Post-Injury Calcium Chelation Rescues Skeletal Muscle Regeneration In Mice, Matthew D. Magda Aug 2013

Post-Injury Calcium Chelation Rescues Skeletal Muscle Regeneration In Mice, Matthew D. Magda

Honors Scholar Theses

During aging the ability of skeletal muscle to regenerate after injury wanes until muscle integrity cannot be maintained. In this study it is shown that calcium chelation can restore young-like regenerative ability in an aged mouse model of skeletal muscle regeneration.


Dikar-Induced Synthetic Lethality In A Drosophila Model Of Cag Repeat Diseases Does Not Result From An Expression Feedback Loop, Daniel Camacho May 2013

Dikar-Induced Synthetic Lethality In A Drosophila Model Of Cag Repeat Diseases Does Not Result From An Expression Feedback Loop, Daniel Camacho

Honors Scholar Theses

Human CAG repeat diseases manifest themselves through the common pathology of neurodeneration. This pathological link is attributed to the property shared by all nine of these diseases: an expanded polyglutamine (polyQ) tract. The most evident result of polyQ expansion is protein aggregation, and it is believed that this phenomenon is partly responsible for conferring cytotoxic properties on the mutated protein. Apart from sequestering the mutated protein, cellular aggregates are able to incorporate native proteins via polyQ-mediated aggregation, thus disrupting important cellular pathways. Using Drosophila melanogaster as a disease model, researchers have been able to compile collections of these so-called disease ...


Investigations In Enhancing The Reproducibility Of Implantable Amperometric Glucose Biosensors For Mass Production, Dipesh Manharbhai Patel May 2013

Investigations In Enhancing The Reproducibility Of Implantable Amperometric Glucose Biosensors For Mass Production, Dipesh Manharbhai Patel

Honors Scholar Theses

Implantable glucose sensors for Diabetes management should possess several attributes such as linearity, sensitivity, selectivity, long life time and should elicit no negative tissue response. Based on this, the UConn implantable glucose sensor team has developed a 5-layer sensor architecture that simultaneously affords the aforementioned requirements. However, the large scale production of these 5-layer sensors is inhibited by the lack of high sensor-to-sensor reproducibility. Herein, we investigate the origin of sensor-to-sensor irreproducibility and develop methodologies for large-scale fabrication of these devices.


Characterizing The Role Of Cortactin In Actin Pedestal Assembly By Enterohemorrhagic Escherichia Coli (Ehec), Sarah E. Grout May 2013

Characterizing The Role Of Cortactin In Actin Pedestal Assembly By Enterohemorrhagic Escherichia Coli (Ehec), Sarah E. Grout

Honors Scholar Theses

Enterohemorrhagic Escherichia coli (EHEC) is a major foodborne cause of bloody diarrhea and renal failure. During colonization of the intestine, EHEC injects the transmembrane receptor protein Tir and the cytoplasmic effector protein EspFU into host cells to reorganize the actin cytoskeleton into adhesion “pedestals.” EspFU has been shown to bind and activate the actin nucleation factor N-WASP to drive actin polymerization into pedestals. However, EspFU can still assemble pedestals in cells lacking N-WASP, suggesting that this effector protein is able to also trigger N-WASP-independent pathways of actin polymerization during infection. Cortactin is an atypical nucleation factor that localizes to pedestals ...
