Nature reviews. Cardiology·2017

The ATP-binding cassette transporter A1 (ABCA1) facilitates cholesterol removal, offering potential for treating cardiovascular disease. Transgenic mouse models are crucial for understanding ABCA1

Area of Science:

  • Biochemistry
  • Cardiovascular Science
  • Genetics

Background:

  • ATP-binding cassette transporter A1 (ABCA1) is crucial for cellular cholesterol efflux to apolipoproteins.
  • Defects in ABCA1 cause Tangier disease, highlighting its role in lipid metabolism.
  • ABCA1's antiatherogenic properties suggest therapeutic potential for cardiovascular diseases.

Purpose of the Study:

  • To review recent studies on ABCA1 function using transgenic mouse models.
  • To investigate the role of hepatic versus peripheral ABCA1 in HDL metabolism.
  • To explore ABCA1's impact on apolipoprotein B lipoproteins and atherosclerosis.

Main Methods:

  • Utilizing ABCA1-transgenic (ABCA1-Tg) mouse models.
  • Analyzing plasma HDL levels and reverse cholesterol transport.

  • Assessing apolipoprotein B-containing lipoproteins and atherosclerotic burden.

    • Main Results:

    • Preliminary studies in ABCA1-Tg mice support its therapeutic target validation.
    • New questions have arisen regarding ABCA1's specific functions in different tissues.
    • Investigating tissue-specific contributions of ABCA1 is ongoing.

    Conclusions:

    • ABCA1 is a promising therapeutic target for low HDL syndromes and cardiovascular disease.
    • Transgenic mouse models provide valuable insights into ABCA1 function.
    • Further research is needed to elucidate ABCA1's complex roles in lipid transport and atherosclerosis.
