Terahertz Electromagnetic Effects And Chirality-Induced Spin Selectivity In Dna, F. Matthew Mihelic Md
Terahertz Electromagnetic Effects And Chirality-Induced Spin Selectivity In Dna, F. Matthew Mihelic Md
Faculty Publications
The effects of terahertz electromagnetic stimulation of the DNA molecule can be understood through modeling of the quantum logical mechanics of the DNA molecule. Coherent conduction of electron spin states along the aromatic nucleotide base pairs and chirality-induced spin selectivity are two characteristics of the DNA molecule that are involved in the precise separation of the double-stranded DNA molecule at a specific location. Such modeling can inform predictions of DNA strand separation and has significant implications for understanding DNA transcription bubble formation.
Identifying The Molecular Cause Of Extreme Endoplasmic Reticulum Dilation In Pediatric Osteosarcoma And Its Relationship To The Disease, Rachael Wood
Theses and Dissertations (ETD)
Pediatric osteosarcoma tumors are characterized by an unusual abundance of grossly dilated endoplasmic reticulum and an immense genomic instability that has complicated identifying new effective molecular therapeutic targets. Here we report a novel molecular signature that encompasses the majority of 108 patient tumor samples, PDXs and osteosarcoma cell lines. These tumors exhibit reduced expression of four critical COPII vesicle proteins that has resulted in the accumulation of procollagen-I protein within ‘hallmark’ dilated ER. Using CRISPR activation technology, increased expression of only SAR1A and SEC24D to physiologically normal levels was sufficient to restore both collagen-I secretion and resolve dilated ER morphology …
Genetic Mechanisms Of Transcriptional Regulation In Childhood Acute Lymphoblastic Leukemia, Xujie Zhao
Genetic Mechanisms Of Transcriptional Regulation In Childhood Acute Lymphoblastic Leukemia, Xujie Zhao
Theses and Dissertations (ETD)
Introduction. Advances in genomic profiling and sequencing studies have identified germline and somatic variations that are associated with childhood ALL, improving our understanding of the genetic basis of childhood acute lymphoblastic leukemia (ALL). Recent genome-wide association studies (GWAS) have identified germline genetic variations of ARID5B and, more recently, IGF2BP1 that are associated with susceptibility to ALL. Genome-wide sequencing studies also discovered a new ALL subtype characterized of ZNF384-mediated chromosomal translocations, providing new insights into genetic heterogeneity in childhood ALL. However, the underlying mechanism by which these genetic variants contribute to the transcriptional regulatory circuitries of ALL is still poorly understood. …
Investigating The Role Of Znf384 Rearrangements In Acute Leukemia, Kirsten Dickerson
Investigating The Role Of Znf384 Rearrangements In Acute Leukemia, Kirsten Dickerson
Theses and Dissertations (ETD)
Chromosomal rearrangements involving ZNF384 are the defining lesion in 5% of pediatric and adult B-cell acute lymphoblastic leukemia and tumors are characterized by aberrant myeloid marker expression. Additionally, ZNF384 rearrangements are the defining lesion in nearly half of pediatric B/myeloid mixed phenotype acute leukemia. These fusions juxtapose full-length ZNF384 to the N terminal portion of a diverse range of partners, most often, transcription factors or epigenetic modifiers. It has been shown that ZNF384-rearranged tumors have a distinct gene expression profile that is consistent between disease groups and N terminal partners. Genomic analyses of patient tumors has shown that ZNF384 fusions …
