mRNA expression profile in DLD-1 and MOLT-4 cancer cell lines cultured under Microgravity
Description
DLD-1 and MOLT-4 cell lines were cultured in a rotating cell culture system to simulate microgravity and mRNA expression profile in comparison to Static controls. Cells were grown in 10mL rotating vessels in a Rotary Cell Culture System (RCCS) and in 60mm Petri dishes (test control respectively). Two replicates of test (Microgravity) and control (static) each from DLD-1 and MOLT-4 were analyzed by microarray. Simulated microgravity affected the solid tumor cell line DLD-1 markedly which showed a higher percentage of dysregulated genes compared to the hematological tumor cell line MOLT-4. Microgravity affects the cell cycle of DLD-1 cells and disturbs expression of cell cycle regulatory gene networks. Multiple microRNA host genes were dysregulated and significantly mir-22 tumor suppressor microRNA is highly upregulated in DLD-1.
