Effect of ptRNase-treatment on tRF levels in wild-type and ΔRNH1 HeLa cells. (A) Principal component analysis of normalized tRF levels in ANG-, RNase 1-, or untreated cells. (B) Abundance of tRFs in ANG-treated ΔRNH1 cells. Values are the average of three biological replicates. (C) Abundance of tRFs in ANG-treated wild-type cells. (D) Predicted G-quadruplex forming motifs in up-regulated tRFs.
