Characterisation of sperm piRNAs and their correlation with semen quality traits in swine

6 monthes ago   |   By Animal Genetics

Summary
Piwi‐interacting RNAs are a class of non‐coding RNAs that are essential in the transcriptional silencing of transposable elements and warrant genome stability in the mammalian germline. In this study, we have identified piRNAs in porcine sperm using male germline and zygote datasets from human, mice, cow and pig, and evaluated the relation between their abundances and sperm quality traits. In our analysis, we identified 283 382 piRNAs, 1355 of which correlated with P ≤ 0.01 to at least one semen quality trait. Fifty‐seven percent of the correlated piRNAs mapped less than 50 kb...
