Insights

Downregulating long non-coding RNA AK094457 inhibits vascular smooth muscle cell proliferation and inflammation in atherosclerosis. This gene therapy approach targets the TLR4/MyD88 and Nrf2/HO-1 pathways for potential atherosclerosis treatment.

Area of Science:

  • Cardiovascular Biology
  • Molecular Medicine
  • Gene Therapy

Background:

  • Atherosclerosis is a prevalent global disease requiring novel therapeutic strategies.
  • Gene target therapy presents a promising avenue for treating atherosclerosis.
  • Long non-coding RNAs (lncRNAs) are emerging as critical regulators in cardiovascular diseases.

Purpose of the Study:

  • To investigate the role of lncRNA AK094457 in oxidized low-density lipoprotein (OX-LDL) induced vascular smooth muscle cells (VSMCs).
  • To evaluate the therapeutic potential of downregulating lncRNA AK094457 in an atherosclerosis context.

Main Methods:

  • Utilized shRNA-AK094457-1 to downregulate lncRNA AK094457 expression in OX-LDL-induced VSMCs.
  • Assessed cell proliferation, migration, reactive oxygen species (ROS) levels, and inflammation.
  • Analyzed protein expression related to the TLR4/MyD88 and Nrf2/HO-1 signaling pathways.

Main Results:

  • Downregulation of lncRNA AK094457 significantly inhibited proliferation and migration of VSMCs.
  • Reduced levels of ROS and inflammation were observed following lncRNA AK094457 downregulation.
  • Suppressed expression of TLR4/MyD88 pathway proteins and enhanced expression of Nrf2/HO-1 pathway proteins were noted.

Conclusions:

  • Downregulation of lncRNA AK094457 exerts protective effects against OX-LDL-induced cellular damage in atherosclerosis.
  • The therapeutic effects are mediated through modulation of the TLR4/MyD88 and Nrf2/HO-1 signaling pathways.
  • lncRNA AK094457 represents a potential therapeutic target for atherosclerosis treatment.

Nitric Oxide Signaling Pathway01:28

Nitric Oxide Signaling Pathway

Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

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...
