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, ...

Order of genetic mutations shapes cancer's development and patient outcomes
In many aspects of our lives, we find meaning in the order in which events occur. We buy into myths about "middle child syndrome," talk of calm before storms, and consider it strange to start a meal with dessert.
