m6A Regulator-Mediated Methylation Modification Patterns and Characteristics in COVID-19 Patients
Frontiers in Public Health
|June 3, 2022
Summary
RNA N6-methyladenosine (m6A) regulators are linked to COVID-19 severity. Identifying m6A subtypes in patients may lead to new treatment strategies for coronavirus disease 2019.
Area of Science:
- Molecular Biology
- Immunology
- Genomics
Background:
- RNA N6-methyladenosine (m6A) regulators play crucial roles in physiological functions and viral infections.
- The specific involvement of m6A regulators in coronavirus disease 2019 (COVID-19) pathogenesis is not well understood.
Purpose of the Study:
- To investigate the role of m6A regulators in COVID-19.
- To identify potential biomarkers for COVID-19 prediction and prognosis.
- To explore m6A-based subtypes in COVID-19 patients.
Main Methods:
- Bioinformatic analysis of gene expression profiles from COVID-19 patients (GSE157103).
- Differential gene expression analysis, random forest modeling, and nomogram construction for prediction.
- Consensus clustering to define m6A subtypes and assess immune associations.
Main Results:
- m6A modification levels were significantly higher in COVID-19 patients compared to non-COVID-19 individuals.
- Eight key m6A regulators were identified as optimal predictors for COVID-19.
- Two distinct m6A subtypes were identified; subtype A showed activated T-cell functions and suggested a better prognosis.
Conclusions:
- m6A regulators are potentially involved in the prevalence and progression of COVID-19.
- The identified m6A subtypes offer a promising avenue for developing targeted COVID-19 treatments.

02:23Master Transcription Regulators
7.1K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

02:32Histone Modification
14.2K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.

02:25Spreading of Chromatin Modifications
8.5K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

01:17Phase II Reactions: Methylation Reactions
375
Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...

02:04Covalently Linked Protein Regulators
7.5K
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.
