Microwave hyperthermia treatment increases heat shock proteins in human skeletal muscle

Abstract

Objective: To test the hypothesis that microwave hyperthermia treatment (MHT) increases heat shock proteins (HSPs) in the human vastus lateralis muscle.

Methods: Four untrained healthy male volunteers participated in this study. The lateral side of the thigh of one leg (heated leg) was heated with a microwave generator (2.5 GHz, 150 W) for 20 min. At 1 day after the MHT, a muscle sample was taken from the heated leg. A control sample was taken from the unheated leg on another day of the MHT. For both legs, HSP90, HSP72 and HSP27 levels were compared.

Results: The HSP90, HSP72 and HSP27 levels in heated legs were significantly higher than those in control legs (p<0.05).

Conclusions: Application of MHT can increase the levels of several HSPs in human skeletal muscle.

  • HSP, heat shock protein
  • MHT, microwave hyperthermia treatment
  • MyHC, myosin heavy chain
