Abstract:
Heterozygous mutations and deletions of the gene that encodes the transcription factor hepatocyte nuclear factor 1β (HNF1B) are the commonest known monogenic cause of developmental kidney disease. However, diagnosis remains challenging due to phenotypic variability and frequent absence of a family history. There is also no consensus as to when HNF1B genetic testing should be performed. This thesis includes work looking at the identification of HNF1B-associated disease. An HNF1B score was developed in 2014 to help select appropriate patients for genetic testing. The aim in chapter 2 was to test

Abstract:
Primary human hepatocytes are a scarce resource with variable function, which diminishes with time in culture. As a consequence their use in tissue modelling and therapy is restricted. Human embryonic stem cells (hESCs) could provide a stable source of human tissue due to their properties of self-renewal and their ability to give rise to all three germ layers. hESCs have the potential to provide an unlimited supply of hepatic endoderm (HE) which could offer efficient tools for drug discovery, disease modelling and therapeutic applications.

The nuclear receptor Hepatocyte Nuclear Factor 4a (HNF4a; NR2A1) regulates the transcription of many genes involved in glucose and lipid metabolism.

The aim of this study was to investigate the regulation of target genes in the metabolic pathways of glycolysis, lipogenesis and gluconeogenesis by HNF4a.

Abstract:
The UDP-glucuronosyltransferases (UGTs) are a superfamily of enzymes that glucuronidate small, lipophilic molecules, thereby altering their biological activity and excretion. In humans, important examples of UGT substrates include molecules of both endogenous and xenobiotic origin; thus, UGTs are considered essential contributors to homeostatic regulation and an important defence mechanism against chemical insult. In keeping with both roles, UGTs are most strongly expressed in the liver, a predominant organ involved in detoxification. Rates of glucuronidation in humans are neither uniform amon

Abstract:
My first project was to investigate the role of Hepatocyte Nuclear Factor 1 (HNF1) and Nuclear Factor I (NFI) on alpha-fetoprotein (AFP) promoter activity during liver development. AFP is highly expressed in the fetal liver, silenced at birth, and remains at very low levels in the adult liver. A GA substitution located at -119 of the human AFP promoter is associated with hereditary persistence of AFP (HPAFP) expression in the adult liver (Hum Molec Genet, 1993, 2:379). The -120 region harbors overlapping binding sites for HNF1 and NFI. While it has been shown that the GA substitution increas

Mouse primary hepatocyte cultures were used as the main model system together with cell and molecular biology methods.

The overall objective of this research was to understand the mechanims by which growth hormone (GH) regulates insulin-like growth factor-I (IGF-I) gene expression in liver. Previous studies have suggested that GH regulation of IGF-I gene expression in liver is mediated by binding of the transcription factor signal transducer and activator of transcription (STAT) 5 to four binding sites located distantly from the IGF-I promoter. The first specific objective of this research was to determine whether additional STAT5 binding sites were involved in GH stimulation of IGF-I gene expression in liver.
