Conditional gene knockout is a technique used to eliminate a specific gene in a certain tissue, such as the liver. [ 1 ][ 2 ] This technique is useful to study the role of individual genes in living organisms. It differs from traditional gene knockout because it targets specific genes at specific times rather than being deleted from beginning ...
The term "floxing" is a portmanteau constructed from the phrase "flanking/flanked by LoxP". The floxing method is essential in the development of scientific model systems as it allows researchers to have spatial and temporal alteration of gene expression. [ 2 ] The Cre-Lox system is widely used to manipulate gene expression in model organisms ...
Cre recombinase is a tyrosine recombinase enzyme derived from the P1 bacteriophage. The enzyme uses a topoisomerase I -like mechanism to carry out site specific recombination events. The enzyme (38 kDa) is a member of the integrase family of site specific recombinase and it is known to catalyse the site specific recombination event between two ...
A conditional gene knockout allows gene deletion in a tissue in a tissue specific manner. This is required in place of a gene knockout if the null mutation would lead to embryonic death, [12] or a specific tissue or cell type is of specific interest. This is done by introducing short sequences called loxP sites around the gene.
Gene knock-in originated as a slight modification of the original knockout technique developed by Martin Evans, Oliver Smithies, and Mario Capecchi.Traditionally, knock-in techniques have relied on homologous recombination to drive targeted gene replacement, although other methods using a transposon-mediated system to insert the target gene have been developed.

In 2013, two conditional knockout mouse models, called Dhh-Cre;Nf1 flox/flox [45] (which develops neurofibromas similar to those found in NF1 patients) and Mx1-Cre;Nf1 flox/flox [46] (which develops myeloproliferative neoplasms similar to those found in NF1 juvenile myelomonocytic leukemia/JMML) were used to study the effects of the specific ...
Directions. Place a rack in center of oven; preheat to 350°. Grease a 9" springform pan with cooking spray. In a food processor, pulse cookies, brown sugar, and salt until fine crumbs form. Add ...
CREB-binding protein, also known as CREBBP or CBP or KAT3A, (where CREB is cAMP response element-binding protein) is a coactivator encoded by the CREBBP gene in humans, located on chromosome 16p13.3. [ 5 ][ 6 ] CBP has intrinsic acetyltransferase functions; it is able to add acetyl groups to both transcription factors as well as histone lysines ...
