van den Driest L, Kelly P, Marshall A, Johnson CH, Lasky-Su J, Lannigan A, Rattray Z, Rattray NJ. A gap analysis of UK biobank publications reveals SNPs associated with intrinsic subtypes of breast cancer. Comput Struct Biotechnol J 2024; 23:2200-2210. [PMID: 38817965 PMCID: PMC11137368 DOI: 10.1016/j.csbj.2024.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Revised: 05/01/2024] [Accepted: 05/02/2024] [Indexed: 06/01/2024] Open
Abstract
Breast cancer is a multifaceted disease and a leading cause of cancer morbidity and mortality in females across the globe. In 2020 alone, 2.3 million women were diagnosed and 685,000 died of breast cancer worldwide. With the number of diagnoses projected to increase to 3 million per year by 2040 it is essential that new methods of detection and disease stratification are sought to decrease this global cancer burden. Although significant improvements have been made in breast cancer diagnosis and treatment, the prognosis of breast cancer remains poor in some patient groups (i.e. triple negative breast cancer), necessitating research into better patient stratification, diagnosis and drug discovery. The UK Biobank, a comprehensive biomedical and epidemiological database with a wide variety of multiomics data (genomics, proteomics, metabolomics) offers huge potential to uncover groundbreaking discoveries in breast cancer research leading to improved patient stratification. Combining genomic, proteomic, and metabolic profiles of breast cancer in combination with histological classification, can aid treatment decisions through accurate diagnosis and prognosis prediction of tumor behaviour. Here, we systematically reviewed PubMed publications reporting the analysis of UK Biobank data in breast cancer research. Our analysis of UK Biobank studies in the past five years identified 125 publications, of which 76 focussed on genomic data analysis. Interestingly, only two studies reported the analysis of metabolomics and proteomics data, with none performing multiomics analysis of breast cancer. A meta-analysis of the 76 publications identified 2870 genetic variants associated with breast cancer across 445 genes. Subtype analysis revealed differential genetic alteration in 13 of the 445 genes and the identification of 59 well-established breast cancer genes. in differential pathways. Pathway interaction analyses illuminated their involvement in general cancer biomolecular pathways (e.g. DNA damage repair, Gene expression). While our meta-analysis only measured genetic differences in breast cancer due to current usage of UK Biobank data, minimal multi-omics analyses have been performed and the potential for harnessing multi-omics strategies within the UK Biobank cohort holds promise for unravelling the biological signatures of distinct breast cancer subtypes further in the future.

Abstract
OBJECTIVES The aim of this study was to (1) replicate previously identified genetic variants significantly associated with pelvic organ prolapse and (2) identify new genetic variants associated with pelvic organ prolapse using a genome-wide association study. METHODS Using our institution's database linking genetic and clinical data, we identified 1,329 women of European ancestry with an International Classification of Diseases, Ninth Revision (ICD-9)/ICD-10 code for prolapse, 767 of whom also had Current Procedural Terminology (CPT)/ICD-9/ICD-10 procedure codes for prolapse surgery, and 16,383 women of European ancestry older than 40 years without a prolapse diagnosis code as controls. Patients were genotyped using the Illumina HumanCoreExome chip and imputed to the Haplotype Reference Consortium. We tested 20 million single nucleotide polymorphisms (SNPs) for association with pelvic organ prolapse adjusting for relatedness, age, chip version, and 4 principal components. We compared our results with 18 previously identified genome-wide significant SNPs from the UK Biobank, Commun Biol (2020;3:129), and Obstet Gynecol (2011;118:1345-1353). RESULTS No variants achieved genome-wide significance (P = 5 × 10-8). However, we replicated 4 SNPs with biologic plausibility at nominal significance (P ≤ 0.05): rs12325192 (P = 0.002), rs9306894 (P = 0.05), rs1920568 (P = 0.034), and rs1247943 (P = 0.041), which were all intergenic and nearest the genes SALL1, GDF7, TBX5, and TBX5, respectively. CONCLUSIONS Our replication of 4 biologically plausible previously reported SNPs provides further evidence for a genetic contribution to prolapse, specifically that rs12325192, rs9306894, rs1920568, and rs1247943 may contribute to susceptibility for prolapse. These and previously reported associations that have not yet been replicated should be further explored in larger, more diverse cohorts, perhaps through meta-analysis.

Abstract
Objectives The aim of the study was to describe time intervals between pessary maintenance visits in racially diverse women receiving care in a U.S. epicenter of the COVID-19 pandemic. We secondarily aimed to determine whether time interval between pessary changes is associated with adverse outcomes and to identify factors associated with adverse pessary outcomes. Methods We performed a retrospective study of women undergoing pessary care after the COVID-19 pandemic began. Time between the most recent visit before the pandemic and first visit after the pandemic began was recorded. Pessary care data were collected from the latter visit, including vaginal bleeding, vaginal discharge, and erosion. Patient-reported symptoms and demographics were also recorded. The relationship between time interval between pessary visits and adverse outcomes as well as between adverse outcomes and demographic data was assessed. Results We identified 104 women undergoing pessary care, of which 35.6% were Hispanic and 32.7% were Black and 26.2% ± 10.5% lived in poverty. The median time to in-person visit was 4.5 months (interquartile range, 3.7–5.3 months). Seven women (8.7%) had vaginal bleeding, 15 (14.6%) had vaginal discharge, and 7 (6.8%) had erosions. There was no significant association between time interval between pessary visits and adverse outcomes or between adverse outcomes and patient characteristics (all P > 0.05). Conclusions Longer duration of time between pessary maintenance visits is not associated with increased adverse outcomes in this group of racially diverse women. Extended intervals between pessary visits can be considered to minimize risk and maintain patient safety during challenging circumstances, such as the COVID-19 pandemic.

