Autophagy is a process that generates the necessary building components for cells by cytoplasmic breakdown of unnecessary materials (Martin, Celano, Solitro, Gunaydin, Scott, et. al., 2018). This is a survival technique for cells in times of stress, especially during periods of nutrient starvation. Cancer cells, unfortunately, benefit from this process due to their ability to flourish in nutrient-starved environments, becoming resistant to therapy. The primary protein in mammals responsible for this process is a serine/threonine kinase called ULK 1 (unc-51 like autophagy initiating kinase 1). As such, inhibitors of ULK 1 can be used in cancer therapies in order to …

Cr(VI) (hexavalent chromium) has recently been found in the drinking water of over 250 million Americans. It is a powerful oxidizing agent, and is known to cause cancer, although the specific mechanism has yet to be elucidated. There is no known preventative treatment for Cr(VI) exposure, and the US EPA is currently determining what concentration of Cr(VI) in drinking water can be safely tolerated. This study sought to test the hypothesis that Cr(VI) cytotoxicity can be prevented by various antioxidants. We tested this hypothesis by exposing human embryonic kidney and human intestinal epithelial cells to Cr(VI), with and without the …
Alpha Mangostin As A Chemoprotective Agent Via Activation Of The P53 Pathway For Breast Cancer, Vanessa Van Oost
Alpha Mangostin As A Chemoprotective Agent Via Activation Of The P53 Pathway For Breast Cancer, Vanessa Van Oost

Breast carcinoma is the most frequently diagnosed cancer among women and causes over 400,000 deaths yearly worldwide. Current treatments such as chemotherapy are not selective for cancerous tissues but are destructive to normal tissues as well. This causes a range of side effects including pain, nausea, hair loss, weakness, and more. Inactivation of p53 is an almost universal mutation within human cancer cells. The ability to activate the p53 pathway which protects cells from tumor formation is lost in 50% of cancers. Due to the prevalence of this mutation, p53 is a uniquely valuable target for applied research. Alpha mangostin …
