How estrogen receptor-positive (ER+) breast cancer responds to hormone therapy may hold keys to understanding how it will respond to radiation therapy, and an experimental drug that increases the effectiveness of hormone therapy also overcomes radiation resistance in breast cancer, a study by UT Southwestern Medical Center researchers shows.

Combining a common chemotherapy drug with an experimental nanotechnology allowed the drug to cross the blood-brain barrier and increased the survival rate in a mouse model of glioblastoma up to 50%, a team led by researchers from UT Southwestern Medical Center and UT Dallas found.

Cell membrane protrusions called blebs that typically signify the end of life for healthy cells do the opposite for melanoma cells, activating processes in these cells that help them to survive and spread, a UT Southwestern study suggests.

Researchers at UT Southwestern Medical Center have discovered how healthy bacteria can escape the intestine, travel to lymph nodes and cancerous tumors elsewhere in the body, and boost the effectiveness of certain immunotherapy drugs.

A study by UT Southwestern researchers has identified three factors that increase the risk that bunion surgery will fail to fix this painful foot condition.

Genetically modifying cells from different species allows them to adhere to each other and grow together, UT Southwestern Medical Center researchers reported in a new study.

Pelvic floor disorders (PFDs), which occur when women’s pelvic floor muscles are weakened or injured, significantly affect quality of life and require surgery for hundreds of thousands in the U.S. each year. Now a study led by UT Southwestern Medical Center researchers has found a noninvasive test that could identify women at risk for these conditions and improve treatment.

A clinical trial led by UT Southwestern Medical Center researchers demonstrates that providing healthy food directly to patients recovering from heart failure is feasible and well accepted – and could improve quality of life – helping build a foundation for larger studies exploring food as a component of medical care.

Everyone experiences stress from time to time. And while brief bouts can be a good thing, prolonged or chronic stress can have negative effects on your overall health.

With the increase in outdoor activities during the summer, a UT Southwestern Medical Center cancer specialist reminds you to protect your skin from sun damage.
