lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

9.9K
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...

Nursing Code of Ethics01:29

Nursing Code of Ethics

4.5K
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,...

What is Gene Expression?

196.5K
Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

Chromatin Position Affects Gene Expression02:35

Chromatin Position Affects Gene Expression

24.8K
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences  access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area. 
Topologically Associated Domains (TADs)
The 3-dimensional positioning of chromatin in the nucleus influences the...

RNA Splicing01:32

RNA Splicing

60.6K
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...

Summary
This summary is machine-generated.

This study maps the long noncoding RNA (lncRNA) landscape during rotavirus (RV) infection, revealing significant changes in gene expression that activate innate immunity and suppress metabolism. Novel lncRNAs are identified as key regulators of the host antiviral response.

Area of Science:

  • Virology
  • Molecular Biology
  • Genomics

Background:

  • Rotavirus (RV) causes severe gastroenteritis in children.
  • The role of long noncoding RNAs (lncRNAs) in the host response to RV is poorly understood.

Purpose of the Study:

  • To comprehensively map the lncRNA and mRNA expression profiles in RV-infected cells.
  • To identify novel lncRNAs involved in the host's antiviral defense against RV.

Main Methods:

  • Integrated transcriptomic analysis of mRNA and lncRNA in RV-infected MA104 cells.
  • Deep sequencing and quantitative real-time PCR (qRT-PCR) for expression profiling.
  • Functional enrichment analysis and target prediction for lncRNAs.

Main Results:

  • Identification of 11,919 high-confidence lncRNAs, with 3651 mRNAs and 4655 lncRNAs differentially expressed.
  • Upregulation of innate immunity pathways (RIG-I-like receptor, Toll-like receptor, TNF signaling) and suppression of metabolic pathways.
  • Discovery of two novel lncRNAs (lncRNA-6479, lncRNA-4290) and immune-related mRNAs (OASL, C3) upregulated during RV infection.

Conclusions:

  • lncRNAs play a crucial role in coordinating host antiviral defense against rotavirus, primarily through transregulation.
  • This study provides a valuable genome-wide resource for investigating host-RV interactions and identifying therapeutic targets.
