Insights
Genetic variations in Cathepsin S (CTSS) are linked to metabolic disorders like obesity and high cholesterol in the Chinese Han population. These findings offer insights into the genetic basis of metabolic diseases.
Area of Science:
- Genetics
- Metabolic Disorders
- Cardiovascular Disease
Background:
- Cathepsin S (CTSS) is implicated in cardiovascular disease and metabolic syndrome.
- Limited research exists on CTSS gene polymorphisms and metabolic disorders in Asian populations.
- Understanding genetic associations is crucial for metabolic disease pathogenesis.
Purpose of the Study:
- To investigate the association between CTSS gene polymorphisms and metabolic disorders.
- To analyze these associations in a Chinese Han population cohort.
Main Methods:
- A cohort of 1160 Chinese Han participants was studied.
- Genotyping was performed using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP).
- Statistical analyses were conducted to assess genotype-phenotype correlations and risks.
Main Results:
- CTSS polymorphism rs16827671 associated with Body Mass Index (BMI) and serum total cholesterol.
- Specific genotypes (CT of rs16827671, AG of rs11576175) and haplotypes (TA, CA) showed significant associations with hypercholesterolemia, hypertriglyceridemia, and borderline hypercholesterolemia.
- Individuals with CT genotype for rs16827671 had increased hypercholesterolemia risk; AG genotype for rs11576175 showed reduced risks for hypertriglyceridemia and borderline hypercholesterolemia.
Conclusions:
- Genetic polymorphisms in the CTSS gene are significantly associated with metabolic disorders in the Chinese Han population.
- These findings contribute to understanding the genetic underpinnings of metabolic disease development.
- Further research can explore CTSS's role in personalized medicine for metabolic health.
Abstract:
Cathepsin S (CTSS) played an important role in the etiology of cardiovascular disease and metabolic syndrome. Few studies had been reported on the association between the polymorphisms of CTSS and metabolic disorders in Asian population. Therefore we explored the association between the polymorphisms of CTSS and metabolic disorders in a Chinese Han population. The subjects were a Chinese Han cohort with 1160 participants, and the genotyping was performed with PCR-RFLP. Polymorphism rs16827671 was associated with BMI and serum total cholesterol (P=0.001; P=0.02, respectively). Subjects with CT genotype of rs16827671 had a higher risk of hypercholesterolemia (OR=1.64, 95% CI: 1.15-2.33, P=0.006) compared with TT genotype. Subjects with AG genotype of rs11576175 had lower risks of hypertriglyceridemia and borderline hypercholesterolemia (OR=0.52, 95% CI: 0.36-0.73, P=0.0001; OR=0.52, 95% CI: 0.35-0.77, P=0.001, respectively) compared with GG genotype. Compared with the haplotype TG, haplotype TA had a lower risk of hypertriglyceridemia and a higher risk of borderline hypercholesterolemia (OR=0.62, 95% CI: 0.44-0.88, P=0.002; OR=1.59, 95% CI: 1.10-2.31, P=0.008, respectively), and haplotype CA had a lower risk of hypercholesterolemia (OR=0.35, 95% CI: 0.18-0.68, P=0.002). In conclusion, we found that the genetic polymorphisms of CTSS were associated with metabolic disorders in a Chinese Han population, which would enrich the knowledge on genetic mechanisms of the pathogenesis of metabolic disorders.
