Project description:Mechanical forces are essential for normal fetal lung development. However, the cellular and molecular mechanisms regulating this process remain largely unknown. In the present study, we used oligonucleotide microarray technology to investigate gene expression profile in cultured E19 rat fetal lung type II epithelial cells exposed to a level of mechanical strain similar to that observed in utero. Significance Analysis of Microarrays (SAM) identified 92 genes differentially expressed by strain. Interestingly, several members of the solute carrier family of amino acid transporters, genes involved in amino acid synthesis and development, and amiloride-sensitive epithelial sodium channel gene were induced by strain. These results were confirmed by quantitative real-time polymerase chain reaction (qRT-PCR). Thus, this study identifies genes induced by strain that may be important for amino acid signaling pathways, protein synthesis and development in fetal type II cells. In addition, these data suggest that mechanical forces may contribute to facilitate lung fluid reabsorption in preparation for birth. Taken together, the present investigation provides further insights into how mechanical forces may modulate fetal lung development.

Project description:Mechanical force is critical for lung development. In this study we identified specific EV-miRNAs released from the mouse epithelial cell line in response to mechanical stretch involve in lung development. In utero fetal lung experiences significant continuous transpulmonary pressure as a result of epithelial secretion in to the airway lumen, and periodic fetal breathing movement that move the fluid along the developing airway. Mechanical force is important factors for fetal lung development. However, the effect of mechanical force on the functions of lung cells is not known precisely. Extracellular vesicles –microRNAs (EV-miRNA) are increasingly recognized as a new mode of cell-to-cell communication. miRNA is well known as a regulator of physio-pathological process. In this study, we used oligonucleotide microarray technology to investigate miRNA expression in EV-released from mouse lung epithelial cell MLE12 after exposed to 10% cyclic or 5% continuous stretch. Analysis of microarray data identified 9 and 33 miRNAs significantly differentially expressed by the cyclic and continuous stretch respectively. Several differentially expressed miRNAs were reported dynamically expressed in mouse developing lung. miRNAs associated with important transcription factors for cell function and key signaling pathways for fetal lung development also identified in this study. We conclude that mechanical signals differentially regulate the expression of specific EV/miRNAs in MLE12 are important for intercellular communication during lung fetal development.

Project description:Inflammation is a key component of pathological angiogenesis. Here we induce cornea neovascularisation using sutures placed into the cornea, and sutures are removed to induce a regression phase. We used whole transcriptome microarray to monitor gene expression profies of several genes
