Treatment with caffeine and DNP also considerably improved oxidative rate of metabolism and total metabolic process weighed against control. Caffeine similarly increased metabolism and mitochondrial content compared with DNP. Conclusion: This work identified that both caffeine and DNP significantly induce PGC-1, and increase both metabolism and mitochondrial content in skeletal Rabbit Polyclonal to MPRA muscle. rhabdomyosarcoma cells were purchased from ATCC (Manassas, VA) and were cultured in Dulbeccos Modified Eagles Medium (DMEM) containing 4500 mg/L glucose and supplemented with 10% heat-inactivated fetal bovine serum (FBS) and 100 U/mL penicillin/streptomycin in a humidified 5% CO2 atmosphere at 37C. Trypsin-EDTA at 0.25% was used to Arranon detach the cells for splitting and re-culturing. Stock DNP and caffeine from Sigma (St. Louis, MO) were dissolved in ethanol to create treatment solutions of 250 M and 500 M determined through pilot experiments with DNP to significantly increase PGC-1 RNA. RNA extraction and quantification PGC-1 mRNA expression was quantified by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR). Cells were plated into 12-well plates at a density of 5 105 cells/well; treated with either ethanol control (0.1% final concentration) DNP at 250 M or 500 M, or caffeine at 250 M or 500 M; and incubated as described above for 16 or 24 hours. Following incubation, total cell RNA was extracted using RNeasy Kit from Qiagen (Valencia, CA) per manufacturers protocol. Total RNA was quantified by Nanodrop spectrophotometry. cDNA was synthesized from 5000 ng total RNA using the Retroscript RT kit from Ambion (Austin, TX) according to manufacturers instructions. PCR primers were designed using Primer Express software from Invitrogen (Carlsbad, CA) and synthesized by Integrated DNA Technologies (IDT, Coralville, IA). For PGC-1, the forward primer was 5-ACCAAACCCACAGAGAACAG-3 and the reverse primer was 5-GGGTCAGAGGAAGA GATAAAGTTG-3. Amplification of PGC-1 was normalized to the housekeeping gene, test of mean difference between groups generated by Cp. WST-1 cell metabolism, oxygen consumption, extracellular acidification, and flow cytometry were analyzed using ANOVA and pairwise comparisons comparing treatments with control. WST-1 cell metabolism assay data was transformed to show relative metabolism with control = 1. Chi-square test was used to analyze total Arranon metabolic capacity indicated by OCR/ECAR. Cell viability was analyzed using Student test. Values of 0.05 indicated statistical significance in all tests used, and Bonferroni adjustment for error from multiple pairwise comparisons was used. Results PGC-1 induction and expression PGC-1 RNA was significantly induced in cells treated with either DNP or caffeine compared with the control group. Treatment with DNP at 250 and 500 M for 16 hours significantly induced PGC-1 expression almost 10 fold (Fig. 1A). Treatment Arranon with caffeine at 500 M for 16 hours also significantly induced PGC-1 expression. Following 24-hour treatment both DNP and caffeine at 250 and 500 M significantly induced PGC-1 expression (Fig. 1B). Open in a separate window Figure 1 Changes in PGC-1 RNA expression. (A) Relative RNA expression of PGC-1 of rhabdomyosarcoma cells treated with either ethanol control (final focus 0.1%), DNP in 500 or 250 M, or caffeine in 500 or 250 M for 16 hours with control = 1. Records: Comparative RNA manifestation of PGC-1 of cells treated as referred to above every day and night with control = 1. * shows 0.05, ** indicates 0.01, and *** indicates 0.001 weighed against control. To determine PGC-1 proteins, we assessed fluorescence of cells stained having a PGC-1 particular antibody via movement cytometry. Just like RNA, PGC-1 protein was also significantly raised in cells treated with either caffeine or DNP for 16 or a day. Pursuing treatment for 16 hours, both caffeine and DNP at 500 M considerably increased PGC-1 proteins staining weighed against control (Fig. 2A). After a day of treatment, both DNP and caffeine at 250 or 500 M considerably increased PGC-1 proteins staining weighed against control (Fig. 2B). Improved PGC-1 protein amounts were confirmed using microscopy which verified that treatment with DNP or caffeine every day and night considerably induced PGC-1 proteins manifestation (Fig. 2C).
