Molecular Mechanisms Underlying The Early Life Programming Of The Liver, Gurjeev Sohi
Molecular Mechanisms Underlying The Early Life Programming Of The Liver, Gurjeev Sohi
Electronic Thesis and Dissertation Repository
Clinical studies have demonstrated that intrauterine growth restriction (IUGR) offspring, faced with a nutritional mismatch postpartum, have an increased risk of developing the metabolic syndrome. The maternal protein restriction (MPR) rat model has been extensively studied to investigate the adverse effects of a nutritional mismatch in postnatal life of IUGR offspring. Previous studies have demonstrated that MPR leads to impaired function of the liver, an important metabolic organ. However the underlying mechanisms which predispose these offspring to the metabolic syndrome remain elusive. In the following studies, low protein diet during pregnancy and lactation led to IUGR offspring with decreased liver …

Gene therapy has attracted attention in the fields of medicine, pharmacy, and bionanotechnology due to the potential for treating a large number of medically relevant diseases. Oral inhalation (OI) is a promising route for the administration of therapeutics, including small molecules and biomacromolecules, such as nucleotides, peptides, and proteins, to (locally) and through (systemically) the lungs. The use of OI is especially attractive for the delivery of nucleic acids as it provides a direct and non-invasive route for targeting the lungs. Pressurized metered-dose inhalers (pMDIs), are the most commonly used OI in treatment of lung diseases and are thus promising …

Aconitase, the second enzyme of the tricarboxylic acid cycle encoded by ACO1 in the budding yeast Saccharomyces cerevisiae, catalyzes the conversion of citrate to isocitrate. aco1 Delta results in mitochondrial DNA (mtDNA) instability. It has been proposed that Aco1 binds to mtDNA and mediates its maintenance. Here we propose an alternative mechanism to account for mtDNA loss in aco1 Delta mutant cells. We found that aco1 Delta activated the RTG pathway, resulting in increased expression of genes encoding citrate synthase. By deleting RTG1, RTG3, or genes encoding citrate synthase, mtDNA instability was prevented in aco1 Delta mutant …
Acidic Pericellular Ph: Effects On Proteolysis And Gene Expression As Determined In 3d Models Of Breast Carcinoma, Jennifer M. Rothberg
Acidic Pericellular Ph: Effects On Proteolysis And Gene Expression As Determined In 3d Models Of Breast Carcinoma, Jennifer M. Rothberg

Among the non-cellular microenvironmental factors that contribute to malignancy of solid tumors is an acidic peritumoral pH. The first objective was to determine if an acidic extracellular pH observed in vivo (i.e., pHe 6.8) affects the activity of proteases, such as cathepsin B, that contribute to degradation of collagen IV by tumor cells when grown in biologically relevant three-dimensional cultures. At pHe 6.8 there were increases in pericellular active cysteine cathepsins and in degradation of DQ-collagen IV, which was partially blocked by a cathepsin B inhibitor. Imaging probes for active cysteine cathepsins localized to tumors in vivo. The amount of …
