Repurposing Metformin And Antifolates For The Treatment Of Hepatocellular Carcinoma, Sherouk Mohamed Tawfik
Repurposing Metformin And Antifolates For The Treatment Of Hepatocellular Carcinoma, Sherouk Mohamed Tawfik
Theses and Dissertations
Hepatocellular carcinoma (HCC), one of the most prevalent types of cancers worldwide, continues to maintain high levels of resistance to standard therapy. As clinical data revealed poor response rates, the need for developing new methods has increased to improve the overall wellbeing of patients with HCC. Due to its safety, wide availability and previously reported anti-cancer effects, metformin (MET) serves to be a possible therapeutic agent when combined with other well-known anti-cancer agents. The aim of this study was to investigate the potential anti-cancer effects of MET, an anti-diabetic agent, when combined with two antifolate drugs: trimethoprim (TMP) or methotrexate …

Crosstalk Between Hippo And Rb Tumour Suppressor Pathways In Ovarian Cancer, Fatmata Sesay
Theses and Dissertations
The cell cycle is a highly regulated process that ensures the timely and accurate division of cells. Events of the normal cell cycle fall under two categories - positive and negative regulatory mechanisms. The first category, positive regulatory machinery, includes active protein complexes of cyclins in association with their partnering cyclin-dependent kinases (cyclin/CDK), which mediate series of phosphorylation events that relay a cell cycle progression from one stage to the next. The second category, the negative regulatory mechanisms, include the checkpoint controls consisting of the retinoblastoma (RB) family of proteins, some of which can form a transcriptional repressor complex DREAM. …
Human Papillomavirus 16 E2 Regulates Host Cell Pathways Important For Cancer Progression And Treatment Sensitivity Which May Contribute To Cancer Outcomes, Christian Fontan
Human Papillomavirus 16 E2 Regulates Host Cell Pathways Important For Cancer Progression And Treatment Sensitivity Which May Contribute To Cancer Outcomes, Christian Fontan
Theses and Dissertations
Human papillomaviruses (HPVs) are causative agents in around 5% of all cancers, including cervical and oropharyngeal. A feature of HPV cancers is their better clinical outcome compared with non-HPV anatomical counterparts. In turn, the presence of E2 predicts a better clinical outcome in HPV-positive cancers; the reason(s) for the better outcome of E2-positive patients is not fully understood.
Previously, we demonstrated that HPV16 E2 regulates host gene transcription that is relevant to the HPV16 lifecycle in N/Tert-1 cells. One of the genes repressed by E2 and the entire HPV16 genome in N/Tert-1 cells is TWIST1. In these studies, we demonstrate …
