Over-expression of miR-377 suppressed colon cancer stem cell phenotype
and EMT via repression of ZEB2. (A) Effect of miR-377 and ZEB2 on the
protein expression of ZEB2, ALDH1, CD133, E-cadherin, N-cadherin and
vimentin in HCT116 cells was detected by western blot. ** represents
miR-377 + Vector vs. Control + Vector,
P < 0.01. ## represents miR-377 + Vector
vs. miR-377 + ZEB2, P < 0.01.
(B) Effect of miR-377 and ZEB2 on the percentage of ALDH+
cells detected by flow cytometry sorting. ** represents miR-377 + Vector
vs. Control + Vector, P < 0.01.
## represents miR-377 + Vector vs. miR-377 + ZEB2,
P < 0.01. (C) Effect of miR-377 and ZEB2 on the
self-renewal of spherogenic HCT116 cells was detected by sphere
formation assay. ** represents miR-377 + Vector vs.
Control + Vector, P < 0.01. ## represents miR-377 +
Vector vs. miR-377 + ZEB2, P <
0.01. (D) Effect of miR-377 mimics and ZEB2 overexpression on HCT116
cell migration was detected by wound healing assay. ** represents
miR-377 + Vector vs. Control + Vector,
P < 0.01. ## represents miR-377 + Vector
vs. miR-377 + ZEB2, P < 0.01.
