| Study ID | ST001303 |
| Study Title | TGF-Beta 3 heterozygous mice |
| Study Type | Mice nephropathy in lipotoxic model |
| Study Summary | Transforming growth factor β (TGFβ) family comprises the main player in the development of fibrosis including three isoforms: TGFβ1, TGFβ2 and TGFβ3. TGFβ3 may play an antifibrotic role at the renal level, counteracting the role of TGFβ1, using a mouse model heterozygous for the TGFβ3 gene (TGFβ3+/-). Partial deletion of TGFβ3 causes in the mice albuminuria, loss of glomerular filtration rate, accelerated fibrosis, epithelial-to-mesenchymal transition and increment of glomerular basement membrane thickening. |

Sample Preparation:
| Sampleprep ID: | SP001385 |
| Sampleprep Summary: | 100 μL of kidney tissue homogenate was vortex-mixed with 320 μL of methanol for 2 min, followed by the addition of 80 μL of MTBE for the extraction of nonpolar compounds. Then, vials were rapidly capped and placed on a shaker for 1 h at room temperature. The extracted samples were centrifuged at 4000g for 20 min at 20 °C. For GC−MS analysis, 300 μL of supernatant was evaporated to dryness (SpeedVac Concentrator System, Thermo Fisher Scientific, Waltham, MA). Methoxymation was then performed with 20 μL of O-methoxyamine hydrochloride (15 mg/mL in pyridine) and vigorously vortex-mixed for 5 min. Vials were then incubated in darkness at room temperature for 16 h. For silylation, 20 μL of BSTFA/TMCS (99:1) was added and vortex-mixed for 5 min, and capped vials were placed in the oven at 70 °C for 1 h. Finally, 100 μL of heptane containing tricosane (20 ppm) as internal standard (IS) was added to each vial prior to injection. For LC−MS analysis, 90 μL of supernatant was transferred to an ultra-high-performance liquid chromatography−mass spectrometry. |
