Role Of Cyp2a5 In Drug Metabolism, Chemical Toxicity, And Maintenance Of Steroid Hormone Homeostasis : Insights From Studies On A Novel Cyp2a5-Null Mouse Model, Xin Zhou
Legacy Theses & Dissertations (2009 - 2024)
The central hypothesis is that CYP2A5 plays an important role in the metabolism of xenobiotic substrates, and in the toxicity induced by over-exposure to drugs, as well as in the metabolism of endogenous compounds and regulation of steroid hormone homeostasis. The specific aims are: 1) to generate and characterize a Cyp2a5-null mouse; 2) to determine the role of CYP2A5 in the systemic clearance of nicotine and cotinine; and 3) to explore the mechanisms underlying the resistance of the lateral nasal gland (LNG) of male Cyp2g1-null/Cyp2a5-low mouse and Cyp2a5-null mouse to acetaminophen (AP) toxicity.
An Rnai Screen Targeting The Protein Tyrosine Kinases Identifies Bruton's Tyrosine Kinase (Btk) As A Breast Cancer Cell Survival Factor, Cheryl Lynne Eifert
An Rnai Screen Targeting The Protein Tyrosine Kinases Identifies Bruton's Tyrosine Kinase (Btk) As A Breast Cancer Cell Survival Factor, Cheryl Lynne Eifert
Legacy Theses & Dissertations (2009 - 2024)
The receptor protein tyrosine kinases (RPTKs) and the non- receptor protein tyrosine kinases (PTKs) are among the most commonly up-regulated genes found in all types of cancers. Although, a large body of data implicates a majority of tyrosine kinases (TKs) in cancer, few have been extensively evaluated for any potential therapeutic benefit in any of the many subtypes of breast cancer. We have used RNA interference (RNAi) to perform a large-scale loss-of-function analysis to facilitate the identification of individual factors necessary for the survival of an ErbB2 positive breast cancer cell line. We have found that 30% of the TKs …
Proactive Procreation : Ethical Implications Of New Genetic Technologies For Parental Obligations To Future Offspring, L Syd M. Johnson
Proactive Procreation : Ethical Implications Of New Genetic Technologies For Parental Obligations To Future Offspring, L Syd M. Johnson
Legacy Theses & Dissertations (2009 - 2024)
This dissertation examines the ethical implications of recent genetic innovations, particularly preimplantation genetic diagnosis, for the obligations and duties of parents to future children. I critique common but uncompelling objections to the use of genetic information, diagnosis, and technology to influence the characteristics of future offspring, and conclude that genetic selection and enhancement are not different in kind or degree from other means of selection, direction, and enhancement that parents engage in to shape the lives of their children. Procreation is morally risky -- it risks imposing substantial burdens on persons who would not otherwise have to bear those burdens, …
