Özet
Aim: Nimodipine is used to prevent cerebrovascular-originated ischemic neurological deficits, yet its effects on nucleus pulposus
(NP) cells or annulus fibrosus (AF) cells weren’t studied. This study aimed to examine nimodipine’s effects on vitality and proliferation
of chondroadherin (CHAD), type II collagen (COL2A1), and hypoxia-inducible factor 1 alpha (HIF 1α) gene expression in human
primary NP/AF cells.
Material and Methods: NP/AF cell cultures obtained from 6 patients who underwent microdiscectomy were treated with 100
µMolar nimodipine and analyzed at 0, 24, and 48 h. Data were evaluated using one-way ANOVA and post-hoc Tukey HSD with 95%
confidence interval.
Results: We observed suppressed cell proliferation and increased necrosis in nimodipine-treated NP/AF cell cultures, especially
degenerated tissue. COL2A1 gene expression wasn’t detected in any experimental groups. CHAD and HIF 1α expression had timedependent decreases in control. CHAD and HIF 1α expression were found to decrease at 24h, but increased at 48h in degenerated
tissue. In nimodipine-applied intact tissues, CHAD expression was stable at 24h but 1.62 times higher than control at 48h. HIF 1α
levels were lower than control.
Conclusion: In nimodipine-treated degenerated AF/NP cultures, CHAD and HIF 1α expressions had time-dependent decreases.
However, after complete RT-PCR data evaluation, no correlation between nimodipine application and gene expression occurred.
