Cross-kingdom inhibition of breast cancer growth by plant miR159 - 0 views
-
MicroRNAs (miRNAs), a major family of small RNAs, are ∼23 nt-long single strands of RNA that bind to mRNA transcripts to inhibit their translation
-
A recent study by Zhang et al. reported that plant-derived miRNAs can be found in human serum.

The group demonstrates that the plant miRNA miR168 may be taken up through dietary intake to inhibit the expression of its target low-density lipoprotein receptor 1 in the liver21, providing the first evidence that miRNA in food may influence gene expression in mammalian organs.
