lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

10.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

siRNA - Small Interfering RNAs

18.8K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

piRNA - Piwi-interacting RNAs

7.7K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

Nursing Code of Ethics01:29

Nursing Code of Ethics

4.8K
The Nursing Code of Ethics sets the ethical benchmark for the profession, and guides nurses in ethical analysis and decision making at the societal, organizational, and clinical levels. The code encompasses showing compassion and respect for the patient, their families, and communities in all circumstances while committing to providing patient-centered care. In addition, the code states that nurses must advocate for the patient by defending a cause or recommendation to protect their rights,...

Area of Science:

  • Molecular Biology
  • Neuroscience
  • Genetics

Background:

  • Stroke is a major global cause of death and disability.
  • Understanding stroke's cellular and molecular mechanisms is crucial.
  • Long non-coding RNAs (lncRNAs) are increasingly recognized for their roles in disease pathogenesis.

Purpose of the Study:

  • To identify and characterize aberrantly expressed lncRNAs in ischemic stroke.
  • To explore the potential functions and mechanisms of these lncRNAs in stroke.
  • To investigate lncRNAs as potential biomarkers and therapeutic targets for stroke.

Main Methods:

  • RNA sequencing, deep sequencing, and microarrays were used to screen lncRNAs.
  • In vitro studies utilized oxygen-glucose deprivation (OGD) cell models.
  • Gene Ontology (GO) enrichment analysis was performed to predict lncRNA functions.

Main Results:

  • Nine specific lncRNAs (ANRIL, MALAT1, N1LR, MEG3, H19, C2dat1, FosDT, SNHG14, TUG1) were found to be upregulated in ischemic stroke models.
  • These lncRNAs are implicated in promoting apoptosis, angiogenesis, and inflammation.
  • GO analysis suggested MEG3, H19, and MALAT1 are involved in neurogenesis, angiogenesis, and inflammation via gene regulation.

Conclusions:

  • Aberrantly expressed lncRNAs play significant roles in the pathophysiology of ischemic stroke.
  • Specific lncRNAs like MEG3, H19, and MALAT1 are promising candidates for further investigation.
  • Elucidating lncRNA functions may lead to novel diagnostic biomarkers and therapeutic strategies for stroke.
