Is loss of parafibromin immunoreactivity a distinguishing feature of parathyroid carcinoma?
Parafibromin is a promising molecular marker for diagnosing parathyroid carcinoma. The similar loss of parafibromin immunoreactivity in HPT-JT syndrome-related adenomas suggests that this is a pivotal step in parathyroid tumorigenesis.
In addition to protecting myocardial cells, preconditioning also protects coronary endothelial cells against ischemia/reperfusion injury.
