Researchers extend human epigenomic map

Ten years ago, scientists announced the end of the Human Genome Project, the international attempt to learn which combination of four nucleotides—adenine, thymine, cytosine, and guanine—is unique to homo sapien DNA. This ...

Researchers erase human brain tumor cells in mice

Working with mice, Johns Hopkins researchers have discovered that weeks of treatment with a repurposed FDA-approved drug halted the growth of—and ultimately left no detectable trace of—brain tumor cells taken from adult ...

Epigenetic changes to fat cells following exercise

Exercise, even in small doses, changes the expression of our innate DNA. New research from Lund University in Sweden has described for the first time what happens on an epigenetic level in fat cells when we undertake physical ...
