Insights

Melanoma cells adapt to therapies through non-genetic changes in metabolism, hindering treatment. Understanding this metabolic plasticity is key to overcoming therapy resistance and preventing melanoma relapse.

Area of Science:

  • Oncology
  • Cancer Biology
  • Metabolic Research

Background:

  • Therapy resistance remains a significant obstacle in achieving curative treatments for melanoma.
  • Non-genetic adaptive mechanisms, including metabolic reprogramming, play a crucial role in melanoma therapy resistance and relapse.

Purpose of the Study:

  • To explore the role of melanoma's inherent metabolic plasticity in disease progression and therapy resistance.
  • To detail metabolic alterations during targeted therapy response phases (early response, drug tolerance, acquired resistance).
  • To discuss the influence of non-genetic programs like transcription and translation on these adaptive processes.

Main Methods:

  • Review of current clinical and experimental findings on melanoma metabolism.
  • Analysis of metabolic changes during different stages of targeted therapy response.
  • Examination of non-genetic regulatory mechanisms (transcription, translation) in therapy resistance.

Main Results:

  • Melanoma cells exhibit significant metabolic plasticity, altering their metabolism reversibly during metastasis and in response to anti-cancer therapies.
  • Metabolic reprogramming is a key driver of both melanoma progression and the development of resistance to targeted therapies.
  • Non-genetic adaptive mechanisms, controlled by transcriptional and translational programs, are prevalent and diverse.

Conclusions:

  • Melanoma's metabolic plasticity is a critical factor enabling disease progression and the acquisition of therapy resistance.
  • Innovative strategies are needed to monitor and counteract these adaptive, non-genetic resistance mechanisms to improve melanoma treatment outcomes.

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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

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...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
