Infertility is a common problem, affecting approximately 10% of all couples attempting to conceive (Watson et al., 1998). Although numerous potential causes of human infertility exist, many cases are thought to have genetic etiologies, including...
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...
The pairing and recombination of homologous regions of the X and Y chromosomes, in an area known as the pseudoautosomal region (PAR), has been a phenomenon of interest since its discovery in 1934. Its presence seems to be limited to eutherian...
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...
The prophage of bacteriophage P1 is a unit copy plasmid, stable in Escherichia coli during cell division due to its partition system. The active P1 partition system consists of two genes, parA and parB, and a cis-site, parS. ParS contains all of...
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...
During the last decade, new technologies created a deluge of potential drug targets. Sifting through thousands of potential drug targets is a major industry bottleneck. Pharmaceutical companies can save billions of dollars by identifying most...
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...
Minor histocompatibility (H) antigens are typically identified as barriers to transplantation in graft exchange experiments between major histocompatibility complex (MHC)-matched hosts (Bailey 1975; Snell and Bunker 1960). This approach has allowed...
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). ...
Considering the pleiotropic manifestations of the rare, inherited, bone marrow failure disease, Fanconi Anemia, afflicted patients must be evaluated and monitored by specialty physicians (such as dermatologists, opthamologists, gastroenterologists,...
DNA -- Analysis; Nucleotide sequence; Cancer genes
The first methods for sequencing DNA were developed in the mid-1970’s (Strausberg et al. 2008). The sequencing efforts were labor-intensive, slow, and costly (Metzker, 2005). As a result, researchers could sequence only a few base pairs per...
The mouse frizzy (fr) mutation is a Mendelian recessive trait that affects hair structure and formation in mice. The mutation arose in a mouse of mixed origin at the Jackson Lab (Bar Harbor, ME) in 1951. Frizzy is known to be linked to other genes...
The intent of this research project was to purify the Shigella flexneri virulence plasmid without the use of ultra-centrifugation. The ultra-centrifugation is the most commonly used technique; however the PFGE has proven to isolate the plasmid...
The tick has ability to transmit a greater variety of infectious agents to humans and other animal species than any other blood-feeding arthropod. Feeding over a period of days induces specific host hemostatic, inflammatory, and immune responses....
