Can A Nanoparticle That Mimics Salmonella Effectively Combat Tumor Chemotherapy Resistance, Regino Mercado-Lubo, Beth A. Mccormick

Open Access Articles

Engineering of this semisynthetic Salmonella nanoparticle mimic introduces a new platform technology that has the capacity to be applied to various chemotherapeutic drugs to overcome multi-drug resistance in tumors.


Targeted And Controlled Anticancer Drug Delivery And Release With Magnetoelectric Nanoparticles, Alexandra Rodzinski Nov 2016

Targeted And Controlled Anticancer Drug Delivery And Release With Magnetoelectric Nanoparticles, Alexandra Rodzinski

FIU Electronic Theses and Dissertations

A major challenge of cancer treatment is successful discrimination of cancer cells from healthy cells. Nanotechnology offers multiple venues for efficient cancer targeting. Magnetoelectric nanoparticles (MENs) are a novel, multifaceted, physics-based cancer treatment platform that enables high specificity cancer targeting and externally controlled loaded drug release. The unique magnetoelectric coupling of MENs allows them to convert externally applied magnetic fields into intrinsic electric signals, which allows MENs to both be drawn magnetically towards the cancer site and to electrically interface with cancer cells. Once internalized, the MEN payload release can be externally triggered with a magnetic field. MENs uniquely allow ...


Nanobubbles Provide Theranostic Relief To Cancer Hypoxia, Christopher M. Long, Pushpak N. Bhandari, Joseph Irudayaraj Aug 2016

Nanobubbles Provide Theranostic Relief To Cancer Hypoxia, Christopher M. Long, Pushpak N. Bhandari, Joseph Irudayaraj

The Summer Undergraduate Research Fellowship (SURF) Symposium

Hypoxia is a common motif among tumors, contributing to metastasis, angiogenesis, cellular epigenetic abnormality, and resistance to cancer therapy. Hypoxia also plays a pivotal role in oncological studies, where it can be used as a principal target for new anti-cancer therapeutic methods. Oxygen nanobubbles were designed in an effort to target the hypoxic tumor regions, thus interrupting the hypoxia-inducible factor-1α (HIF-1α) regulatory pathway and inhibiting tumor progression. At less than 100nm, oxygen nanobubbles act as a vehicle for site-specific oxygen delivery, while also serving as an ultrasound contrast agent for advanced imaging purposes. Through in vitro and in vivo studies ...


Targeted Combination Treatment For Glioblastoma Multiforme (Gbm) Using Polymeric Nanoparticle, Praveena Velpurisiva, Michael Tilton, Brandon Piel, Prakash Rai May 2016

Targeted Combination Treatment For Glioblastoma Multiforme (Gbm) Using Polymeric Nanoparticle, Praveena Velpurisiva, Michael Tilton, Brandon Piel, Prakash Rai

UMass Center for Clinical and Translational Science Research Retreat

Glioblastoma Multiforme (GBM) is an aggressive cancer that originates from astrocytes and spreads to spinal cord and other parts of the brain. Increase in replication of glial cells leads to advantageous mutations in the tumor. In 2015 about 15,320 deaths were reported due to GBM. Five-year survival is less than 5% making GBM a dreadful cancer. Current treatment involves complex invasive surgery, followed by chemotherapy and radiation. There is a desperate unmet need for a targeted treatment of GBM with minimum damage to the surrounding normal tissue. Combination treatments are increasingly being used to target multiple hallmarks of cancer ...


Alternative Methods For The Treatment Of Chemo-Resistant Cancers, Kaitlyn Wong Jan 2016

Alternative Methods For The Treatment Of Chemo-Resistant Cancers, Kaitlyn Wong

Doctoral Dissertations

Great strides have been made in cancer therapy in the past century, yet it remains one of the leading causes of death in the United States today. This work aimed to shed light on novel methods to treat a variety of aggressive and often chemo-resistant cancers both in vitro and in vivo.

The first aim of this work was to evaluate the therapeutic efficacy of poly(methacryloyloxyethyl phosphorylcholine) (polyMPC) prodrugs compared to standard chemotherapeutic agents. Conjugation of polyMPC to drugs such as doxorubicin (Dox) can result in its improved solubility, prolonged half-life and therapeutic efficacy. PolyMPC and polyMPC-Dox (at a ...


Synthesis And Characterization Of Nanoparticle-Coupled Proteins In Human Serum Albumin, Kyle M. Mahoney Jan 2015

Synthesis And Characterization Of Nanoparticle-Coupled Proteins In Human Serum Albumin, Kyle M. Mahoney

University Honors Program Theses

Recently, cancer has become an ever-growing issue and has led to many researchers attempt to unravel the mystery of the disease. This research has led to a promising field of treatment: nanotechnology-coupled pharmaceuticals. Nanoparticles act as a whole unit when in conjugation with other molecules and add to the carrier molecule, most often proteins, benefits the nanoparticles themselves possess. One such carrier protein that can be conjugated with nanoparticles is Human Serum Albumin (HSA). Albumin is of interest in cancer research for two reasons: it is native to the human vasculature so it does not elicit immunological reactions, and it ...
