Inhibition of airway epithelial sodium channel (ENaC) function enhances mucociliary clearance (MCC). ENaC is positively regulated by channel-activating proteases (CAPs), and CAP inhibitors are therefore predicted to be beneficial in diseases associated with impaired MCC. The aims the present study were 1) identify low-molecular-weight CAPs 2) establish whether such would translate into a negative regulation vivo, consequent enhancement To this end, camostat, trypsin-like protease inhibitor,...

Abstract HOXB13 is a lineage-dependent transcription factor involved in the growth of androgen-independent prostate cancer cells. It promotes cell proliferation low-androgen environments by activating E2F signaling and inhibiting expression p21 tumor suppressor. Its restricted to largely absent from normal tissue making it an intriguing oncology target. Furthermore, reported that regulator androgen receptor (AR), ChIP-seq signature overlaps with those full-length AR splice variant lacking...

The epithelial-mesenchymal transition (EMT) is a complex change in cell differentiation that allows breast carcinoma cells to acquire invasive properties. EMT involves cascade of regulatory changes destabilize the epithelial phenotype and allow mesenchymal features manifest. As transcription factors (TFs) are upstream effectors genome-wide expression result phenotypic change, understanding sequential TF activity during provides rich information on mechanism this process. Because molecular...
