Dissertations and Theses

This dissertation delves into the innovative application of mesoporous silica nanoparticles (MSNs) for targeted drug delivery in colorectal cancer (CRC), one of the most prevalent and deadly forms of cancer worldwide. The initial focus of the research is on developing enzyme-responsive MSNs loaded with veratridine (VTD), an alkaloid derived from natural sources that demonstrates potent anticancer activity. The nanoparticles have been engineered to deliver VTD selectively to CRC cells, releasing the payload upon being exposed to specific enzymes primarily secreted by these cells. This strategy has dual advantages of amplifying the anticancer effects while minimizing potential side effects on healthy …


Genetic Editing Out The Tumor Growth Supressor Gene Trm9l In Colorectal Cancer Models Using Crispr-Cas9, Philip Blatner May 2017

Genetic Editing Out The Tumor Growth Supressor Gene Trm9l In Colorectal Cancer Models Using Crispr-Cas9, Philip Blatner

Nanoscale Science & Engineering (discontinued with class year 2014)

Clustered regularly interspaced short palindromic repeats (CRISPR) is a precise genetic engineering tool for genome editing. CRISPR utilizes guide RNA (gRNA) to find specific DNA sequences followed by a Cas9 nuclease to cut the DNA at a specific site. TRM9L is a tumor growth-suppresser gene that restricts the growth of some colorectal cancer cells by upregulating LIN9 expression. TRM9L expression is lost in some late stage colorectal cancers and cancer models (SW620). SW480 colorectal cancer cells express TRM9L and these cells are considered to be at the beginning of colorectal cancer development. The goal of my project was to use …
