title: [The role of protein kinase SAPK/JNK in cell responses to low-intensity nonionizing radiation].
abstract: The effect of low-intensity lases light (0.2 mW/cm2, 632.8 nm, exposure time 1 min) or centimeter waves (8.15-18 GHz, 1 W/cm2, exposure time 1 h) on PhosphoSAPK/JNK production in mice lymphocytes was investigated. Normal isolated spleen lymphocytes or cells incubated previously with geldanamycin, an inhibitor of heat shock protein 90 (HSP90), were used in the experiments. A significant stimulation of PhosphoSAPK/JNK production in lymphocytes after treatment with laser light or microwaves has been shown in both cell models. It was proposed that the activation of SAPK/JNK signal pathway plays one of the central roles in cellular stress response to low-power nonionizing radiation.
