amniocentesis, an invasive procedure, which slightly increases the risk of miscarriage. A new method of genetic testing, called chromosomal microarray analysis, can detect submicroscopic genetic anomalies that other tests can not find. In this method, fetal DNA is obtained through a sample of a pregnant woman's blood. This technology is believed to be safer, faster and more accurate than the traditional, invasive test. While there are many benefits to [more...]

Role of p400/mDomino in Cell-cycle Progression [Dna and Chromosomes]

DNA microarray analysis revealed that the p400/mDomino deletion from MEFs caused the impaired expression of many cell-cycle-regulatory genes, including G2/M-specific genes targeted by the transcription factors FoxM1 and c-Myc. These results indicate that p400/mDomino plays a key role in cellular proliferation by controlling the expression of cell-cycle-regulatory genes.

Potential Bias in GO::TermFinder — Brief Bioinform

The increased need for multiple statistical comparisons under conditions of non-independence in bioinformatics applications, such as DNA microarray data analysis, has led to the development of alternatives to the conventional Bonferroni correction for adjusting P-values. The use of the false discovery rate (FDR), in particular, has grown considerably. However, the calculation of the FDR frequently depends on drawing random samples from a population, and inappropriate sampling will result in a bias in the calculated FDR. In this work, we demonstrate a bias due to incorrect random sampling in [more...]
