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...

Cell Specific Gene Expression

16.6K
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

B Cell Activation and Differentiation

16.9K
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

Area of Science:

  • Molecular Biology
  • Genetics
  • Cell Biology

Background:

  • Cell differentiation is a complex process requiring precise regulation.
  • Long noncoding RNAs (lncRNAs) are increasingly recognized for their regulatory roles in biological processes.

Purpose of the Study:

  • To investigate the involvement and profiles of lncRNAs during lineage-specific cell differentiation.
  • To identify specific lncRNAs that regulate myocyte differentiation.

Main Methods:

  • Comparative expression analysis of polyA-minus RNAs during myocyte and adipocyte differentiation.
  • Identification of novel lncRNAs and their clustering patterns (transcription open domains).
  • Loss-of-function screening in C2C12 cells to identify critical myogenic lncRNAs.

Main Results:

  • Thousands of novel lncRNAs were identified, with distinct profiles during differentiation.
  • lncRNAs are organized in co-regulated clusters, forming transcription open domains (TODs).
  • Knockdown of three identified myogenic lncRNAs impaired myocyte differentiation and signaling pathways.

Conclusions:

  • lncRNAs play active and crucial roles in lineage-specific cell differentiation.
  • A comprehensive signaling pathway involving both protein and lncRNA factors is beginning to be elucidated.
