CML is kind of the predominant molecule

0:02

that that gets formed in this

0:04

extracellular matrix that's driving

0:06

aging and nothing breaks it down. So,

0:08

these scientists set out to try and

0:10

create an enzyme. An enzyme is a protein

0:11

that breaks something down that can

0:13

break down CML. And so, these guys kind

0:15

of went out and they took the target,

0:17

which is CML and tried to figure out,

0:19

okay, how do we actually degrade CML,

0:22

clear that extracellular matrix and

0:24

reverse aging. They started to test it

0:26

on the proteins that we would find in

0:29

our body, casein, collagen, retinal

0:32

proteins, which are in your eye,

0:34

hemoglobin, and they were able to get

0:36

rid of 52 to 97%

0:39

of the CML. Just degrade it away.

0:42

And then they they found several sites

0:45

where they were able to degrade over 90%

0:47

and then they took actual human skin

0:49

from elderly patients that had donated

0:52

their skin and they put this enzyme onto

0:56

that skin and they were able to

0:58

eliminate 55% of the CML on the skin,

1:01

basically reverse the skin's age down to

1:04

the age of a 31-year-old. This is from

1:06

greater than 70-year-old patients just

1:08

by putting this enzyme on the skin. And

1:10

so, it's kind of a groundbreaking

1:12

demonstration of combination of

1:14

AlphaFold, what's called directed

1:16

evolution, where you change the order of

1:19

the DNA that changes the structure of

1:20

the protein to test different proteins,

1:22

do high-throughput screening, and

1:25

ultimately make a novel protein that

1:27

doesn't exist in nature today that can

1:28

do something pretty profound for human

1:30

health.

1:30

>> It will be a trillion-dollar market.

1:33

>> [laughter]

1:33

>> Yeah. You can create a cream

1:35

>> if you could put this enzyme literally

1:36

on your skin and have it absorbed in

1:38

>> cream.

1:39

>> Yeah.

1:39

>> Game over.

1:40

>> Unbelievable.

1:40

>> That alone is $2 trillion.

Interactive Summary

Scientists have developed a novel enzyme designed to break down CML, a molecule associated with aging in the extracellular matrix. By utilizing advanced techniques like AlphaFold and directed evolution, researchers created a protein that successfully degraded CML in human tissue samples, effectively rejuvenating skin from elderly donors to a biological age of 31. This breakthrough suggests potential for future anti-aging skin treatments.
