HEK293T cells used for flow cytometry were cultured in Dulbecco’s Modified Eagle Medium (DMEM) media (Gibco) supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin at 37°C with 5% CO2 and cells were periodically tested to be mycoplasma negative. The cells were transfected with A3A-INS2 or A3A(E72A)-INS2, or co-transfected with A3A-SPL2N and A3A-SPL2C for 24 hours prior to harvest and staining with γH2AX antibody (BD Pharmigen, 647) and flow cytometry analysis. Cells were gated on FITC and APC using the Fortessa Flow Cytometer (BD Biosciences), and results were analyzed using FlowJo. The gating strategy is exemplified in Extended Fig. 8a.
U2OS cells used for immunofluorescent studies were cultured in Dulbecco’s Modified Eagle Medium (DMEM) media (Gibco) supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin at 37°C with 5% CO2 and cells were periodically tested to be mycoplasma negative. U2OS cells plated on coverslips were transiently transfected with A3A-INS, A3A(E72A)-INS2 or co-transfected with A3A-SPL2N and A3A-SPL2C constructs for 24 hours prior to incubation with γH2AX antibody (Millipore Sigma) and immunofluorescent staining with Alexa Fluor 568 (Invitrogen) and DAPI.

ARA 290 Modulates Schwann Cell Inflammation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Rat RSC96 Schwann cells were grown in complete Dulbecco’s modified eagle medium (DMEM) media (Gibco, Grand Island, NY) containing penicillin (100 U/mL), streptomycin (100 U/mL) and 10% fetal calf serum at 37°C and 5% CO2.
To analyse the effects of ARA 290 on inflammatory cytokine expression by RSC96 Schwann cells, 106 cells were seeded into 6-well cell culture plates in triplicates and cultured overnight. Afterwards cells were washed twice by PBS, and then ARA 290 of different doses were added into the culture with or without 1 µg/ml lipopolysaccharide (LPS) for overnight. Thereafter, mRNA levels of inflammatory cytokines were measured using following primers: TNF-α (sense, TGA TCG GTC CCA ACA AGG A; antisense, TGC TTG GTG GTT TGC TAC GA), iNOS (sense, TCT GTG CCT TTG CTC ATG ACA; antisense, TGC TTC GAA CAT CGA ACG TC) and β-actin (sense, CCG TCT TCC CCT CCA TCG T; antisense, ATC GTC CCA GTT GGT TAC AAT GC).
In Schwann cell proliferation assays, cells were cultured in 1% fetal calf serum and treated with different doses of ARA 290 for 24 h and compared to proliferation of cells in normal 10% fetal calf serum. Cell proliferation was determined by Cell Counting Kit-8 Assay (Dojindo, Kumamoto, Japan) according to the manufacturer’s protocol.

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.
