A “Universal Cancer Biomarker”
March 26, 2019 | Terry Sharrer
According to University of Queensland bioengineers: “When circulating tumor DNA fragments are placed in water, they begin to fold into 3D shapes different than DNA from healthy cells—driven by the dense clusters of methyl groups found along DNA molecules that have been reprogrammed by cancer.” Knowing that, the Australian scientists used a device with gold nanoparticles to electrochemically attract those DNA fragments from patients with breast, prostate and colorectal cancer and lymphoma. This diagnostic has shown a 90% accuracy for 200 samples of cancerous and normal DNA. MORE
