RNA-seq

9.1K
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases. 
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Background:

  • DNA methylation is a key epigenetic mechanism regulating gene expression.
  • Understanding genome-wide DNA methylation patterns is crucial for deciphering gene regulation and disease progression.
  • Methylated DNA immunoprecipitation (MeDIP) is a technique for enriching methylated DNA fragments.

Purpose of the Study:

  • To describe a protocol for applying MeDIP to DNA microarray hybridization.
  • To enable genome-wide DNA methylation analysis (DNA methylomics).
  • To facilitate the study of DNA methylation patterns and their correlation with biological events.

Main Methods:

  • Utilizes Methylated DNA Immunoprecipitation (MeDIP) with a specific antibody to enrich methylated DNA.
  • Combines MeDIP with tiling arrays (MeDIP-on-Chip) for genome-wide profiling.
  • Details the protocol for DNA microarray hybridization and subsequent data analysis.

Main Results:

  • Successfully applies MeDIP for genome-wide DNA methylation analysis.
  • Enables the investigation of DNA methylation patterns across the entire genome.
  • Provides a foundation for correlating methylation changes with biological phenomena.

Conclusions:

  • MeDIP-on-Chip is an effective method for genome-wide DNA methylation analysis.
  • This protocol facilitates comprehensive studies of DNA methylomics.
  • Enhanced understanding of DNA methylation can advance research in gene regulation and disease.
