Summary
Mitochondrial DNA alterations are common in breast cancer, potentially contributing to its development. This review summarizes these genomic changes and their functional impacts on cancer progression.
Area of Science:
- Cellular Biology
- Genetics
- Oncology
Background:
- Mitochondria are crucial for cellular energy, free radical production, and apoptosis.
- Mitochondrial DNA (mtDNA) mutations are implicated in carcinogenesis due to high susceptibility and poor repair.
- Breast cancer, a prevalent cancer, exhibits various mtDNA alterations alongside nuclear DNA changes.
Purpose of the Study:
- To review reported mitochondrial genomic alterations in breast cancer.
- To summarize the functional consequences of these mtDNA changes.
Main Methods:
- Literature review of studies reporting mitochondrial DNA alterations in breast cancer.
- Analysis of functional impacts associated with identified mtDNA mutations.
Main Results:
- Multiple types of mitochondrial genomic alterations have been identified in breast cancer tissues.
- These alterations can affect mitochondrial function, potentially influencing cancer cell behavior.
Conclusions:
- Mitochondrial DNA alterations represent a significant factor in breast cancer development and progression.
- Further research into mtDNA's role could offer new therapeutic strategies for breast cancer.

01:46Electron 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...

01:45Mitochondrial 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,...
01:37Mitochondria
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,...
02:59Animal 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...
01:19Translocation of Proteins into the Mitochondria
Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

02:55The Nucleolus
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
