lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

9.8K
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

18.5K
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

7.6K
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

4.3K
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:

  • Reproductive biology
  • Molecular biology
  • Genetics

Background:

  • Epididymal physiology research has significantly advanced over three decades.
  • Key discoveries include diverse small non-protein-coding RNAs (sRNAs) in the epididymis.

Purpose of the Study:

  • To review literature on the epididymal sRNA landscape.
  • To demonstrate the role of sRNAs in epididymal physiology and sperm maturation.

Main Methods:

  • High-throughput sequencing strategies.
  • Profiling of small non-protein-coding RNA (sRNA) expression in the mammalian epididymis.

Main Results:

  • Diverse classes of sRNAs, including microRNAs (miRNAs), are expressed along the epididymis.
  • Epithelial sRNAs accumulate in epididymosomes and spermatozoa, suggesting intercellular communication.
  • sRNAs fine-tune gene expression and contribute to sperm epigenome modification.

Conclusions:

  • sRNAs are vital for sperm transport, maturation, and storage in the epididymis.
  • Research on sRNAs offers potential for understanding male infertility and developing therapies.
