3D-printers will help scientists in the fight against cancer




It seems that the high availability of 3D-printers will help scientists to study cancer and fight with them. In a joint project of American and British researchers are actively using 3D-printing for the study of DNA molecules.

2D-image of double-stranded DNA molecules have long been helpful in cancer research. Quite another thing – G-quadruplexes or chetyrehtsepochechnye DNA sequences which are very difficult to portray on a piece of paper and they just need 3D-incarnation for clarity.

Within the walls of 3D-printing lab, located at the University of Alabama, has successfully recreated the physical 3D-model of the complex molecular structures. It will allow scientists to better understand the principles of pancreatic cancer, as well as speed up the process of finding methods to treat it.

The essence of this project is to collect data of X-ray analysis of G-quadruplex molecules and the transformation of the results into a full 3D-computer model, suitable for printing.

“Transfer of data array into a sequence suitable for 3D-printing for us was truly a serious challenge. Now that problem is solved, we are very much further along in our research. After 3D-model of G-quadruplex allows us to see all the symmetry, faces and edges inside the molecular structure – shared his joy with journalists Skalfani Dr. Vincent. ”

Scientific studies have shown that exposure to G-quadruplexes with certain compounds can inhibit or stabilize the development of cancerous tumors in the pancreas. 3D-printed models currently being used as tools for research prior to the actual clinical trials. They allow scientists to better imagine something with which they are dealing, as earlier they had to deal only with the printed paper schemes.
