Addition of UCN-01 after IR resulted in a further significant reduction in cell yield compared to IR alone in the HT29 and SW480 cell lines (P<0.05, Figure 1a,c).
In addition to the reduction in cell viability seen at baseline, application of oxidative stress in the form of 100 μM hydrogen peroxide for 48 hours resulted in a further significant decrease in cell viability during the MTS assay in AAAS-KD H295R cells (absorbance readings 0.38 ± 0.01; mean ± SD) compared with untreated knockdown cells (0.43 ± 0.01) (P <.01, n = 3).
Furthermore, it was found that addition of HC to the medium resulted in a further significant reduction in cell migration.
Localized regions of apoptosis were seen in the anterior-most epithelium of the wild-type maxillary incisors, although further posteriorly no significant cell death was visible within the body of the developing cap itself (Fig. 9B,D).
Moreover, compared to EX527 or GEM alone, treatment with a combination of both resulted in further significant increase of cells in G0/G1 phase (84.39 ± 1.30%, P < 0.01).
Instead, during the stimulation period, a further significant regression in the cell numbers of both cell types was observed (Supplementary Figure 3).
Intriguingly, the combination of QLT0267 plus 6 Gy showed a further significant (P<0.01) accumulation of cells in the G2 phase under 2D but not under 3D growth conditions (Figure 4B).
A further significant decrease in percentage of cells in early apoptosis was seen at 72 h.
In serum-free medium, the MCF-7 cell number declined over 5 days in culture and, in contrast to the findings above, Δ1 9 induced further significant reductions in the MCF-7 cell number of 5%to10%0% over controls, at concentrations >10 ng/ml.
RAD51-depleted cells exhibited a further significant increase in the average deletion length (22 bp, p = 0.014).
As transduction of PDLSCs using an adenovirus vector carrying the P2X7R gene (Ad-P2X7) at 50 pfu/cell (multiplicity of infection (MOI) = 50) or 100 pfu/cell (MOI = 100) resulted in significant cell death, we excluded these two concentrations in further experiments.
