Shapeshifting tumors unmasked: New insights into master regulators reveal therapeutic vulnerabilities
Some tumors are almost impossible to treat. That's especially true for carcinomas, which don't behave like other malignancies. Some of these tumors act as shapeshifters and start to resemble cells from other organs of the ...

Epigenetic changes regulate gene expression, but what regulates epigenetics?
All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in each cell. Mistakes or ...

Redheads face impaired wound healing: MC1R dysregulation to blame, but a new treatment might help
Chronic wounds (CWs), like diabetic ulcers or pressure sores, are a major health care challenge, especially in the elderly. These wounds, marked by persistent inflammation, often lead to infection and poor patient outcomes. ...
RNA editing study finds many ways for neurons to diversify
All starting from the same DNA, neurons ultimately take on individual characteristics in the brain and body. Differences in which genes they transcribe into RNA help determine which type of neuron they become, and from there, ...
