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...

RNA Splicing01:32

RNA Splicing

60.7K
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

Ribosomal RNA Synthesis02:53

Ribosomal RNA Synthesis

14.9K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

Nursing Code of Ethics01:29

Nursing Code of Ethics

4.7K
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,...

Coronary Circulation01:21

Coronary Circulation

7.6K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Area of Science:

  • Biochemistry
  • Genomics
  • Obstetrics

Background:

  • Preeclampsia is a leading cause of maternal and perinatal mortality.
  • Clinical symptoms of preeclampsia manifest late, despite early origins.
  • Early detection is crucial for mitigating risks to mother and fetus.

Purpose of the Study:

  • To identify circulating small non-coding RNAs in first-trimester plasma that differentiate preeclampsia from healthy pregnancies.
  • To develop a predictive model for early preeclampsia diagnosis using these RNA transcripts.

Main Methods:

  • Small non-coding RNA sequencing was performed on plasma samples from 75 pregnant women (preeclampsia and control groups).
  • Differential expression analysis identified 25 key RNA transcripts.
  • A supervised classification pipeline using logistic regression and cross-validation was developed.

Main Results:

  • Twenty-five differentially expressed small non-coding RNA transcripts were identified between preeclampsia and control groups.
  • The developed classification pipeline achieved an average Area Under the Curve (AUC) of 0.86.
  • Circulating small non-coding RNAs show significant predictive value for preeclampsia in the first trimester.

Conclusions:

  • Circulating small non-coding RNAs in the first trimester hold predictive value for preeclampsia.
  • These findings support the development of a novel, non-invasive early diagnostic tool for preeclampsia.
  • Early diagnosis via RNA biomarkers can potentially reduce life-threatening risks associated with preeclampsia.
