Eukaryotic Compartmentalization01:46

Eukaryotic Compartmentalization

156.8K
One of the distinguishing features of eukaryotic cells is that they contain membrane-bound organelles, such as the nucleus and mitochondria, that carry out specialized functions. Since biological membranes are only selectively permeable to solutes, they help create a compartment with controlled conditions inside an organelle. These microenvironments are tailored to the organelle's specific functions and help isolate them from the surrounding cytosol.
For example, lysosomes in the animal cells...

Subcellular Fractionation01:32

Subcellular Fractionation

7.1K
The homogenate obtained after cell lysis contains various membrane-bound organelles that can be further separated into pure fractions by subcellular fractionation. These isolates are used to study specific cellular components, analyze localized protein activity, and are even employed in diagnostics. Fractionation is typically achieved using centrifugation methods, the most common being density-gradient and differential centrifugation.

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

12.6K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Genomic DNA in Eukaryotes

47.1K
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.

Genomic DNA in Prokaryotes00:46

Genomic DNA in Prokaryotes

44.1K
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

Area of Science:

  • Genomics
  • Computational Biology
  • Cell Biology

Background:

  • Single-cell Hi-C (scHi-C) technologies allow investigation of 3D genome organization variability at the single-cell level.
  • Existing computational methods analyze features like A/B compartments and chromatin loops but lack single-cell subcompartment annotation.
  • Subcompartments offer a refined view of large-scale chromosome spatial organization crucial for understanding cellular function.

Approach:

  • Introduced scGhost, a novel computational method for single-cell subcompartment annotation.
  • scGhost utilizes graph embedding and constrained random walk sampling for robust analysis.
  • Validated scGhost on both scHi-C and 3D genome imaging data.

Key Points:

  • scGhost reliably identifies single-cell subcompartments, revealing cell-to-cell variability in nuclear organization.
  • Application to human prefrontal cortex data identified cell type-specific subcompartments.
  • These subcompartments show strong correlations with cell type-specific gene expression patterns.

Conclusions:

  • scGhost provides an effective new tool for annotating single-cell 3D genome subcompartments from scHi-C data.
  • The method offers insights into the functional implications of subcompartment organization at the single-cell level.
  • scGhost is applicable to diverse biological contexts for studying genome organization.
