Vanadium Compounds Modulate Osteoblast Proliferation And Function, Bryan Sosa Aug 2019

Vanadium Compounds Modulate Osteoblast Proliferation And Function, Bryan Sosa

Seton Hall University Dissertations and Theses (ETDs)

Osteoblastogenesis is an essential part of the bone healing process. Insulin has been shown to improve bone healing in both normal and diabetic bone healing models. In addition, insulin mimetic compounds such as Zinc chloride (ZnCl2) and Vanadyl acetylacetonate (VAC) have also been shown to improve bone healing in these models as well. The purpose of this study was to determine the effects of vanadium compounds VAC and Vanadium (II) sulfate (VSO4) in osteoblast proliferation and function. In addition the mechanisms by which growth and function are facilitated by these Vanadium compounds were also evaluated. In …

Zinc Chloride Enhanced Chondrogenesis Is Vegf Dependent, Gilbert M. Sharp Iv Jun 2019

Zinc Chloride Enhanced Chondrogenesis Is Vegf Dependent, Gilbert M. Sharp Iv

Seton Hall University Dissertations and Theses (ETDs)

Researchers have begun investigating whether insulin mimetics such as ZnCl2 could promote bone healing in both non-diabetic and diabetic fracture healing similarly to insulin. Our research focused on understanding the mechanism by which ZnCl2 affects chondrogenesis, an important component of bone fracture healing. The increases in proteoglycan deposition and cell proliferation seen in our data may be a result of ZnCl2 induction of the IGF-1 pathway. When the VEGF pathway was inhibited in ZnCl2- or insulin-treated cells significant decreases in proteoglycan deposition occurred on day 7 and 14 (P=0.007 for ZnCl2, P=0.028 for insulin) when compared to controls. This data …

Effects Of Crude Oil On Tumor Suppressor P53 Polymorphisms In Laboratory-Exposed Atlantic Killifish, Fundulus Heteroclitus, Allison Margaret Nadler Dec 2017

Effects Of Crude Oil On Tumor Suppressor P53 Polymorphisms In Laboratory-Exposed Atlantic Killifish, Fundulus Heteroclitus, Allison Margaret Nadler

Seton Hall University Dissertations and Theses (ETDs)

Polycyclic aromatic hydrocarbons (PAHs), constituents of crude oil, are implicated as a potent source of adverse toxicological effects on living organisms. To model the effects of PAHs in response to environmental oil spill disasters a species of killifish (Fundulus heteroclitus) was captured and exposed to crude oil in a laboratory-controlled setting. Over a period of 7 days, fish were dosed with crude oil by gavage, culled, and organs were harvested for analysis. Excitation-emission matrix spectroscopy (EEMS) of gall bladder tissue homogenates was used to verify exposure. Effects of PAHs on the p53 gene were evaluated as an indicator …

B7h6: A Cancer Biomarker For The Development Of Novel Immunotherapy Approaches, Mariana Phillips May 2017

B7h6: A Cancer Biomarker For The Development Of Novel Immunotherapy Approaches, Mariana Phillips

Seton Hall University Dissertations and Theses (ETDs)

Cancer-based immunotherapy has led the evolution of biologics that can stimulate immune responses towards tumor eradication. The synthesis of small to intermediate size molecules with the targeting and effector functions of mAb may represent a novel class of immunotherapeutics that may overcome the limitations of their biological counterparts.Towards this objective, B7H6 has been identified as a protein ligand localized on the cell surface of transformed tumor cells. B7H6 binds specifically to the activating receptor NKp30, constitutively expressed on all resting and active NK cells. Upon ligand:receptor binding, B7H6 triggers NK cell activation and release of chemokines and pro-inflammatory cytokines such …

A Bioinformatics Methodology For The Annotation And Analysis Of Sperm Chromatin Remodeling Proteins In Sequenced Drosophila Species, Zain A. Alvi Dec 2016

A Bioinformatics Methodology For The Annotation And Analysis Of Sperm Chromatin Remodeling Proteins In Sequenced Drosophila Species, Zain A. Alvi

Seton Hall University Dissertations and Theses (ETDs)

Spermatogenesis is the process by which mature functional spermatozoa are formed, and is initiated in the stem cell niche of the testes. During the post-meiotic stage of spermatogenesis, spermiogenesis, transition proteins facilitate the transformation of chromatin from a histone-based nucleosome structure to a protamine-based nucleosome structure. This study is aimed at analyzing genomic, transcript, and protein sequences of transition proteins in 13 sequenced Drosophila species. The Drosophila melanogaster spermatid specific transition protein-like protein (Tpl94D) was used as the reference sequence in this study. An extensive bioinformatics approach was employed in establishing the Tpl94D orthologs. We identified …

Poly(Arginine) Derived Cancer-Targeting Peptides For The Development Of A Cancer-Targeted Gene Therapy Approach In Hepg2 Liver Cancer Cells, Stesha C. Joseph Aug 2014

Poly(Arginine) Derived Cancer-Targeting Peptides For The Development Of A Cancer-Targeted Gene Therapy Approach In Hepg2 Liver Cancer Cells, Stesha C. Joseph

Seton Hall University Dissertations and Theses (ETDs)

Cancer is a disease that has eluded medicinal approaches for many years and as a result new and improved therapeutic approaches are in constant demand. Although chemotherapy and radiation treatments have assisted in suppressing the growth of tumors, their poor selectivity and efficacy are major limitations for effective therapy en route towards the development of a cure for the cancer epidemic. With the mission of conquering cancer at heart, researchers have pursued a new form of cancer therapy, aptly named, a cancer targeting approach. This method revolves around the selection of a suitable biomarker, typically a cell surface receptor …

Partial Sequencing Of A Balbiani Ring Gene And Development Of A Molecular Probe, Kerri Ann Kurzeja Jan 1998

Partial Sequencing Of A Balbiani Ring Gene And Development Of A Molecular Probe, Kerri Ann Kurzeja

Seton Hall University Dissertations and Theses (ETDs)

The Environmental Protection Agency is currently developing sediment quality criteria in order to protect the nation's water sources. In order to assist in the development of standards for the disposal of heavy metals, our laboratory is undergoing sediment toxicity studies on Chironomus riparius. It is an EPA approved test organism that spends most of its life in the sediment. Following a previous study (Cochrane et al., 1994), the organism's response to heavy metals will be monitored on the genetic level. Several genes, including a Balbiani ring (BR) gene, which was the focus of this thesis, will be studied to determine …
