Insights

Src-family kinases (SFKs) are crucial for heart function and homeostasis. Their altered activity influences cardiovascular diseases, making them potential biomarkers and therapeutic targets.

Area of Science:

  • Cardiovascular Biology
  • Molecular Cardiology
  • Biochemistry

Background:

  • Src-family kinases (SFKs) are non-receptor tyrosine kinases ubiquitously expressed in various cell types.
  • SFKs play a critical role in signal transduction pathways governing cardiac physiological and pathological processes.
  • SFK activity is intrinsically linked to maintaining cardiovascular homeostasis.

Purpose of the Study:

  • To review the fundamental information regarding SFKs.
  • To update the understanding of SFKs' roles in the development of cardiovascular diseases (CVDs).
  • To highlight the potential of SFKs as biomarkers and therapeutic targets for CVDs.

Main Methods:

  • Literature review of studies on SFKs in cardiovascular physiology and pathology.
  • Analysis of SFK involvement in cellular processes like growth, differentiation, movement, and function.
  • Examination of SFK regulation of electrophysiologic signals in the heart.

Main Results:

  • SFK phosphorylation states are altered by various injury factors and stress.
  • SFKs modulate diverse cardiac pathological conditions, including hypertension, coronary heart disease, and cardiomyopathy.
  • SFKs regulate critical cellular functions and electrophysiologic signals in the heart.

Conclusions:

  • SFKs are integral to cardiac function and homeostasis.
  • Dysregulated SFK activity contributes significantly to the pathophysiology of multiple cardiovascular diseases.

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Receptor Tyrosine Kinases

Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Protein Kinases and Phosphatases

Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.
Protein kinases
Many proteins in the cell are regulated by phosphorylation, the addition of a phosphate group. A family of enzymes called kinases...
