Ribosome Profiling02:24

Ribosome Profiling

3.6K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Gross Anatomy of the Liver01:17

Gross Anatomy of the Liver

770
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...

Area of Science:

  • Human liver anatomy
  • Transcriptional analysis
  • Spatial biology

Background:

  • Understanding the cellular origins of liver disease requires detailed knowledge of liver spatial-cellular anatomy.
  • Liver zonation, the spatial organization of hepatocytes, plays a crucial role in liver function and disease pathogenesis.

Purpose of the Study:

  • To provide a detailed transcriptional map of human liver zonation.
  • To establish a reference dataset for spatial heterogeneity studies in the liver.

Main Methods:

  • Spatial transcriptomics was performed on normal human liver tissue sections.
  • High-quality data from 6581 spots from two human donors were analyzed.
  • Hepatocytes were classified into four distinct sub-groups based on transcriptional profiles.

Main Results:

  • Detailed information on liver zonation at the transcriptional level was obtained.
  • Four distinct hepatocyte sub-groups were identified, reflecting spatial heterogeneity.
  • A high-quality dataset of spatial transcriptomic data from normal human liver was generated.

Conclusions:

  • The generated dataset serves as a reliable reference for studying spatial heterogeneity in liver lobules.
  • This work enhances our understanding of the transcriptional landscape of the human liver.
  • The findings are critical for future research into the cellular basis of liver diseases.
