Insights

Dansameum extract (DSE) shows anti-atherosclerotic effects by reducing foam cell formation. DSE down-regulates CD36 and PPAR-γ expression, lowering lipid content in cells and animal models.

Area of Science:

  • Cardiovascular Research
  • Pharmacology
  • Molecular Biology

Background:

  • Atherosclerosis is a leading cause of death, with foam cell formation being a critical step.
  • Foam cell formation is mediated by CD36 and peroxisome proliferator-activated receptor gamma (PPAR-γ) expression.

Purpose of the Study:

  • To investigate the anti-atherosclerotic potential of Dansameum extract (DSE).
  • To determine if DSE down-regulates CD36 and PPAR-γ expression in oxidative low-density lipoprotein (oxLDL)-treated RAW264.7 cells and in ApoE Knockout (ApoE-/-) mice.

Main Methods:

  • DSE was prepared from Salvia miltiorrhiza, Amomum xanthioides, and Santalum album.
  • Immunohistochemistry and RT-PCR were used to analyze protein and mRNA expression.
  • Experiments were conducted on oxLDL-treated RAW264.7 cells and ApoE-/- mice fed a high-fat diet.

Main Results:

  • DSE significantly reduced foam cell formation in both in vitro and in vivo models.
  • DSE treatment decreased CD36 and PPAR-γ expression in oxLDL-stimulated RAW264.7 cells and ApoE-/- mice.
  • DSE regulated heme oxygenase-1 (HO-1) expression and reduced cellular lipid content.

Conclusions:

  • DSE exhibits anti-atherosclerotic properties.
  • DSE effectively regulates foam cell formation by modulating key molecular targets.
  • DSE may serve as a potential therapeutic agent for atherosclerosis.

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Peroxisomes and Mitochondria

Peroxisomes and mitochondria are two important oxygen-utilizing organelles in eukaryotic cells. Mitochondria carry out cellular respiration—the process that converts energy from food into ATP. Peroxisomes carry out a variety of functions, primarily breaking down different substances, such as fatty acids.
The peroxisome is a single membrane-bound cellular organelle that can perform several different functions, including lipid metabolism and chemical detoxification. The enzymes within...

Peroxisomes

Peroxisomes are specialized organelles present in fungi, plant, and animal cells. It can vary in number, size, morphology, and activity depending on the type of tissue and the nutritional state of the cell. For example, cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, have more peroxisomes than other cells in the body. Besides their primary role in breaking down complex organic molecules, peroxisomes can also synthesize specific macromolecules and participate in...

G-protein Coupled Receptors01:21

G-protein Coupled Receptors

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

Internal Receptors01:31

Internal Receptors

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Protein Import into the Peroxisomes01:27

Protein Import into the Peroxisomes

Cells contain membrane-bound organelles called peroxisomes that oxidize organic molecules by transferring hydrogen atoms to oxygen, producing hydrogen peroxide. Peroxisomes enzymatically convert the released hydrogen peroxide into water and oxygen.
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...
