Methylation Regulation Analysis in HCC

Check if the same lab product or an alternative is used in the 5 most similar protocols
For methylation regulation analysis, HCC cell lines were split to low density (30% confluence) 12 h before treatment. Cells were treated with 5-Aza-2′-deoxycytidine (DAC, Sigma, St. Louis, MO, USA) at a concentration of 2 μM in the growth medium, which was exchanged every 24 h for a total of 96 h and cultured at 37 °C in a 5% CO2 incubator. At the end of the treatment period, cells were prepared for extraction of total RNA. To verify the role of TMEM176A in ERK signaling, SCH772984, an ERK inhibitor, was added to TMEM176A knocking down SNU387 and SNU475 cells at 1 μm and 4 μm for 24 h (MedChemExpress, Monmouth Junction, USA) [21 (link)].

Cell viability assay using MTT 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (BioChemica, Applichem GmbH, Darmstadt, Germany) was performed. A total of 3000 MV3 cells were seeded as triplicates at a total volume of 90 µL per well of 96-well plates (Sarstedt AG) either coated with COL1 or left uncoated. After an incubation of 24 h, cells were treated with pathway inhibitors (tanzisertib, SCH772984, or trametinib) (MedChemExpress LLC, Monmouth Junction, Houston, TX, USA) as well as a dilution series of doxorubicin or mitoxantrone (10−4.5 to 10−8.5 M). After an incubation of 72 h, a MTT solution (20 µL, 5 mg/mL) was added for 1 h at 37 °C and 5% CO2. After removing the supernatant, formazan was solubilized in 200 µL of DMSO (Carl Roth GmbH, Karlsruhe, Germany). Plates were analyzed using a plate reader (Thermo Multiscan EX, Thermo, Schwerte, Germany) at 570 nm, with background subtraction at 690 nm. Data were normalized to DPBS as 100% viability.

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.
