5‐ethynyl‐20‐deoxyuridine (EdU) incorporation assay kit (Ribobio, Guangzhou, China) was used according to manufacturer's instruction. 1× 104 cells per well were seeded in a 96‐well plate and incubated overnight and then replaced by 0, 30, 60 μmol L−1 MPA, respectively. After 48‐h incubation, 50‐μmol L−1 EdU was added for 4 hour before fixation, permeabilization, and staining. Finally, cell nuclei were stained with 1 × Hoechst nuclear dye for 30 min and then detected by fluorescence microscopy.

Cell viability was determined using the colony formation assay, 3‐(4, 5‐dimethylthiazol‐2‐yl)‐2, 5‐diphenyltetrazolium bromide (MTT) assay (Sigma, St. Louis, MO, USA) and Celltiter‐Glo assay (Promega, Madison, WI, USA). The 5‐ethynyl‐20‐deoxyuridine (EdU) incorporation assay kit (RiboBio) was used to detect nuclear replication according to the manufacturer’s instructions. Propidium iodide (PI) was utilized to stain ethanol‐treated cells. Next, the cell cycle distribution was detected using a FACSCalibur flow cytometer (BD Biosciences, Franklin Lakes, NJ, USA).

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.
