Intrapulmonary Inoculation Of Multicellular Tumor Spheroids To Construct An Orthotopic Lung Cancer Xenograft Model That Mimics Four Clinical Stages Of Non-Small Cell Lung Cancer, Yingbo Huang
University of the Pacific Theses and Dissertations
Lung cancer leads in mortality among all types of cancer in the US and Non-small cell lung cancer (NSCLC) is the major type of lung cancer. Immuno-compromised mice bearing xenografts of human lung cancer cells represent the most common animal models for studying lung cancer biology and for evaluating potential anticancer agents. However, orthotopic lung cancer models based on intrapulmonary injection of suspended cancer cells feature premature leakage of the cancer cells to both sides of the lung within five days, which generates a quick artifact of metastasis and thus belies the development and progression of lung cancer as seen …
Investigating The Effect Of Rutaecarpine On The Benzo[A]Pyrene-Induced Dna Damage In Vitro, You Li
Investigating The Effect Of Rutaecarpine On The Benzo[A]Pyrene-Induced Dna Damage In Vitro, You Li
University of the Pacific Theses and Dissertations
Benzo[a]pyrene (BaP), is one of the most potent mutagens and carcinogens known. It requires metabolic activation through cytochrome P450 (CYP)1A1 to yield the ultimate carcinogenic metabolite, benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide (BPDE). BPDE can bind to DNA and form predominantly covalent (+) trans adducts at the N2 position of guanine causing DNA damage. Rutaecarpine (RTC) is an herbal medicine that has been used to treat several diseases such as headache, hypertension, gastrointestinal disorders, amenorrhea, and anti-inflammation. It has also been reported as a potent inducer of CYP enzymes, including CYP1A1, and CYP1A2. The mechanisms underlying up-regulation of CYP1A1 by RTC is dependent on aryl …
Development Of A New Class Of Ligand-Targeted Chemotherapeutics With Enhanced Safety And Efficacy Profile, Arindom Pal
Development Of A New Class Of Ligand-Targeted Chemotherapeutics With Enhanced Safety And Efficacy Profile, Arindom Pal
University of the Pacific Theses and Dissertations
The hydrophobicity of many chemotherapeutic agents usually results in their nonselective passive distribution into healthy cells and organs causing collateral toxicity. Ligand-targeted drugs (LTDs) are a promising class of targeted anticancer agents. The hydrophilicity of the targeting ligands in LTDs limits its nonselective passive tissue distribution and toxicity to healthy cells. In addition, the small size of LTDs allows for better tumor penetration, especially in the case of solid tumors. However, the short circulation half-life of LTDs, due to their hydrophilicity and small size, remains a significant challenge for achieving their full therapeutic potential. Therefore, extending the circulation half-life of …
