Newly discovered cells restore liver damage in mice without cancer risk

The liver is unique among organs in its ability to regenerate after being damaged. Exactly how it repairs itself remained a mystery until recently, when researchers supported by the National Institutes of Health discovered a type of cell in mice essential to the process. The researchers also found similar cells in humans.

Research reveals unintended consequences of inappropriate medical food use in managing patients with a type of metabolic disorder

Many “medical foods” are designed to help manage patients with rare inborn errors of metabolism (IEMs), and can help prevent serious and life-threatening complications. However, such special foods may cause harm in some patients when their use is not carefully monitored and managed, according to a research team led by scientists at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health.

Tell-tale biomarker detects early breast cancer in NIH-funded study

nibib-12_l_0.jpg
Metastasis occurs when cells are shed from primary breast cancer tumor and establish a new tumor at a distant site. For early detection of the metastasis with MRI, the Lu Lab developed a probe that binds to fibrin-fibronectin protein complexes in high-risk tumors. Fibronectin is expressed in high-risk (aggressive) cancer and not in normal tissue, so MRI imaging is able to distinguish metastases from normal tissue.
