Abstract
INTRODUCTION Androgenetic alopecia (AGA) is a prevalent, multifactorial form of hair loss involving complex aetiological factors, such as altered androgen regulation and energy metabolism. Existing treatments offer limited success, thus highlighting the need for advanced, personalised therapeutic strategies. This study focuses on correlating the genetic mechanisms of AGA with molecular targets involved in the response to current treatment modalities. METHODS An anonymised database including 26,607 patients was subjected to analysis. The dataset included information on patients' genotypes in 26 single nucleotide polymorphisms (SNPs), specifically, and diagnosed AGA grades, representing a broad range of ethnic backgrounds. RESULTS In our sample, 64.6% of males and 35.4% of females were diagnosed with female pattern hair loss. This distribution aligns well with prior studies, thus validating the representativeness of our dataset. AGA grading was classified using the Hamilton-Norwood and Ludwig scales, although no association was found to the grade of the disease. SNP association analysis revealed eight SNPs, namely rs13283456 (PTGES2), rs523349 (SRD5A2), rs1800012 (COL1A1), rs4343 (ACE), rs10782665 (PTGFR), rs533116 (PTGDR2), rs12724719 (CRABP2) and rs545659 (PTGDR2), to be statistically significant with a p-value below 0.05. CONCLUSIONS The study establishes a preliminary association between eight specific SNPs and AGA. These genetic markers offer insights into the variability of therapeutic responses, thus underlining the importance of personalised treatment approaches. Our findings show the potential for more targeted research to understand these SNPs' and further roles in AGA pathophysiology and in modulating treatment response.

Abstract
AIMS We aimed to develop a gene signature that predicts the occurrence of postmenopausal osteoporosis (PMOP) by studying its genetic mechanism. METHODS Five datasets were obtained from the Gene Expression Omnibus database. Unsupervised consensus cluster analysis was used to determine new PMOP subtypes. To determine the central genes and the core modules related to PMOP, the weighted gene co-expression network analysis (WCGNA) was applied. Gene Ontology enrichment analysis was used to explore the biological processes underlying key genes. Logistic regression univariate analysis was used to screen for statistically significant variables. Two algorithms were used to select important PMOP-related genes. A logistic regression model was used to construct the PMOP-related gene profile. The receiver operating characteristic area under the curve, Harrell's concordance index, a calibration chart, and decision curve analysis were used to characterize PMOP-related genes. Then, quantitative real-time polymerase chain reaction (qRT-PCR) was used to verify the expression of the PMOP-related genes in the gene signature. RESULTS We identified three PMOP-related subtypes and four core modules. The muscle system process, muscle contraction, and actin filament-based movement were more active in the hub genes. We obtained five feature genes related to PMOP. Our analysis verified that the gene signature had good predictive power and applicability. The outcomes of the GSE56815 cohort were found to be consistent with the results of the earlier studies. qRT-PCR results showed that RAB2A and FYCO1 were amplified in clinical samples. CONCLUSION The PMOP-related gene signature we developed and verified can accurately predict the risk of PMOP in patients. These results can elucidate the molecular mechanism of RAB2A and FYCO1 underlying PMOP, and yield new and improved treatment strategies, ultimately helping PMOP monitoring.Cite this article: Bone Joint Res 2022;11(8):548-560.

Abstract
Bone is a dynamic organ maintained by tightly regulated mechanisms. With old age, bone homeostasis, which is maintained by an intricate balance between bone formation and bone resorption, undergoes deregulation. Oxidative stress-induced DNA damage, cellular apoptosis, and cellular senescence are all responsible for this tissue dysfunction and the imbalance in the bone homeostasis. These cellular mechanisms have become a target for therapeutics to treat age-related osteoporosis. Genetic mouse models have shown the importance of senescent cell clearance in alleviating age-related osteoporosis. Furthermore, we and others have shown that targeting cellular senescence pharmacologically was an effective tool to alleviate age- and radiation-induced osteoporosis. Senescent cells also have an altered secretome known as the senescence associated secretory phenotype (SASP), which may have autocrine, paracrine, or endocrine function. The current review discusses the current and potential pathways which lead to a senescence profile in an aged skeleton and how bone homeostasis is affected during age-related osteoporosis. The review has also discussed existing therapeutics for the treatment of osteoporosis and rationalizes for novel therapeutic options based on cellular senescence and the SASP as an underlying pathogenesis of an aging bone.

