Decitabine-Loaded Nanogel Treatment To Reverse Cancer Drug Resistance, Samantha A. Cramer
Decitabine-Loaded Nanogel Treatment To Reverse Cancer Drug Resistance, Samantha A. Cramer
ETD Archive
Cancers in which epigenetic changes, such as hypermethylation of DNA, lead to drug resistance cause the cancer to become unresponsive to existing chemotherapeutic treatments. The epigenetic drug – 5-aza-2’-deoxycytidine (decitabine, DAC) – is a potent hypomethylating agent, but its effect is transient due to its instability. Previous studies have shown that loading DAC into nanogel significantly enhances its antiproliferative effect (compared to DAC in solution) in drug-resistant breast cancer cells (MCF-7/ADR). Further, the previous studies demonstrated changes in the membrane lipid profile of resistant cells following treatment with DAC either as solution or in nanogels. The objective of the present …
