  2. DNA methylation - Wikipedia

    en.wikipedia.org/wiki/DNA_methylation

    DNA methylation appears absolutely required in differentiated cells, as knockout of any of the three competent DNA methyltransferase results in embryonic or post-partum lethality. By contrast, DNA methylation is dispensable in undifferentiated cell types, such as the inner cell mass of the blastocyst, primordial germ cells or embryonic stem cells.

  3. Bayesian tool for methylation analysis - Wikipedia

    en.wikipedia.org/wiki/Bayesian_tool_for...

    Bayesian tool for methylation analysis, also known as BATMAN, is a statistical tool for analysing methylated DNA immunoprecipitation (MeDIP) profiles. It can be applied to large datasets generated using either oligonucleotide arrays (MeDIP-chip) or next-generation sequencing (MeDIP-seq), providing a quantitative estimation of absolute methylation state in a region of interest.

  4. Illumina Methylation Assay - Wikipedia

    en.wikipedia.org/wiki/Illumina_Methylation_Assay

    The Illumina Methylation Assay using the Infinium I platform uses 'BeadChip' technology [clarification needed] to generate a comprehensive genome-wide profiling of human DNA methylation. Similar to bisulfite sequencing and pyrosequencing , this method quantifies methylation levels at various loci within the genome .

  5. Bisulfite sequencing - Wikipedia

    en.wikipedia.org/wiki/Bisulfite_sequencing

    All subsequent DNA methylation analysis techniques using bisulfite-treated DNA is based on this report by Frommer et al. (Figure 2). [6] Although most other modalities are not true sequencing-based techniques, the term "bisulfite sequencing" is often used to describe bisulfite-conversion DNA methylation analysis techniques in general.

  6. Combined bisulfite restriction analysis - Wikipedia

    en.wikipedia.org/wiki/Combined_Bisulfite...

    The first few steps of COBRA, and the molecular changes caused by each step to methylated and unmethylated CpG sites. Combined Bisulfite Restriction Analysis (or COBRA) is a molecular biology technique that allows for the sensitive quantification of DNA methylation levels at a specific genomic locus on a DNA sequence in a small sample of genomic DNA. [1]

  7. Multiplex ligation-dependent probe amplification - Wikipedia

    en.wikipedia.org/wiki/Multiplex_ligation...

    MLPA has a variety of applications [5] including detection of mutations and single nucleotide polymorphisms, [6] analysis of DNA methylation, [7] relative mRNA quantification, [8] chromosomal characterisation of cell lines and tissue samples, [9] detection of gene copy number, [10] detection of duplications and deletions in human cancer ...

  8. Epigenetic clock - Wikipedia

    en.wikipedia.org/wiki/Epigenetic_clock

    An epigenetic clock is a biochemical test that can be used to measure age. The test is based on modifications that change over time and regulate how genes are expressed. Typically they can use DNA methylation levels, measuring the accumulation of methyl groups to one's DNA molecules, or more recently, based on the histone

  9. Epigenome editing - Wikipedia

    en.wikipedia.org/wiki/Epigenome_editing

    The ability to directly target and edit individual methylation sites is critical to determining the exact function of DNA methylation at a specific site. Epigenome editing is a powerful tool that allows this type of analysis.
