Elucidating Mechanisms Of Metastasis With Implantable Biomaterial Niches, Ryan Adam Carpenter
Elucidating Mechanisms Of Metastasis With Implantable Biomaterial Niches, Ryan Adam Carpenter
Doctoral Dissertations
Metastasis is the leading cause of cancer related deaths, yet it remains the most poorly understood aspect of tumor biology. This can be attributed to the lack of relevant experimental models that can recapitulate the complex and lengthy progression of metastatic relapse observed in patients. Mouse models have been widely used to study cancer, however they are critically limited to study metastasis. Most models generate aggressive metastases in the lung without the use of unique cell lines or specialized injection techniques. This limits the ability to study disseminated tumor cells (DTCs) in other relevant metastasis prone tissues. Prolonged observation of …
Cis-Resveratrol Upregulates Tyrosyl-Trna Synthetase And Inhibits The Proliferation Of Select Breast Cancer Cell Lines, Marion Cone Hope Iii
Cis-Resveratrol Upregulates Tyrosyl-Trna Synthetase And Inhibits The Proliferation Of Select Breast Cancer Cell Lines, Marion Cone Hope Iii
Theses and Dissertations
Breast cancer is one of the most commonly occurring cancers in women. 70% of breast cancer patients express ERα and are treated with tamoxifen (Tam), a drug that is used to directly target ERα. However, 20-30% of cancer patients develop a resistance to Tam. This resistance leads to a worse prognosis and other treatments such as DNA damaging drugs or radiation to eliminate these cells. Resveratrol (RSV) is a polyphenolic- compound found in plants such as grapes and hellebore and is known to evoke anti-cancer effects. While natural resveratrol exists as a mixture of both cis- and trans- isomers, so …
The Use Of Natural Anthraquinone Emodin As A Primary And Complementary Therapeutic In The Treatment Of Colorectal Cancer, Alexander-Jacques Theodore Sougiannis
The Use Of Natural Anthraquinone Emodin As A Primary And Complementary Therapeutic In The Treatment Of Colorectal Cancer, Alexander-Jacques Theodore Sougiannis
Theses and Dissertations
5 Fluorouracil (5FU) chemotherapy is widely used in the treatment of colorectal cancer (CRC), and has been the first-choice chemotherapy drug for CRC for many years. However, nearly 10% of patients receiving chemotherapy die during the first 30 days of treatment. Further, it is estimated that 70% of surviving patients will develop non-specific toxicities as a result of chemotherapy treatment. We characterize these toxicities in an animal model of chemotherapy treatment and show that perturbations in the gut microbiome might be exacerbate the prolonged effects of chemotherapy. A compound that could attenuate the multiple non-selective toxicities associated with chemotherapy could …
Investigation On Nanoparticle Based Combination Therapy For Targeted Cancer Treatment, Muhammad Raisul Abedin
Investigation On Nanoparticle Based Combination Therapy For Targeted Cancer Treatment, Muhammad Raisul Abedin
Doctoral Dissertations
“The current treatment methods in cancer are associated with toxicity in healthy tissues, partial therapeutic response, drug resistance and finally recurrence of the disease. The cancer drugs are challenged by non-specific binding, undesired toxicity in healthy cells, low therapeutic index and finally poor therapeutic outcome. In this work, a targeted nanoscale therapeutic system Antibody Drug Nanoparticle (ADN) was engineered to selectively inhibit the breast cancer cell growth with reduced toxicity in healthy cells. The ADNs were designed by synthesizing rod shaped anoparticles using pure chemotherapeutic drug and covalently conjugating a therapeutic monoclonal antibody (mAb) on the surface of the drug …
Artificial Synthetic Scaffolds For Tissue Engineering Application Emphasizing The Role Of Biophysical Cues, Samerender Nagam Hanumantharao
Artificial Synthetic Scaffolds For Tissue Engineering Application Emphasizing The Role Of Biophysical Cues, Samerender Nagam Hanumantharao
Dissertations, Master's Theses and Master's Reports
The mechanotransduction of cells is the intrinsic ability of cells to convert the mechanical signals provided by the surrounding matrix and other cells into biochemical signals that affect several distinct processes such as tumorigenesis, wound healing, and organ formation. The use of biomaterials as an artificial scaffold for cell attachment, differentiation and proliferation provides a tool to modulate and understand the mechanotransduction pathways, develop better in vitro models and clinical remedies. The effect of topographical cues and stiffness was investigated in fibroblasts using polycaprolactone (PCL)- Polyaniline (PANI) based scaffolds that were fabricated using a self-assembly method and electrospinning. Through this …
Enhanced Label Free Normal And Cancer Cells Classification Using Combined Parametric Modeling And Optical Techniques, Ayshathul Fouzia Abdul Gani
Enhanced Label Free Normal And Cancer Cells Classification Using Combined Parametric Modeling And Optical Techniques, Ayshathul Fouzia Abdul Gani
Dissertations
The development of label-free methods for cell classifications has been driven by the importance of early detection and identification of cancer disease. The future point-of-care (POC) treatment methods require rapid and real-time cancer screening techniques. As the labelled methods of cell classification are time-consuming processes and require a large amount of sample preparation along with skilled persons, they do not appear to be suitable for POC treatment methods. This necessitates the importance of such development. The label-free methods incorporate the biophysical properties of cells instead of biomarkers. The optical properties of cells have been frequently utilized for cell classification. This …
