Project description:For the MALDI-MSI experiment, we selected 12 different drugs. The drugs were purchased from the LC Laboratories (Woburn, MA; CAS numbers: dabrafenib: 1195765-45-7, dasatinib: 302962-49-8, erlotinib: 183321-74-6, gefitinib: 184475-35-2, imatinib: 152459-95-5, lapatinib: 388082-78-8, pazopanib: 444731-52-6, sorafenib: 284461-73-0, sunitinib: 557795-19-4, trametinib: 871700-17-3, vatalanib: 212141-54-3) and from SelleckChem (Munich, Germany; CAS numbers: ipratropium: 60205-81-4) with >99% purity and were dissolved in methanol (MeOH, (Chromasolv Plus for HPLC) (Sigma-Aldrich, Steinheim, Germany) at 10 mg/mL concentration. These stock solutions were further diluted with 50% MeOH and five mixtures were generated, each containing four different drug compounds. The spreadsheet in Supporting Information summarizes the composition of the five drug mixtures. A 5 mg/mL solution of α-cyano-4-hydroxycinnamic acid (CHCA, Sigma-Aldrich) dissolved in 50% MeOH containing 0.1% trifluoroacetic acid (TFA, Sigma-Aldrich, Steinheim, Germany) was used as matrix solution.
Project description:HUVECs were purchased from the American Type Culture Collection (ATCC, Manassas, VA, USA) and cultured in an Endothelial Cell Medium (Invitrogen, Carlsbad, CA, USA) containing 5% fetal bovine serum at 37°C in a 5% CO2 incubator. Cells were treated with 30 mM glucose and 0.1 mM palmitic acid (P0500, Sigma-Aldrich, USA) dissolved in 0.5% bovine serum albumin (BSA) for 48 h to simulate HGHF treatment. The Akt inhibitor MK-2206 2HCl was purchased from Selleck Chemicals (S1078, Houston, TX, USA).
Project description:Whole fetal livers were collected from mouse fetuses at embryonic day 14.5 (E14.5), and single-cell suspensions were prepared by successive passage through 18-, 21 and 23-gauge needles. Fetal liver cells were maintained in Dulbecco modified Eagle medium (DMEM; Invitrogen) supplemented with 10% fetal bovine serum (FBS; Invitrogen), 100 U/ml penicillin, 100µg/ml streptomycin, and 50ng/ml recombinant human thrombopoietin (TPO; Peprotech). After 5 days of culture, megakaryocytes were purified using a discontinuous bovine serum albumin gradient (BSA, Sigma–Aldrich; 3%, 1.5%, and 0%). Total RNA was isolated with Tri–Reagent (MRC) following manufacturer’s instructions, and its quality was assessed with ND–1000 Nanodrop (Peqlab) and on a 1.5% agarose gel.
Project description:The same sample of bovine liver extract analyzed using a mobile phase with solvents purchased from different vendors. LC-MS grade water was purchased from Sigma, methanol and isopropanol are purchased from Sigma, Honeywell and Fisher Scientific. Vendor names are randomized and only listed as vendors 1, 2 and 3 in the filenames for confidentiality. The raw data is used in the following preprint: "Vendor-dependent mobile phase contaminants affect neutral lipid analysis in lipidomics protocols" (DOI 10.26434/chemrxiv-2024-r67fv)
Project description:All datasets are generated for evaluation of FLASHDecovn, thus only contain MS1.
Cyto dataset, Bovine Cytochrome C (P62894 UniProt accession number), was purchased from Sigma-Aldrich. Filg dataset, filgrastim, was kindly provided by CinnaGen Co. HPLC-grade H2Oacetonitrile (ACN) and formic acid (FA) were purchased from Meck (Darmstadt, Germany). Thermo_STD dataset, Pierce Intact Protein Standard Mix, containing 6 standard proteins namely Protein G, Protein AG, IGF-I LR3, Thioredoxin, Carbonic Anhydrase II, Exo Klenow was purchased from Thermo Scientific (Bremen, Germany).
Project description:ECM is the physicochemical support for the cells living in the tissue microenvironment. it is important to know the protein contents within the ECM that are critical for extra- and intracellular signaling, cell growth, migration, cell-cell/ECM interactions. The ECM gel derived from the Engelbreth-Holm-Swarm murine sarcoma (commonly known as Matrigel or lrECM) purchased from the Sigma Aldrich in the liquid concentration of 8-12 mg/ml (Lot # 064M4075V) was used for the LC-MS/MS analysis and to prepare the 3D scaffolds used for downstream experiments. The Matrigel mass spectrometry data will be used to compare with those of the decellularized mice mammary tissue ECM/DBT-TMS.
Project description:We performed bulk RNA sequencing analysis of a 3D organoleptic model of human oral mucosa treated with everolimus. The 3D model (tissue) consisted of human normal keratinocytes grown on top of human fibroblasts and was histologically similar to buccal mucosa. The tissue was purchased from MatTek Corporation (Ashland, MA) and cultured in serum free media. The 3D model was maintained for different times in the tissue culture (40 hours and 60 hours from the time received) and treated with different concentration of Everolimus (no drug (0 ng/ml), 32 ng/mL, 64 ng/mL).
