SK-N-SH cells were purchased from the American Type Culture Collection (ATCC) and cultured using EMEM medium (ATCC) complemented with 10% FBS (Thermo Fisher Scientific). Cells were differentiated for 48 h using 6 μM of all-trans retinoic acid (Sigma-Aldrich).
After harvesting, total RNA were extracted using Tripure isolation reagent (Sigma-Aldrich), treated with DNase I (DNAfree, Ambion) for 30 min at 37 °C and reverse-transcribed (RT) using M-MLV reverse transcriptase and random primers (Invitrogen). Before PCR, all RT reaction mixtures were diluted at 2.5 ng μL of initial RNA. PCR reactions were performed using GoTaq polymerase (Promega).
MCF7 cells were cultured as described in36 . RT-PCRs were performed using the same protocol as for SK-N-SH cells.

Cytotoxicity Assay of Compound in Human Fibroblasts

Check if the same lab product or an alternative is used in the 5 most similar protocols
ATCC CCL-110 cell line (normal, human fibroblasts derived from skin) was used in the experiment. Cells were cultured in EMEM medium (ATCC) and seeded in 96-wells plate for 24 h. Incubation with tested compound at the chosen concentrations: 0.109, 0.218, 0.437, 0.655, 0.873 µM and 1.091 µM (compound was dissolved in methanol) lasted 48 h. Final methanol concentration in each well was 1 µL per 100 µL of medium. EMEM medium with the addition of 1 µL methanol was used as a control and a positive control was pure methanol. After 48 h of incubation, the cytotoxicity test was carried out according to Vybrant MTT Cell Proliferation Assay Kit: 10 µL of the 12 mM MTT stock solution was added to the cells and further incubated at 37 °C for 4 h. After incubation, not all medium but 25 µL was removed from the wells and 50 µL of DMSO was added. Plates were incubated for 10 min at 37 °C and absorbance at 540 nm was read [27 (link),28 (link),29 (link)].

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.
