ABSTRACT
OBJECTIVE:
To investigate the association of FasL-844T/C gene polymorphism with the magnetic resonance imaging (MRI) findings and FasL expression in the nucleus pulposus of degenerative lumbar intervertebral discs.METHODS:
Lumbar MRI data, venous blood and nucleus pulposus were collected from 105 patients with lumbar disc herniation. The genotypes of FasL-844T/C gene of the patients were determined using matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Immunohistochemistry was used to detect the expression of FasL in the nucleus pulposus of the degenerative lumbar intervertebral discs.RESULTS:
Compared with CC genotype, TT genotype of FasL-844T/C gene was associated with a significantly increased score of lumbar disc degeneration (P=0.003) as observed in MRI scan. FasL expression in the nucleus pulposus differed significantly between patients of FASL-844CC genotype and those of FASL-844TT genotype (P=0.048), but not between those of FASL-844CC and FASL-844CT genotypes (P=0.264). No significant association was found between MRI findings and FasL expression in the nucleus pulposus of the lumbar intervertebral discs.CONCLUSION:
FasL-844T/C gene polymorphism is correlated with the expression of FasL in the nucleus pulposus of the intervertebral disc in patients with lumbar disc herniation. MRI findings of the lumbar intervertebral discs do not correlate with the expression of FasL in the nucleus pulposus of the intervertebral discs.
