Summary
Researchers can now explore epigenetic patterns in cancer using MENT, a novel database integrating DNA methylation and gene expression data from normal and tumor tissues. This resource aids in understanding carcinogenesis by providing comprehensive, searchable data.
Area of Science:
- Epigenetics
- Cancer Biology
- Bioinformatics
Background:
- Epigenetic alterations, particularly DNA methylation, play a crucial role in cancer development.
- Understanding the interplay between DNA methylation and gene expression is vital for elucidating carcinogenesis.
- Existing resources often lack integrated analysis of both DNA methylation and gene expression across diverse cancer types.
Purpose of the Study:
- To develop and present MENT (Methylation and Expression database of Normal and Tumor tissues), a comprehensive integrated database.
- To provide researchers with a user-friendly platform for accessing and analyzing DNA methylation and gene expression data in various cancers.
- To facilitate the discovery of novel epigenetic biomarkers and therapeutic targets in oncology.
Main Methods:
- Integrated data from Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA).
- Combined DNA methylation and gene expression profiles from normal and tumor tissues.
- Developed a database with a user-friendly interface for 'gene search' and 'dataset search' functionalities.
- Incorporated filtering options for differential methylation analysis (direction, DM value, p-value).
Main Results:
- MENT is the first database offering integrated DNA methylation and gene expression data for diverse normal and tumor tissues.
- The database provides correlated DNA methylation and gene expression data in paired samples.
- User-friendly search functions allow efficient retrieval of differential methylation patterns based on genes or datasets.
- Clinicopathological information is integrated to contextualize epigenetic findings.
Conclusions:
- MENT serves as a valuable, freely accessible resource for cancer epigenetics research.
- The integrated approach in MENT enhances the understanding of epigenetic mechanisms in carcinogenesis.
- Facilitates easier identification of differentially methylated genes and their expression patterns in various cancer conditions.

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.

Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
