Also fibroblasts surrounding normal ducts expressed low amounts of ST-3, indicating a low level basal expression of the protein.
These 3D microtissues remain viable and stable throughout the 8-day testing period and relative to 2D monolayers, show increased basal expression of the xenobiotic metabolizing enzyme cytochrome P450 1A (CyP450.
From the collected data, we first analyzed the basal expression of the screened genes in untreated MDM and PBL.
Granulocyte enriched fractions showed high basal expression of the genes for CXCa_L1, CXCb and CXCR1 (Fig. 3c).
The higher basal expression of the Cyp genes is most likely due to loss of suppression by endogenous Fgf15 protein.
Therefore, liver denervation per se does not affect the basal expression of the different genes studied, confirming our previous study [28].
In our analysis, we observed a large and significant difference in the basal expression of the CGA mRNA in autumn vs. spring.
The lower synthesis of HmgB protein in B. xenovorans LB400 grown in glucose indicates a basal expression of the catabolic hmgB1 gene during growth on this carbon source.
As the MTL50 value of each gene is calculated relative to appropriate unsilenced controls, differences in basal expression of the different essential genes will not affect the stringency ranking.
The fact that hilD expression level in the UA1888 (PhilD, DPD addition), UA1889 (PhilD*), and UA1890 (Δfur) strains were similar suggests that inactivation of BoxA (in PhilD*) had no effect on basal expression of the gene.
A significant fraction of the cell population appeared to exhibit basal expression of the reporters, supporting the hypothesis that there are at least two distinct subpopulations of cells within the cycling population.
