Summary
Mitochondria are crucial for cell function and apoptosis. In cancer, their metabolic pathways may drive metastasis, possibly through evolution, alongside anoikis resistance.
Area of Science:
- Cellular biology
- Mitochondrial function
- Cancer biology
Background:
- Mitochondria are vital for ATP generation, redox buffering, and apoptosis.
- Traditionally viewed as dysfunctional in cancer, mitochondria now appear integral to metastasis.
Purpose of the Study:
- To review mitochondrial metabolic pathways.
- To explore their role in the malignant phenotype and metastasis.
- To propose an evolutionary hypothesis for cancer progression.
Main Methods:
- Review of classical mitochondrial metabolic events.
- Analysis of the link between mitochondrial metabolism and malignant phenotype.
- Consideration of evolutionary processes in cancer development.
Main Results:
- Mitochondrial metabolic pathways are essential for the malignant phenotype.
- Oxidative metabolism in tumor cells supports metastasis.
- Inactivation of anoikis is linked to mitochondrial function in metastasis.
Conclusions:
- Mitochondrial metabolism plays a critical role in cancer metastasis.
- The evolution of cancer may involve co-option of mitochondrial pathways and anoikis resistance.

02:30Metastasis
5.4K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

01:37Mitochondria
13.4K
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,...

02:53Adaptive Mechanisms in Cancer Cells
5.7K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.

01:19Translocation of Proteins into the Mitochondria
8.8K
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,...

02:17The Tumor Microenvironment
6.3K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

02:59Animal Mitochondrial Genetics
7.8K
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...
