Exosomal Cannabidiol: A Promising Candidate For Targeted Oral Delivery Against Breast Cancer., Disha Nagesh Moholkar

Electronic Theses and Dissertations

Cancer therapies are limited by lack of specificity, selectivity and numerous adverse effects. Repurposing potential anticancer compounds with appropriate drug carriers can help overcome these drawbacks. In our present study, we address the major obstacle for cannabidiol (CBD): its low oral bioavailability, using exosomes. Exosomes (Exo) are promising non-toxic and biocompatible drug delivery vehicles Our project aims are to address the research gap by formulating exosomal cannabidiol (ExoCBD): a tumor-targeted oral delivery system for the treatment of breast cancer. The targeting approach relies on the overexpression of folate receptors at the tumor site by using folic acid functionalized exosomes (FA-Exo). …

Worldwide female breast cancer is the most commonly diagnosed cancer, with an estimated 2.3 million new cases in 2020, reason for the need of targeted therapies that can maximize treatment success and minimize toxicity. Nanoparticles of gold (AuNps) exhibit cytotoxic properties against certain types of cancer cell lines. Nanofibers have been use in the drug delivery systems due to its degradability and high surface area. We proposed a membrane with nanometric fibers using polivinilic alcohol (PVA) and chitosan (Qts) loaded with AuNps and Doxorubicin (Doxo) with the purpose of diminish tumor regression.

PVA-Qts membrane was develop with electrospinning, the injection, …

Tumor-Targeted Ph-Sensitive Manganese Oxide Nanoparticle For Enhanced Detection Of Breast Cancer Using Mri, Celia Martinez De La Torre

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the United States, approximately 287,850 new cases of invasive breast cancer will be diagnosed, and over 43,000 women will die because of it in 2022. Currently, mammography is the gold standard for breast cancer surveillance. Although this detection technique is relatively cheap and fast, it misses about 1 in 5 breast cancers in younger women with dense breast tissue, causing a delay in treatment. Compared to mammography, magnetic resonance imaging (MRI) has superior soft-tissue contrast that elucidates structural differences within soft tissue to detect more breast cancers. However, MRI still misses

NEMO particles were produced by synthesizing manganese oxide …

Exploiting Modulation Of The Blood-Brain And Blood-Tumor Barrier Permeability By Translational Focused Ultrasound For Therapeutic Delivery To Cns Metastases, Tasneem A. Arsiwala

Graduate Theses, Dissertations, and Problem Reports (ETD)

Transcranial low-intensity focused ultrasound is a unique technology to modulate the integrity of tight endothelial junctions and transiently increase BBB/BTB permeability to enhance therapeutic delivery. Despite promising early studies, present literature lacks agreement on key experimental conditions, which restricts our knowledge and the technique's widespread translation. This dissertation first provides a critical review of the current gaps in knowledge regarding the universal use of LiFUS in preclinical and clinical use. We then identify key parameters for translational and predictable opening of the BBB using a 3T MRI coupled with a clinical device. Our investigation highlights that passive permeability of the …

Nanoparticle-Mediated Therapeutic Agent Delivery For Treating Metastatic Breast Cancer—Challenges And Opportunities, Yunfei Li, Brock Humphries, Chengfeng Yang, Zhishan Wang

Toxicology and Cancer Biology Faculty Publications

Breast cancer (BC) is the second leading cause of cancer-related death in American women and more than 90% of BC-related death is caused by metastatic BC (MBC). This review stresses the limited success of traditional therapies as well as the use of nanomedicine for treating MBC. Understanding the biological barriers of MBC that nanoparticle in vivo trafficking must overcome could provide valuable new insights for translating nanomedicine from the bench side to the bedside. A view about nanomedicine applied in BC therapy has been summarized with their present status, which is gaining attention in the clinically-applied landscape. The progressions of …
