Insights

Noncoding RNAs (ncRNAs) epigenetically regulate hepatic stellate cell (HSC) activation, a key driver of liver fibrosis. Understanding these ncRNA mechanisms offers new therapeutic targets for liver fibrosis and cirrhosis.

Area of Science:

  • Hepatology
  • Epigenetics
  • Molecular Biology

Background:

  • Liver fibrosis is a major cause of liver disease mortality globally.
  • Effective treatments for reversing liver fibrosis are limited.
  • Hepatic stellate cell (HSC) activation is central to liver fibrosis development.

Purpose of the Study:

  • To review the role of noncoding RNAs (ncRNAs) in HSC activation during liver fibrosis.
  • To explore the epigenetic mechanisms underlying ncRNA regulation in HSCs.
  • To highlight the potential of ncRNAs as therapeutic targets for liver fibrosis.

Main Methods:

  • Literature review focusing on ncRNAs, epigenetics, and HSC activation.
  • Analysis of gene expression and epigenetic modifications in HSCs.
  • Synthesis of current research on ncRNA functions in liver fibrosis pathogenesis.

Main Results:

  • ncRNAs are established regulators of HSC transdifferentiation into myofibroblasts.
  • Epigenetic modifications mediated by ncRNAs influence HSC activation.
  • ncRNA-mediated epigenetic changes offer insights into gene regulation in liver fibrosis.

Conclusions:

  • ncRNAs play a critical role in the epigenetic regulation of HSCs in liver fibrosis.
  • Understanding ncRNA-epigenetic interactions provides novel therapeutic strategies.
  • Targeting ncRNAs holds promise for treating liver fibrosis and cirrhosis.

Liver Regeneration01:24

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Cell Specific Gene Expression01:58

Cell Specific Gene Expression

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...

Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

RNA Stability01:53

RNA Stability

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

lncRNA - Long Non-coding RNAs

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...

Chromatin Structure Regulates pre-mRNA Processing02:41

Chromatin Structure Regulates pre-mRNA Processing

In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.
The chromatin structure, especially...
