Effects of 3-D clino-rotation on gene expression in human fibroblast cells.

Abstract:

:Continuous variation in the direction of the gravity vector leads to various cellular responses including modulation of gene expression. Complementary DNA (cDNA) array analyses are available to observe the variation of gene expression under different conditions. In this study, expression levels of 588 representative genes were compared using the Atlas human cDNA expression array in human fibroblast cells with and without 3-dimensional (3-D) clinostat. Five upregulated and 8 downregulated genes were detected. Among these genes, upregulation of XRCC1, and downregulation of ERB-B2 and p21(Cip1/Waf1) were confirmed by RT-PCR. These results suggested that the gene expression levels of XRCC1, ERB-B2 and p21(Cip1/Waf1) were modulated by vector-averaged microgravity induced by 3-D clinostat in human fibroblast cells. Our findings may be a basis for the biological study of 3-D culture systems.
