miR-337 overexpression suppressed the invasion of malignant T cells. After miR-337 plasmid transfection, the invasion capacity of MyLa2059, PB2B, and SeAx cells was measured using a transwell migration assay (a, b, c) and the number of invasive cells was counted (d, e, f). Representative data are expressed as mean ± SD. *P < 0.05, **P < 0.01. n = 3.
