ER-positive breast cancer presents differing metabolic signatures in African American, white women

New research found the most common form of breast cancer presents differing metabolic signatures in the blood of African American women with estrogen receptor-positive breast cancer compared with non-Hispanic white women. The scientists also identified a protein — negative elongation factor complex E — that was linked with higher mortality rates among African American women with estrogen receptor-positive breast cancer.

The findings, published online by Nature Scientific Reports, may help explain some of the molecular processes driving higher rates of the disease — especially more aggressive forms of it — in African American women. ER-positive breast cancer accounts for about 70%-80% of all breast cancer cases, and African American women are 40% more likely to die from it than white women, said Zeynep Madak-Erdogan, a professor of nutritional sciences and of food science and…
