Somatic to iPS Cell Reprogramming01:29

Somatic to iPS Cell Reprogramming

2.4K
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...

Methods of Nuclear Reprogramming

2.0K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...

Interactions Between Signaling Pathways

7.0K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Introduction to Nuclear Reprogramming

2.2K
Nuclear reprogramming is the process of switching gene expression of one cell type to that of another cell type, usually from a differentiated cell state to an undifferentiated cell state. Differentiation occurs during processes such as development and morphogenesis, tissue regeneration, and malignancy. Cells can also be artificially induced to reprogram their gene expression by techniques such as nuclear transfer, induced pluripotency, and cell fusion. Such techniques have many applications in...

Epigenetic Regulation01:37

Epigenetic Regulation

3.5K
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.

Area of Science:

  • Genomics
  • Molecular Biology
  • Bioinformatics

Background:

  • Binding motifs are crucial for regulating gene transcription and translation.
  • Sequence alterations like mutations and polymorphisms can create or eliminate these binding motifs, termed 'somatic motifs'.
  • A comprehensive resource for somatic motifs has been lacking.

Purpose of the Study:

  • To create the first comprehensive database of somatic motifs.
  • To identify millions of somatic motifs resulting from various sequence alteration mechanisms.
  • To highlight novel somatic motifs with potential biological significance.

Main Methods:

  • Analysis of large-scale sequence alteration data from major consortiums.
  • Identification of somatic motifs, including those for transcription factors, RNA-binding proteins, and microRNA interactions.
  • Curation of millions of somatic motifs into a centralized database.

Main Results:

  • Identification of millions of somatic motifs across diverse sequence alteration types.
  • Discovery of numerous novel somatic motifs, many occurring at high frequencies.
  • Cataloging of somatic motifs affecting transcription factors, RNA-binding proteins, and microRNA binding sites.

Conclusions:

  • The developed database represents a significant advancement in understanding sequence-driven gene regulation.
  • Identified somatic motifs, particularly novel and frequent ones, are strong candidates for further mechanistic studies.
  • This resource will facilitate research into the biological and disease-related consequences of altered binding motifs.
