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.

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 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 radiation (FIR), a subdivision of the electromagnetic spectrum, has been proved to be beneficial for long-term effects of tissue healing, anti-inflammation, promoting growth, modulating sleep, acceleration of microcirculation, and pain relief. We attempt to study whether FIR would be beneficial for renal proximal tubule cell (RPTC) cultivation and renal tissue engineering. We observed the FIR effects on RPTCs, including cell viability, functional characteristics, immunofluorescence presentations, and subcellular findings. And the FIR protective effects would be further examined with HK-2 cell (Human proximal tubule cell line) against cisplatin, a nephrotoxic agent. Our study showed that daily exposure to FIR for 30 minutes could significantly increase rabbit RPTC viability in vitro assessed by MTT assay. FIR is not only beneficial in RPTC cell viability. RPTCs with FIR exposure presented higher expression of Na-K ATPase and GLUT1 (Glucose Transporter 1). The finding was documented with western blot analysis with statistical significance. With Q-PCR, CDK5R1, GNAS, NPPB, and TEK expressions were significantly enhanced. With HK-2 cell, the proximal tubule cell line, FIR had protective effects against cisplatin nephrotoxicity through reducing apoptosis. FIR is a potential photomodulation therapy to facilitate RPTC cultivation with higher cell viability and better functional chanacteristics and would possibly be applied in further nephrotoxicity protection and other cisplatin-sensitive cell protection.

Project description:This SuperSeries is composed of the following subset Series: GSE15259: The effects of far-infrared rays on normal prostate epithelial cells (PrEC) GSE15260: Effects of far-infrared rays on 3 human prostate cancer cell lines GSE16077: Effects of far-infrared rays on human prostate cancer cell line PC-3 FIR stands for far-infrared rays that was reflected and radiated from RB. Refer to individual Series RNA was extracted with Isogen kit (NIPPON GENE CO., LTD. Osaka, Japan) from PrECs, and PC-3 with or without exposure to FIR on the 7th and 12th day of culture. Aliquots of 200 ng of total RNAs were labeled with Cy3- or Cy5- UTP using Agilent Quick Amp Labeling Kit (Agilent Technologies Inc, Tokyo, Japan) according to the manufacturer instructions. The Cy3-labeled probe using RNA from cells treated with DMSO and the Cy5-labeled probe using RNA from cells treated with DNCB for 4.5 hr were mixed, fragmented, and then suspended in GE hybridization buffer in the Gene Expression Hybridization Kit (Agilent Technologies Inc, Tokyo, Japan). The probes were applied to Whole Human Genome Oligo array (Agilent Technologies Inc, Tokyo, Japan), and hybridization, washing, and scanning by Agilent Microarray Scanner were performed according to the manufacturer $B!G (Bs recommended protocol. The images were processed using Feature Extraction Software (ver9.5.3.1, Agilent). For each hybridized spot, background intensity was subtracted and normalized by the global LOWESS normalization method. Dye-swap was performed. More than 2 fold and less than 0.5 fold changes are assigned positive on data analysis. RNA extracted from FIR-treated and non-FIR treated DU145, PC3, and LNCaP on the 21st and 28th day of culture were also treated in the same way except the use of commercially available IntelliGene HS Human Expression chip (TAKARA BIO, Otsu, Japan). Data analysis was performed using the microarray data analysis software, Expressionist (GeneData AG, Basel, Switzerland). Functional analyses were performed and the networks were generated using Ingenuity Pathways Analysis (Ingenuity Systems, CA, USA) cDNA microarray. BRCA1 and associated genes for DNA repair were significantly up-regulated in PrECs on the 7th day, and PC-3 on the 12th day when they were exposed to FIR (Fig. 2). These up-regulated genes were all normalized on the 12th day in PrECs, and there were no significant up-regulation of DNA repair pathway by FIR in DU145 and LNCaP on the 7th and 12th day.

Project description:Early EPCs (eEPCs) appear at less than 1 week in culture dishes, whereas late EPCs (LEPCs) appear late at 2-4 weeks. Distinct angiogenic properties between these two EPC subpopulations have been disclosed by the angiogenesis assay: late EPCs, but not eEPCs, form vascular networks de novo and are able to incorporate into vascular networks. On the contrary, eEPCs, but not late ones, indirectly augment tubulogenesis even when physically separated by a Transwell membrane, implying the involvement of a cytokine-based paracrine mechanism. Microarrays are great tools to “snapshot” the transcriptome profiles, and thus provide deeper insights into gene expressions and microRNA-gene interactions.

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.
