Metabolically active tumour tissue, as depicted by FET uptake, is represented to a low extent by the choline/N-acetyl-aspartate ratio measured by spatially resolved 3D MRSI, which is in contrast to previous findings.
It is highly up-regulated in metastatic and hormone-refractory prostate carcinomas, but its endogenous expression has also been reported in kidneys, salivary glands, small intestine, brain and, to a low extent, also in healthy prostate tissue [2],[3].
However, activity of PO was increased to a low extent in crayfish injected with the ΔwaaE mutant.
Instead, erythro-ascorbic acid, a structurally related compound with chemical properties very similar to those of L-AA, is the molecule occurring to a low extent in yeast cells [9].
Undifferentiated human mesenchymal bone marrow stem cells already express the neuronal lineage markers β-III-tubulin and GFAP, and the smooth muscle marker α-SMA to a low extent before any differentiation [84].
The analysis showed that positively selected cells were hardly detectable at 5 and only to a low extent at 30 minutes after transfer, while negatively selected cells were clearly detectable at both time points with a decreasing concentration probably reflecting the normal cellular turnover (Fig. 4A).
GLUT9 participates to a low extent to glucose influx into HepG2 cells (Takanaga et al. 2008).
We mutagenized the cells only to a low extent, followed by a strong selection.
All questions have five response categories (always; often; sometimes; seldom; never or, when appropriate: to a very large extent; to a large extent; partly; to a low extent; to a very low extent).
To generate high light tolerant mutants, wildtype cells were mutagenized only to a low extent, followed by a stringent selection.
