Trypsinization of the cells and replating for 24 h in the same volume of medium (total amounts of cells) but at lower surface density to reduce intercellular contact, did not modify the killing potentiation observed after delayed plating.
After 24 h, culture medium was replaced with treatment medium (total volume of 3.0 ml per well).
Ten healthy male and four healthy female subjects received 45 tablets of either P. freudenreichii ET-3 culture medium (total daily intake of 3 g solid content and 283.5 μg of DHNA; active group) or placebo (unfermented product) during two 1-week supplementation periods separated by a 4-week washout period.
Moreover, in cellulase-inducing medium total protein secretion of the VHb expressing strain was 2.2-fold of the parental strain and the filter paper cellulase activity was increased by 58% under oxygen-limiting conditions.
For transfection experiments, 3 µg of plasmid DNA and 10 µl of Cellfectin (Life Technologies) were combined in 200 µl of serum-free Grace medium (Life Technologies) for 30 min. Immediately prior to transfection, 3×10 cells in 800 µl of Grace medium were prepared and incubated with the transfection medium (a total of 1 ml culture) overnight in a 24-well suspension culture plate (Sarstedt).
To compare SE maintenance on each basal medium, a total of 15 SEs were combined into a group (replicate), with four groups per dish and three dishes per medium treatment (i.e., 12 replicates).
Flux balance analysis shows that, in YE medium, a total of 57 reactions involving NADPH have fluxes (Additional file 5).
Excluding genes differentially expressed between LNCaP/Co and LNCaP/IL-6#1 cultured in the standard medium, a total of 223 genes were found to be differentially expressed in LNCaP/IL-6#1 at least 2.0-fold greater or 2.0-fold less than those of LNCaP/Co under an androgen-deprived condition.
Autophagic sequestration was blocked by using the purine derivative, 3-methyladenine (3MA) (Enzo Life Sciences/Biomol International, BML-AP502), or the specific phosphatidylinositol (PtdIns) 3-kinase inhibitor, wortmannin (Enzo Life Sciences/Biomol International, BML-ST415) as described., Cells were treated with 5 mM 3MA or 50 µM wortmannin in normal growth medium (a total of 5hrs each).
Add additional 8 ml of complete medium (resulting in total of 10 ml complete medium).
