It has been shown that long non-coding RNAs LncRNAs play an important role in the development of human cancers. This study aims to investigate the effect of LncRNA. Carcinogenic mutagenic and reprotoxic substances are often referred to as a group due to the fact that a substance may present all three types of hazards but also due to similarities in classification and in legal approach.
