Nilotinib and Imatinib Effects on NF1 Schwann Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
The donor of the study specimen was a 12-year-old female NF1 patient, diagnosed according to the modified National Institutes of Health criteria [18] (link). A parent of the patient gave informed written consent in addition to assent from the patient. The Institutional Review Board approved the study (OB-061/05). Her PNF was operated at the Department of Maxillofacial Surgery, University Hospital Hamburg-Eppendorf. A part of the tumor was kept in Hanks buffered saline and delivered into the laboratory for cell culture and for xenografting. Schwann cells from the PNF were cultured and identified as previously described [16] (link).
After ensuring purity of 85%, PNF-derived Schwann cells were treated with nilotinib and imatinib (Novartis Pharma AG, Switzerland), each at 0, 5, 10, 15 and 20 µM for 10 days. Cell proliferation and viability assays were performed as previously described [16] (link).

Check if the same lab product or an alternative is used in the 5 most similar protocols
Nilotinib (TKI) supplied by Novartis Pharmaceuticals, and CXCR2 inhibitor (SB225002) purchased from Selleckchem (cat no. S7651, Houston, TX) were stored in 10mM dimethylsulfoxide (DMSO) at 20°C. Recombinant mouse TNFα (animal-free, clone MP6-XT22, cat. no. 718004, BioLegend, San Diego, CA) was reconstituted in water and stored at −20°C. Undiluted TNFα neutralizing antibody (InVivoMAb anti-mouse TNFα, clone XT3.11, cat no. BE0058, BioXCell, West Lebanon, NH) was stored at 4°C, and reconstituted in InVivoPure pH 8.0 dilution buffer just before use.

High-grade Glioma Cell Culture Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
For high-grade glioma primary cell cultures treatment assays, cells were passaged and plated in a 96-well plate at 2,000 cells/well in triplicate per condition. At 24 hours, cells were treated with chemotherapeutic agents, siRNA, or control, and assessed for viability 72 hours later using the Cell Titer Glo Assay (Promega) [28 (link)]. ON-TARGET PLUS siRNAs (GE Healthcare Dharmacon) against PDGFRA (J003162-11; J003162-12) and FGF2 (J006695-05; J006695-06) were used according to manufacturer's protocol. Chemotherapy was administered at a range of concentrations (0.01-1000 μM) based on previously published data: temozolomide (Sigma), CCNU (Sigma), Suberanilohydroxamic acid (SAHA), imatinib (Novartis), nilotinib (Novartis), and dasatinib (Bristol-Myers Squibb). Dose response curves were plotted using GraphPad Software, and IC50 was calculated as the dose at which there was a 50% reduction in cell proliferation form untreated cells.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
