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 …
A Protective Role Of Autophagy In A Drosophila Model Of Friedreich's Ataxia (Frda), Luan Wang
A Protective Role Of Autophagy In A Drosophila Model Of Friedreich's Ataxia (Frda), Luan Wang
Wayne State University Dissertations
Friedreich’s ataxia (FRDA) is an inherited autosomal recessive neurodegenerative disease. It affects 1 in every 50,000 people in central Europe and North America. FRDA is caused by deficiency of Frataxin, an essential mitochondrial iron chaperone protein, and the associated oxidative stress damages. Autophagy, a housekeeping process responsible for the bulk degradation and turnover of long half-life proteins and organelles, is featured by the formation of double-membrane vacuoles and lysosomal degradation. Previous researches indicate that Danon’s disease, the inherited neural disorder disease that shares similar symptoms with FRDA, is due to the malfunction of autophagy. Based on this, we raise the …

Axogial Communication Mediated By Soluble Neuregulin-1 And Bdnf, Zhenzhong Ma
Wayne State University Dissertations
During peripheral nervous system development, successful communication between axons and glial cells including Schwann cells in peripheral nervous system and oligodendrocytes in central nervous system, is required for the proper functions of both neurons and glia. Three types of alternatively-spliced proteins belonging to the neuregulin1 (NRG1) gene family of growth and differentiation factors are essential for Schwann cell survival and peripheral nerve development. While membrane-bound NRG1 forms (type III) has been strongly implicated in the regulation of myelination process at late stage of Schwann cell development, little is known about the role of soluble, heparin-binding forms of NRG1 (type I/II) …