The Association of Multiple Gene Variants with Ageing Skeletal Muscle Phenotypes in Elderly Women. Genes (Basel) 2020; 11:genes11121459. [PMID: 33291384 PMCID: PMC7762041 DOI: 10.3390/genes11121459] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 11/24/2020] [Accepted: 12/03/2020] [Indexed: 12/20/2022] Open
Abstract
There is a scarcity of studies that have investigated the role of multiple single nucleotide polymorphisms (SNPs) on a range of muscle phenotypes in an elderly population. The present study investigated the possible association of 24 SNPs with skeletal muscle phenotypes in 307 elderly Caucasian women (aged 60–91 years, 66.3 ± 11.3 kg). Skeletal muscle phenotypes included biceps brachii thickness, vastus lateralis cross-sectional areas, maximal hand grip strength, isometric knee extension and elbow flexion torque. Genotyping for 24 SNPs, chosen on their skeletal muscle structural or functional links, was conducted on DNA extracted from blood or saliva. Of the 24 SNPs, 10 were associated with at least one skeletal muscle phenotype. HIF1A rs11549465 was associated with three skeletal muscle phenotypes and PTK2 rs7460 and ACVR1B rs10783485 were each associated with two phenotypes. PTK2 rs7843014, COL1A1 rs1800012, CNTF rs1800169, NOS3 rs1799983, MSTN rs1805086, TRHR rs7832552 and FTO rs9939609 were each associated with one. Elderly women possessing favourable genotypes were 3.6–13.2% stronger and had 4.6–14.7% larger muscle than those with less favourable genotypes. These associations, together with future work involving a broader range of SNPs, may help identify individuals at particular risk of an age-associated loss of independence.

Association of the Sp1 binding site and -1997 promoter variations in COL1A1 with osteoporosis risk: The application of meta-analysis and bioinformatics approaches offers a new perspective for future research. MUTATION RESEARCH. REVIEWS IN MUTATION RESEARCH 2020; 786:108339. [PMID: 33339581 DOI: 10.1016/j.mrrev.2020.108339] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/22/2019] [Revised: 08/11/2020] [Accepted: 10/06/2020] [Indexed: 12/21/2022]
Abstract
As a complex disease, osteoporosis is influenced by several genetic markers. Many studies have examined the link between the Sp1 binding site +1245 G > T (rs1800012) and -1997 G > T (rs1107946) variations in the COL1A1 gene with osteoporosis risk. However, the findings of these studies have been contradictory; therefore, we performed a meta-analysis to aggregate additional information and obtain increased statistical power to more efficiently estimate this correlation. A meta-analysis was conducted with studies published between 1991-2020 that were identified by a systematic electronic search of the Scopus and Clarivate Analytics databases. Studies with bone mineral density (BMD) data and complete genotypes of the single-nucleotide variations (SNVs) for the overall and postmenopausal female population were included in this meta-analysis and analyzed using the R metaphor package. A relationship between rs1800012 and significantly decreased BMD values at the lumbar spine and femoral neck was found in individuals carrying the "ss" versus the "SS" genotype in the overall population according to a random effects model (p < 0.0001). Similar results were also found in the postmenopausal female population (p = 0.003 and 0.0002, respectively). Such findings might be an indication of increased osteoporosis risk in both studied groups in individuals with the "ss" genotype. Although no association was identified between the -1997 G > T and low BMD in the overall population, those individuals with the "GT" genotype showed a higher level of BMD than those with "GG" in the subgroup analysis (p = 0.007). To determine which transcription factor (TF) might bind to the -1997 G > T in COL1A1, 45 TFs were identified based on bioinformatics predictions. According to the GSE35958 microarray dataset, 16 of 45 TFs showed differential expression profiles in osteoporotic human mesenchymal stem cells relative to normal samples from elderly donors. By identifying candidate TFs for the -1997 G > T site, our study offers a new perspective for future research.

Abstract
Objective: The aim of this study was to analyze the genetic association of five ESR1 single nucleotide polymorphisms (SNPs) (rs3020331, rs851982, rs1999805, rs2234693, rs3020404), four COL1A1 SNPs (rs1800012, rs2075555, rs2412298, rs1107946), and two SNPs on the CCDC170 gene (rs9479055, rs4870044) with distal radius fracture (DRF) in a group of postmenopausal Mexican women.Methods: A case-control study was conducted. Cases (n = 182) were women above the age of 38 years with low-energy DRF, and controls (n = 201) were women without. Analysis was done through real-time polymerase chain reaction. Frequencies and Hardy-Weinberg equilibrium were calculated. A multivariate analysis including bone mass index, age, menarche, and menopause as covariables was carried out. Finally, haplotype and linkage disequilibrium (LD) analyses were performed.Results: COL1A1 rs1107946 was strongly associated with DRF. Both CCDC170 SNPs showed strong association with DRF. For the ESR1 gene, four SNPs (rs2234693, 3020404, rs3020331, and rs851982) showed very strong association with DRF. Additionally, the region between the latter two showed strong LD.Conclusions: A strong association of DRF with variants in these genes was found, including haplotypes and a region with strong LD on ESR1. The results suggest that these SNPs could be useful to detect the population at risk of presenting DRF among Mexican perimenopausal women.

