Differential Gene Expression In Response To Hypoxia And Acidosis In Chest Wall Deformities And Chondrosarcoma, Jamie L. Durbin Apr 2018

Differential Gene Expression In Response To Hypoxia And Acidosis In Chest Wall Deformities And Chondrosarcoma, Jamie L. Durbin

Biological Sciences Theses & Dissertations

The importance of understanding how costal cartilage chondrocytes respond to stimuli such as oxidative stress and low pH has been largely overlooked in studies involving tissue culturing due to major differences between oxygen and pH levels during incubation and the natural environment of hyaline cartilage. Hyaline cartilage is avascular and naturally hypoxic which subsequently leads to increased glycolytic metabolism and ultimately causes a decrease in extracellular pH. To examine how healthy costal cartilage responds to these extreme growth conditions, we examined responses in three hyaline cartilage diseases. Our ability to identify the disease mechanisms responsible for pectus excavatum, pectus carinatum, …


Patterns Of Gene Expression From Human Costal Cartilage In Relation To The Chest Wall Deformity Pectus Carinatum, Janna E. Grubbs Apr 2013

Patterns Of Gene Expression From Human Costal Cartilage In Relation To The Chest Wall Deformity Pectus Carinatum, Janna E. Grubbs

Biological Sciences Theses & Dissertations

Cartilage deformities within the human chest wall, specifically pectus excavatum (PE) and pectus carinatum (PC) are common (1/400-1/1000) and yet, despite their clinical significance, are some of the least studied disorders pertaining to cartilage [1]. The costal cartilage connecting "false ribs" 8-10 to the sternum is often abnormally grown and can lead to formation of a severely sunken "funnel" chest (PE) or push outwards to form a "pigeon" chest (PC). Both conditions can have impact on the diaphragm, heart, lungs, and psychological function. An established ratio of PE and PC in males to females is 4:1, indicating a sex-linked male …
