Summary: A brand-new preclinical study has demonstrated that spinal disc “zombie cell” can be cleared by two medicines, RG-7112, which could address the root cause of chronic low back pain. These senescent cell spore up as they age, become infected, and develop tissue-related injuries.
The drugs were most effective when combined with either drug when administered orally to mice, reducing swelling, relieving problems, and even restoring disc damage. By focusing on the source rather than just the symptoms, this innovative treatment may alter millions of people with chronic back pain.
Important Information
- Root Cause Targeted: Lumbar disc disease is fueled by zombie-like dormant cells.
- Dual Drug Influence: When combined, o-Vanillin and RG-7112 performed best.
- Oral Success: Medications delivered by lips reacted to damage done to hard-to-access lumbar discs.

Two drugs that target “zombie cell” have been shown to treat the underlying cause of chronic low back pain in a preliminary study led by McGill University experts. Millions of people are affected by the situation worldwide.
Recent solutions treat symptoms by causing pain or having surgery, but do not address the root cause.
Our findings are exciting because they suggest that we might be able to treat back pain in a completely different way by removing the cells that cause the pain rather than just masking it, according to senior author Lisbet Haglund, a professor in McGill’s Department of Surgery and co-director of the Orthopaedic Research Laboratory at the Montreal General Hospital ( MUHC).
The Montreal General Hospital, a division of the MUHC, is home to McGill’s Alan Edwards Center for Pain Research.
addressing problems at the supply
Dormant cells, also known as zombie cells, accumulate in the spinal discs as people get older or have disc damage. These aging tissues continue to live and cause irritation, pain, and harm to the back rather than dying off like normal tissues.
The analysis team administered two drugs, both an FDA-approved cancer drug and o-Vanillin, to mice to look for a possible option. They were administered individually as well as differently.
After eight weeks of treatment, the researchers discovered that the drugs may remove monster tissues from the spine, lessen pain and inflammation, and delayed or even change lumbar disc injury. Each of the medicines had a beneficial effect, but combining them produced the most of a positive impact.
The vertebral discs, which are difficult to access and present a significant challenge in treating back pain, were unfathomable to us when we received an dental treatment, said Haglund. The big question is then whether these medications may cause the same effects in people.
Unbeknown possibility of a normal compound
Importantly, o-Vanillin was almost by accident to be included in the study even though it wasn’t initially intended to. Haglund explained that her staff decided to add the turmeric-based substance to their tests to see if it might be successful in this circumstance. The compound is known for its anti-inflammatory qualities.
The findings provide some of the initial proof that o-Vanillin may eradicate monster cells. Although not used to treat back pain, RG-7112 analogs have been shown to do this in studies into osteoarthritis and cancer.
Haglund’s team will work toward improving o-Vanillin’s structure to make it stay in the body more and become even more powerful. They think that these medications have the power to treat dormant cell-driven arthritis and osteoporosis, two additional aging conditions.

Abstract
Senolytic therapy for back problems
Senescent cells ( SnCs ) accumulate throughout the body as a result of aging and external cellular stress. They adopt a senescence-associated secretory phenotype ( SASP) and start releasing inflammatory and degenerative factors that actively contribute to aging conditions like low back pain ( LBP).
SnCs are removed from human intervertebral discs ( IVDs ) by the senolytics  , o-vanillin, and RG-7112, and SASP release is reduced, but it is not known whether they can treat LBP. Verbally administered with RG-7112, o-vanillin, and sparc/#, animals with LBP received either as single or combined treatments.
Treatment removed SnCs from the IVD and spinal cord while lowering LBP and SASP issue transfer.
Additionally, treatment reduced the number of IVDs with degeneration, improved the quality of the spinal bones, and decreased the cervical cord’s pain markers.
Our research jointly suggests that RG-7112 and o-vanillin could be effective treatment for LBP and other agonizing cell senescences.
