Caucasian donors of biospecimens role in discovery of biomarkers for rheumatoid arthritis – BIOMEDICA CRO
Cells from a cheek swab of Caucasian and African-American donors revealed biomarkers for rheumatoid arthritis (RA) that could lead to a way to diagnose and begin treatment before the disease develops, according to a study published in Scientific Reports.
Such an early-stage RA biomarker or diagnostic has not been developed and is the focus of the current study. “Having biomarkers could allow treatment to begin even earlier before the first signs of it start,” said Michael Skinner, a professor in WSU’s School of Biological Sciences.
For the study, researchers collected buccal, or cheek, cells using a swab from two cohorts of women: a group of 26 Caucasian women from Spokane and a group of 23 African-American women from Los Angeles. In each group, about half of the women had rheumatoid arthritis with the other half serving as a control.
“If we can identify these patients ten years earlier before the disease develops, it opens up a whole arena of preventative medicine that we did not have access to before,” said Skinner.
