Accuracy of individual variables in the monitoring of long-term change in pulmonary sarcoidosis as judged by serial high-resolution CT scan data.

Background: In pulmonary sarcoidosis, the optimal means of quantifying change is uncertain. The comparative usefulness of simple lung function trends and chest radiography remains unclear. We aimed to explore and contrast the disease-monitoring strategies of serial pulmonary function tests (PFTs) and chest radiography compared against morphologic change on high-resolution CT (HRCT) scan.

HGF/c-MET targeted therapeutics: novel strategies for cancer medicine.

The hepatocyte growth factor/mesenchymal-epithelial transition factor (HGF/c-MET) receptor tyrosine kinase (RTK) pathway plays a pleotropic role in cell proliferation, migration, invasion, angiogenesis and survival. Although it has critical physiological functions in embryonic development and tissue repair, this signaling cascade is frequently deregulated in a wide range of tumors. Aberrant HGF/c-MET signaling, driven by various mechanisms, including constitutive activation and over-expression, has multifunctional effects in oncogenesis and is implicated in the acquisition of an aggressive phenotype with metastatic potential.
