Introduction

Small RNA is a kind of endogenous non coding RNA with regulatory function, mainly including miRNA, piRNA and siRNA. It induces gene silencing, participates in post transcriptional regulation, and play an important regulatory role in development, virus defense, hematopoiesis, organ formation, fine proliferation and apoptosis.
