A microRNA network regulates proliferative timing and extracellular matrix synthesis during cellular quiescence in fibroblasts

Abstract excerpt

BACKGROUND: Although quiescence (reversible cell cycle arrest) is a key part in the life history and fate of many mammalian cell types, the mechanisms of gene regulation in quiescent cells are poorly understood. We sought to clarify the role of microRNAs as regulators of the cellular functions of quiescent human fibroblasts. RESULTS: Using microarrays, we discovered that the expression of the majority of profiled...
