According to the preliminary bioassay results, some of the title molecules have been demonstrated to exhibit good inhibitory activities against all three lung cancer cell lines, so in order to further explore the potential activities, the IC50 values were investigated based on the above cell-based method.
The ability to distinguish cell lines so accurately represents significant progress for metabolic phenotyping of cancer cells and forms a basis for profiling differing tumor backgrounds as well as shared and non shared drug responses.
It is desirable that future studies include different cell lines, so that cell-line-specific effects can be excluded.
Protein detection of H- and A-FABP was not possible in all cell lines, so that differences between mRNA and protein expression appeared there, too.
(30) However, the MDA-MB-231 and BT-549 cells are p53 mutated cell lines, so in these cells, the upstream regulator of miR-200c might not be p53.
This panel of cell lines contained only six ovarian cancer cell lines, so instead of comparing our data to this small subset of cells, we compared data for the entire panel.
In general, the surgical glioma samples had reduced phosphoprotein expression levels compared to cultured cell lines, so a higher total protein concentration was used for all tumor samples (150 μg/mL).
Cells were seeded in triplicate into six-well plates or a 25-cm flask in a range of 100 80 000 cells per well, depending on the radiation dose that the cells received, the test condition, and different cell lines, so as to yield 20 200 colonies per flask or well).
This corresponds to check for the maintaining of a stable differentiation rate across cell lines, so that their mutual distances (in terms of 1-r metrics with r the Pearson correlation coefficient), even if increasing during differentiation process, maintain their relative proportions.
A dose-dependent growth inhibition was observed following treatments with MSeA in both cell lines more so in hypoxia than in normoxia yet for PC3 cells growth inhibition was significant at 5 μmol/L but not at 10 μmol/L between normoxia and hypoxia while the same trend was observed in PC-3M cells yet significant inhibition was observed only 10 μmol/L MSeA (Fig. 3B).
