AGT and alkaline phosphatase measurement: Especially, one novel tsRNA tRF3‐Thr‐AGT was significantly downregulated with biggest fold changes (Fold change = −167.04, p < 0.0005) after STC stimulation (Figure 1B), and the following bioinformatics analysis suggested that the potential downstream targets of tRF3‐Thr‐AGT were associated with AP progression (Figure S1).
