Diversity Oriented Synthesis, Characterization And Anti-Cancer Activity Of Killer Peptide Nucleolipid Bioconjugates, Niki K. Rana
Diversity Oriented Synthesis, Characterization And Anti-Cancer Activity Of Killer Peptide Nucleolipid Bioconjugates, Niki K. Rana
Seton Hall University Dissertations and Theses (ETDs)
The killer peptide sequence D-(KLAKLAK)2 has been originally designed and developed as an antibacterial agent. Despite having excellent cytotoxicity towards bacteria, this sequence maintains low cell cytotoxity in malignant mammalian cell types such as cancer. The chemical basis for its selectivity has been attributed to its poly(cationic) amphiphilic nature, which facilitates cell permeability across the negatively charged bacterial membrane, but with limited permeability across the zwitterionic membrane of mammalian cells. The positively charged D-(KLAKLAK)2 sequence has been found to accumulate on the surface of the mitochondria causing dissipation of the negatively charged mitochondrial membrane potential. This charge disruption …
Microarray Dataset Of Transient And Permanent Dna Methylation Changes In Hela Cells Undergoing Inorganic Arsenic-Mediated Epithelial-To-Mesenchymal Transition, Meredith Eckstein, Matthew Rea, Yvonne N. Fondufe-Mittendorf

The novel dataset presented here represents the results of the changing pattern of DNA methylation profiles in HeLa cells exposed to chronic low dose (0.5 µM) sodium arsenite, resulting in epithelial-to-mesenchymal transition, as well as DNA methylation patterns in cells where inorganic arsenic has been removed. Inorganic arsenic is a known carcinogen, though not mutagenic. Several mechanisms have been proposed as to how inorganic arsenic drives carcinogenesis such as regulation of the cell׳s redox potential and/or epigenetics. In fact, there are gene specific studies and limited genome-wide studies that have implicated epigenetic factors such as DNA methylation in inorganic arsenic-mediated …
Addressing Childhood Lead Poisoning Through Gis: A Proactive Approach In Scott County, Iowa, Tanner Osing
Addressing Childhood Lead Poisoning Through Gis: A Proactive Approach In Scott County, Iowa, Tanner Osing
2016-2017: Scott County, Iowa and the Scott County Health Department
In June 2016, Scott County Health Department (SHCD) officially partnered with the Upper Mississippi Center (UMC) at Augustana College as part of the Sustainable Working Landscapes Initiative (SWLI). The initiative’s main goal is to address childhood lead poisoning in Scott County, Iowa. While the health department has ongoing efforts to address the problem, there are still approximately 50 children testing positive for lead poisoning every year (Tibbets, 2016). Currently, as part of the Childhood Lead Poisoning Prevention and Control Program, the health department offers case management services for children poisoned under the age of six, follow-up inspections for residences, and …
Epigenomic Reprogramming In Inorganic Arsenic-Mediated Gene Expression Patterns During Carcinogenesis, Meredith Eckstein, Rebekah Eleazer, Matthew Rea, Yvonne N. Fondufe-Mittendorf

Arsenic is a ubiquitous metalloid that is not mutagenic but is carcinogenic. The mechanism(s) by which arsenic causes cancer remain unknown. To date, several mechanisms have been proposed, including the arsenic-induced generation of reactive oxygen species (ROS). However, it is also becoming evident that inorganic arsenic (iAs) may exert its carcinogenic effects by changing the epigenome, and thereby modifying chromatin structure and dynamics. These epigenetic changes alter the accessibility of gene regulatory factors to DNA, resulting in specific changes in gene expression both at the levels of transcription initiation and gene splicing. In this review, we discuss recent literature reports …
Genome-Wide Dna Methylation Reprogramming In Response To Inorganic Arsenic Links Inhibition Of Ctcf Binding, Dnmt Expression And Cellular Transformation, Matthew Rea, Meredith Eckstein, Rebekah Eleazer, Caroline Smith, Yvonne N. Fondufe-Mittendorf

Chronic low dose inorganic arsenic (iAs) exposure leads to changes in gene expression and epithelial-to-mesenchymal transformation. During this transformation, cells adopt a fibroblast-like phenotype accompanied by profound gene expression changes. While many mechanisms have been implicated in this transformation, studies that focus on the role of epigenetic alterations in this process are just emerging. DNA methylation controls gene expression in physiologic and pathologic states. Several studies show alterations in DNA methylation patterns in iAs-mediated pathogenesis, but these studies focused on single genes. We present a comprehensive genome-wide DNA methylation analysis using methyl-sequencing to measure changes between normal and iAs-transformed cells. …
Black Hawk County’S Approach To Lead Poisoning, Ashley Comeau, Taylor Campbell, Nathan Ambrose, Travis Pulse
Black Hawk County’S Approach To Lead Poisoning, Ashley Comeau, Taylor Campbell, Nathan Ambrose, Travis Pulse
2016-2017: Scott County, Iowa and the Scott County Health Department
Scott County, IA is facing a community lead poisoning problem, much like other counties in the state. One of these are Black Hawk County, northwest of Scott. Black Hawk County approached the lead poisoning problem by partnering with organizations including the University of Northern Iowa, the Iowa Poison Control Center, and a multitude of medical groups. Funding, procedures for action, and education were also factors in assessing the lead problem. Black Hawk County’s number of lead poisonings decreased after approaching the problem, while Scott County’s problem worsened. By using similar methods, we hope that Scott County's lead problem will also …
