Project description:We investigated differentially regulated and stably expressed genes in human Jurkat T lymphocytic cells in 5min simulated microgravity and hypergravity and compared expression profiles to identify gravity-regulated and unaffected genes as well as adaptation processes.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Physical forces greatly influence the growth and function of an organism. Altered gravity can perturb normal development and induce corresponding changes in gene expression. Understanding this relationship between the physical and biological realms is important for NASA’s space travel goals. We use combined RNA-Seq and qRT-PCR to profile changes in early Drosophila melanogaster pupae exposed to chronic hypergravity (3 g, three times Earth’s gravity) to highlight gravity-dependent pathways and gene products. Robust transcriptional response was evident among the pupae developed in a hypergravity environment compared to control. 1,513 genes showed significantly (p < 0.05) altered gene expression in the 3 g samples. These findings were supported with qRT-PCR data. Major biological processes affected include ion transport, redox homeostasis, immune and humoral stress response, proteolysis, and cuticle development.
