Insights

Mitochondrial Rho GTPases (MIROs) are crucial for neuron function but also significantly impact cancer progression. These proteins promote tumor growth, invasion, and metastasis across various cancer types, suggesting potential therapeutic targets.

Area of Science:

  • Mitochondrial biology
  • Cancer research
  • Cellular signaling

Background:

  • Mitochondrial Rho GTPases (MIRO1 and MIRO2) are known for their role in mitochondrial trafficking in neurons.
  • Emerging evidence highlights critical, yet understudied, roles of MIROs in cancer development and progression.

Purpose of the Study:

  • To review the expression patterns of MIROs in tumors.
  • To elucidate the molecular mechanisms by which MIROs influence cancer cell growth, invasion, and metastasis.
  • To examine the role of MIROs in non-cancerous cells within the tumor microenvironment.

Main Methods:

  • Literature review of studies on MIROs in cancer.
  • Analysis of MIRO expression data in various tumor types.
  • Examination of molecular pathways linking MIROs to cancer hallmarks.

Main Results:

  • MIROs are frequently dysregulated in tumors.
  • MIROs primarily promote tumor progression, including cell growth, invasion, and metastasis.
  • MIROs in the tumor microenvironment can influence tumor development.

Conclusions:

  • MIROs are key drivers of tumor progression in diverse cancers.
  • MIROs represent promising novel therapeutic targets for cancer treatment.
  • Targeting mitochondrial proteins is a viable clinical strategy.

Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:

Cell Polarization by Rho Proteins01:21

Cell Polarization by Rho Proteins

Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...

The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

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...

Destabilization of Microtubules01:45

Destabilization of Microtubules

The destabilization of microtubules can occur during different stages of the microtubule lifecycle, such as nucleation or elongation. It can take place at either end of the microtubule or in the microtubule lattices as a whole. The lifespan of individual microtubules within a cell varies according to the cell type and stage of the cell cycle. During interphase, the lifespan of the microtubule is about 30 minutes, while during cell division, it is about 15 minutes. In axonal microtubules of...

Electron Transport Chain: Complex I and II01:46

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...
