Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

2.7K
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...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

7.8K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Eukaryotic Transcription Activators

11.2K
Transcription activators are proteins that promote the transcription of genes from DNA to RNA. In most cases, these proteins contain two separate domains ‒ a domain that binds to DNA and a domain for activating transcription; however, in some cases, a single domain is responsible for both binding and activation of transcription, as seen in the glucocorticoid receptor and MyoD.
The binding domains are capable of recognizing and interacting with regulatory sequences on the DNA. These...

Regulation of the Unfolded Protein Response

2.6K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

General Transcription Factors01:30

General Transcription Factors

5.5K
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Area of Science:

  • Molecular biology
  • Insect physiology
  • Aerospace biology

Background:

  • Migratory flight in insects is energetically demanding and requires significant muscle function.
  • Hypoxia-inducible factors (HIFs) are key regulators of cellular response to low oxygen conditions.

Discussion:

  • This study investigates the role of a hypoxia-associated gene in insect muscle protection during flight.
  • The gene's protective function operates independently of oxygen levels, suggesting a novel mechanism.

Key Insights:

  • A hypoxia-response gene safeguards insect flight muscles.
  • This protection mechanism is non-oxygen dependent, challenging previous assumptions about hypoxia-related pathways.

Outlook:

  • Further research can explore the specific non-oxygen dependent pathways involved.
  • Understanding this mechanism could have implications for muscle physiology and bioenergetics in various organisms.
