- Gene Network Inference .
- Gene Expression Data.
- The traditional approach to research in Molecular Biology has been an inherently local one, examining and collecting data on a single gene, a single protein or a single reaction at a time. ...
- Can we really expect to construct a detailed biochemical model of, say, an entire yeast cell with some 6000 genes (only about 1000 of which were defined before sequencing started, and about 50% of which are clearly related to other known genes), by analyzing each gene and determining all the binding and reaction constants one by one? Likewise, from the perspective of drug target identification for human disease, we cannot realistically hope to characterize all the relevant molecular interactions one-by-one as a requirement for building a predictive disease model. ...

3. UNC Gene Therapy Center
- www.med.unc.edu
- The University of North Carolina School of Medicine created the Gene Therapy Center in 1996 with the goal of merging molecular genetics research with healthcare delivery. The Gene Therapy Center provides important resources to academic investigators through two core facilities created to support preclinical and clinical gene therapy studies. These facilities, the Vector Core and the Human Applications Laboratories, were created to ensure that investigators would have promising gene vectors available in the quality and quantities needed for preclinical or clinical studies. Research in the laboratory has centered on the molecular biology of adeno-associated virus (AAV) in order to exploit the unique features of this virus to develop an efficient viral vector system for use in human gene therapy. Continued efforts in understanding the mechanism of viral replication and integration for both wild-type and recombinant AAV are being pursued in order to create more efficient gene transfer vectors. The ultimate goal of the Gene Therapy Center is to facilitate the progression and translation of gene therapy research from the laboratory bench into Phase I clinical trials for the treatment of human disease.

4. Reporter gene - Wikipedia, the free encyclopedia
- en2.wikipedia.org
- Reporter gene.
- In molecular biology, a reporter gene (often simply reporter) is a gene that researchers attach to another they wish to study in cell culture, animals or plants. Many of the techniques used for engineering a foreign or modifed gene into an organism work only in a very small percentage of individuals. Researchers use a reporter to easily identify those that have taken up the gene, or which have incorporated it in the desired way into their chromosomes. A common reporter is the gene that encodes jellyfish green fluorescent protein, which causes cells that express it to glow green under UV light.
- Reporter genes are often placed downstream of the promoter region and in the proximity of the gene of interest to ensure that they are expressed together and not separated by crossover events.

- www.cse.ucsc.edu
- Knowledge-based Analysis of Microarray Gene Expression Data Using Support Vector Machines.
- ABSTRACT: We introduce a new method of functionally classifying genes using gene expression data from DNA microarray hybridization experiments. ... SVMs are considered a supervised computer learning method because they exploit prior knowledge of gene function to identify unknown genes of similar function from expression data. ... SVMs have many mathematical features that make them attractive for gene expression analysis, including their flexibility in choosing a similarity function, sparseness of solution when dealing with large data sets, the ability to handle large feature spaces, and the ability to identify outliers. ...

- Regulatory Gene Defects in Cancer.
- cystic fibrosis) in which a single defective gene is always responsible, cancers which appear clinically similar can be genetically heterogeneous. For example, prostate cancer (prostatic adenocarcinoma) may be caused by several different, independent regulatory gene defects even in a single patient. ...
- In this way, the experimenter can watch as the gene transcription patterns change from the old to the new steady state. ...
- These activities require quite different gene products, such as DNA polymerases for genome replication or microtubule spindle proteins for mitosis. A cell's genes encode the "programs" for these activities, and gene transcription is required to execute those programs. ...
- The transcription level of a gene is taken to be the amount of its corresponding mRNA present in the cell. ...
- For organisms whose genomes have been completely sequenced, including several bacteria and the the yeast Saccharomyces cerevisciae, it is possible to array genomic DNA from every known gene or suspected open reading frame (ORF) in the organism. Each gene or ORF is amplified from total genomic DNA by PCR, producing enough DNA to make unlimited numbers of arrays. ...
- While neither of these methods will produce DNA's for every human gene, both can yield enough different expressed sequences to make substantial arrays. ...

- GENSCAN - predict complete gene structures .
- GENSCAN is a program designed to predict complete gene structures, including exons, introns, promoter and poly-adenylation signals, in genomic sequences. It differs from the majority of existing gene finding algorithms in that it allows for partial genes as well as complete genes and for the occurrence of multiple genes in a single sequence, on either or both DNA strands. The program is based on a probabilistic model of gene structure/compositional properties and does not make use of protein sequence homology information. ...
10. Control of Gene Expression
- web.indstate.edu
- Control of Gene Expression in Prokaryotes .
- Control of Gene Expression in Eukaryotes .
- The controls that act on gene expression (i. ... , the ability of a gene to produce a biologically active protein) are much more complex in eukaryotes than in prokaryotes. ... Whereas, in prokaryotes, control of transcriptional initiation is the major point of regulation, in eukaryotes the regulation of gene expression is controlled nearly equivalently from many different points. ...
- back to the top Gene Control in Prokaryotes .
- In bacteria, genes are clustered into operons: gene clusters that encode the proteins necessary to perform coordinated function, such as biosynthesis of a given amino acid. ... In bacteria, control of the rate of transcriptional initiation is the predominant site for control of gene expression. ... One mode of regulation is exerted upon operons that produce gene products necessary for the utilization of energy; these are catabolite-regulated operons. The other mode regulates operons that produce gene products necessary for the synthesis of small biomolecules such as amino acids. ...
- The lac operon (see diagram below) consists of one regulatory gene (the i gene) and three structural genes (z, y, and a). The i gene codes for the repressor of the lac operon. The z gene codes for b-galactosidase (b-gal), which is primarily responsible for the hydrolysis of the disaccharide, lactose into its monomeric units, galactose and glucose. The y gene codes for permease, which increases permeability of the cell to b-galactosides. The a gene encodes a transacetylase. ...
- The repressor of the operon is synthesized from the i gene. ...
