Summary
Mitochondria, crucial for cell functions, change shape in response to cues. Deregulated mitochondrial dynamics are linked to cancer, with oncogenes altering morphology and promoting tumor growth.
Area of Science:
- Cell Biology
- Cancer Biology
- Mitochondrial Biology
Background:
- Mitochondria are dynamic organelles vital for cellular bioenergetics and apoptosis.
- Mitochondrial network morphology influences physiological processes.
- Dysregulation of mitochondria is observed in various cancers.
Purpose of the Study:
- To review how mutated oncogenes and effector pathways regulate mitochondrial dynamics.
- To explore the impact of altered mitochondrial morphology on tumorigenic growth.
Main Methods:
- Literature review of studies on mitochondrial dynamics in cancer.
- Analysis of oncogene-driven alterations in mitochondrial morphology.
- Examination of the physiological consequences for tumor growth.
Main Results:
- Commonly mutated oncogenes and their pathways significantly impact mitochondrial dynamics.
- Altered mitochondrial morphology is a hallmark of cancer.
- Changes in mitochondrial shape are linked to tumorigenic processes.
Conclusions:
- Mitochondrial dynamics are a critical target in cancer.
- Understanding these pathways can reveal new therapeutic strategies for cancer treatment.

01:45Mitochondrial Membranes
17.5K
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,...

01:19Interactions Between Signaling Pathways
7.5K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

03:03mTOR Signaling and Cancer Progression
4.9K
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.

01:46Electron Transport Chain: Complex I and II
19.3K
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.

01:19Translocation of Proteins into the Mitochondria
13.6K
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,...

01:22PI3K/mTOR/AKT Signaling Pathway
5.9K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...
