Sentence examples for repression mechanisms from inspiring English sources

The high levels of de-repression in the absence of Tup1p suggest that this subset of genes is predominantly repressed by Cyc8 Tup1 without possible compensatory repression mechanisms; in the absence of the co-repressor these genes are constitutively switched on.

In a cell line derived from the central nervous system, cohesin and the PRC1 PcG protein complex bind and repress E (spl -C transpl -Cion, butranscriptionion mechanisms are unknown.

Potential carbon catabolite repression mechanisms and novel expression patterns of promoters were unfolded.

Massive rib gene overexpression was attained by interfering with the natural repression mechanisms of rib gene expression, usage of strong heterologous promoter elements, and by increasing the rib gene copy number.

As noted above, Gro probably functions via multiple repression mechanisms.

It thus appears that either of the two established transcriptional repression mechanisms is sufficient for RB to inhibit cell proliferation.

Chd activation may be mediated in part by a double repression mechanism, whereby Gsc represses Vents which in turn repress Chd expression (Melby et al, 1999).

Moreover, in the presence of glucose as carbon source the gene for carbon dioxide fixation could be repressed due to a carbon catabolite repression mechanism [ 71].

In the experiment using a stable transfectant of Snail or SIP1 in HepG2 and Huh-7 cells, E-cad expression was dramatically repressed, supporting the previous reports of E-cad repression mechanism by Snail and SIP1.

Microorganisms generally metabolize sugars sequentially when exposed to a mixture of glucose and xylose, because glucose can repress the utilization of other sugars via a catabolite repression mechanism or allosteric competition for sugar transporters [ 6].

Cellulases are inducible enzymes and the regulation of the cellulase production is finely controlled by activation and repression mechanism.
