This was in contrast to FL CA9 mRNA, which was clearly hypoxia-inducible and showed considerably increased levels, namely in Caski, SiHa, and ACHN cells, whereas CAKI-1 cells expressed only a very low level of FL CA9.
Pdc1,5,6 triple mutants expressed only a very low KDC activity (8.66 ± 0.41 mU mg protein-1) whereas the wild-type strain exhibited the highest activity (38.73 ± 6.24 mU mg protein-1).
However, landmarks express only a very small proportion of the information available from the images.
While it is possible that our translational fusion did not recapitulate the entire nhr-239 expression pattern, this result suggests that nhr-239 is expressed only in a very limited subset of neurons.
The p75NTR is expressed only on a very low percentage of NK cells.
According to Jaakola et al. [ 7], VmANS is expressed only at a very low level in bilberry fruits at the early stage of fruit development.
Although EpCAM, CD133, CD24 and CD44 were expressed in all three subpopulations of Li-7 cells in vitro (Additional file 2: Figure S2), interestingly, they were expressed only in a very low proportion of tumor cells expressing CD13 in vivo.
Surprisingly, when we searched from approximately 63,400 macaque brain and testis cDNAs, we found only three testis clones that were homologous to Hs XRRA1, suggesting that the Mf XRRA1 gene is expressed only at a very low level in brain.
The cellular junction marker protein ZO-1 showed the same level of expression in hCMEC/D3 and hBMEC cells, but was expressed only at very low levels in BB19 and TY10 cells.
As a quality control step to eliminate background noise from genes that are not expressed (or expressed only at very low levels) in adult females, we required that a spot have mean signal intensity at least one SD above local background in both channels to be included in the analysis.
The two forms of the protein exhibit differential expression patterns: RORB2 is found exclusively in the retina and pineal gland, and RORB1 is found mainly in the cerebral cortex (particularly in layer IV and, to a lesser extent, layer V), thalamus, and hypothalamus and is expressed only at very low levels in the retina and pineal gland [ 39, 40].
