We have examined the effects of transforming growth factor beta 1 (TGF-beta 1) on the growth of paired murine melanoma cell clones that differ with respect to their experimental metastatic potential. Neither poorly (clone 16) nor highly (clone M2) metastatic cells were capable of anchorage-independent growth in 0.3% agar/Dulbecco's modified Eagle's medium in the absence of serum. However, both ...

AIM To analyse patterns of gene expression for peptide regulatory factors in patients with Dupuytren's contracture. METHODS Tissue samples (palmer fascia) from 12 patients with Dupuytren's contracture and 12 controls were studied using the reverse transcription/polymerase chain reaction (RT/PCR) technique. RESULTS Tissue from patients with Dupuytren's contracture expressed a higher percenta...

Mutations in genes encoding members of the transforming growth factor (TGF)-beta superfamily have been identified in idiopathic forms of pulmonary arterial hypertension (PAH). The current study examined whether perturbations to the TGF-beta/Smad2,3 signalling axis occurred in a monocrotaline (MCT) rodent model of experimental PAH. Expression of the TGF-beta signalling machinery was assessed in ...
