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 RNAs02:30

siRNA - Small Interfering RNAs

18.7K
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...

Encoding01:19

Encoding

873
Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the environment, the brain labels or codes it. The information is then organized with similar information and connected to existing concepts. Encoding occurs through automatic processing and effortful processing.
Automatic processing involves the encoding of details like time, space, frequency, and the meaning of words, usually done without conscious...

Nursing Code of Ethics01:29

Nursing Code of Ethics

4.6K
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:

  • Genomics
  • Molecular Biology
  • Biochemistry

Background:

  • Non-coding RNAs (ncRNAs) are universally expressed and a major feature of genomes.
  • Many transcribed genomic regions lack protein-coding annotation but contain small open reading frames (smORFs).
  • Historically, ncRNAs were considered untranslated, but emerging evidence challenges this view.

Purpose of the Study:

  • To critically review the coding capacity of ncRNAs.
  • To discuss the knowns and unknowns in this emerging field.
  • To explore the biological and pathological relevance of ncRNA-derived products.

Main Methods:

  • Literature review and critical analysis of existing studies.
  • Discussion of potential coding mechanisms for ncRNAs.
  • Exploration of the roles of ncRNA-derived peptides/proteins.

Main Results:

  • Increasing evidence supports translational events from ncRNAs previously thought to lack coding potential.
  • Products from these novel translational events exhibit significant regulatory functions in biological and pathological processes.
  • ncRNA-derived peptides/proteins have potential roles in disease development.

Conclusions:

  • ncRNAs possess a previously underestimated coding capacity.
  • Understanding ncRNA translation opens new avenues for disease diagnosis and therapy.
  • Further research into ncRNA-derived peptides/proteins is crucial for theranostic applications.
