This dissertation explores the nature of a divergent member of the Transforming Growth Factor-β [beta] superfamily, the non-steroidal anti-inflammatory drugs activated gene (NAG-1), as it relates to its regulation and biological activity in cancer context. Our lab has extensively studied on the molecular mechanism by which phytochemicals and NSAIDs induce apoptosis correlation with NAG-1 expression in human colorectal cancer (CRC) cells. Significant data from in vitro studies suggest that NAG-1 has an anti-tumorigenic activity which elicits apoptosis in a cyclooxygenase (COX)-independent manner in CRC cells. Indeed, NAG-1 transgenic mice developed less aberrant polyp foci (APC) compared to those of control …

Masters Theses
The use of aminoglycoside antibiotics began in 1940 with the discovery of streptomycin. The overuse and misuse of antibiotics has resulted in prevalent cases of antibiotic resistance. The most common source of aminoglycoside resistance is the presence of enzymes that covalently modify the antibiotics at specific locations. One such enzyme, APH(3′)-IIIa [the aminoglycoside phosphotransferase three prime three a] conveys resistance by transferring the γ-phosphate [gamma phosphate] from ATP [adenosine triphosphate] onto the 3′ [three prime] carbon of the aminoglycoside antibiotic sugar ring. APH(3′)-IIIa has been shown to be flexible in solution and this flexibility is proposed to be responsible for …
