  1. Wellcome Trust Centre for Gene Regulation and Expression

    The Wellcome Trust Centre for Gene Regulation and Expression , located within the University of Dundee , pioneers new approaches in the field of gene expression and chromosome biology. Previously part of the Dundee Biocentre and receiving significant Wellcome Trust funding from 1995 onwards, it was awarded Wellcome Trust Centre status in 2008. Professor Angus Lamond is the Centre s Director. The Centre aims to enhance our understanding of how genes are regulated at both the single cell and whole organism level. Researchers use a wide range of advanced techniques, including live cell fluorescent imaging disambiguation needed date November 2011 and mass spectrometry based proteomics , to explore the functions of key proteins and molecular mechanisms in cell biology. Research and discoveries Live cell imaging and proteomic studies have allowed researchers at the Centre to gain fresh understanding of protein function and cell behaviour. The Centre is studying many aspects of the cell cycle , including the way in which chromosomes replicate and separate during cell division and how DNA damage is detected. Failure of these events can lead to major faults within a genome , potentially leading to the rise of cancerous cells. The Centre is also investigating how DNA is tightly wound and compacted so that it can fit into the nuclei of eukaryotic cells, as well as the protein DNA complexes that are involved in this packaging. The controlled unravelling of DNA is an important step in the regulation of gene function.

  1. Gene expression programming

    Gene Expression Programming GEP is an evolutionary algorithm that evolves populations of computer program s in order to solve a user defined problem. GEP has similarities, but is distinct from, the evolutionary computational method of genetic programming . In genetic programming the individuals comprising a population are typically symbolic s expression expression trees however, the individuals comprising a population of GEP are encoded as linear chromosome s, which are then translated into s expression expression trees . The important difference is that the recombination operators of genetic programming operate directly on the tree structure e.g. swapping sub trees , whereas the recombination operators of gene expression programming operate directly on the linear encoding i.e. before it is translated into a tree . As such, after recombination, the modified portions of the resulting expression trees often bear little semblance to their direct ancestors. The expression trees are themselves computer programs evolved to solve a particular problem and are selected according to their performance fitness in solving the problem at hand. After repeated iteration, populations of such computer programs will ideally discover new traits and become better adapted to a particular selection environment. The desired endpoint of the algorithm is that a good solution has been evolved by the evolutionary process.

  1. Protein K (gene expression)

    About the nucleic acid binding protein in eukaryotes the bacterial porin Protein K porin Protein K is a human protein found in the cell nucleus that binds to pre messenger RNA mRNA as a component of heterogeneous ribonucleoprotein particle s. The simian homology biology homolog is known as protein H16 . Both proteins bind to single stranded DNA as well as to RNA and can stimulate the activity of RNA polymerase II , the protein responsible for most transcription genetics gene transcription . The relative affinities of the proteins for DNA and RNA vary with solution conditions and are inversely correlated, so that conditions promoting strong DNA binding result in weak RNA binding. ref name Gaillard Gaillard C, Cabannes E, Strauss F. 1994 .

  1. Regulation T

    Federal Reserve Board Regulation T also referred to as Reg T is 12 CFR 220 Code of Federal Regulations, Title 12, Chapter II, Subchapter A, Part 220 Credit by Brokers and Dealers . ref name FRB http www.federalreserve.gov regulations default.htm t Federal Reserve Website ref Regulation T governs the extension of credit by securities brokers and dealers in the United States. ref name FRB Its best known function is the control of Margin finance margin requirements for stocks bought on margin. The initial margin requirement for such margin stock purchases is 50 , ref http ecfr.gpoaccess.gov cgi t text text idx?c ecfr&sid 40cc031a4a064ca8d3f500270b0d0fd7&rgn div8&view text&node 12 3.0.1.1.1.0.1.12&idno 12 Text of 12 CFR 220.12 ref and has been since 1974, ref http findarticles.com p articles mi m3937 is 2000 Sept Oct ai 80855422 pg 2 Fortune, Peter, Margin Requirements, Margin Loans, and Margin Rates Practice and Principles , New England Economic Review , Sept Oct. 2000 ref but Regulation T gives the Federal Reserve the authority to change that percentage. Raising the margin requirement ostensibly reduces risk in the financial system by reducing the potential leverage and total buying power of investors. Conversely, lowering the margin requirement ostensibly increases systemic risk by expanding the buying power and leverage available to investors. Since 1974 the Federal Reserve has not deemed it necessary to adjust the margin requirement, despite periodic extremes of price volatility in the equities markets.

  1. Expression cloning

    Unreferenced date October 2007 Expression cloning is a technique in DNA cloning that uses expression vector s to generate a library of clones, with each clone expressing one protein. This expression library is then screened for the property of interest and clones of interest recovered for further analysis. An example would be using an expression library to isolate genes that could confer antibiotic resistance . Expression vectors Expression vectors are a specialized type of cloning vector in which the transcriptional and translational signals needed for the regulation of the gene of interest are included in the cloning vector. The transcriptional and translational signals may be synthetically created to make the expression of the gene of interest easier to regulate. Purpose Usually the ultimate aim of expression cloning is to produce large quantities of specific protein s. To this end, a bacteria l expression Clone genetics clone may include a ribosome binding site Shine Dalgarno sequence to enhance translation of the gene of interest s mRNA, a Transcription genetics transcription termination sequence, or, in eukaryotes , specific sequences to promote the Posttranslational modification post translational modification of the protein product.

  1. Ectopic expression

    Unreferenced date December 2009 Ectopic expression is the expression of a gene in an abnormal place in an organism. This can be caused by a disease, or it can be artificially produced as a way to help determine what the function of that gene is. Ectopic expression of a gene can be done by introducing a transgene with a modified promoter biology promoter into the target organism transient or stable transfection or by using the GAL4 UAS system Gal4 UAS system. Ectopic expression is used to gain further understanding of the gene s functions. References DEFAULTSORT Ectopic Expression Category Gene expression Genetics stub ...   more details
