Targeting Strategies To Optimize The Therapeutic Potential Of Gold Compounds Against Her2-Positive Breast Cancers, Afruja Ahad Feb 2024

Targeting Strategies To Optimize The Therapeutic Potential Of Gold Compounds Against Her2-Positive Breast Cancers, Afruja Ahad

Dissertations, Theses, and Capstone Projects

The overexpression of HER2 accounts for 20-30% of breast cancer tumors and not only serves as a marker for poor predictive clinical outcomes but also as a target for treatment. Antibody-drug conjugates (ADCs) combine the selectivity of monoclonal antibodies (mAbs) with the efficacy of chemotherapeutic drugs to provide targeted treatment without toxicity to normal tissue. Most of the ADCs currently in the clinic for cancer chemotherapy are based on complex organic molecules. In contrast, the conjugation of metallodrugs to mAbs has been overlooked when there is enormous potential in this area with the resurgence of metal-based drugs as prospective cancer …


Multi-Target Ligand-Guided Selection (Ligs) Against B-Cell Specific Antigens Expressed In A Single Lymphoma Cell Population, Nicole B. Williams Jun 2023

Multi-Target Ligand-Guided Selection (Ligs) Against B-Cell Specific Antigens Expressed In A Single Lymphoma Cell Population, Nicole B. Williams

Nucleic acid ligands called aptamers are single-stranded DNA or RNA molecules which fold into functional three-dimensional structures to facilitate their target binding with high affinity and specificity. The method used to generate aptamers is an in vitro process called Systematic Evolution of Ligands by Exponential enrichment (SELEX). A variant of SELEX, cell-SELEX has been used to select aptamers against cell-surface proteins in their native state. We recently introduced a novel method called Ligand-Guided Selection (LIGS) to identify aptamers against cell-surface markers. Herein, we expanded LIGS method into a multiplexing platform to partition multiple aptamers against B-cell-specific antigens, CD19 and CD20, …


Synthesis, Characterization And Applications Of Peptide-Coated Nanoparticles, Mina Sadat Poursharifi Sep 2021

Ovarian Cancer (OC) is the most lethal female malignancy worldwide, mainly due to its high recurrence rate and poor diagnosis. Most patients present with late stage of the disease, and less than 25% of patients survive the five years mark. Nanotherapy provides significant and unique benefits for drug efficacy, as nanoparticles (NPs) can increase the solubility, bioavailability, and permeability of many potent drugs. Poly(lactic-co-glycolic acid) (PLGA) is one of the most successful biodegradable polymers used in NPs formulations, mainly due to its biocompatibility and biodegradability. Polyethylene glycol (PEG) is one of the most commonly used moieties to prolong the NPs …


Cell Cycle Progression Effects Of Albumin, Sharmeen Uddin Feb 2021

Cell Cycle Progression Effects Of Albumin, Sharmeen Uddin

Dissertations, Theses, and Capstone Projects

Progression through G1 phase of the cell cycle is controlled largely by growth factors in early G1 and by nutrients in late G1 indicating sufficient raw material for cell division. We previously mapped a late G1 cell cycle checkpoint for lipids upstream from a mammalian target of rapamycin complex 1 (mTORC1)-mediated checkpoint and downstream from a mid-G1 checkpoint known as the Restriction point. We therefore investigated a role for lipids in progression through late G1 into S-phase. Quiescent BJ-hTERT human fibroblasts primed back into G1 with FBS treatment, were treated with a mixture of …


An In Vitro And In Vivo Evaluation Of The Anticancer Potential Of Resveratrol And Pterostilbene Against Hpv-E6 Positive Cancers, Kaushiki Chatterjee Feb 2019

An In Vitro And In Vivo Evaluation Of The Anticancer Potential Of Resveratrol And Pterostilbene Against Hpv-E6 Positive Cancers, Kaushiki Chatterjee

Dissertations, Theses, and Capstone Projects

Cervical cancer remains as one of the most prevalent cancers effecting women globally. Lack of awareness and affordable prophylactic and therapeutic options in developing countries drive the need for alternative low-cost approaches. Dietary polyphenols have gained increased attention as possible anti-cancer agents. Our study aims to investigate whether two natural structural analogs, resveratrol and pterostilbene, exhibit anti-HPV (Human papillomavirus) activity in cervical cancer. To determine the efficacy of these polyphenols, extensive in vitro and in vivo analyses were carried out. For the in vitro studies we utilized human HeLa cells (HPV18 positive) and murine TC1 cells (HPV 16 oncogene positive). …


Strategies Involving The Food-Derived Agent Curcumin To Eliminate Brain Cancer, Sumit Mukherjee Sep 2018

Strategies Involving The Food-Derived Agent Curcumin To Eliminate Brain Cancer, Sumit Mukherjee

Dissertations, Theses, and Capstone Projects

Glioblastoma (GBM) is one of the most deadly forms of cancer with a mean 5-year survival rate of ≤5%. We have used the non-invasive strategy of long-term intranasal (IN) delivery of a glioblastoma-directed adduct of curcumin (CC), CC-CD68Ab, into the brain of murine GBM cell line GL261-implanted mice to study the therapeutic effect of CC on GBM remission. The treatment caused GBM tumor remission in 50% of GL261-implanted GBM mice. A similar rescue rate (60%) was also achieved through long-term intraperitoneal (i.p) infusion of a highly bioavailable phosphotidylcholine (PC)-encapsulated formulation of CC, Curcumin Phytosome Meriva (CCP), into the GL261-implanted GBM …


Anti-Proliferative Effects Of Garcinia Fruits In Breast Cancer Cells, Harini Anandhi Senthilkumar Feb 2018

Anti-Proliferative Effects Of Garcinia Fruits In Breast Cancer Cells, Harini Anandhi Senthilkumar

Dissertations, Theses, and Capstone Projects

Breast cancer continues to be the second leading cause of death in women, even with the recent advances in research that has led to an improved understanding of molecular pathways and targets. Increasing mortality due to recurrence and lack of targeted drugs, especially in aggressive breast cancer subtypes such as triple negative breast cancer, has gained attention from the research community. With nearly 50% of the commonly used cancer drugs being sourced from plants, bioactive small molecules derived from a natural origin have immense potential as therapeutics. This study focuses on the anti-proliferative activities of benzophenones isolated from the edible …
