Summary
This review explores how histone lysine methylation contributes to epigenetic memory, ensuring stable cell identity and gene expression patterns are maintained through cell division.
Area of Science:
- Developmental Biology
- Epigenetics
- Molecular Biology
Background:
- Embryonic development generates diverse cell types from a single zygote.
- Cellular identity is established by transcription factors and epigenetic modifiers.
- Epigenetic memory maintains distinct chromatin states and gene expression.
Purpose of the Study:
- To review the role of histone lysine methylation in epigenetic memory.
- To explain how epigenetic marks are stably maintained through cell division.
Main Methods:
- Literature review of current knowledge on histone lysine methylation.
- Analysis of epigenetic regulatory mechanisms and their maintenance.
Main Results:
- Histone lysine methylation is crucial for establishing and maintaining epigenetic states.
- Epigenetic modifications, beyond DNA methylation, are stably inherited.
- These mechanisms ensure cell-type specific gene expression patterns persist.
Conclusions:
- Histone lysine methylation plays a significant role in epigenetic memory.
- Understanding these mechanisms is key to comprehending cellular differentiation and identity.

30.2K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.

Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

00:57Cellular Differentiation
5.7K
How does a complex organism such as a human develop from a single cell? It all starts from a single fertilized egg which gives rise to a vast array of cell types, such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.

01:51Determination
16.3K
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

01:14Maintenance of the ES Cell State
1.9K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

01:29Somatic to iPS Cell Reprogramming
2.1K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...
