Regulation of the Cardiovascular System01:27

Regulation of the Cardiovascular System

The regulation of the cardiovascular system allows the body to adapt to various demands and maintain homeostasis.
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
Development of Blood Vessels01:07

Development of Blood Vessels

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...
Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

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 hydroxylase and factor...
Mechanism of Filopodia Formation01:39

Mechanism of Filopodia Formation

Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...
Clot Retraction and Fibrinolysis01:16

Clot Retraction and Fibrinolysis

After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.
Blood Studies for Cardiovascular System I: Cardiac Biomarkers01:20

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Genetics

Background:

  • Filamins are large cytoplasmic proteins essential for actin cross-linking and signal transduction via integrin receptors.
  • Emerging evidence shows filamins interact with numerous proteins, including transcription factors and molecules regulating cell signaling, adhesion, and motility.
  • Filamins are also found in the cell nucleus, suggesting broader roles beyond cytoplasmic functions.

Purpose of the Study:

  • To update the understanding of cardiovascular phenotypes associated with filamin gene mutations.
  • To review cardiovascular abnormalities in patients and mouse models with filamin deficiencies.
  • To highlight the role of filamin-interacting proteins in cardiovascular development and disease.

Main Methods:

  • Review of clinical data from patients with filamin gene mutations.
  • Analysis of phenotypes in mouse models deficient in filamins.
  • Examination of cardiovascular phenotypes in mice lacking filamin-interacting proteins.

Main Results:

  • Filamin mutations are associated with a spectrum of cardiovascular malformations.
  • Loss of filamin function in mice leads to distinct cardiovascular defects.
  • Deficiencies in filamin-interacting proteins also manifest cardiovascular phenotypes.

Conclusions:

  • Filamins play a critical role in cardiovascular development and integrity.
  • Understanding filamin interactions is key to deciphering the etiology of filamin-associated cardiovascular disorders.
  • Further research into filaminopathies is warranted to elucidate mechanisms and potential therapeutic targets.
