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 …
