Depression is characterized by a mood and behavior, that can affect the ability of
a person to perform daily activities and interact with others. Depression is an illness that
can be caused by biochemical and environmental changes. Chemical...
Ahearn et al. (J. Heredity 93:210-213) have previously shown that the rat fuzzy and Charles River "hairless" mutations are defects in the same gene on rat Chromosome 1, and are likely orthologues of mouse frizzy (abbreviated fr) on mouse Chromosome...
During the development of potential protein or antibody therapeutics in a pharmaceutical environment, the use of animal models as test subjects is a necessary requirement. The dosing of mice, rats, and primates is essential to drug development...
Discovering RNA editing sites in model organisms provides an insight into their adaptations in addition to finding potential sites for gene expression regulation. In this study, we focused on the grin1b gene of Zebrafish due to its important...
Comfrey is an herb traditionally used for bone healing. It is also sold as a dietary supplement to promote respiratory health. Comfrey has been banned in Canada and Germany because of its link to liver damage or failure, but remains legal in the...
Myogenesis is an important process that occurs during the developmental stages of an embryo. Stem cells learn of their fate during this course if they will become muscle cells and from there, differentiation within those muscle cells will take...
Cyclin D1 is the major regulator of cell cycle --- the division of cells to copy themselves. Cyclin D1 is the product of ccnd1 gene and plays an important role in regulation of cell cycle transition from G1 phase to S phase. The cell cycles of...
Frizzy (fr) is a spontaneous recessive mutation in mice characterized by curly vibrissae, a disheveled coat and short hair (Snell 1951). Previous linkage analysis located the mutant fr allele on Mus musculus Chromosome 7 (Falconer and Snell 1952)....
A-to-I RNA editing is an enzymatic reaction commonly found in the nervous system of various organisms. The mechanism behind this post-transcriptional modification is the hydrolytic deamination of Adenosine to Inosine by a family of enzymes known as...
The ability of embryonic stem cells to give rise to all cells comprising the three germ layers – endoderm, mesoderm and ectoderm – highlights a powerful in vivo system for the study of early embryonic development. Human embryonic stem cell...
Receptor-mediated endocytosis as a route of gene delivery shows promise as it is a natural cellular process and allows targeting of ligands to specific cells. A carrier system consisting of two important components: a targetable ligand,...
The recessive male sterility and histoincompatibility mutation (mshi) in the mouse generates pleiotropic effects on graft transplantation and male reproduction. Previous analysis of backcross mice using a large set of microsatellite markers has...
The male sterility and histoincompatibility mutant, mshi, results from a recessive mutation that arose spontaneously in the BALB/cBy inbred mouse strain. Using a 402-member BALB/cBy-mshi/mshi (BALB/cBy-mshi C57BL/6J) F1 backcross panel, the...
Recent physiological investigations examining the cardiac calcium handling abilities of tuna and rainbow trout suggest increased reliance on sarcoplasmic reticulum calcium contribution for heart contractility that is both temperature and frequency...
The mouse frizzy (fr) mutation arose on a genetically mixed background and was first described by G.D. Snell of The Jackson Laboratory in 1951. Mice carrying this recessive mutation have curly vibrissae which can be observed as early as one to two...
Parental behavior in animals; Rats -- Physiology; Animal mutation
Rats that are hypotrichotic (lacking normal hair) due to the autosomal recessive
shorn (shn) mutation showed a low survival rate in brother by sister matings in a breeding
colony of SU/Csu rats. The majority of rats died before weaning. Subsequent...
The discovery of antibiotics was one of the greatest discoveries of the 21st 20th century (Van Kraaig, 1999 and Livermore, 2004). The current need for new antibiotics to fight bacterial pathogens that have become resistant is growing every day. ...
The frizzy (fr) mutation in Mus musculus affects hair structure and formation. Early studies demonstrated that the gene responsible for frizzy assorts to mouse Chromosome 7 along with pink-eyed dilution (p), chinchilla (cch), and shaker-1 (sh-1). ...
The RNA molecule is responsible for providing information to the cell to assemble proteins specified by the DNA. A specific type of RNA editing can convert individual adenosines into inosine by an enzyme called adenosine deaminase acting on RNA...
RNA editing is a mechanism which is used to increase the number of possible protein products from a specific gene. The catalytic enzymes for RNA editing are known to be present in a wide variety of organisms, including many different insects. It...
