Yeah, inter-species gene splicing. What could possibly go wrong?

It's like Jurassic Park, but with people.

Imagine if you could splice into that gene, where human teeth never stop growing. That would solve alot of problems.


I mean, chocolate flavored log, I might could naw on two or three a night

And we'd be gnawing on a log constantly.

This does look like legit research, though it remains to be seen whether a practical therapy can be developed.

The USAG-1 molecule is a key target for tooth regeneration therapies:

What is USAG-1?
USAG-1 is a molecule that regulates the number of teeth that develop in healthy adults. It prevents potential tooth germs from forming into full teeth.

How USAG-1 is targeted for tooth regeneration?
A neutralizing antibody that suppresses USAG-1 has been shown to restore missing teeth and alveolar bone in animal models.

Why USAG-1 is a target for tooth regeneration
Regenerating teeth with an antibody preparation could be a curative treatment, unlike dentures and dental implants.

Human trials began in September 2024 at Kyoto University Hospital in Japan.

Abstract

Uterine sensitization-associated gene-1 (USAG-1) deficiency leads to enhanced bone morphogenetic protein (BMP) signaling, leading to supernumerary teeth formation. Furthermore, antibodies interfering with binding of USAG-1 to BMP, but not lipoprotein receptor-related protein 5/6 (LRP5/6), accelerate tooth development. Since USAG-1 inhibits Wnt and BMP signals, the essential factors for tooth development, via direct binding to BMP and Wnt coreceptor LRP5/6, we hypothesized that USAG-1 plays key regulatory roles in suppressing tooth development. However, the involvement of USAG-1 in various types of congenital tooth agenesis remains unknown. Here, we show that blocking USAG-1 function through USAG-1 knockout or anti-USAG-1 antibody administration relieves congenital tooth agenesis caused by various genetic abnormalities in mice. Our results demonstrate that USAG-1 controls the number of teeth by inhibiting development of potential tooth germs in wild-type or mutant mice missing teeth. Anti-USAG-1 antibody administration is, therefore, a promising approach for tooth regeneration therapy.

No gene splicing. They're administering an antibody to counteract a naturally occurring protein. First test animals, now humans.

My worry would be teeth growing in unnatural locations. In a sinus cavity or some other inconvenient place.

^Well, in theory they wouldn't grow anywhere they haven't grown before.
