Research Abstract

The novel concept “chronic impairment of microRNA function due to chronic inflammation may cause inflammation-associated tumorigenesis” was identified. Drug library screening revealed a compound which enhances microRNA function. This compound indeed had preventive effects against inflammation-associated tumorigenesis. These results may open a new strategy to prevent inflammation-associated tumorigenesis.
