Insights

Transcription factors (TFs) drive cancer by altering gene expression. Targeting their post-translational modifications (PTMs) offers new therapeutic strategies for

Area of Science:

  • Oncology and Molecular Biology: Focuses on the role of transcription factors and their modifications in cancer development and treatment.

Background:

  • Dysregulated transcription factors (TFs) are key drivers of cancer, promoting uncontrolled cell growth, migration, and immune evasion.
  • Most TFs are considered 'undruggable' due to challenges in directly modulating their activity.
  • Post-translational modifications (PTMs) critically regulate TF functions, presenting alternative therapeutic targets.

Purpose of the Study:

  • To systematically review emerging concepts and agents targeting PTMs of TFs in cancer.
  • To explore the potential of PTM-associated TF targeting as a novel paradigm for cancer therapy.

Main Methods:

  • Comprehensive literature review of PTMs affecting TF activity and their role in cancer.
  • Analysis of current and emerging therapeutic strategies targeting TF PTMs.
  • Synthesis of findings to highlight potential treatment paradigms.

Main Results:

  • PTMs significantly influence TF localization, interactions, and stability, thereby controlling gene expression networks in cancer.
  • Targeting specific TF PTMs offers a promising strategy to overcome the 'undruggable' nature of many TFs.
  • Emerging agents demonstrate potential in modulating PTMs for therapeutic benefit.

Conclusions:

  • PTM-associated TF targeting represents a promising frontier in cancer therapy.
  • Further research into PTMs could unlock new treatments for various cancers.
  • This review provides a framework for developing novel TF-targeted cancer therapies.

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...

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...

Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

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.

Transcription Factors02:16

Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...
