Contrast agents, injected into the patient during an MRI procedure and designed to be quickly cleared from the body by the
kidneys afterwards, are needed to
make fine details of organ
structures, blood vessels, and other specific tissues clearly visible in the images.
In the Nature Communications study, UTSW researchers also reported how miR - 17 causes cyst proliferation: the molecule essentially reprograms the metabolism of
kidney cells so that cellular
structures called mitochondria use less nutrients, freeing up resources to instead
make cell parts that become cysts.
