A Multispecies Perspective Into Dietary Genetic Adaptations And Ancient Migration In The Peruvian Andes, Kelsey Jorgensen
A Multispecies Perspective Into Dietary Genetic Adaptations And Ancient Migration In The Peruvian Andes, Kelsey Jorgensen
Wayne State University Dissertations
Successful adaptation to the high-elevation Andes would have required both cultural and biological adaptations by early human populations. These past adaptations continue to shape the evolutionary outcomes of both humans and non-human species today. A multispecies perspective was used to examine how humans and non-human creatures, specifically insects, were shaped by past human adaptations. This dissertation asked two primary questions: 1) Given the importance and evolutionary history of potato consumption in the Peruvian Andes, is a genetic adaptation to better digest potato starch detectable in present-day Peruvians? and 2) Using the Andean Potato Weevil (APW) phylogeny as a proxy, what …
Addressing The Issue Of Missing Heritability: The Importance Of Apoptosis In Hereditary Breast And Ovarian Cancer And Functional Assessment Of Tp53i3-S252*, Sophia Chaudhry
Wayne State University Dissertations
A quarter of all cases of ovarian cancer (OVCA) cases are due to inherited factors. However, much of the genetic risk remains unknown. We have previously established the importance of whole exome sequencing to answer the question for missing heritability. We identified clinically actionable and novel risk loci in the DNA repair and cell cycle regulation pathways by assessing a cohort of women diagnosed with OVCA, wildtype for BRCA1/BRCA2 and suspected to be hereditary due to family history of breast cancer/OVCA. Equally as important was the exploration and discovery of novel risk loci in the apoptosis pathway. A total of …

Linking Molecular, Electrical And Anatomical Properties Of Human Epileptic Brain, Shruti Bagla
Wayne State University Dissertations
Epilepsy is a common neurological disorder of recurrent unprovoked seizures. It affects almost 1% of the world population. Although there is a wide range of anti-epileptic drugs (AEDs) available, they only treat the seizure symptoms and do not cure the disease itself. The poor role of AEDs can be attributed to the lack of knowledge of exact mechanisms and networks that produce epileptic activities in the neocortex. At present, the best cure for epilepsy is surgical removal of electrically localized epileptic brain tissue. Surgically removed brain tissue presents an excellent opportunity to discover the molecular and cellular basis of human …
