DNA Methylation and Glucocorticoid Resistance Offers Clues to Improve Cancer Drugs

May 12, 2015 Bailey Kirkpatrick

Scientists from St. Jude Children’s Research Hospital conducted a study that illuminates a mechanism by which leukemia cells resist steroids, a key factor detrimental to the success of chemotherapy. This discovery could help create more effective cancer drugs and improve the treatment of many autoimmune related diseases. The researchers looked at a certain type of steroid hormones involved in the immune system, known as glucocorticoids. These hormones are crucial components to the chemotherapy drug cocktail that has helped increase long-term [more…]

New Study Shows Epigenetic Process Controls Cancer-Killing Cells

October 1, 2013 WhatIsEpigenetics

A new study from the scientists at the University of Southern California (USC) describes for the first time how natural killer (NK) cells, which are able to kill and contain viruses and cancerous tumors in the human body, can be manipulated by epigenetics. Through a series of experiments in mice, these scientists found that MYSM1, an enzyme in the body’s immune system that turns genes on and off by modifying proteins called histones embedded in DNA, is required for natural [more…]
