Project description:High glucose impairs the angiogenic activities of late endothelial precursor cells (EPC). We found that far infrared (FIR) treatment restored partially the activity of late EPC. However, the mechanisms are unclear. We performed gene expression microarray analysis to assess the expression profiles of high glucose-treated late EPC with or without FIR treatment.

However, the mechanisms are unclear. We applied microRNA expression microarrays to assess the microRNA expression profiles of high glucose-treated late EPC with or without FIR treatment. Late EPCs isolated from peripheral blood were cultured in high glucose condition for 48 hours, and then treated with or without FIR radiation for 30 minutes. Total RNA were extracted and evaluated with the Agilent Human miRNA Oligo Microarray R14 V2 chips.

Project description:Far-infrared rays activated DNA repair genes in human prostate cancer cells, PC-3, after 12days' exposure to far-infrared rays. As a far-infrared rays emitter, synthetic/natural rubber (RB) was used. Keywords: comparative genomic hybridization Two-condition experiment,RB-treated vs.non-RB-treated cells.: 2 reference control without RB, independently grown and harvested. One replicate per array.
Project description:Far-infrared rays activated DNA repair genes in human prostate epithelial cells after 7 or 12 days' exposure to far-infrared rays. As far-infrared rays emitter, synthetic/natural rubber (RB) was used.

Project description:We introduce anticancer effect of the far-infrared rays. The growth of three human prostate cancer cells (DU145, PC-3 and LNCaP) was suppressed in vitro only by far-infrared rays. The far-infrared rays induced the gene activation involved in apoptosis that exert positive effects on cancer control. Shima, H. et al. Far-infrared rays control prostate cancer cells in vitro and in vivo. Nature Precedings, hdl:10101/npre.12008.11980.10101 (2008). Keywords: cancer control Twelve samples were analyzed. Each sample was cultured quadricate. One replicate per array. The DU145, PC-3 and LNCaP cell lines were obtained from American Type Culture Collection (Manassas, VA, USA). DU145 cells were maintained in minimum essential medium supplemented with 10% heat-inactivated fetal calf serum, 2 mM L-glutamine, 100 U/ml penicillin G and 0.1 mM non-essential amino acids in an atmosphere of 5% CO2 at 37°C. PC-3 and LNCaP cells were maintained in F-12K medium and RPMI medium with the same supplements, respectively. All three cancer cells were cultured for 21 and 28 days with or without exposure to far-infrared rays. The cells without exposure to far-infrared rays were used as the reference samples (Far-infrared rays-treated vs. non-treated cells). Natural or synthetic rubber/resin (RB) was obtained as far-infrared rays emitter from Yamamoto Corporation (Osaka, Japan). RB consisted of rubber, lime stone and titanium metal powder in a honeycomb structure comprised of micron-sized cells, and had the ability to radiate far-infrared rays (4â25 um). Experimental samples were sandwiched with RBs for 21 and 28 days. Channels 1 were exposed to RB.
