Fig. 6From: Long non-coding RNA TUG1 is up-regulated in hepatocellular carcinoma and promotes cell growth and apoptosis by epigenetically silencing of KLF2TUG1 negatively regulates expression of KLF2 by rescue assays. a,b Colony-forming assays were used to determine the cell viability for HepG2 cells transfected with si-NC,si-TUG1-1# and co-transfected with si-TUG1-1# and si-KLF2. Values represent the mean ± s.d. from three independent experiments. c MTT assays were used to determine the cell viability for HepG2 cells transfected with si-NC,si-TUG1-1# and co-transfected with si-TUG1-1# and si-KLF2. Values represent the mean ± s.d. from three independent experiments. d,e The levels of KLF2 protein levels were determined by Western Blotting when HepG2 cells transfected with si-NC, si-TUG1-1# and co-transfected with si-TUG1-1# and si-KLF2Back to article page
