Insights

Metabolites can covalently modify proteins through novel lysine acylations, impacting gene expression and cell signaling. These modifications offer potential for cancer diagnosis and therapy.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cancer Research

Background:

  • Metabolites are key intermediates in cellular metabolism.
  • Metabolic reprogramming is a hallmark of cancer cells, leading to abnormal metabolite accumulation.
  • Metabolites can noncovalently interact with proteins to regulate cellular processes.

Purpose of the Study:

  • To review novel lysine acylations beyond acetylation.
  • To explore the characteristics and functions of nine specific lysine acylations.
  • To highlight the role of these modifications in tumorigenesis and their diagnostic/therapeutic potential.

Main Methods:

  • Review of existing literature on metabolite-protein interactions.
  • Focus on mass spectrometry-based identification of lysine acylations.
  • Classification of acylation types into histone and nonhistone modifications.

Main Results:

  • Metabolites covalently modify proteins via various lysine acylations (e.g., crotonylation, lactylation, succinylation).
  • These modifications regulate gene expression and intracellular signaling pathways.
  • Nine novel lysine acylations (excluding acetylation) are discussed, categorized as histone or nonhistone.

Conclusions:

  • Novel lysine acylations play significant roles in cellular functions and cancer development.
  • These acylation patterns serve as potential biomarkers for tumor diagnosis, monitoring, and therapeutic targets.

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.

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...

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Mutagenicity and Carcinogenicity01:25

Mutagenicity and Carcinogenicity

Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
