Science Daily carries an article about a new approach to cancer treatment (more specifically, cancer treatment resistance):

Every year thousands of patients die from recurrent cancers that have become resistant to therapy, resulting in one of the greatest unsolved challenges in cancer treatment. By tracking the fate of individual cancer cells under pressure of chemotherapy, biologists and bioengineers at Harvard Medical School studied a network of signals and molecular pathways that allow the cells to generate resistance over the course of treatment.

Using this information, a team of applied mathematicians led by Professor Mohammad Kohandel at the University of Waterloo, developed a mathematical model that incorporated algorithms that define the phenotypic cell state transitions of cancer cells in real-time while under attack by an anticancer agent. The mathematical simulations enabled them to define the exact molecular behavior and pathway of signals, which allow cancer cells to survive treatment over time.

[...] The approach the bioengineers took was to build a single nanoparticle, inspired by computer models, that exploit a technique known as supramolecular chemistry. This nanotechnology enables scientists to build cholesterol-tethered drugs together from "tetris-like" building blocks that self-assemble, incorporating multiple drugs into stable, individual nano-vehicles that target tumors through the leaky vasculature. This 2-in-1 strategy ensures that resistance to therapy never has a chance to develop, bringing together the right recipe to destroy surviving cancer cells.

The paper, "Rationally Designed 2-in-1 Nanoparticles Can Overcome Adaptive Resistance in Cancer," (DOI: 10.1021/acsnano.6b00320) was published online on June 3, 2016 in the leading nanotechnology journal ACS Nano.
