Construction And Performance Optimization Of Bioconjugated Nanosensors For Early Detection Of Breast Cancer And Pro-Inflammatory Diseases, Pooja Gaikwad
Dissertations, Theses, and Capstone Projects
In recent years, nanosensors have emerged as a tool with strong potential in medical diagnostics. Single-walled carbon nanotube (SWCNT) based optical nanosensors have notably garnered interest due to the unique characteristics of their near-infrared fluorescence emission, including tissue transparency, photostability, and various chiralities with discrete absorption and fluorescence emission bands. Additionally, the optoelectronic properties of SWCNT are sensitive to the surrounding environment, which makes them suitable for in vitro and in vivo biosensing. Single-stranded (ss) DNA-wrapped SWCNTs have been reported as optical nanosensors for cancers and metabolic diseases. Breast cancer and cardiovascular diseases are the most common causes of death …
Synthesis, Characterization And Biological Evaluation Of Polyarginine Derived Bone-Targeting Peptides, Gina L. Antuono
Synthesis, Characterization And Biological Evaluation Of Polyarginine Derived Bone-Targeting Peptides, Gina L. Antuono
Seton Hall University Dissertations and Theses (ETDs)
Osteoblast-targeting peptides in the treatment of bone disease is a new and novel approach to offering effective treatment of various cancers and can be used in bio-medical, medicinal chemistry and biotechnology applications. By targeting adhesion proteins produced by osteoblast cells, certain cancers which migrate and metastasize to the bone may be more effectively treated. An osteoblast-targeting peptide composed of Ser-Asp-Ser-Ser-Asp (SDSSD) which selectively binds to osteoblast cells via periostin has recently been identified. This peptide was functionalized with polyurethane, generating nanomicelles which encapsulated RNA for the therapeutic treatment of osteoporosis. This study has served as the basis for the research …
Investigation Of Mechanical Regulation On Stat3 Activity And Mmp Production, Jaxson R. Libby
Investigation Of Mechanical Regulation On Stat3 Activity And Mmp Production, Jaxson R. Libby
Honors Theses and Capstones
Transcription factor, STAT3, is inappropriately expressed in cancer cells, and has contrasting activation in 2D versus 3D microenvironments. 2D plates are often used for drug screening and do not always recapitulate in vivo responses. To combat inaccurate 2D drug studies, a 3D hydrogel was created to support the growth of cancer cells into a tumor-like environment. The hydrogel consists of a biocompatible dextran homopolysaccharide, cell adhesion RGD sequences, and crosslinker MMP labile peptides. A pH dependent reaction couples the RGD sequences to dextran then the polymers are crosslinked into a gel. Crosslinking is accomplished using terminal cysteine peptide sequences, allowing …
Identification Of Novel Biosynthetic Gene Clusters Encoding For Polyketide/Nrps-Producing Chemotherapeutic Compounds From Marine-Derived Streptomyces Hygroscopicus From A Marine Sanctuary, Hannah Ruth Flaherty
Identification Of Novel Biosynthetic Gene Clusters Encoding For Polyketide/Nrps-Producing Chemotherapeutic Compounds From Marine-Derived Streptomyces Hygroscopicus From A Marine Sanctuary, Hannah Ruth Flaherty
Honors Theses and Capstones
Nearly one out of six deaths in 2020, around ten million people, were caused by cancer, making it a leading cause of death worldwide (WHO, 2022). This major public health issue, in addition to the rise of multidrug-resistant (MDR) pathogens, provides a high demand for the discovery of new pharmaceutical drugs to be used clinically to treat these conditions. The Streptomyces genus accounts to produce 39% of all microbial metabolites currently approved for human health, indicating its potential as an important species to study for antimicrobial and anticancer agents. The long linear genome of Streptomyces contains specialized sequences known as …
Protacs – A Novel And Rapidly Developing Field Of Targeted Protein Degradation, Hannah R. Gatley
Protacs – A Novel And Rapidly Developing Field Of Targeted Protein Degradation, Hannah R. Gatley
Theses and Dissertations
There is a continued need for new technology and strategies for tackling cancer and other diseases, and within the current century a novel therapeutic strategy has emerged in the realm of targeted protein degradation called Proteolysis-Targeting Chimeras (PROTACs). This technology specifically targets and degrades disease-causing proteins via the ubiquitin-proteasome system, and has seen an explosion of research and intrigue in both academia and industry over the past two decades. The diversity of PROTAC classes based on the E3 ligase recruiting ligand and the target protein allows for a universal molecular structure that can be customized for a specific target and …
Engineering And Characterizing Proteins: A Dual Study On Canine P53 Protein And Cyan Thermal Protein, Dhruv B. Sitapara
Engineering And Characterizing Proteins: A Dual Study On Canine P53 Protein And Cyan Thermal Protein, Dhruv B. Sitapara
MSU Graduate Theses
This research aims to explore protein development and characterization, focusing on a dual study of canine p53 protein and cyan thermal protein. For the canine p53 protein, the goal is to comprehend its structure to better understand a key component of canine cancers. This multi-step process involved expressing the canine p53 DNA-binding domain in E. coli and purifying it through affinity and ion-exchange chromatography. The purified protein was studied to test the binding of canine p53 protein to human DNA sequences using Surface Plasmon Resonance (SPR) experiments and an Electrophoretic Mobility Shift Assay (EMSA), visualized with a SYBR-safe stain. The …
Development Of Multivalent Dna-Peptide Nucleosome Mimetics And Multi-Domain Protein Inhibitors That Directly Or Indirectly Target The E3 Ligase Uhrf1, Li Gu
University of the Pacific Theses and Dissertations
UHRF1 is an E3 ubiquitin ligase and a key epigenetic regulator establishing a crosstalk between DNA methylation and histone modification. Despite the important biochemical role of UHRF1 in cells, its overexpression has been found in almost all primary cancer types including breast cancer, lung cancer and so on. Numerous evidence indicates a strong link between tumorigenesis and UHRF1 overexpression, supporting its potential as a universal biomarker for cancer. However, UHRF1 is “yet-to-be drugged” and no highly potent chemical probes have been developed to target UHRF1 to date. In this study, we proposed two drug design approaches for UHRF1. The first …
Development And Biological Evaluation Of Selective Small-Molecule Inhibitors Of The Human Cytochrome P450 1b1, Austin Hachey
Development And Biological Evaluation Of Selective Small-Molecule Inhibitors Of The Human Cytochrome P450 1b1, Austin Hachey
Theses and Dissertations--Chemistry
The human cytochrome P450 1B1 (CYP1B1) is an emerging target for small- molecule therapeutics. Several solid tumors overexpress CYP1B1 to the degree that it has been referred to as a universal tumor antigen. Conversely, its expression is low in healthy tissues. CYP1B1 may drive tumorigenesis through promoting the formation of reactive toxins from environmental pollutants or from endogenous hormone substrates. Additionally, the expression of CYP1B1 in tumors is associated with resistance to several common chemotherapies and with poor prognoses in cancer patients. However, inhibiting CYP1B1 with small molecules has been demonstrated in cellular and murine model systems to reverse this …
