title: Impact of a mechanical massage on gene expression profile and lipid mobilization in female gluteofemoral adipose tissue.
abstract: BACKGROUND
  Gluteofemoral adipose tissue areas are known to be poorly metabolically reactive. Mechanical massage has previously been reported to show morphological and functional impact on this tissue. The present study was carried out to delve more deeply into the mechanistic considerations regarding the incidence of a mechanical massage technique on gene expression profile and β-adrenergic-mediated lipid mobilization in female femoral adipose tissue.
  
  
  METHODS
  Twelve premenopausal healthy women were included and received 12 sessions of calibrated mechanical massage (Endermologie®). Total RNA was extracted from femoral adipose tissue biopsies for gene expression studies. Microdialysis was carried out in the femoral adipose tissue in order to assess lipolytic responsiveness (via glycerol determination) and changes in local blood flow following perfusion of a lipolytic agent, isoproterenol. Evaluations were performed before and after the 6-week experimental period.
  
  
  RESULTS
  Mechanical massage initiated important modifications in gene expression profile. The lipid-mobilizing effect of isoproterenol was enhanced after the experimental period. Basal local blood flow and isoproterenol-induced vasodilatation were also improved.
  
  
  CONCLUSIONS
  The protocol of mechanical massage used in the study promoted noticeable changes in the expression of genes involved in metabolic pathways. The lipolytic and local adipose tissue blood flow responses initiated by isoproterenol were significantly enhanced.
