These projects focus on developing targeted therapies for drug-resistant tumors, with the goal of providing unique treatment options that are developed from cutting-edge science.
Researchers found that the DUX4 gene is normally expressed only in early development but its suppression is inefficient in FSHD patients. This leads to toxic bursts of protein causing muscle cell death and muscular dystrophy.
The study found that radiation exposure increases the risk of both first and second cancers to a similar degree, with higher risks for radiation-sensitive cancers like lung, colon, breast, thyroid, and bladder cancers. Cancer survivors with a history of radiation exposure should continue to be closely monitored for second cancers.
