Oct4 and Sox2 regulate methylation at the Igf2/H19 imprinting control region
… parental-specific methylation of an imprinting control region (ICR). Although CTCF sites maintain the absence of DNA methylation on maternal ICRs after fertilization, some Beckwith-Wiedemann patients showed maternal ICR methylation that correlated with mutations in one of the pair of octamer …

THE INTERACTION OF TRANSCRIPTION FACTORS WITH THE LONG CONTROL REGION OF HPV 16
… bp circular DNA genome of HPV 16 termed the long control region (LCR) does not contain genes but contains the control elements for transcriptional activation and probably replication of the virus. Research done in our lab previous to the work towards this thesis showed that transcriptional …

Application of a DNA Mini-Barcoding System based on the Mitochondrial Control Region for the Identification of Raw and Processed Tuna Products
… mini-barcoding system based on the mitochondrial control region (CR). A total of 80 samples of raw, dried, and canned tuna products were collected at the retail level for CR mini-barcoding analysis. The samples underwent DNA extraction, polymerase chain reaction (PCR), and DNA sequencing of the …

Protein -Dna Interactions Required for Regulation of the Proline Utilization Operon in Salmonella
… (SELEX) approach was used to enrich for put control DNA molecules defective in PutA binding in vitro. These experiments identified nucleotide residues that may be important for the specificity of the PutA-put control region interaction. Using the lambda Red system, the wild-type put control …

Phylogeographic analysis reveals strong geographical structuring in the klipspringer, Oreotragus oreotragus
… of the 11 subspecies designations. Mitochondrial control region and cytochrome b sequence data were used to investigate these topics using blood, faecal and museum specimens. Cytochrome b and control region fragments were amplified in 83 and 60 samples respectively, out of a total sample set of 89 …

Das "Nürnberger Bündnis gegen Depression"
… in comparison to a baseline-year (2000) and a control region (Wuerzburg). Results: The results for the first year of intervention (2001) show a significant decrease of suicidal acts in Nuremberg compared to the baseline and to the control region. Suicidal acts dropped from 620 cases to 500 …

Phylogeographic structure of the Atlantic pupfish, Cyprinodon variegatus (Cyprinodontidae), along the eastern coast of North America: Evidence from mitochondrial nucleotide sequences
… genetic sequence structure of the mitochondrial control region (D-loop, non-coding origin of replication) and cytochrome-b gene for evidence of northern and southern subspecies within the Atlantic Coast of the eastern United States. Additionally, it will be may be possible to determine if …

Regulation of the glpFK operon of Escherichia coli K-12 and characterization of it gene products
… between the two genes were determined. The control region for the glpFK operon was identified and sequenced. The gipK gene product was purified to near homogeneity by streptomycin sulfate and ammonium sulfate fractionation with subsequent DEAE Sephadex chromatography. N-terminal amino acid …

Comparative phylogeography as an integrative approach to understand human and other mammal distributions in Europe.
… done by collecting published mitochondrial DNA control region sequences of 29 different species and analysing them individually and comparatively. This research presents a standardised way of understanding phylogeography from the mitochondrial DNA perspective to improve the comparison of studies …

Gene Flow and Dispersal Among Populations of the Stonefly <i>Peltoperla tarteri</i> (Plecoptera: Peltoperlidae) in the Southern Appalachians
… stream insect dispersal. In this study, the control region of mitochondrial DNA was used to study gene flow and dispersal among populations of the stonefly <i>Peltoperla tarteri</i> in the Southern Appalachians. The control region of <i>P. tarteri</i> is approximately 1270 base pairs (bp) in …

Morphometric and genetic variation among populations of the southern short-tailed shrew, Blarina carolinensis, located along the Coastal Plain of Virginia
… molecular genetic characters (mitochondrial DNA control region and exon-primed intron-crossing nuclear DNA, EPIC) from peninsular populations of B. carolinensis and compared them to shrews of the mainland population to address this question. The sources of specimens were shrews ensnared in …

A Biclustering Approach to Combinatorial Transcription Control
Combinatorial control of transcription is a well established phenomenon in the cell. Multiple transcription factors often bind to the same transcriptional control region of a gene and interact with each other to control the expression of the gene. It is thus necessary to consider the joint …

Resting-State Functional Brain Networks in Bipolar Spectrum Disorder: A Graph Theoretical Investigation
… of BSD stems from disrupted prefrontal control over subcortical limbic structures (Strakowski et al., 2012; Depue & Iacono, 1989). However, existing neuroimaging research on functional connectivity between frontal and limbic brain regions remains inconclusive, and is unable to adequately …
