Sentence examples for repression I from inspiring English sources

Because the Shh receptor Ptch1 is not expressed at the ZLI, it is likely that this activation and enhancement involve double repression, i.e., Ptch1 receptor activation likely represses Dbx1 and Lhx5, and so loss of Ptch1 in the ventricular zone at the ZLI would allow expression of Dbx1 by progenitors and Lhx5 by their progeny.

We present our optimized techniques and data from studies that measure specific and direct repression (i.e. negative regulation) of mRNAs by members of the PUF family of RNA binding proteins in cultured human cells.

Once recruited to a gene, Gro typically directs long-range repression, i.e., it silences promoters with little regard for the distance between the point of Gro recruitment and the promoter or between the point of Gro recruitment and the enhancers directing activation of the promoter [14].

N quantifies the binding cooperativity of FRQ repression; i.e. the number of sites on the FRQ promoter that can be bound by FRQ molecules to prevent transcription.

Although there is a trend for each strain to similarly exhibit more gene de-repression (i.e. overexpression) than repression (i.e. under-expression), the expression patterns for the chdA, chdB and chdC nulls display distinct gene expression profiles, underscoring their unique developmental phenotypes.

In addition, the strength of the repression, i.e the concentration of the preferred substrate in the medium under which the repression is fully operating, can greatly differ depending of the regulatory circuit of the second substrate usages.

This growth most likely occurred due to de-repression (i.e., increase) of growth hormone gene expression.

Alfred is an open-and-shut case of anality and sexual repression (and I guess I should admit that the R. Crumb-like talking feces he hallucinates may not be the book's subtlest moment), yet he's silently self-sacrificing, and admirable in his rigorous work ethic and fidelity.

However, at MAD1, CRYZ and ANLN promoter sites, we observed an increased hypermethylation of both the repression marks, i.e. H3K9me3 and H3K27me3.

In contrast, CDC25c promoter showed increased hypermethylation for H3K27me3 residue without any significant changes for the other repression mark, i.e. H3K9me3.

In particular, we estimated significance of the CAD repression to: i. the lignin level in fibre; ii. the composition and structure of cell wall; iii. the phenotype of modified plants in vivo; iv. the properties of flax fibre.
