5′tsRNA-Gly-GCC targets 3′UTR of Sirt6 mRNA. (A) An illustration of the putative site of 5′tsRNA-Gly-GCC binding within the 3′UTR of Sirt6 predicted by bioinformatics software RNAhybrid, with green used to highlight those nucleotides mutated for a mutant version of this sequence. (B) Luciferase activity assay revealed that 5′tsRNA-Gly-GCC mimic transfection into Hepa1-6 cells resulted in a 40% reduction in luciferase activity for constructs containing a WT but not a mutated version of this 3′UTR of Sirt6 binding site (n = 7). (C) Luciferase activity assay revealed that 5′tsRNA-Gly-GCC inhibitor transfection into Hepa1-6 cells significantly increased WT Sirt6 3′UTR activity, while 5′tsRNA-Gly-GCC inhibitor also had no significant effect on MUT Sirt6 3′UTR (n = 7). ****p < 0.0001.
