Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

A disorder of iron metabolism characterized by a triad of HEMOSIDEROSIS; LIVER CIRRHOSIS; and DIABETES MELLITUS. It is caused by massive iron deposits in parenchymal cells that may develop after a prolonged increase of iron absorption. (Jablonski's Dictionary of Syndromes & Eponymic Diseases, 2d ed)
An excessive accumulation of iron in the body due to a greater than normal absorption of iron from the gastrointestinal tract or from parenteral injection. This may arise from idiopathic hemochromatosis, excessive iron intake, chronic alcoholism, certain types of refractory anemia, or transfusional hemosiderosis. (From Churchill's Illustrated Medical Dictionary, 1989)
Forms of hepcidin, a cationic amphipathic peptide synthesized in the liver as a prepropeptide which is first processed into prohepcidin and then into the biologically active hepcidin forms, including in human the 20-, 22-, and 25-amino acid residue peptide forms. Hepcidin acts as a homeostatic regulators of iron metabolism and also possesses antimicrobial activity.
Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.

- and Paraurostyla weissei) and trace the natural history of DNA rearrangements in this gene in six species, including three previously studied oxytrichids. (jove.com)
- Comparisons of homologous coding regions between earlier and later diverging species provide evidence for fusion of scrambled germ line fragments as small as 24 bp during evolution, as well as simultaneous fragmentation and scrambling of the germ line locus and shifting of the boundaries between coding and noncoding DNA, leading to distinct gene architectures in each species.

- Two different copies of the ITS2 region were identified in the same isolate within some of the species in Fusarium section Liseola ( 25 , 37 ), and a reliable diagnostic technique based on these sequences could not be developed. (asm.org)
- 26 ) used the DNA sequences of the nuclear rDNA large subunit, mitochondrial small subunit, and β-tubulin to develop a phylogeny that includes 36 taxa in the G. fujikuroi species complex. (asm.org)
- Alternative regions such as the histone and β-tubulin genes might be used more effectively. (asm.org)
- During the past 12 years, there has been rapid development of genome-editing strategies that make it possible to directly target regions of genes in a DNA sequence-specific manner. (plantphysiol.org)
- Additionally, we screened non-coding regions of the gene that are usually not investigated. (bmj.com)
- Finally, mutations in exon 5N and in untranslated regions of the SCN1A gene that were conserved during evolution were excluded in the remaining negative patients. (bmj.com)
- Altogether, these findings widely expand the SCN1A mutations spectrum identified and highlight the importance of screening the coding regions with both direct sequencing and a quantitative method. (bmj.com)
- This probably leads to selection against most slippage-prone sequences in coding regions. (biomedcentral.com)
- their sequences are often conserved and are often encoded in regions of open chromatin. (scienceblogs.com)

- PanArray is an oligonucleotide probe selection algorithm for tiling multiple genome sequences using a minimal number of probes. (biomedcentral.com)
- Three conserved cis -regulatory elements within the promoter, E1, A3, and RIPE3b/C1, respectively, appear to be indispensable for proper insulin gene regulation ( 22 , 25 ). (asm.org)
