Figure 8From: 5′ tRNA halves are present as abundant complexes in serum, concentrated in blood cells, and modulated by aging and calorie restrictionTissue distribution of tRNA-Val-CAC halves. Northern blotting analysis of RNA extracted from the indicated mouse tissues. Blots were hybridized with 32P-end-labeled oligonucleotide probes complementary to the 5′ (A, B, and D) or 3′ end (C and E) of tRNA-Val-CAC. The positions of full length tRNAs and tRNA halves are indicated on the right. DM: decade markers.Back to article page
