Insights

Cellular metabolism significantly influences epigenetic modifications, impacting gene expression and cell functions. Metabolic reprogramming in cancer alters epigenetic landscapes, offering potential therapeutic targets.

Area of Science:

  • Cellular biology
  • Epigenetics
  • Cancer metabolism

Background:

  • Cellular metabolism and epigenetic modifications are intricately linked, affecting chromatin structure and gene expression.
  • Nutrient availability influences epigenetic maintenance, crucial for homeostasis, growth, and differentiation.
  • Cancer cells exhibit metabolic reprogramming and epigenetic alterations that drive tumor development.

Purpose of the Study:

  • To review the role of metabolic reprogramming in regulating epigenetic modifications in cancer.
  • To highlight key metabolites involved in cancer-related epigenetic changes.
  • To explore the potential of targeting metabolic-epigenetic crosstalk for cancer therapy.

Main Methods:

  • Literature review summarizing current evidence on metabolic reprogramming and epigenetics in cancer.
  • Focus on key metabolites and their impact on epigenetic modifications.
  • Analysis of oncogenic signaling-driven metabolic changes.

Main Results:

  • Metabolic reprogramming alters epigenetic modifications through key metabolite levels (SAM, acetyl-CoA, α-KG, 2-HG, UDP-GlcNAc, lactate).
  • These metabolites dynamically regulate the epigenetic landscape in cancer cells.
  • Changes in metabolite abundance are driven by oncogenic signaling.

Conclusions:

  • Metabolic reprogramming is a critical factor in cancer development and progression.
  • Understanding the interplay between metabolism and epigenetics can reveal cancer mechanisms.
  • Targeting metabolic-epigenetic interactions presents a promising avenue for novel cancer therapies.

Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

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,...

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Metastasis02:30

Metastasis

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...

The Tumor Microenvironment02:17

The Tumor Microenvironment

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...
