New Tools for Fighting Cancer: A Breakthrough in Targeting NSD2 Proteins

Scientists have made a significant discovery in the fight against cancer. They've created new compounds that can destroy specific forms of a protein called NSD2, which plays a role in cancer development. NSD2 comes in three versions due to a process called alternative splicing: long, short, and RE-IIBP. Previously, researchers could only target the long and short versions using certain molecules. The RE-IIBP version, however, was left out because it lacks a specific part called PWWP1. But this version is also crucial in cancer, so scientists needed new tools to study it. They made 31 new compounds that link to a part of NSD2 called the SET domain. One of these, called ND-L11B, can destroy both the long and RE-IIBP versions of NSD2 at the same time. This is a big deal because destroying these proteins can slow down cancer growth. ND-L11B also has another benefit: it stops cancer cells from growing faster than normal cells. This makes it a potential start for creating new treatments for cancer. Moreover, these new tools can help scientists understand what different versions of NSD2 do in cancer. They also show that using certain types of amine chemicals can be useful for targeting specific proteins.
