Developing Zebrafish As An In Vivo Model To Screen Compounds For Anti-Cancer Activity In Human Breast Cancer, Trisha Dhawan
Developing Zebrafish As An In Vivo Model To Screen Compounds For Anti-Cancer Activity In Human Breast Cancer, Trisha Dhawan
Electronic Theses and Dissertations
Breast Cancer (BC) is the most frequently diagnosed cancer; 1:8 women are at risk of developing BC in her lifetime. Cancer metastasis causes the majority of deaths in BC patients. Moreover, side effects of traditional chemotherapeutic drugs (TCD) impair the quality of life of these patients. Discovery and development of safe and effective new therapies is imperative for the treatment of BC and targeting metastasis. The goal herein is to further expand the applicability of in vivo xenotransplantation of human BC cells in transgenic zebrafish to screen potential chemotherapeutics for toxicity and efficacy. For xenotransplantation, MCF-7, BT-474, and MDA-MB-231 BC …
Characterizing The Developmental And Reproductive Toxicities Of Cannabidiol And Δ9-Tetrahydrocannabinol, Dennis Ray Carty
Characterizing The Developmental And Reproductive Toxicities Of Cannabidiol And Δ9-Tetrahydrocannabinol, Dennis Ray Carty
Electronic Theses and Dissertations
Medical marijuana is legal in twenty-nine of the United States and an additional nineteen states have passed legislation for cannabidiol (CBD) treatment of drug-resistant epilepsy, such as Dravet Syndrome (DS) which is diagnosed in children as young as two months. While CBD has shown anecdotal and recently clinical trial efficacy in reducing seizure frequency in DS patients, little is known about the potential adverse side-effects on child physiology, brain development, adult disease, or subsequent generations. Moreover, CBD is rarely administered without including low concentrations of Δ9-tetrahydrocannabinol (THC). The goal of this project is to characterize the relative morphological, behavioral, reproductive, …
Effects Of Benzo[A]Pyrene And Cyp19a1b Knockdown On Zebrafish Development, Khalid M. Alharthy
Effects Of Benzo[A]Pyrene And Cyp19a1b Knockdown On Zebrafish Development, Khalid M. Alharthy
Electronic Theses and Dissertations
Benzo[a]pyrene (BaP) is a ubiquitous environmental contaminant that is both an endocrine disruptor and a carcinogen. Aromatase (CYP19) is a key enzyme in steroidogenesis playing a key role in the hypothalamus-pituitary-gonad feedback loop. We hypothesized that BaP would negatively impact cyp19a1b expression in zebrafish, in turn, adversely affecting development and physiology. Here, we consider whether the toxicities observed following BaP exposure are comparable to those following a transient morpholino (MO)-mediated CYP19a1b knockdown or exposure to an aromatase inhibitor (fadrozole) during early development. One-cell zebrafish embryos were injected with a CYP19a1b-MO or control-MO. Other non-injected embryos were exposed to nominal waterborne …
