Abstract
Stigmasterol (STM), one of the main active components of Achyranthes bidentata, has been shown to effectively inhibit proinflammatory factors and matrix degradation in chondrocytes. However, the effect of STM on interleukin (IL)-1β-induced chondrocytes and its specific mechanism remain unclear. The purpose of the present study was to explore the effect and mechanism of sterol regulatory element binding transcription factor 2 (SREBF2) on IL-1β induced chondrocytes in the presence of STM. CCK-8 was used to detect the effect of STM on the cell viability of mouse chondrogenic cells (ATDC5). After ATDC5 cells were induced by IL-1β, the expression of SREBF2 in osteoarthritis cells was detected by RT-qPCR. The content of iron ion in the cells was detected by using an iron colorimetric assay kit. After further transfection of a SREBF2 overexpressing vector (Oe-SREBF2) or addition of a ferroptosis inhibitor, the expression levels of inflammation and matrix degradation-related proteins were detected via Western blotting. The levels of oxidative stress in cells were determined by using an ELISA kit. The results revealed that STM had no significant effect on the viability of ATDC5 cells. STM reduced IL-1β-induced ATDC5 cell damage and ferroptosis through SREBF2 and enhanced the inhibitory effect of ferroptosis inhibitors on IL-1β-induced ATDC5 cell injury. The present data suggest that STM attenuated chondrocyte injury induced by IL-1β by regulating ferroptosis via down-regulation of SREBF2, and may have potential as a novel therapeutic method for knee osteoarthritis.

SREBF1c and SREBF2 gene polymorphisms are associated with acute coronary syndrome and blood lipid levels in Mexican population. PLoS One 2019; 14:e0222017. [PMID: 31490983 PMCID: PMC6730878 DOI: 10.1371/journal.pone.0222017] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2019] [Accepted: 08/20/2019] [Indexed: 12/20/2022] Open
Abstract
Aim It has recently been reported that the sterol regulatory element-binding transcription factors (SREBF-1c, and -2) contribute to the variation in the plasma lipids levels, which have an important role in the atherosclerotic plaque development. The aim of the present study was to evaluate whether the SREBF1c and SREBF2 gene single nucleotide polymorphisms (SNPs) are associated with plasma lipids levels and ACS susceptibility in a case-control association study. Material and methods A case-control study was carried out in 625 patients with ACS (82% men and 18% women, with a mean age of 57.97 ± 10.5 years) and 700 healthy controls (66% men and 34% women, with a mean age of 54.37 ± 7.65 years). The sample size was calculated for a statistical power of 80%. We genotyped three SREBF1c (rs2297508, rs11656665 and rs11868035) and three SREBF2 (rs2267439, rs2267443, and rs2228314) gene polymorphisms by 5’ exonuclease TaqMan assays. The associations were evaluated by logistic regression under the co-dominant, dominant, recessive, over-dominant and additive inheritance models. The contribution of the genotypes on the plasma lipids levels was evaluated by Student’s t-test. Results Under different models, the SREBF1c rs2297508 (OR = 1.50, pCRes = 0.03), SREBF1c rs11656665 (OR = 1.35, pCDom = 0.02 and OR = 1.26, pCAdd = 0.02) and SREBF2 rs2228314 (OR = 1.78, pCRes = 0.03, OR = 1.27, pCAdd = 0.04) SNPs were associated with higher risk of ACS. On the other hand, the SREBF1c rs11868035 SNP was associated with lower risk of ACS (OR = 0.49, pCCo-dom = 0.001, OR = 0.66, pCDom = 0.003, OR = 0.57, PRes = 0.003 and OR = 0.71, pCAdd = 0.001). There was a statistically significant association of both SREBF1c rs11656665 and rs11868035 polymorphisms with plasma triglyceride levels. Conclusions In summary, our data suggest the association of the SREBF1c and SREBF2 SNPs with risk of developing ACS and with triglyceride levels in a Mexican population.

Abstract
Objective This study was performed to investigate the association between genetic variation in SMAD3 and hip osteoarthritis (OA) in a Chinese Han population. Methods The frequency of two single nucleotide polymorphisms of SMAD3, rs1470002 and rs12901499, was examined in 500 patients with hip OA and 1080 healthy controls in a Chinese Han population. Further analysis was performed according to sex and age. Results We detected statistically significant differences in the allele frequency and genotype between the hip OA and healthy control groups. The frequency of the GA+GG and GA genotypes of rs12901499 and the G variant were much higher in patients with hip OA than in healthy controls. This association was also present when the participants were stratified by sex and age. However, there was no significant association between the risk of hip OA and the presence of rs1470002 GA, AA, or GA+AA genotypes, even after sex- and age-stratified analysis. Conclusions The SMAD3 SNP rs12901499 GA genotype and G variant may increase the risk of hip OA in Chinese Han patients.

Association of SREBP2 gene polymorphisms with the risk of osteonecrosis of the femoral head relates to gene expression and lipid metabolism disorders. Mol Med Rep 2017; 16:7145-7153.

