Mitochondrial Membranes01:45

Mitochondrial Membranes

15.0K
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,...

Cancer Stem Cells and Tumor Maintenance

5.3K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Adaptive Mechanisms in Cancer Cells

6.2K
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.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

16.9K
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...

Mitochondria01:37

Mitochondria

17.7K
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,...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.1K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Area of Science:

  • Oncology
  • Cell Biology
  • Metabolic Research

Background:

  • Tumors exhibit heterogeneity, with cancer stem cells (CSCs) driving growth and relapse.
  • CSCs possess distinct metabolic profiles conferring resistance to chemotherapy.
  • Altered mitochondrial dynamics, including fusion, fission, and mitophagy, underpin CSC phenotypes.

Purpose of the Study:

  • To investigate the role of mitochondrial dynamics in cancer stem cell (CSC) metabolism and phenotypes.
  • To explore targeting mitochondrial dynamics as a therapeutic strategy against CSCs.

Main Methods:

  • Analysis of CSC metabolic signatures.
  • Investigation of mitochondrial fusion, fission, and mitophagy pathways in CSCs.
  • Evaluation of therapeutic targeting of mitochondrial dynamics.

Main Results:

  • CSCs exhibit unique metabolic signatures linked to mitochondrial function.
  • Mitochondrial dynamics (fusion/fission) and mitophagy regulate CSC phenotypes, including metabolism and reactive oxygen species (ROS) levels.
  • The protein machinery governing mitochondrial dynamics presents a potential therapeutic target.

Conclusions:

  • Mitochondrial dynamics are crucial for maintaining CSC properties and driving tumor progression.
  • Targeting mitochondrial dynamics could selectively eliminate CSCs, reducing metastasis and relapse risks.
  • This approach offers a promising new avenue for cancer therapy.