Abstract
Introduction: Osteoporosis is characterized by a low bone mineral density. Genetic composition is one of the most influential factors in determining bone mineral density (BMD). There are few studies on genes associated with BMD in the Mexican population.
Objective: To investigate the association of eight single nucleotide polymorphisms (SNP) of JAG1, MEF2C and BDNF genes with BMD in women of Northern México.
Materials and methods: This study involved 124 unrelated Mexican women between 40 and 80 years old. BMD was determined by dual X-ray absorptiometry. Genotyping was performed using allelic discrimination by real time PCR. We analyzed the SNP of JAG1 (rs6514116, rs2273061, rs2235811 and rs6040061), MEF2C (rs1366594, rs12521522 and rs11951031), and BDNF (rs6265) and the data using linear regression.
Results: The JAG1 SNP rs2235811 was associated with the BMD of the total body under the dominant inheritance model (p=0,024). Although the other SNPs were not associated with BMD in any of the inheritance models studied, a trend was observed.
Conclusion: Our results suggest that the SNP rs2235811 in the JAG1 gene might contribute to the variation in BMD in women from northern México.

Abstract
To identify genetic variants influencing bone mineral density (BMD) in the Mexican-Mestizo population, we performed a GWAS for femoral neck (FN) and lumbar spine (LS) in Mexican-Mestizo postmenopausal women. In the discovery sample, 300,000 SNPs were genotyped in a cohort of 411 postmenopausal women and seven SNPs were analyzed in the replication cohort (n = 420). The combined results of a meta-analysis from the discovery and replication samples identified two loci, RMND1 (rs6904364, P = 2.77 × 10-4) and CCDC170 (rs17081341, P = 1.62 × 10-5), associated with FN BMD. We also compared our results with those of the Genetic Factors for Osteoporosis (GEFOS) Consortium meta-analysis. The comparison revealed two loci previously reported in the GEFOS meta-analysis: SOX6 (rs7128738) and PKDCC (rs11887431) associated with FN and LS BMD, respectively, in our study population. Interestingly, rs17081341 rare in Caucasians (minor allele frequency < 0.03) was found in high frequency in our population, which suggests that this association could be specific to non-Caucasian populations. In conclusion, the first pilot Mexican GWA study of BMD confirmed previously identified loci and also demonstrated the importance of studying variability in diverse populations and/or specific populations.

Abstract
Nowadays, multifactorial nature of osteoporosis does not raise any doubts. Besides, it should be noted that about 90% disease cases are determined genetically. In 1990-s a number of candidate genes mutations were established which increase the risk of osteoporosis development. VDR, ESR1, ESR2, COLIA1, PTH, CT, CTR, BGP, AR, GCCR, TGFB1, IL-6, IGF1, IL-1ra, OPG were considered to be this kind of genes. New genetic analysis technologies (GWAS, etc.) gave the opportunity to expand our conception about multi genomic pathogenesis of osteoporosis and to point out a new group of genes candidate - a canonical Wnt-signaling pathway genes (CTNNB1, SOST, FOXC2, FOXL1, LRP4, LRP5, WNT1, WNT3, WNT16, DKK1, AXIN1, JAG1, etc.). Extreme importance of canonical Wnt-signaling pathway and genes given above in skeleton formation and its strength necessitate the need for further scientific research and opens perspective to improve osteoporosis diagnostics, treatment and prognosis.

