Study Title | MuRF1-Related Metabolic Alterations in HL-1 Cardiomyocyte Induced by Cyclic Stretch |
Study Type | Cardiomyocyte cell culture |
Study Summary | We collected cell media and performed GC-MS non-targeted metabolomics to identify the role of MuRF1 in the dynamic metabolic changes in cardiomyocytes. |

Collection:
Collection ID: | CO000956 |
Collection Summary: | Media harvested at 14, 30, and 60 min post stretch (1Hz, 15%) |
Collection Protocol ID: | None |
Collection Protocol Comments: | Non-targeted metabolomics analysis. After HL-1 cells were cultured for 16 h in specialized 6well BioFlex culture plates in Claycomb medium, medium was changed to DMEM supplemented 1% penicillin-streptomycin and 10% serum. Transient knockdown of MuRF1 was carried out using recombinant Ad.shRNA MuRF1 at MOI 30. After transduction for 48 h, HL-1 cells were used for mechanical stretch at 15% strain and for different times (15, 30, and 60 min) in a computer-regulated Flexcell FX-5000 Compression System (Flexcell International Corporation, Hillsborough, NC). Non-stretch cells (0 min) were used as the control. After HL-1 cells were stretched, HL-1 cells (at 0 and 60 min) and DMEM medium (at 0, 15, 30, and 60 min) were collected for GC/MS measurement of metabolites, and samples were placed on dry ice/stored at -80C. Samples were then analyzed by GC/MS, as previously described [24]. The raw, transformed, and sorted data used for each of the three comparisons in the metabolomics analyses can be found in Supplemental Table 1. Up to 1 missing value per group was imputed using lowest value in the same group, with groups missing 2 or more excluded from the analysis. The data obtained in this study will be accessible at the NIH Common Fund’s Data Repository and Coordinating Center (supported by NIH grant, U01-DK097430) website, http://www.metabolomicsworkbench.org. |
