A compound found in green tea could have lifesaving potential for patients with multiple myeloma and amyloidosis, who face often-fatal medical complications associated with bone-marrow disorders, according to a team of engineers at Washington University in St. Louis and their German collaborators.
The compound epigallocatechine-3-gallate (EGCG), a polyphenol found in green tea leaves, may be of particular benefit to patients struggling with multiple myeloma and amyloidosis. These patients are susceptible to a frequently fatal condition called light chain amyloidosis, in which parts of the body’s own antibodies become misshapen and can accumulate in various organs, including the heart and kidneys.
Bieschke’s team first isolated individual light chains from nine patients with bone marrow disorders that caused multiple myeloma or amyloidosis, then ran lab experiments to determine how the green tea compound affected the light chain protein.
Bieschke previously examined EGCG’s effect in both Parkinson’s and Alzheimer’s disease, and found it prevented dangerous buildups of protein present in both diseases. His team had a similar conclusion in this study: In bone marrow patients, the EGCG transformed light chain amyloid, preventing the misshapen form from replicating and accumulating dangerously.