Abstract
BACKGROUND AND AIMS Osteoporosis leads to high fracture risk and evidence suggests that genetic factors play an important role in this disease. The aim was to evaluate the association of two polymorphisms (-1997G/T, +1245G/T) in the collagen type1 alpha 1 gene (COL1A1) with fracture or with low bone mineral density (BMD) at the hip in postmenopausal Mexican women. METHODS BMD was determined by bone densitometry and the risk factors were collected with a questionnaire. Genotyping was performed by real-time PCR. RESULTS The polymorphisms were in Hardy-Weinberg equilibrium. The -1997G/+1245T haplotype showed, after adjustment for confounders, a fourfold increased risk of hip fracture [OR 4.32; p = 0.041 (95 % CI 1.07-17.43)]; while in the women with low BMD at the hip, the risk was increased threefold [OR 3.36; p = 0.022 (95 % CI 1.20-9.40)]. CONCLUSIONS The results support the association of COL1A1 gene polymorphisms with fracture and with low BMD at the hip in Mexican population.

Abstract
OBJECTIVE To conduct a meta-analysis of all association studies on two of the collagen 1 alpha 1 (COL1A1) gene polymorphisms, the -1997G/T (rs1107946) and the -1663indelT (rs2412298) polymorphisms and osteoporosis/BMD and fracture. METHODS PubMed/Medline and Web of Knowledge were searched for relevant association studies published in English. Pooled OR and its corresponding 95% CI or pooled MD and its corresponding 95% CI was calculated with the Cochrane Review Manager (Revman, version 5.2) using a random-effect or a fixed effect model. RESULTS No significant association between the -1997G/T polymorphism and Lumbar Spine (LS) and Femoral Neck (FN) BMD except for the Caucasian subpopulation wherein subjects with the T allele of the -1997G/T polymorphism was associated with significantly higher LS BMD. Our analysis did reveal that women, especially postmenopausal or perimenopausal women with the GG genotype, had significantly higher Total Hip (TH) BMD than those with the GT. Additionally, our meta-analysis did not show significant association between the -1997G/T polymorphism and risk of fracture, between the -1663indelT polymorphism and LS BMD in postmenopausal or perimenopausal women, or between the -1663indelT polymorphism and the risk of fracture. CONCLUSIONS Our results suggested the possibility of the COL1A1 -1997G/T and the -1663indelT polymorphisms individually playing very little role in osteoporosis and fracture, although more studies are needed especially for the analysis of association between these two polymorphisms and fracture. Haplotype studies may become one important future direction of study to further elucidate whether and how various COL1A1 polymorphisms affect bone health, osteoporosis and fracture.

Analysis of association of MEF2C, SOST and JAG1 genes with bone mineral density in Mexican-Mestizo postmenopausal women. BMC Musculoskelet Disord 2014; 15:400. [PMID: 25430630 PMCID: PMC4258010 DOI: 10.1186/1471-2474-15-400] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2014] [Accepted: 11/24/2014] [Indexed: 12/18/2022] Open
Abstract
Background Osteoporosis, a disease characterized by low bone mineral density (BMD), is an important health problem in Mexico. BMD is a highly heritable trait, with heritability estimates of 50-85%. Several candidate genes have been evaluated to identify those involved in BMD variation and the etiology of osteoporosis. This study investigated the possible association of single-nucleotide polymorphisms (SNPs) in the MEF2C, SOST and JAG1 genes with bone mineral density (BMD) variation in postmenopausal Mexican-Mestizo women. Methods Four hundred unrelated postmenopausal women were included in the study. Risk factors were recorded and BMD was measured in total hip, femoral neck and lumbar spine using dual-energy X-ray absorptiometry. In an initial stage, a total of twenty-five SNPs within or near SOST gene and seven SNPs in the JAG1 gene were genotyped using a GoldenGate assay. In a second stage, three MEF2C gene SNPs were also genotyped and SOST and JAG1 gene variants were validated. Real time PCR and TaqMan probes were used for genotyping. Results Linear regression analyses adjusted by age, body mass index and ancestry estimates, showed that five SNPs in the SOST gene were significantly associated with BMD in total hip and femoral neck but not lumbar spine. The lowest p value was 0.0012, well below the multiple–test significance threshold (p = 0.009), with mean effect size of -0.027 SD per risk allele. We did not find significant associations between BMD and MEF2C/JAG1 gene variants [rs1366594 “A” allele: β = 0.001 (95% CI -0.016; 0.017), P = 0.938; rs2273061 “G” allele: β = 0.007 (95% CI -0.007; 0.023), p = 0.409]. Conclusions SOST polymorphisms may contribute to total hip and femoral neck BMD variation in Mexican postmenopausal women. Together, these and prior findings suggest that this gene may contribute to BMD variation across populations of diverse ancestry.

