Mitochondria

Mitochondria

Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Animal Mitochondrial Genetics

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Mutations

Mutations

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
Chromosomal Alterations Are Large-Scale Mutations
While point mutations are changes in a single nucleotide in...

Electron Transport Chain: Complex I and II

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Mitochondrial Membranes

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

Background:

Single-cell gene expression analysis is crucial for understanding cellular heterogeneity and regulatory networks.
Existing methods for isolating and processing individual cells for deep sequencing are limited in throughput and efficiency.

Purpose of the Study:

To develop a high-throughput droplet-microfluidic method for barcoding RNA from thousands of individual cells.
To enable quantitative, in-depth sequencing of single-cell RNA for biological discovery.

Main Methods:

A droplet-microfluidic system was engineered for high-throughput isolation and RNA barcoding of individual cells.
Next-generation sequencing was employed for quantitative analysis of barcoded single-cell RNA.
Mouse embryonic stem cells were analyzed to demonstrate the method's utility.

Main Results:

The developed method achieves single-cell resolution with a low noise profile.
Analysis of mouse embryonic stem cells revealed detailed population structure and heterogeneous differentiation onset upon leukemia inhibitory factor (LIF) withdrawal.
High reproducibility of the single-cell data facilitated deconstruction of cell populations and inference of gene expression relationships.

Conclusions:

The droplet-microfluidic approach provides an effective and scalable solution for single-cell RNA sequencing.
This method advances the ability to study cellular heterogeneity, developmental processes, and gene regulatory networks at the single-cell level.
