00:00The molecular key that only attacks cancer when needed.

00:04Imagine a key that only unlocks a door when it's absolutely necessary,

00:08that S, the premise of a new and innovative molecular strategy

00:11that could change the future of cancer treatment.

00:14A team at the University of Santiago de Compostela,

00:18led by Professor Miguel,

00:19has made a significant breakthrough in the battle against this disease.

00:22For decades, the great challenge has been how to direct treatments

00:25straight to cancer cells without harming healthy tissue.

00:28Now, these researchers have developed a system

00:31that activates with unprecedented precision.

00:35The heart of this system is a small peptide molecule called BTMA-1

00:39under normal physiological conditions.

00:42These molecules self-organize into stable structures called helical fibers.

00:47Think of them as tiny, complex spools of thread that form on their own.

00:51The fascinating part is that these fibers are essentially inactive precursors.

00:56They are designed to store their biological function,

00:59waiting for the right moment and the correct signal.

01:02They don't interact with just anything, they simply wait.

01:06That signal arrives in the form of specific metal ions, such as cobalt,

01:10which can be present in the environment of cancer cells.

01:13When the BTMA-1 fibers detect these ions,

01:16they undergo a fascinating transformation.

01:18They disassemble and, in doing so, release biologically active peptidic helicot.

01:24These new helicots have a crucial function.

01:27They are capable of recognizing and interacting with a specific DNA confirmation,

01:32known as three-way DNA, which is associated with cancer.

01:36This controlled conversion is the key point of the breakthrough.

01:39It allows the functional material to activate only when stimulated by its environment,

01:43instead of being active all the time and potentially causing side effects.

01:48This behavior of storing its biological function until it's needed is a revolutionary concept.

01:54Although researchers acknowledge that clinical application is still far off,

01:58this research is foundational.

02:00It lays the groundwork for a new molecular strategy

02:03that is both adaptable and sensitive to its environment.

02:06In the future, this could allow for precise spatiotemporal control

02:11of the interactions between molecules and DNA,

02:13leading to much more specific and effective anti-cancer therapies.

02:18We are approaching a future where treatments could be far more precise,

02:21opening up new possibilities at the intersection of biological chemistry

02:24and molecular materials.
