Summary
Methylation, a key protein modification, is read by specific readers to control protein function and impact diseases like cancer. Understanding these readers and their crosstalk with other modifications offers new therapeutic avenues.
Area of Science:
- Biochemistry
- Epigenetics
- Molecular Biology
Background:
- Methylation is a crucial post-translational modification (PTM) impacting protein function.
- Methylation occurs on lysine or arginine residues in histone and nonhistone proteins.
- Methylated residues are recognized by specific protein domains known as methyl readers.
Purpose of the Study:
- To summarize current knowledge on protein function regulation by methyl readers.
- To highlight the role of methyl readers in various diseases, including cancer.
- To propose future research directions focusing on methylation and other PTM crosstalk.
Main Methods:
- Review of existing literature on methylation and methyl readers.
- Analysis of the mechanisms by which methyl readers recognize methylated proteins.
- Discussion of the implications of methyl reader activity in disease pathogenesis.
Main Results:
- Methyl readers (e.g., chromodomain, MBT, Tudor) recognize methylated residues via induced-fit mechanisms.
- Methylation-dependent activities regulate protein function, influencing protein degradation and stabilization.
- Histone methylation differs from nonhistone methylation in degree (di-/tri-methylation vs. mono-methylation).
Conclusions:
- Methyl readers play a significant role in regulating protein function and are implicated in disease progression, particularly cancer.
- Targeting methyl readers and their interactions presents potential therapeutic strategies for cancer.
- Further research into the crosstalk between methylation and other PTMs mediated by methyl readers is essential for advancing cancer therapeutics.

6.1K
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,...

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.

8.9K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

8.5K
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.

5.6K
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...
