The Hippo pathway is a master regulator of cell proliferation and organ size, namely through regulation of transcriptional co-activators YAP and TAZ which bind TEAD1-4 transcription factors. The Hippo effector YAP is dysregulated in many human solid tumours including rhabdomyosarcoma and oesophageal cancer. Additionally, persistent hyperactivity of YAP in activated but not quiescent satellite cells can give rise to embryonal rhabdomyosarcoma. However, the question of exactly how YAP acts as an oncogene and actively gives rise to tumour progression in these cancers remains unknown. In this thesis I characterised the mechanisms which determine the functional role of YAP in driving instability in the genome. Secondly, lentiviral mediated knockdown of YAP is performed to determine and investigate its effect on tumorigenesis. Thirdly, gene sets from constitutive YAP S127A induced mouse ERMS tumours subjected to array-CGH were further analysed. Finally, I cloned chicken Yap1, Tead1 and Fstl5 to identify its role during chick embryonic development, by the retroviral mediated loss of function approach. The results demonstrated that constitutive YAP S127A expression in-vitro as well as in-vivo induces chromosomal instability by increasing the rate of mitotic chromosome segregation errors and copy number alterations of oncogenes and other cancer related genes. Recurrent copy number gains of the p53 inhibitor Mdm2 were observed in YAP S127A-driven ERMS tumours. Moreover, lentiviral mediated YAP knockdown showed significant reduction in proliferation, migration and invasion as well as transformation potential in human cultured cancer cells. Moreover, retroviral YAP S127A expression during early stages of chick embryo development did not lead to an overt phenotype and showed poor survival. Additionally, I have cloned RCAS-RNAi vectors to study the loss of function effect on Hippo targets and Fstl5 during chicken embryo development. Collectively, my data provides insight into the mechanisms with which YAP could drive tumorigenesis and that YAP knockdown can be considered a potential therapeutic target to reduce cancer progression.

Agency and communion are fundamental dimensions underlying psychological processes. Although agency and communion are coherent dimensions, their origins, nature, stability differ across theoretical framework. Common to these frameworks are gender differences in agency and communion. The present study hypothesized that because agency and communion relate to gender, they may also relate to digit ratio. The present study is important because digit ratio may offer clues on the origins and nature of agency and communion, and their gender differences. Agency and Communion factors were extracted from implicit linguistic measures obtained by LIWC analysis of selfnarratives. Exploratory structural equation modeling indicated communion related to digit ratio in men, and gender differences in communion. Although the results supported the distal, biological influences of communion argued by evolutionary accounts, the null finding agency was not related to digit ratio, while not directly interpretable, did not contradict socialization accounts of agency. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection
