Prokaryotic suppression subtractive hybridization PCR cDNA subtraction, a targeted method to identify differentially expressed genes.
Molecular biology tools can be used to monitor and optimize biological treatment systems, but the application of nucleic acid-based tools has been hindered by the lack of available sequences for environmentally relevant biodegradation genes. The objective of our work was to extend an existing molecular method for eukaryotes to prokaryotes, allowing us to rapidly identify differentially expresse...
متن کاملIdentifying Differentially Expressed Genes in cDNA Microarray Experiments
A major goal of microarray experiments is to determine which genes are differentially expressed between samples. Differential expression has been assessed by taking ratios of expression levels of different samples at a spot on the array and flagging spots (genes) where the magnitude of the fold difference exceeds some threshold. More recent work has attempted to incorporate the fact that the va...
متن کاملDifferentially expressed genes in gastric tumors identified by cDNA array.
Using cDNA fragments from the FAPESP/lICR Cancer Genome Project, we constructed a cDNA array having 4512 elements and determined gene expression in six normal and six tumor gastric tissues. Using t-statistics, we identified 80 cDNAs whose expression in normal and tumor samples differed more than 3.5 sample standard deviations. Using Self-Organizing Map, the expression profile of these cDNAs all...
متن کاملHunting for differentially expressed genes.
Differentially expressed genes are usually identified by comparing steady-state mRNA concentrations. Several methods have been used for this purpose, including differential hybridization, cDNA subtraction, differential display and, more recently, DNA chips. Subtractive hybridization has significantly improved after the polymerase chain reaction was incorporated into the original method and many...
متن کاملGeneration of full-length cDNA libraries enriched for differentially expressed genes for functional genomics.
Here, we describe the application of a RecA-based cloning technology to generate full-length cDNA libraries enriched for genes that are differentially expressed between tumor and normal tissue samples. First, we show that the RecA-based method can be used to enrich cDNA libraries for several target genes in a single reaction. Then, we demonstrate that this method can be extended to enrich a cDN...
