Summary
Cancer cells reprogram metabolism, often favoring aerobic glycolysis. This review explores other crucial metabolic pathways like oxidative phosphorylation and fatty acid oxidation in tumor development and survival.
Area of Science:
- Oncology
- Cancer Metabolism
- Biochemistry
Background:
- Metabolic alterations are a hallmark of cancer.
- Cancer cells frequently rewire metabolism, notably through aerobic glycolysis, to support proliferation.
- While aerobic glycolysis is well-studied, other metabolic pathways are also critical for tumor growth.
Purpose of the Study:
- To review the contribution of metabolic alterations beyond aerobic glycolysis to cancer development and survival.
- To analyze the molecular mechanisms regulating the balance between different metabolic pathways in cancer.
- To explore potential therapeutic strategies targeting cancer metabolism.
Main Methods:
- Literature review of studies on cancer metabolism.
- Analysis of molecular mechanisms driving metabolic reprogramming in tumors.
- Discussion of therapeutic approaches targeting metabolic pathways.
Main Results:
- Cancer cells utilize various metabolic pathways, including oxidative phosphorylation, gluconeogenesis, and fatty acid oxidation, which can be essential for tumor survival.
- These alternative metabolic pathways can be more critical than aerobic glycolysis in certain cancers.
- Dysregulation of these pathways contributes significantly to cancer progression.
Conclusions:
- Metabolic reprogramming in cancer involves more than just aerobic glycolysis.
- Understanding the interplay of various metabolic pathways is crucial for comprehending tumor development.
- Targeting these diverse metabolic processes offers promising avenues for cancer therapy.

02:53Adaptive Mechanisms in Cancer Cells
6.0K
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.

01:46Electron Transport Chain: Complex I and II
15.2K
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.

03:03mTOR Signaling and Cancer Progression
3.9K
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.

01:37Mitochondria
15.3K
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,...

02:21Cancers Originate from Somatic Mutations in a Single Cell
13.2K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

01:22PI3K/mTOR/AKT Signaling Pathway
4.1K
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...
