Clinical record In December 2012, a 30-year-old man was admitted via the emergency department of our tertiary hospital with atrial fibrillation (AF), new-onset biventricular cardiac failure, acute renal failure and elevated liver function test results. He presented with a 2-week history of dyspnoea, palpitations and epigastric discomfort. An electrocardiogram confirmed AF with a rapid ventricular response, and he was subsequently admitted to hospital. His initial heart rate varied between 120 and 140 beats/min and his blood pressure was 140/90 mm Hg. He had distended jugular veins and cardiac examination revealed a gallop rhythm and an apical pansystolic murmur. His lungs were clear to auscultation and he had no peripheral oedema. The patient was a successful bodybuilder and strongman. By default, all articles on Green Med are sorted based on the content type which best reflects the data which most users are searching for.

Metoprolol side effects mayo clinic Zoloft 25 mg The tamoxifen-inducible Cre strain, B6. Cg-TgCAG-cre/Esr15Amc/J 004682, is used to conditionally delete floxed sequences throughout the. Inducible Cre These constructs require the addition of an exogenous ligand e.g. tamoxifen to activate Cre. One advantage of this system is tight temporal. Efficient Recombination in Diverse Tissues by a Tamoxifen-Inducible Form of Cre A Tool for Temporally Regulated Gene Activation/Inactivation. The Cre-lox system is one of the most revolutionary tools in the geneticist's toolbox. You don't have to be a user or developer of cre or floxed mice to appreciate the impact that cre-lox technology has had on biomedical research and genetic engineering. Since its discovery in the early 1980's and its subsequent use in the mouse in the early 1990's, it has become known as the most sophisticated method of manipulating the mouse genome. Despite its widespread use, Cre-lox strains may not behave exactly as some researchers expect, and they can be used in some very creative ways. Cre activity can vary depending if transgene is inherited from the male or female parent. FVB-Tg(EIIa-cre)C5379Lmgd/J (003724), converts floxed alleles to complete knockout alleles because Cre is expressed throughout the mouse, but it is significantly more efficient when transmitted maternally. Cg-Tg(Camk2a-cre)T29-1Stl/J (005359), recombine sequences in the hippocampus, but there is expression in male germ cells as well. The parental inheritance pattern may not matter for all Cre strains, but it is a good idea to compare results obtained from both maternal and paternal transmission whenever possible. Cre is often expressed from a randomly integrated transgene, but very few insertion sites are known. In recent years, the Cre integrase from bacteriophage P1 has become an essential tool for conditional gene activation and/or inactivation in mouse. In an earlier report, we described a fusion protein between Cre and a mutated form of the ligand binding domain of the estrogen receptor (Cre-ER is ubiquitously expressed to permit temporally regulated Cre-mediated recombination in diverse tissues of the mouse at embryonic and adult stages. We demonstrate that a single, intraperitoneal injection of TM into a pregnant mouse at 8.5 days postcoitum leads to detectable recombination in the developing embryo within 6 h of injection and efficient recombination of a reporter gene in derivatives of all three germ layers within 24 h of injection. In addition, by varying the dose of TM injected, the percentage of cells undergoing a recombination event in the embryo can be controlled. Dose-dependent excision induced by TM was also possible in diverse tissues in the adult mouse, including the central nervous system, and in cultured cells derived from the transgenic mouse line. This inducible Cre system will be a broadly useful tool to modulate gene activity in mouse embryos, adults, and culture systems where temporal control is an important consideration.

Indeed, one major limitation of using tamoxifen in vivo may be its toxicity. Inducible Gene Expression and Gene Modification in Transgenic Mice.. Efficient Recombination in Diverse Tissues by a Tamoxifen.. Inducible Cre mice. - NCBI. Inducible DNA recombination of floxed alleles in vivo by liver metabolites of tamoxifen TAM is an important tool to study gene functions. Here.
