JAK2 and hemoglobin measurement: Furthermore, we found that the biological effect of miR-181b-5p on HB metastasis is mediated by the inhibition of SOCS2 and the activation of the JAK2/STAT5 signalling pathway, suggesting that miR-181b-5p may serve as a therapeutic target for HB patients (Lv et al., 2023a; Lv et al., 2023b).
