Glucose regulates RMI1 expression through the E2F pathways in adipose cells.

RecQ-mediated genome instability 1 (RMI1) has been identified as a novel energy homeostasis-related molecule. While recent studies have suggested that change in RMI1 expression levels in adipose tissue may affect the body's energy balance, no reports have identified the mechanism behind this expression regulation. In the present study, we found that RMI1 expression increased on differentiation of 3T3-L1 fibroblasts to adipocytes. In addition, glucose stimulation induced RMI1 expression to approximately eight times the baseline level. Further, knockdown of either E2F5 or E2F8 mRNA using siRNA suppressed this glucose-induced up-regulation of RMI1 expression. These results suggest that RMI1 expression may be regulated by glucose, at least in part, via E2F expression.