Abstract
Osteoporosis is a complex disease characterized by low bone mineral density (BMD), which is determined by an interaction of genetics and environmental factors. Collagen type alpha 1 (COL1A) and JAGGED (JAG1) genes have been implicated in relation to BMD. The aim of this study was to investigate possible association among BMD and rs2273061 of JAG1, rs1107946 and rs1800012 of Col1A1 polymorphisms, as well as their haplotypes with BMD in postmenopausal Chinese women. A structured questionnaire for risk factors was recorded and BMD in lumbar spine and total hip was measured by dual-energy X-ray absorptiomety. Genomic DNA was obtained from 367 postmenopausal Chinese women. Genomic DNA was extracted from EDTA-preserved peripheral venous blood by phenol-chloroform extraction method and analyzed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). As a result, the rs1800012 polymorphism of COL1A1 showed an association with BMD of the lumbar spine under a dominant model. Besides, haplotype analysis of COL1A1 gene showed that G-G haplotype presented higher BMD in lumbar spine. No significant association between genotypes and alleles distributions of the rs1107946 polymorphism of COL1A1 and rs2273061 polymorphism of the JAG1 was found. In conclusion, our results suggest that the rs1800012 polymorphism of the COL1A1 and one haplotype were significantly associated with lumbar spine BMD variations in Chinese postmenopausal women.

WNT3A gene polymorphisms are associated with bone mineral density variation in postmenopausal mestizo women of an urban Mexican population: findings of a pathway-based high-density single nucleotide screening.

Abstract
Osteoporosis (OP) is a common skeletal disorder characterized by low bone mineral density (BMD) and is a common health problem in Mexico. To date, few genes affecting BMD variation in the Mexican population have been identified. The aim of this study was to investigate the association of single nucleotide polymorphisms (SNPs) located in genes of the Wnt pathway with BMD variation at various skeletal sites in a cohort of postmenopausal Mexican women. A total of 121 SNPs in or near 15 Wnt signaling pathway genes and 96 ancestry informative markers were genotyped in 425 postmenopausal women using the Illumina GoldenGate microarray SNP genotyping method. BMD was measured by dual-energy X-ray absorptiometry in total hip, femoral neck, Ward's triangle, and lumbar spine. Associations were tested by linear regression for quantitative traits adjusting for possible confounding factors. SNP rs752107 in WNT3A was strongly associated with decreased total hip BMD showing the highest significance under the recessive model (P = 0.00012). This SNP is predicted to disrupt a binding site for microRNA-149. In addition, a polymorphism of the Wnt antagonist DKK2 was associated with BMD in femoral neck under a recessive model (P = 0.009). Several LRP4, LRP5, and LRP6 gene variants showed site-specific associations with BMD. In conclusion, this is the first report associating Wnt pathway gene variants with BMD in the Mexican population.

Relation of the estrogen receptor and vitamin D receptor polymorphisms with bone mineral density in postmenopausal Mexican-mestizo women. Gene 2013; 537:10-4. [PMID: 24389498 DOI: 10.1016/j.gene.2013.12.054] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2013] [Revised: 12/17/2013] [Accepted: 12/21/2013] [Indexed: 12/25/2022]
Abstract
BACKGROUND Since osteoporosis is a complex disease characterized by low bone mineral density (BMD), which is determined by an interaction of genetics with metabolic and environmental factors, the aim of this study was to analyze the possible association among one polymorphism of VDR and two polymorphisms of ESR1; as well as their haplotypes with BMD in postmenopausal Mexican-mestizo women. METHODS We studied 742 postmenopausal Mexican-mestizo women. A structured questionnaire for risk factors was applied and BMD was measured in the lumbar spine and total hip by dual-energy X-ray absorptiometry. DNA was obtained from blood leukocytes. One polymorphism of VDR (rs11568820) and two of ESR1 (rs2234693 and rs9340799) were studied. Real-time PCR allelic discrimination was used for genotyping. The differences between the means of the BMDs according to genotype were analyzed with covariance. Hardy-Weinberg equilibrium was tested. Pairwise linkage disequilibrium between single nucleotide polymorphisms was calculated by direct correlation r(2); haplotype analysis was conducted. RESULTS Rs9340799 of ESR1 and one haplotype formed by the two polymorphisms of the ESR1 were significantly associated with FN-BMD variations. Moreover, analysis of the genotype of rs11568820 of VDR and the rs2234693 of ESR1 showed no significant differences with BMD variations. CONCLUSIONS Our results showed that rs9340799 and one haplotype of ESR1 were significantly associated with BMD only at the femoral neck and this association remained after adjusting for covariates.
