Summary
Genetic variations in Interleukin-1 beta (IL-1β) may increase the risk of lumbar disc herniation (LDH). Conversely, specific nitric oxide synthase (NOS) gene variations appear protective against LDH.
Area of Science:
- Genetics
- Molecular Biology
- Orthopedics
Background:
- Lumbar disc herniation (LDH) is a significant cause of low back pain.
- The genetic factors influencing LDH susceptibility are not fully understood.
- Cytokines and nitric oxide synthase (NOS) are implicated in inflammatory and degenerative processes.
Purpose of the Study:
- To investigate the association between single nucleotide polymorphisms (SNPs) in cytokine and NOS genes and the risk of LDH.
- To identify potential genetic markers for predicting LDH development.
Main Methods:
- A case-control study involving 179 participants (50 LDH patients, 129 controls).
- Genotyping of SNPs in IL-1α, IL-1β, TNF-α, eNOS, and iNOS genes.
- Comparison of SNP frequencies between LDH patients and healthy controls.
Main Results:
- The CC genotype and C allele of the IL-1β (+3953 T/C) SNP were significantly more prevalent in LDH patients.
- SNPs in eNOS (-768 T/C) and iNOS (22 G/A) were more frequent in the control group.
Conclusions:
- The IL-1β (+3953 T/C) SNP may contribute to the pathogenesis of LDH.
- eNOS (-786 T/C) and iNOS (22 G/A) SNPs might have a protective effect against LDH.
- Genotyping these SNPs could aid in identifying individuals at higher risk for LDH.

01:23Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
01:27Degenerative Disc Disease I: Introduction
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
03:18Non-LTR Retrotransposons
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
