" ncRNAs have recently been implicated in Lamarckian transmission of inherited characteristics. In one example, fertilised mouse eggs were injected with a miRNA which targeted a key gene involved in growth of heart tissue. The mice which developed from these eggs had enlarged hearts (cardiac hypertrophy) suggesting that the early injection of the miRNA disturbed the normal developmental processes. Remarkably, the offspring of these mice also had a high frequency of cardiac hypertrophy. This was apparently because the abnormal expression of the miRNA was recreated during generation of sperm in these mice. There was no change in the DNA code of the mice, so this was a clear case of a miRNA driving epigenetic inheritance "
