Systematic analysis of tRNA-derived small RNAs in liver, spleen and small intestine of intrauterine growth retarded and normal pigs

tRFs (tRNA-derived small fragments) are a new class of small non-coding RNAs reported in recent years, with biological functions similar to microRNAs. In this study, we analysed the expression of tRFs in the liver, spleen and small intestine of intrauterine growth retarded (IUGR) and normal pigs using next-generation sequencing
