Project description:Lung cancer is one of the leading causes of death. However, most of the researches were based on the traditional cell-culturing method. Whereas cells of lung are subjected to the mechanical forces periodically while breathing. In the present study, we applied cyclic stretch to stimulate the continuously contracting physical condition. We uncovered the stretching force-induced phosphoproteome in lung cancer cell A549 and fibroblast IMR-90. 2048 and 2604 phosphosites corresponding to 837 and 1008 phosphoproteins were identified in A549 and IMR-90, respectively. Interestingly, cytoskeleton reorganization and mitochondrial localization were enriched in the significantly expressed phosphoproteins in response to cyclic stretch. Indeed, we found this physical stress changed cell alignment thus disrupted mitochondrial dynamics. We proved that mitochondrial fusion is induced by uniaxial stretch in 2 cell lines. This study reveals the molecular mechanism of cyclic stretch and supports that stretching force enhanced cellular rearrangement and mitochondrial fusion in lung cells.
Project description:Adenovirus type 2 RNA splicing sites were mapped by using deep cDNA sequencing. The majority of the previously identified splice sites were detected. In addition, novel splicing sites were identified Total RNA obtained from four time stages of human primary lung fibroblast cells IMR-90 infected by adenovirus type 2 compared to the control mock-infected by adenovirus type 2.
Project description:IMR-90 Human Fibroblasts were seeded onto TCPS dishes. mRNA was isolated at 1, 2, 4, 8, 12, 24, 48 and 96 hours. This time course was used as a control for gene expression studies on collagen/chondroitin sulfate tissue engineering scaffold materials using the same cell line.
