RNA G4s are enriched in important regulatory regions of RNAs thus potentially implicating them in different aspects of RNA metabolism. (grantome.com)

Our findings with PinT and other intracellularly induced [small RNAs] illustrate how small perturbations in the infection process, such as dysregulation of a few Salmonella mRNAs, can propagate through the entire host system, potentially leading to different disease outcomes in the context of a whole organism," the researchers concluded.

To cap- lular phenotypes (e.g. disease) on a mechanistic level, and ture the complex network of nonlinear information process- to use genomic signals to classify disease on a molecular ing based upon multivariate inputs from inside and outside level. (lu.se)
Genomic signal processing (GSP) is the discipline that studied and developed--in particular, estimation, classifi- studies the processing of genomic signals. (lu.se)
We describe structure-guided engineering of a CRISPR-Cas9 complex to mediate efficient transcriptional activation at endogenous genomic loci. (cdc.gov)

The current data support previous findings and recapitulate transcriptional regulatory alterations in genes involved in sleep, auditory function, and pain. (frontiersin.org)

Thus, A-to-I editing in both translated and untranslated regions of RNA can be biologically significant. (biomedcentral.com)

The reclassification is based on the degree of homology of RNA oligonucleotides between groups. (medscape.com)

In this chapter, we will discuss the involvement of post-transcriptional events, such as RNA processing, the action of non-coding RNAs and RNA decay in cancer development, and how their machinery may be used in cancer diagnosis and treatment. (intechopen.com)

Today, RNA-controlled regulatory processes are broadly recognized for a variety of ncRNA classes. (qucosa.de)
Eukaryotic regulatory RNAs are broadly classified into lengthy (200 nt) and little (200 nt). (angiotensinreceptor.com)

RNA which contains an intron sequence that has an enzyme- like catalytic activity. (genomicglossaries.com)
Cas9 nuclease can be converted into an RNA-guided DNA binding protein (dCas9) via inactivation of its two catalytic domains 12 , 13 and then fused to transcription activation domains. (cdc.gov)
