A new scientific breakthrough could dramatically improve cancer treatments by helping bulky, hard-to-deliver drugs enter cells more efficiently.
Researchers from Duke University, the University of Texas Health Science Center at San Antonio, and the University of Arkansas have discovered a way to significantly boost the cellular uptake of a promising class of cancer therapies known as PROTACs. These drugs work by degrading harmful proteins in cells but are often too large to penetrate cell membranes on their own.
The team found that a naturally occurring cell surface protein, CD36, can act as a transporter, helping PROTACs cross the cellular barrier. By modifying the drugs to exploit this transport mechanism, the researchers achieved up to 22.3 times higher drug uptake, resulting in up to 23 times more powerful tumor suppression—all without sacrificing drug stability or solubility. Their findings, published April 17 in Cell, could breathe new life into many large-molecule drugs previously deemed too unwieldy for therapeutic use.
