Pity: The Importance Of Non Coding Rnas

The Importance Of Non Coding Rnas	Aug 25,  · Long non‐coding RNAs serve as pivotal regulators of genes that are able to generate LncRNA–binding protein complexes to modulate a great number of genes. Recently, the LncRNA urothelial carcinoma‐associated 1 (UCA1) has been revealed to be dysregulated, which plays a critical role in the development of a few cancers. 44 minutes ago · Background: Idiopathic Pulmonary Fibrosis (IPF) is a chronic degenerative disease with a median survival of 2–5 years after diagnosis. Therefore, IPF patient identification represents an important and challenging clinical issue. Current research is still searching for novel reliable non-invasive biomarkers. Therefore, we explored the potential use of long non-coding RNAs (lncRNAs) . 5 days ago · Long RNA molecules carrying DNA codes that don't get translated into proteins have long been a mystery of the human genome. Now, scientists at Duke-NUS Medical School have found a way to systematically investigate their functions and discovered some could play a role in pancreatic cancer. Their findings, published in the journal Genome Medicine, highlight the importance of investigating long.

Acute kidney injury AKI is one of the most common complications affecting hospitalized patients associated with an extremely high mortality rate. However, the underlying pathogenesis of AKI remains unclear that largely limits its effective management in clinic. Increasing evidence demonstrated the importance of long non-coding RNAs lncRNAs in the pathogenesis of AKI, because of their regulatory roles in transcription, translation, chromatin modification, and cellular organization. Abstract Acute kidney injury AKI is one of the most common complications affecting hospitalized patients associated with an extremely high mortality rate.

In a study found only one-fifth of transcription across the human genome is associated with protein-coding genes, [4] indicating at least four times more long non-coding than coding RNA sequences. It has been suggested through multiple studies that testis , [7] and neural tissues express the greatest amount of long non-coding RNAs of any tissue type. In comparison to mammals relatively few studies have focussed on the prevalence of lncRNAs in plants. In the landscape of the mammalian genome was described as numerous 'foci' of transcription that are separated by long stretches of intergenic space. The GENCODE consortium has collated and analysed a comprehensive set of human lncRNA annotations and their genomic organisation, modifications, cellular locations and tissue expression profiles. There has been considerable debate about whether lncRNAs have been misannotated and do in fact encode proteins. Several lncRNAs have been found to in fact encode for peptides with biologically significant function. However, further investigations into vertebrate lncRNAs revealed that while lncRNAs are conserved in sequence, they are not conserved in transcription. Some argue that these observations suggest non-functionality of the majority of lncRNAs, [43] [44] [45] while others argue that they may be indicative of rapid species-specific adaptive selection. While the turnover of lncRNA transcription is much higher than initially expected, it is important to note that still, hundreds of lncRNAs are conserved at the sequence level.

However, their roles and functions are significantly different from those of proteins. This observation is remarkable owing to the fact that this helicase is responsible for upregulating the hairpin loop.

This indicates that an inhibitory feedback mechanism acting on the p68 RNA helicase is Improtance by higher structural levels of the hairpin-loop. To validate our hypothesiswe directly compared p68 RNA sequences and the hairpin loop in silico. The effect of hairpin loop overexpression on cell growth and cancer processes was also investigated by analyzing cell-cycle phases and miR expression.

Finally, alternative splicing microarrays containing apoptosis targets were incubated to verify whether pre-mRNAs other than H-Ras could also present a similar hairpin loop structure regulated by p68 RNA helicase.

Moreover, a similar effect on p68 RNA helicase-mediated interference is observed during the upregulation of the hairpin loop. Thus it can be inferred from our findings that the alternative splicing exon IDX from H-Ras, coupled with the immediately downstream intron sequences, may contain an ncRNA. We also unveil one potential function of this ncRNA whose expression is regulated by alternative splicing decisions.