Abstract
Although lipid metabolism disorders have been recognized as a primary factor of osteonecrosis of the femoral head (ONFH), the molecular pathogenesis remains unclear. Sterol regulatory element‑binding protein 2 (SREBP2) specifically regulates cholesterol and fatty acid metabolism to maintain lipid homeostasis. To explore the roles of the SREBP2 gene in the development of ONFH, the authors analyzed the gene polymorphism and gene expression of three tag single nucleotide polymorphisms of the SREBP2 gene, the serum lipids levels, and their associations with ONFH development in 182 ONFH patients and 179 healthy controls. The results demonstrated that the stage IV proportions of ONFH patients carrying the rs2267439CT or CC genotype were significantly higher and lower than the stage III proportions of ONFH patients (P=0.039), respectively. The serum triglyceride, low‑density lipoprotein (LDL)‑c levels, and LDL‑C/high‑density lipoprotein (HDL)‑C ratio in the ONFH group were significantly increased compared to those in the control group (P=0.01, P=0.005, P=0.0001) while the HDL‑C level of ONFH group was remarkably lower than that of the control group (P=0.0001). Association analysis further revealed that the LDL‑c levels of the rs226744 GG and AG genotype carriers were statistically higher than that of the AA genotype carriers (P=0.039, P=0.05). These results demonstrated that the gene polymorphism of SREBP2 not only significantly associated with the clinical phenotypes of ONFH but also closely related to lipid metabolism disorder. The results indicated that SREBP2 gene polymorphism and function may play key roles in the development of ONFH.

Abstract
Objective To investigate associations between single polymorphisms (SNPs) rs1800469 and rs1982073 in the transforming growth factor-β1 gene (TGF-β1) and knee osteoarthritis (OA) susceptibility in a Chinese Han population. Methods TGF-β1 rs1800469 and rs1982073 were genotyped in patients with knee OA and age- and sex-matched OA-free controls from a Chinese Han population. The association was further analyzed according to gender and age. Results A total of 765 patients with knee OA and 780 controls were included. CT and CT + CC genotypes of rs1982073, and variant C, were associated with a significantly increased risk of knee OA. Stratification analysis showed that the association between the OA risk and rs1982073 CT heterozygotes compared with TT homozygotes was stronger in females and those aged >65 years. In contrast, CT, TT, and CT + TT genotypes of rs1800469 were not significantly associated with the risk of knee OA, even after further stratification analysis for gender and age. Conclusions The TGF-β1 rs1982073 T to C change and the variant C genotype may contribute to knee OA risk in the Chinese Han population.

Abstract
The aim of the study was to investigate the association between single nucleotide polymorphisms (SNPs), rs1861612 of delta/notch-like Epidermal Growth Factor (EGF)-related receptor (DNER) and rs1884190 in the Delta-like 1 ligand (DLL1) gene and type 2 diabetes mellitus (T2DM) susceptibility in a Chinese Han population. DNER rs1861612 and DLL1 rs1884190 polymorphisms were genotyped in patients with T2DM and age- and sex-matched T2DM-free controls from a Chinese Han population. A total of 298 patients with T2DM and 500 controls were enrolled in this study. We found that TC and TT genotypes of rs1861612 and variant T were associated with a significantly increased risk of T2DM. In contrast, the AG and AA genotypes of rs1884190 were not significantly associated with the risk of T2DM, even after further stratification analysis based on age or sex. Our results showed that DNER rs1861612 C to T change and variant T genotype may contribute to T2DM in a Chinese Han population.

Abstract
OBJECTIVE This study aims at investigating the relationship of SREBP-2 rs2228314 G>C polymorphism with the risk of nonalcoholic fatty liver disease (NAFLD) in a Han Chinese population. METHOD This case-control study was conducted at the First Affiliated Hospital of China Medical University. Three-hundred subjects who met the diagnostic criteria of NAFLD and had typical clinical and ultrasonographic findings were placed in the case group. There were 160 matched healthy controls in the control group. A common single nucleotide polymorphism (SNP) (rs2228314 G>C) in the SREBP-2 gene was tested. Genetic analyses were performed using genomic DNA extracted from peripheral blood leukocytes. Polymerase chain reaction-restriction fragment length polymorphism was applied to detect SNP. RESULTS Our results indicated that the GG genotype and G carrier (CG+GG) of rs2228314 G>C polymorphism in the SREBP-2 gene were strongly associated with susceptibility to NAFLD (both p<0.001). However, there was no significant difference in the frequency of G allele between NAFLD patients and healthy controls (p=0.328). Multivariate logistic regression analysis revealed that GG genotype, G carrier, body mass index, high-density lipoprotein cholesterol, total cholesterol, alanine aminotransferase, and γ-glutamyl-transferase might be associated with an increased risk of NAFLD (all p<0.05). CONCLUSION The results of this study provide evidence that the GG genotype and G carrier (CG+GG) of rs2228314 G>C polymorphism in the SREBP-2 gene may increase the risk of NAFLD.
