MicroRNAs are a family of small, non-coding RNAs that regulate gene expression in a sequence-specific manner. We propose a computational method to predict miRNA regulatory modules or groups of miRNAs and target genes that are believed to participate cooper ...
Quantitative PCR (qPCR) is a powerful technique that is now commonly used in many research and clinical laboratories. Although it allows precise quantification of specific DNA sequences, it is often not used at its full potential. A number of data collecti ...
Quantitative reverse transcriptase real-time PCR (QRT-PCR) is a robust method to quantitate RNA abundance. The procedure is highly sensitive and reproducible as long as the initial RNA is intact. However, breaks in the RNA due to chemical or enzymatic clea ...
The coordinated regulation of gene expression is required for homeostasis, growth and development in all organisms. Such coordination may be partly achieved at the level of messenger RNA stability, in which the targeted destruction of subsets of transcript ...
The Gam1 protein of the avian CELO adenovirus activates transcription through inhibition of histone deacetylase 1 (HDAC1). We investigated the effect of Gam1 on both transient and stable transgene expression in Chinese hamster ovary (CHO) cells, one of the ...
The developmental regulation of vertebrate Hox gene transcription relies on the interplay between local and long-range controls. To study this complex genomic organization, we designed a strategy combining meiotic and targeted recombinations to induce larg ...
Identification of the regulatory structures in genetic networks and the formulation of mechanistic models in the form of wiring diagrams is one of the significant objectives of expression profiling using DNA microarray technologies and it requires the deve ...
An important aspect of the development of systems biology approaches in metazoans is the characterization of expression patterns of nearly all genes predicted from genome sequences. Such "localizome" maps should provide information on where (in what cells ...
Recent advances in genomics, proteomics, and structural biology raised the general need for significant amounts of pure recombinant protein (r-protein). Because of the difficulty in obtaining in some cases proper protein folding in bacteria, several method ...
Mutations in Cu/Zn superoxide dismutase (encoded by SOD1), one of the causes of familial amyotrophic lateral sclerosis (ALS), lead to progressive death of motoneurons through a gain-of-function mechanism. RNA interference (RNAi) mediated by viral vectors a ...
