miRNA-768-3p negatively affects PTCL growth. (A) Cell growth was monitored for 4 days in miRNA-768-3p- or miRNA negative control–transfected FEPD cells using a MTS proliferation assay. (B) Cell-cycle distribution in miRNA-768-3p-, miRNA-768-3pM-, or miRNA⁻ control-transfected FEPD cells. (C) Cyclin A expression was analyzed by Western blot in the 3 conditions described in panel B. A paired t test was used to analyze the statistical significance of the results. *P < .05; **P < .01; ***P < .001.
