Summary
Researchers mapped gene networks controlling heart formation. They found that MEF2C (myocyte enhancer factor 2C) activity creates specific gene networks for different heart segments, revealing intricate developmental logic.
Area of Science:
- Developmental Biology
- Genetics
- Molecular Biology
Background:
- Heart formation relies on precise transcriptional regulation.
- Understanding the gene regulatory networks governing cardiac development is crucial.
Purpose of the Study:
- To analyze the role of MEF2C in heart formation.
- To computationally reconstruct downstream gene regulatory networks controlled by MEF2C.
Main Methods:
- Characterization of MEF2C's temporal effects on mRNA profiles.
- Analysis of MEF2C's impact on chromatin structure.
- Computational reconstruction of gene regulatory networks.
Main Results:
- MEF2C is a key driver of heart formation.
- Gene regulatory networks reconstructed were specific to different heart tube segments (inflow tract, chambers, outflow tract).
- Detailed insights into the network logic of heart development were obtained.
Conclusions:
- MEF2C orchestrates segment-specific gene regulatory networks during heart development.
- This study provides a fine-grained view of the molecular mechanisms underlying heart formation.
- The findings advance our understanding of cardiac developmental biology.

2.1K
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

1.4K
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

02:23Master Transcription Regulators
7.7K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

3.3K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
