title: The effect of regular aerobic exercise on reverse cholesterol transport A1 and apo lipoprotein a-I gene expression in inactive women.
abstract: BACKGROUND
  Atherosclerotic cardiovascular disease is currently a cause of mortality in some parts of the world. The ATP-Binding Cassette Transporter (ABCA1) gene prepares instructions to produce the ATP-binding cassette transporter protein whose operation is for export of phospholipids and cholesterol, outside cells where they are limited to Apolipoprotein A1 (apoA1). Increased ABCA1 activity could inhibit atherosclerosis.
  
  
  OBJECTIVE
  In the present study, the effect of aerobic exercise was investigated on gene expression and biochemical parameters.
  
  
  METHODS
  The participants included 36 inactive women, which were randomly assigned to control (CON) and experimental (EX) groups. The EX group performed 12 weeks of aerobic exercise and the CON group remained inactive. Fasting blood samples were collected 24 hours before the first session and 48 hours after completion of the course. The ABCA1 and APOA1 gene expressions were measured using semi-quantitative-RT-PCR. Data were analyzed by the SPSS software (version 18).
  
  
  RESULTS
  A significant increase in blood ABCA1 (EX group P < 0.002, t = - 9.876) and Apo A-I (EX group P < 0.05, t = 2.76) gene expression was shown following the 12 weeks of training. Plasma high-density lipoprotein-cholesterol (HDL-C) concentration increased (P < 0.001, t = 4.90 respectively) while plasma low-density lipoprotein-cholesterol (LDL-C) concentration decreased (P < 0.001, t = 4.27) in the EX group compared with the CON group.
  
  
  CONCLUSIONS
  Aerobic exercises can increase ABCA1 and APO-A1 gene expression. Induction of these genes can effectively prevent cardiovascular disease.
