Reversing osteoporosis may someday be as simple as taking a tablet.
A crew of FIU drug growth scientists discovered a doable new option to counteract the consequences of the illness that turns bones into honeycomb-like buildings — so fragile even a cough could cause a fracture or break. The invention, lately revealed in Communications Biology, is step one towards cheaper, efficient, easy-to-take therapies for osteoporosis and different illnesses related to bone loss.
Presently out there medication solely cease bone loss and require costly day by day injections. Researchers from FIU’s Herbert Wertheim Faculty of Drugs — together with a collaborative crew from the Nationwide Middle for Advancing Translational Sciences (NCATS), a part of the Nationwide Institutes of Well being (NIH), and College of Arkansas for Medical Sciences — recognized a way that may be taken orally and helps bone-producing cells make extra bone.
“Our experiments within the lab confirmed small molecule activators delivered orally enhance bone density, an thrilling discovery that might result in a brand new remedy for osteoporosis,” mentioned examine writer Alexander Agoulnik, FIU professor and interim chair of the Division of Human and Molecular Genetics.
Bones are basically at all times beneath renovation. Cells break down and reform bone across the clock. Bone-making cells construct bone tissue, whereas bone-eating ones reabsorb it to maintain bones from getting too huge or cumbersome. It’s a fragile dance. And it goes awry throughout osteoporosis when bone-making cells decelerate and bone-eating cells hold at a gradual tempo.
To assist bone-producing cells sustain, the researchers centered on a selected goal. A hormone receptor — relaxin household peptide receptor 2 (RXFP2), identified to play a job within the formation of reproductive organs.
“After we first screened sufferers with cryptorchidism, or undescended testes, we present in a few of them this receptor was mutated,” Agoulnik mentioned. “Then, colleagues from the College of Padova, Italy, surprisingly found that a good portion of those males additionally occurred to have osteoporosis.”
The crew suspected the receptor additionally had one thing to do with bone growth. Additional analysis revealed it did.
The crew first needed to pinpoint the precise chemical compound to activate the receptor. The NCATS crew used robots to display screen for small molecules, amongst greater than 80,000 totally different compounds. Chemists then examined tons of extra variations till they discovered the precise match. It was like a key becoming a lock. After they examined it on mouse fashions within the lab, they noticed an enchancment in bone density.
“I selected FIU as a result of FIU has a really numerous worldwide neighborhood.”

“This opens up a brand new space of examine to permit for scientific utility to forestall or reverse osteoporosis,” mentioned Maria Esteban Lopez, who labored with Agoulnik on this analysis as an FIU biomedical sciences Ph.D. candidate. “This was an thrilling alternative. I used to be in a position to work with phenomenal scientists throughout numerous establishments and see how the influence of our work may result in significant therapeutic breakthroughs.”
Researchers know a brand new remedy may very well be life-changing for tens of millions of individuals, and stay up for the following section of analysis.
“With out collaboration, we might by no means have discovered the hyperlink between our genes and bone growth. And the collaboration with NIH was essential as a result of they’re the very best within the area to search for the precise compounds,” Agoulnik mentioned. “The principle ingredient for fulfillment in science is collaboration.”
This analysis was supported by the Nationwide Institute of Arthritis and Musculoskeletal and Pores and skin Illnesses (NIAMS) on the NIH.
