ONC212

Cell experiment:

All pancreatic cancer cell lines are treated with ONC201 or ONC212 at the indicated doses and time-points. Post-treatment, both floating and adherent cells are collected, fixed in 70% ethanol and stained with propidium iodide in the presence of ribonuclease A. Flow cytometric data is collected using a flow cytometer. The sub-G1 fraction (apoptotic) is quantified, and analysis is performed to quantify the distribution of cells in G1, S and G2-M phases of the cell cycle utilizing[2].

Animal experiment:

Six- to seven-week-old female athymic nu/nu mice are used in this study. A total of 3 to 5×106 luciferase-expressing cells are suspended in 50 μL of PBS mixed with 50 μL of Matrigel and subcutaneously injected into the rear flanks of the mice. When tumor volume reaches an average of 100 to 150 cm3, mice are randomly assigned to the indicated control or treatment groups. ONC201 and ONC212 are delivered in a solution of 10% DMSO, 20% Kolliphor®EL and 70% PBS by oral gavage. The length (L) and width (W) of the tumors are measured 1 to 2 times a week using a digital caliper, and the volume of the tumor is calculated. Mice are also weighed once a week to monitor signs of drug toxicity[2].
