Senolytic Therapy as a Preventive Strategy for Low Back Pain

Cell senescence drives inflammation and tissue breakdown and is a key hallmark of aging. Low back pain is strongly linked to age-related degeneration of spine tissues, and with an accumulation of senescent. Here we show that preventive administration of the senolytic agents o-vanillin and RG-7112 prevent the development of pain-related behaviour in young sparc-/- mice. Treated mice exhibit a reduction of senescence markers in the intervertebral discs, vertebral endplates, vertebral bone, and spinal cord, alongside a dampening of pro-inflammatory senescence-associated secretory factors in these tissues. This early senolytic intervention also preserves intervertebral disc volume and vertebral bone microarchitecture, indicating protection against structural degeneration of the spine. These findings demonstrate that targeting cellular senescence at an early stage can mitigate degenerative changes and pain, supporting senolytic therapy as a promising preventive strategy for musculoskeletal decline.

Senolytic Treatment for Low Back Pain.

Senescent cells (SnCs) accumulate due to aging and external cellular stress throughout the body. They adopt a senescence-associated secretory phenotype (SASP) and release inflammatory, and degenerative factors that actively contribute to age-related diseases such as low back pain (LBP). The senolytics, o-Vanillin and RG-7112, remove senescent human intervertebral (IVD) cells and reduce SASP release, but it is not known if they can treat LBP. sparc-/- mice, with LBP, were treated orally with o-Vanillin and RG-7112 as single or combination treatments. Treatment reduced LBP and SASP factor release and removed SnCs from the IVD and spinal cord. Treatment also lowered degeneration score in the IVDs, improved vertebral bone quality, and reduced the expression of pain markers in the spinal cord. The result indicates that RG-7112 and o-Vanillin with the combination treatment providing the strongest effect are potential disease-modifying drugs for LBP and other painful disorders where cell senescence is implicated.
