Mitochondria are the power plants of the cell. (acsh.org)
A recent paper by researchers at Newcastle University, which appeared in the EMBO journal, reported, for the first time, that there is now proof that mitochondria are essential for cell aging. (acsh.org)
Mitochondria are sub-cellular structures, called organelles, which are found in almost all human cells. (acsh.org)
The respiratory chain (RC) is the area of the mitochondria where the chemical energy for cells (ATP) is generated, and decreasing the RC function is associated with aging. (acsh.org)
By inducing autophagy, the research team effectively eliminated all the mitochondria from within the cells they studied. (acsh.org)
They subsequently observed that the population of older cells displayed more youthful characteristics once their mitochondria was gone such as reduced levels of inflammatory molecules, oxygen-free radicals and expression of age-related genes all the conditions observed in younger cells. (acsh.org)
We already had some clues that mitochondria played a role in the ageing of cells, but scientists around the world have struggled to understand exactly how and to what extent these were involved. (acsh.org)
Continuing, Dr. Joao said, These new findings highlight that mitochondria are actually essential to the ageing of cells. (acsh.org)
Prior to this study , it was recognized that mitochondria were involved with regulation of lifespan, however, when damage had occurred to the mitochondria, it increased the lifespan of the cells. (acsh.org)
The results of this study will hopefully provide future therapeutic value to counteract the ageing of cells utilizing mitochondria as a target. (acsh.org)
In these cells, mitochondria are labeled with a red fluorescent dye, and the platinum compound targeted to the mitochondria is labeled green. (scitechdaily.com)
By targeting mitochondria with the anticancer drug cisplatin, chemists have developed a new way to kill cancer cells that have shown resistance to cisplatin. (scitechdaily.com)
The researchers found that when cisplatin was delivered to cellular structures called mitochondria. (scitechdaily.com)
To help figure that out, the researchers created a form of cisplatin targeted to go to mitochondria - cell organelles that generate energy. (scitechdaily.com)
Because mitochondria are involved in apoptosis, the researchers wanted to see whether they could induce cell death by targeting mitochondrial DNA, particularly in cells that are already resistant to regular cisplatin. (scitechdaily.com)
To do that, they developed a new way to tag the drug with a protein fragment developed in Kelley's lab that can enter the cell and accumulate in mitochondria. (scitechdaily.com)
However, by targeting the platinum-based drug to mitochondria, at a given dose, the researchers showed they could kill equal numbers of resistant and nonresistant cells. (scitechdaily.com)

Mitochondria are the living machines within cells that act as their "power plants," converting the energy-rich nutrients in our food into ATP, the form of energy that directly powers biochemical reactions in the cell. (sens.org)
Unlike any other part of the cell, mitochondria have their own mitochondrial DNA (mtDNA), which encodes 13 of the thousands of protein subunits of the ETS. (sens.org)
But just like real power plants, mitochondria generate toxic waste products in the process of "burning" food energy as fuel - in this case, spewing out highly-reactive molecules called free radicals, which can damage cellular structures. (sens.org)
Our cells have a system in place ( mitophagy ) for removing defective mitochondria, following which the remaining mitochondria are replicated to make up for lost numbers, so you wouldn't think this would be a problem. (sens.org)
This has the perverse result that the cell tends to hang onto these defective, mutant mitochondria , while sending others with much more common but milder defects to the cellular recycling center. (sens.org)
Mitochondria with deletion mutations thus have a selective advantage over healthy or mildly damaged mitochondria, with the result that once even one mitochondrion suffers a deletion, its progeny quickly take over the entire cell. (sens.org)

Mitochondria are involved not only in energy production, but also in several other critical cellular functions, including cell division and cell-preserving responses to various types of stress. (scripps.edu)
But the scientific tools for studying the fine details of mitochondria structure have been limited. (scripps.edu)
Mitochondria are one of the many membrane-bound molecular machines, or "organelles," that dwell within the cells of plants and animals. (scripps.edu)
Typically numbering in the hundreds to thousands per cell, mitochondria have their own small genomes, and have a distinctive structure with an outer membrane and a wavy inner membrane where key biochemical reactions occur. (scripps.edu)
The researchers' "surface morphometrics toolkit," as they call it, enables the detailed mapping and measurement of the structural elements of individual mitochondria. (scripps.edu)
The team demonstrated the toolkit by using it to map structural details on mitochondria when their cells are subjected to endoplasmic reticulum stress-a type of cell stress that is seen often in neurodegenerative diseases. (scripps.edu)
With their successful, proof-of-principle demonstrations of the new toolkit, the Grotjahn lab will now use it for studying in more detail how mitochondria respond to cellular stresses or other changes induced by diseases, toxins, infections and even pharmaceuticals. (scripps.edu)

Some have flagella, or hairlike structures that help them move. (studylib.net)

A number of direct and indirect radiation interaction pathways can produce damage to the DNA of irradiated cells. (cdc.gov)
They interact with each other and their environment through a variety of pathways, including cell-surface receptors, ligands, and signal transduction cascades. (ashdin.com)
They actively participate in cellular signaling pathways, communicating with other cellular components through various mechanisms. (nature.com)
