Effects of Genistein Following Fractionated Lung Irradiation in MicePara, Andrea 22 September 2009 (has links)
Radiation therapy for lung cancer and cancers of the upper thorax is limited by side effects to normal tissue of the lung. An understanding of mechanisms leading to radiation induced lung damage is essential to developing protective agents. In this thesis an anti-oxidant and anti-inflammatory agent Genistein was investigated for its potential to affect DNA damage, tissue inflammation, functional deficits and survival. We hypothesized that chronic oxidative stress and the subsequent inflammatory response play a key role in the development of major lung complications, radiation pneumonitis and fibrosis. If side effects of radiation could be reduced, then larger doses could be delivered to the tumor with a better chance of eradicating the disease.

GROUP VIA CALCIUM-INDEPENDENT PHOSPHOLIPASE A2 REGULATES BCL-XL PROTEIN LEVELS IN MICE LUNGNam, Sang-Jin 01 January 2014 (has links)
With previous indication of the Group VIA phospholipase A2 (iPLA2β) enzyme regulating ER-stress induced apoptosis in β-cells by regulating the anti-apoptotic protein Bcl-xL via alternative splicing, our lab postulated iPLA2β to be utilizing a similar mechanism to regulate apoptosis in mice lung. Our previous lab work has shown implications of lung function compromise in iPLA2β-/- mice, and we speculated the cause to be due altered lung architecture stemming from the attenuation of apoptosis. The western blot analysis in this study suggested that iPLA2β is involved in the regulation of Bcl-xL, but the mRNA ratios of the splice variants suggested that alternative splicing is not the mechanism iPLA2β is utilizing for the regulation in our animal models. Additionally, the observation and assessment of the lung morphology of the iPLA2β-/- and wild type mice suggested that iPLA2β does not play an integral role in lung morphology.

Phenotype characterization of lung structure in inbred mouse strains using multi modal imaging techniquesNamati, Jacqueline Thiesse 01 May 2009 (has links)
Research involved in modeling human lung disease conditions has provided insight into disease development, progression, and treatment. In particular, mouse models of human pulmonary disease are increasingly utilized to characterize lung disease conditions. With advancements in small animal imaging it is now possible to investigate the phenotypic differences expressed in inbred mouse strains in vivo to investigate specific disease conditions that affect the lung.
In this thesis our aim was to generate a comprehensive characterization of the normative mouse lung phenotypes in three of the most utilized strains of mice, C57BL/6, A/J, and BALB/c, through imaging techniques. The imaging techniques that we utilized in this research included micro-CT, a custom Large Image Microscope Array (LIMA) system for 3D microscopy, and classical histology. Micro-CT provided a non-destructive technique for acquiring in vivo and fixed lung images. The LIMA 3D microscopy system was utilized for direct correspondence of the gold standard histology images as well as to validate the anatomical structures and measurements that were extracted from the micro-CT images. Finally, complete lung histology slices were utilized for assessment of the peripheral airspace structures that were not resolvable using the micro-CT imaging system.
Through our developed imaging acquisition and processing strategies we have been able to successful characterize important phenotypes in the mouse lung that have not previously been known as well as identify strain variations. These findings will provide the scientific community with valuable information to be better equipped and capable of pursuing new avenues of research in investigating pulmonary disease conditions that can be modeled in the mouse.
