Characterization of doublesex and nanos genes in Acropora millepora
… in the upstream regulatory region and introns. nanos plays crucial roles in abdominal formation and proper germline differentiation in Drosophila. Lower animals including sponges and cnidarians also have nanos homologs. To know the roles of nanos genes in the germline speciation in coral, I …

Germline development in Platynereis dumerilii and its connection to embryonic patterning
… molecular germline markers, including vasa, nanos and par-1. This analysis revealed that the primordial germ cells originate from the mesodermal lineage and emerge during the final stages of larval development from a region of undifferentiated cells, namely the posterior growth zone. In …

Dissecting the molecular mechanisms of germ cell development in the planarian Schmidtea mediterranea
… germ cell marker and germ granule component nanos and showed that it is required for planarian germline development, maintenance, and regeneration. Then we took a microarray analysis approach to identify planarian germ cell-specific transcripts and validated their expression in planarian …

The Role of Cyclin E In Pkc Iota-Driven Early Ovarian Tumorigenesis
<p>Among the gynecologic malignancies, epithelial ovarian tumors are the leading cause of death. For the past few decades, the only treatment has involved surgical resection of the tumor and/or general chemotherapies. In an attempt to improve treatment options, we have shown that several oncogenes …

Characterization of Factors Controlling Germline Stem Cell Maintenance in Drosophila Melanogaster
… the translational repression mediated by Pumilio-Nanos (Pum-Nos) complexes. Repression of Pum-Nos activity by Bam-Bgcn complexes permits CB differentiation, presumably through the derepression of CB-promoting mRNAs. In this study, I investigated the transcription- and translation-dependent …

THE IMPACT OF MANAGERIAL OVERCONFIDENCE AND INVESTOR SENTIMENT ON BIDDERS’ ABNORMAL RETURNS
The main objective of this thesis is to investigate takeover gains for UK bidding firms and offer a behavioural approach to empirical analysis. The main issues and key findings of the three empirical chapters are summarised as follows. Chapter 3 empirically investigates the hubris hypothesis for …

Liver fluke development: a target for parasite control?
Fasciolosis, a debilitating disease caused by flatworm parasites belonging to the genus Fasciola, is a prominent threat to global food security due to its widespread infection of agriculturally significant ruminants. Recent studies have identified a population of proliferative cells within Fasciola …
