Expression of miR-216b was measured using StepOne Real-Time PCR System at 48 h after the cells reached confluence, while that of proteins was measured 72 h after the cells reached confluence.
At day 5, cells in IM and GM appeared about 90% confluence while those in CM gathered in to several rounded clumps.
The cells were passaged by trypsinization (Trypsin-EDTA) to disrupt cell monolayer at confluence while splitting RAW264.7 cells for the routine culture and plating the cells for the in vitro assays.
For instance, in Figure 2 the non-treated A2780R cells have a 55% confluence, while a 33% of confluence is observed when the cells are incubated with 6.17 μM of cisplatin.
Unusually, cldn-4 protein increased up to 4-fold at the 4th day after confluence, while its mRNA levels remained stable, suggesting a complex regulation that should be given at different levels.
Transgelin (TAGLN), a marker of the multipotent pericyte, was prominently expressed around confluence while adipogenic PPARγ was up-regulated already in subconfluent cells.
Among all the factors, we noticed that SOX2 significantly reduced cell proliferation: by day 3, OCT4, KLF4, cMYC and SV40LT transfected fibroblasts grew to 60 80% confluence, while SOX2 transfected cells were markedly less confluent (Fig. 4A c).
Nucleolin mRNA induction is reduced markedly in normal fibroblasts that reach confluence, while it occurs continuously even in post-confluent epithelial tumor cells consistent with their capacity to proliferate without contact inhibition.
Indeed, nucleolin mRNA induction is reduced markedly in normal fibroblasts that reach confluence, while it occurs continuously even in post-confluent epithelial tumor cells consistent with their capacity to proliferate without contact inhibition.
Stimulation of cells with ephrinB2 did not pose any significant effect on cell viability before reaching confluence, while inhibition of cell growth was detected after 6 days when cells were in postconfluent state following a dose-dependent manner.
