Tumor Multicomponent Targeting Polymer-Lipid Hybrid Nanoparticles To Overcome Drug Resistance In Renal Cell Carcinoma, Hashem Obaid Alsaab Jan 2018

Tumor Multicomponent Targeting Polymer-Lipid Hybrid Nanoparticles To Overcome Drug Resistance In Renal Cell Carcinoma, Hashem Obaid Alsaab

Wayne State University Dissertations

Renal Cell Carcinoma (RCC) contributes to more than 90% of the most common form of kidney tumor and remains one of the ten leading causes of cancer death in the United States. Although surgery remains an option for operable tumors, high metastatic index and resistance to radiation and chemotherapies prompted recent development of therapeutics that target the RCC angiogenesis and cell proliferation pathways. Tyrosine kinase inhibitors or TKIs (Cabozantinib, Axitinib, Sorafenib, and Sunitinib) and mammalian target of rapamycin (mTOR) inhibitors (Temsirolimus and Everolimus) have increased the therapeutic options for treating RCC. Although the impact towards decreasing disease progression is encouraging, …

Multiple myeloma is a hematological malignancy characterized by clonal proliferation of plasma cells generally caused by chromosomal abnormalities. It occurs in the bone marrow, which is the microenvironment of multiple myeloma. Exosomes (EXs) are 30-100 nm membrane-derived micro-vesicles containing various of bioactive molecules, such as microRNAs, to mediate the cell-cell interaction. Numerous studies reported that exosomes play a significant role in tumor microenvironment. Angiogenesis has the important implication in tumor exacerbation to supply nutrients to promote the progression of cancer cells through endothelial cells (ECs). Some studies demonstrated that microRNA-29b (miR-29b) can suppress tumor development and inhibit angiogenesis. Therefore, in …
