Zebrafish (Danio rerio) have become an increasingly important model organism for cancer research. There are several cancer models in which neoplasms are induced chemically or genetically. However, spontaneous (unknown etiology) neoplasms are rather common in zebrafish, particularly in older fish. For over a decade, spontaneous intestinal neoplasia and preneoplastic intestinal...
Fanconi's Anemia (FA) is an autosomal recessive chromosomal instability disorder. The
symptoms include congenital abnormalities, defective hematopoiesis (formation of cells
of the blood), and high risk of developing acute myeloid leukemia and solid tumors.
Fanconi researchers have long been puzzled by how Fanconi Anemia (FA) cells, which
are known to...
Background
Bcl11b, previously CTIP2, is a zinc finger nuclear transcription factor involved in the development of keratinocytes, teeth, T lymphocytes, and nervous tissue. Expression of Bcl11b has been reported in human head and neck squamous cell carcinoma (HNSCC) and increased expression correlates with poorly differentiated tumors. This study aimed to...
Throughout most of the developed world, surgical sterilization via gonadectomy has become a common tool for combating the overpopulation of unwanted dogs as well as to eliminate the risk of reproductive diseases in pet dogs. In the dog as in other normal adult mammal, the hypothalamus secretes gonadotropin-releasing hormone (GnRH),...
A foundation for the control of tumors is presented,
based upon the formulation of a realistic, knowledge-based
mathematical model of the interaction between tumor cells
and the immune system. The parametric control variables
relevant to the latest experimental data, e.g., the sigmoidal
dose-response relationship and Michaelis-Menten dynamics,
are also considered....
Zebrafish (Brachydanio rerio) are small, freshwater teleost fishes in the family
Cyprinidae, the true minnows. They are native to the tropical latitudes of India, but
have become widespread through their use as aquarium fish and as models for several
branches of biological research. Their ease of rearing, short generation time,...
A digoxigenin-labeled nonradioactive detection system was used
to screen a zebrafish cDNA library for p53-like and ras-like genes.
One clone was isolated and identified as an incomplete p53-like
gene. The insert size of this clone is 1777 bp, which encodes part of
evolutionarily conserved region II and all of regions...
We are developing a flavin-containing (Fmo) knock-out mouse for Fmo2 that will be utilized to elucidate the role of active human FMO isoform 2 (FMO2.1) in xenobiotic metabolism and toxicity. Since FMO2 is primarily expressed in lung this will provide information on how 27% of African-Americans and 5% of Hispanics...
This thesis presents a method for determining range
of body motion for a walking machine with feet fixed on
the ground. The darkling beetle was selected as the
sample subject in this study.
A closed form inverse kinematic solution is used to
determine if a point in space is within...
