Growth factors of the TGF-beta family signal through type I/II receptor complexes that phosphorylate SMAD transcription factors. In this study, we analyzed signaling of all seven TGF-beta members to identify those that mediate growth through the Drosophila type I receptor BABO. We find that two potential ligands of BABO, Myoglianin (MYO) and Maverick (MAV),(More)
AIM To evaluate the indications and the safety of fiberoptic bronchoscopy (FOB) with bronchoalveolar lavage (BAL), protected specimen brushing (PSB), endobronchial biopsy (EBB), and transbronchial biopsy (TBB) in a population of very elderly patients. METHODS We performed a retrospective study of all adult patients, aged 50 years or older, who underwent(More)
Follistatin (FS) is one of several secreted proteins that modulate the activity of TGF-beta family members during development. The structural and functional analysis of Drosophila Follistatin (dFS) reveals important differences between dFS and its vertebrate orthologues: it is larger, more positively charged, and proteolytically processed. dFS primarily(More)
