Shape-shifting fat cells fuel breast cancer growth

Fat cells, or adipocytes, that grow in close proximity to breast cancers can shift into other cell types that promote tumor growth, a new study by UT Southwestern researchers suggests. The findings, published in Cell Reports, could lead to new ways to fight breast cancer, a disease that is diagnosed in more than 300,000 U.S. women each year and kills nearly 45,000 annually.

Sending Out An SOS to Protect The Heart

DALLAS – Aug. 20, 2021 – A stress signal received by the heart from fat could help protect against cardiac damage induced by obesity, a new study led by UT Southwestern researchers suggests. The finding, published online in Cell Metabolism, could help explain the “obesity paradox,” a phenomenon in which obese individuals have better short- and medium-term cardiovascular disease prognoses compared with those who are lean, but with ultimately worse long-term outcomes.

Lowering Iron in Fat Cells Prevented Weight Gain in Mice

DALLAS – June 28, 2021 – Lowering iron content in fat cells prevented mice fed a high-fat diet from gaining excess weight and developing associated health problems by limiting the amount of lipids absorbed by the intestines, UT Southwestern scientists report in a new study. The findings, published online in Cell Metabolism, could eventually lead to new strategies to protect people against obesity and related diseases.
