# Zebrafish study points to drug targets for spinal disc disease 2026-08-07T10:01:15+00:00 | Health & Science | Indian Opinion Desk Corroboration: 1 independent outlet A study using zebrafish has linked changes in gene activity to mineral build-up and hardening of spinal discs, a major feature of intervertebral disc degeneration. Researchers from the universities of Edinburgh and Bristol found that fish lacking one copy of a collagen IX-related gene developed spinal changes resembling human disc disease, including fused vertebrae and hardened tissue. The study, published in Communications Biology, identified disruptions in phosphate and fat metabolism, mTOR activity and vitamin A signalling. Bisphosphonates, osteoporosis medicines, blocked mineral build-up in the fish, while restricted feeding and drugs affecting fat metabolism reduced spinal fusions. The findings may support future non-surgical treatments, but they have not yet been proven in humans. Surgery remains the main long-term option for severe disc disease. ## Coverage - rediff.com Tags: back pain, gene activity, osteoporosis drugs, spinal discs, zebrafish research Canonical: https://indianopinion.org/zebrafish-study-points-to-drug-targets-for-spinal-disc-disease/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
