AKT1 and systemic lupus erythematosus: ADSC and miR-20a-ADSC treatment resulted in the upregulated expression of miR-20a and inhibited the phosphorylation of Akt and mTOR compared with the lupus group, and the miR-20a group had a much stronger effect compared with the ADSC group (all P < 0.05; Figure 3).
