Exaggerated BMP4 signalling alters human airway basal progenitor cell differentiation to cigarette smoking-related phenotypes [array]

ABSTRACT: Airway remodelling in chronic obstructive pulmonary disease (COPD) originates, in part, from smoking-induced changes in airway basal stem/progenitor cells (BCs). Based on the knowledge that bone morphogenetic protein 4 (BMP4) influences epithelial progenitor function in the developing and adult mouse lung, we hypothesised that BMP4 signalling may regulate the biology of adult human airway BCs relevant to COPD. BMP4 signalling components in human airway epithelium were analysed at the mRNA and protein levels, and the differentiation of BCs was assessed using the BC expansion and air-liquid interface models in the absence/presence of BMP4, BMP receptor inhibitor and/or small interfering RNAs against BMP receptors and downstream signalling.

Loss of tumor-derived SMAD4 enhances primary tumor growth but not metastasis following BMP4 signalling

Project description:We have reported previously that in preclinical models, BMP4 is a potent inhibitor of breast cancer metastasis and that high BMP4 protein levels predict favourable patient outcome. Here, we investigated the requirement for functional SMAD4 in mediating the anti-metastatic response of BMP4, given reports of promotion of metastasis by BMP4 in cancers where SMAD4 is frequently deleted. BMP4-induced inhibition of metastasis does not require functional SMAD4 in tumor cells. However, tumor cell intrinsic signalling using a constitutively active BMP receptor does require functional SMAD4 to suppress metastasis, thus implicating BMP4 mediated paracrine signalling as a contributor to the inhibition of metastasis.

Effect of BMP4 and noggin on gene expression in murine R1 ES cells

Project description:To confirm that the SMAD1/5- and SMAD4-associated genes are direct transcriptional regulators in mESCs in response to BMP, we treated undifferentiated R1 ES cells with BMP4 or with the BMP4 antagonist noggin, which can inhibit BMP signaling effectively for 4 h. Undifferentiated R1 ES cells were treated for 4 h with BMP4 or with the BMP4 antagonist noggin, which can inhibit BMP signaling effectively. Untreated R1 ES cells served as the control.

Distal-to-Proximal Re-patterning of Small Airway Epithelium in Smoking-associated Chronic Obstructive Pulmonary Disease

Project description:The proximal-distal patterning program determines unique structural and functional properties of proximal and distal airways in the adult lung. Based on the knowledge that remod-eling of distal airways is the major pathologic feature of chronic obstructive pulmonary disease (COPD), and that small airway epithelium (SAE), which covers distal airways, is the primary site of the initial smoking-induced changes relevant to COPD pathogenesis, we hypothesized that in COPD smokers, the SAE transcriptome loses its region-specific biologic identity and takes on the transcriptional pattern of the proximal airways. By analyzing human airway epithelium col-lected by bronchoscopic brushings from proximal and distal airways of healthy smokers, proxi-mal and distal airway epithelial transcriptome signatures were identified. Dramatic smoking-dependent suppression of distal signature paralleled by acquisition of the proximal airway epithe-lial phenotype was found in the SAE of COPD smokers. Distal-proximal re-patterning observed in the SAE of smokers in vivo was reproduced in vitro by stimulating SAE basal cells (BC), the stem/progenitor cells of the SAE, with EGF, a growth factor up-regulated in airway epithelium by smoking. Together, this study identifies distal-proximal SAE re-patterning as a characteristic feature of small airway disordering in COPD smokers potentially driven by EGF/EGFR-mediated reprogramming of SAE BC stem/progenitor cells.

The effect of BMP4/6 stimulation on adult muscle stem cells (MuSC)

Project description:Muscle development and regeneration strongly depends on extracellular cues and growth factors, which are taken up by muscle stem cells and guide them either towards proliferation and fusion or towards quiescence. Here we investigated the effect of bone morphogenetic protein (BMP) signaling on Pax7 positive adult muscle stem cells of the mouse. We discovered a cross talk between the BMP- and NOTCH-signalling pathways, leading to high upregulation upon BMP4/BMP6-stimulation of Hes1 mRNA which is a key component of the NOTCH-siganling pathway.
