Therefore, our study demonstrated that miRNA-mRNA interactions not only took place in cytoplasm but also in nucleus. (biomedcentral.com)
25 BARD1 also regulates the subcellular localisation of BRCA1, both by translocating BRCA1 into the nucleus and by inhibiting its nuclear export. (bmj.com)

The nucleotide sequence was determined with an automated DNA sequencer. (cdc.gov)

Many different human diseases can be caused by errors in RNA splicing or its regulation. (ox.ac.uk)
These data suggest that FECR1 circular RNA acts as an upstream regulator to control breast cancer tumor growth by coordinating the regulation of DNA methylating and demethylating enzymes. (biomedcentral.com)

The introns containing these large expansions are transcribed and indeed in patients the GGGGCC-repeat expansion is detectable by in situ hybridization in nuclear RNA foci 5 . (nature.com)

Also, viral infection has proved to have a great impact on cellular small RNA expression and gene expression [ 9 - 11 ]. (hindawi.com)

Small RNAs include microRNA (miRNA), siRNA, tRFs, piRNA, and rasiRNAs, which regulate gene expression in a wide range of processes such as viral replication and host immune response. (hindawi.com)

Therefore, the level of Cab mRNA, as measured by the presence of sequences hybridizing to a cDNA probe, does not limit the rate of chlorophyll accumulation after transfer of pea seedlings to white light. (ncsu.edu)
Sequencing of tags created by restriction digestion of cDNA generates gene expression profiles with an absolute count (from one to a few million) of the RNA in the sample. (elimbio.com)
However, it is difficult to capture the complexity of transcript isoform variance using these libraries, and large cDNA sequences are often difficult to clone into size-limited viral expression vectors. (cdc.gov)

Transient expression of heterologous RNAs using tomato golden mosaic virus. (ncsu.edu)
One problem with identifying binding sites for splicing factors arises from the transient role of RNA in gene expression. (nih.gov)

This study contributes to the understanding of the mechanism of viral RNA packaging and replication. (cuny.edu)
This research project focuses on characterizing the anti-double stranded DNA (dsDNA) response in mice that express the viral Epstein Barr Nuclear Antigen-1 (EBNA-1). (cuny.edu)

To expand understanding of the role of snoRNAs in control of gene expression, in this study we tested the ability of artificial box C/D RNAs to affect the maturation of target pre-mRNA. (hindawi.com)
In that case, snoRNAs hold two potential guide sequences [ 2 , 4 ]. (hindawi.com)

The other two forms of RNA, ribosomal RNA (rRNA) and transfer RNA (tRNA), are involved in the process of ordering the amino acids to make the protein. (dekooktips.com)
Amino acid sequences were translated from coding sequences and aligned by BioEdit ( 6 ). (cdc.gov)
Their binding properties depend on the amino acid sequence of the finger domains and of the linker between fingers, as well as on the higher-order structures and the number of fingers. (embl.de)
The MOG1 domain required for the interaction with Nav1.5 to the region spanning amino acids 146-174, and a refined deletion analysis further narrowed this domain to amino acids146-155. (nih.gov)

RNA processing in chloroplasts includes mRNA 5′- and 3′-end processing, intron splicing, and intercistronic cleavages of polycistronic messages, as well as typical tRNA and rRNA processing. (dekooktips.com)
They are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). (dekooktips.com)
There are three types of RNA: mRNA, tRNA, and rRNA. (dekooktips.com)
There are three types of RNA involved in the translation process: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). (dekooktips.com)
The three main types of RNA directly involved in protein synthesis are messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). (dekooktips.com)
Messenger RNA (mRNA), transfer RNA (tRNA) and ribosomal RNA (rRNA) are the three major types of RNA. (dekooktips.com)

Ideally, this should be done in the context of integrative biology in which all biotic members of the pathosystem, as well as the intricate interactions among them, are considered. (sisef.it)

These posttranscriptional steps, along with changes in RNA stability, have received considerable attention for two reasons. (dekooktips.com)
Polyadenylation is essential for the stability of the transcript, preventing the mRNA from being the target of posttranscriptional gene silencing (PTGS) via RNA-dependent RNA polymerase 6 (RDR6) in plants ( Luo and Chen, 2007 ). (frontiersin.org)

Understanding a biological interactions system demands understanding the details of its components, and their interactions. (biomedcentral.com)
Each class of small RNAs is synthesized by a distinct mechanism and each has discrete biological functions. (biomedcentral.com)

Although the in vitro acetylation assays revealed that HDAC5 decreased LSD1 protein acetylation, small interfering RNA (siRNA)-mediated HDAC5 knockdown did not alter the acetylation level of LSD1 in MDA-MB-231 cells. (johnshopkins.edu)

Similar analyses were performed for RNAs extracted from pea seedlings grown under several different light regimes. (ncsu.edu)
In vivo analyses of cis-acting sequence requirements for pre-mRNA splicing in tobacco nuclei have previously demonstrated that the 5′ splice sites are selected by their position relative to AU-rich elements within plant introns and by their degree of complementarity to the U1 small nuclear RNA.
