Check if the same lab product or an alternative is used in the 5 most similar protocols
MNT-1 cells were plated in 6-well plates at a concentration of 2 x 105 cells per well and allowed to adhere overnight. Cells were then incubated with varying concentrations of YM-201636 (Cayman Chemical), Apilimod (US Biological), or vehicle control (DMSO) in normal MNT-1 media. At the conclusion of the treatment, cells were lysed with RIPA buffer for downstream analysis. In treatment assays that exceeded 48 hours, media containing drug was refreshed every 48 hours.

MEFs (WT and p32KO) were obtained in our laboratory (Yagi et al, 2012). All cell lines were cultured in Dulbecco’s modified Eagle medium (DMEM; 1,000 mg/l glucose; Sigma–Aldrich, St. Louis, MO, USA) supplemented with 10% FBS at 37°C in a humidified atmosphere with 5% CO2. MEFs were incubated with the Nampt inhibitor, FK866 (10 nM; Selleck Chemicals Llc, Houston, TX, USA), for 24–48 h in 5% CO2 at 37°C, followed by measurement of total cellular NAD+ and NADH content using the NAD/NADH‐Glo™ Assay (Promega). YM201636 (13576) was purchased from Cayman Chemical. These compounds were solubilized in DMSO (Sigma–Aldrich, D8418), which was used as vehicle control.

MTT Assay for Cell Viability

Check if the same lab product or an alternative is used in the 5 most similar protocols
For drug sensitivity evaluation, cells were seeded in a 96-well plate at 4000 cells/well. The next day, cells were incubated at 37 °C with different concentrations of the test compounds. Control cultures were incubated with dimethyl sulfoxide (DMSO). After 48 or 72 h, media were replaced with fresh media supplemented with MTT (Sigma) at a final concentration of 0.5 mg/mL. After 1.5 h, media were removed and formazan crystals were dissolved with 100 μl of DMSO. Absorbance at 570 nM was read in the spectrophotometer (TECAN Infinite M200). The drugs used in this assay were PAC-1 (S2738, Selleckchem), YM201636 (ref. 13576, Cayman Chemical), and enzastaurin (ref. HY-10342, MedChemExpress).
For viability assays after RNA interference, cells were seeded at 4000 cells/well and transfected at the same time as explained in the previous section. After 6 h, media were replaced with fresh new media. MTT assay was performed as explained above each day and viability was compared to T0. All experiments were repeated at least three times with different cell passage number, with three replicates per experiment.

Evaluating YM201636 Effects on NSCLC Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
To compare the effects of YM201636, we used three NSCLC cell lines (Calu-1, H1299, and HCC827) with different genotypic backgrounds. Calu-1 and H1299 are carcinoma cell lines carrying homozygous TP53 deletion and lack of expression of p53 protein. HCC827 cell line possesses EGFR mutation (exon19del E746-A750), which leads to constitutively activated EGFR.
All cell lines were obtained from the American Type Culture Collection (ATCC, Manassas, USA). Cell culture media and supplements were obtained from Biological Industries (Bio Ind. Kibbutz Beit Haemek, Israel). Calu-1 cells were cultured in DMEM (Dulbecco’s modified Eagle’s medium); HCC827 and H1299 cells were cultured in RPMI-1640 medium in a humidified 37 °C incubator with 5% CO2. Both medias were supplemented with 10% FBS (fetal bovine serum), 1% L-glutamine, and penicillin-streptomycin.
YM201636 was obtained from Cayman Chemical (#13576) and dissolved in DMSO (final concentration 10 mM). For mRNA expression analysis primer, probe and enzymes were purchased from Roche Applied Science (Mannheim, Germany).

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.