Abstract
INTRODUCTION AND HYPOTHESIS Family and twin studies demonstrate that pelvic organ prolapse (POP) is heritable, but the genetic etiology is poorly understood. This review aimed to identify genetic loci and specific polymorphisms associated with POP, while assessing the strength, consistency, and risk of bias among reported associations. METHODS Updating an earlier systematic review, PubMed and HuGE Navigator as well as relevant conference abstracts were searched using genetic and phenotype keywords from 2015 to 2020. Screening and data extraction were performed in duplicate. Fixed and random effects meta-analyses were conducted using co-dominant models of inheritance. We assessed credibility of pooled associations using interim Venice criteria. RESULTS We screened 504 new abstracts and included 46 published and 7 unpublished studies. In pooled analyses we found significant associations for four polymorphisms: rs2228480 at the ESR1 gene (OR 0.67 95% CI 0.46-0.98, I2 = 0.0%, Venice rating BAB), rs12589592 at the FBLN5 gene (OR 1.46 95% CI 1.11-1.82, I2 = 36.3%, Venice rating BBB), rs484389 in the PGR gene (OR 0.61 95% CI 0.39-0.96, I2 = 32.4%, Venice rating CBB), and rs1800012 at the COL1A1 gene (OR 0.80 95% CI 0.66-0.96, I2 = 0.0%, Venice rating BAB). Further credible novel variants have also been recently identified in genome-wide association studies. CONCLUSION The genetic contributions to POP remain poorly understood. Several biologically plausible variants have been identified, but much work is required to establish the role of these genes in the pathogenesis of POP or to establish a role for genetic testing in clinical practice.

Family history and pelvic organ prolapse: a systematic review and meta-analysis. Int Urogynecol J 2020; 32:759-774.

Abstract
INTRODUCTION AND HYPOTHESIS Numerous analytic observational studies assess family history as a risk factor for POP and report a wide range of associations. This review aims to systematically evaluate the role of family history of POP in relation to POP risk and its recurrence. METHODS A review was performed of the PubMed/MEDLINE database with search criteria specifying family history, risk factors, POP, and their synonyms as title/abstract keywords, as well as MESH terms, up to March 2020. We aggregated evidence across studies with fixed effects (FE) and random effects (RE) meta-analysis. RESULTS Forty-three articles underwent full-text review. Eighteen independent studies evaluating the relationship between family history of POP and POP risk in 3639 POP cases and 10,912 controls were eligible for meta-analysis. Four studies evaluating family history and POP recurrence in 224 recurrent cases and 400 non-recurrent cases were eligible for inclusion into another meta-analyses. A positive family history of POP is on average associated with 2.3- to 2.7-fold increased risk for POP (RE OR = 2.64; 95% CI = 2.07, 3.35) as well as a 1.4-fold increased risk for POP recurrence (FE OR = 1.44; 95% CI = 1.00, 2.08). Meta-analysis estimates of POP risk varied by study design, definition of family history, and model adjustment status. We found evidence that publication bias and recall bias are a possibility. CONCLUSIONS Family history of POP is a risk factor for both POP presence and recurrence. However, reported magnitudes may be overestimates due to confounding, recall bias, and publication bias.

Polymorphism on chromosome 20p13 near the IDH3B gene is associated with uterine prolapse. Eur J Obstet Gynecol Reprod Biol 2020; 252:155-159.

Abstract
OBJECTIVES Previous studies have found evidence for a genetic basis for pelvic organ prolapse (POP), but no genetic studies have differentiated between types of POP. This study investigated whether genetic variants in six previously suggested candidate loci for POP modify the risk of uterine prolapse (UP). STUDY DESIGN One hundred patients, aged 30-55 years, who had undergone surgery due to total UP and 105 healthy controls were included in this study. After extracting the genomic DNA from peripheral blood, six single nucleotide polymorphisms (SNPs) previously identified for POP were genotyped, and association analysis was performed for contributing risk factors. RNA expression was determined from sacrouterine ligaments of patients and controls using quantitative reverse transcription polymerase chain reaction. RESULTS The dominant genotype model for the T allele for SNP rs6051098 at the chromosome 20p13 locus was significant, and this remained significant with the risk factor regression model (p=0.046; odds ratio 1.93, 95 % confidence interval 1.01-3.66). The isocitrate dehydrogenase 3 beta (IDH3B) gene was the only potential candidate gene in the 20p13 locus that was significantly upregulated in sacrouterine biopsies in women with UP compared with controls (p = 0.034). CONCLUSION To the best of the authors' knowledge, this is the first study to show that genetic risk factors contribute to UP, and suggested rs6051098 as the best candidate risk factor associated with UP. According to expression data in sacrouterine tissue, this study suggests that the IDH3B gene plays a role in the pathogenesis of UP.

Abstract
Pelvic organ prolapse (POP) is a downward descent of one or more of the pelvic organs, resulting in a protrusion of the vaginal wall and/or uterus. We performed a genome-wide association study of POP using data from Iceland and the UK Biobank, a total of 15,010 cases with hospital-based diagnosis code and 340,734 female controls, and found eight sequence variants at seven loci associating with POP (P < 5 × 10-8); seven common (minor allele frequency >5%) and one with minor allele frequency of 4.87%. Some of the variants associating with POP also associated with traits of similar pathophysiology. Of these, rs3820282, which may alter the estrogen-based regulation of WNT4, also associates with leiomyoma of uterus, gestational duration and endometriosis. Rs3791675 at EFEMP1, a gene involved in connective tissue homeostasis, also associates with hernias and carpal tunnel syndrome. Our results highlight the role of connective tissue metabolism and estrogen exposure in the etiology of POP.

Abstract
OBJECTIVE Pelvic organ prolapse (POP) is a common health issue that has a profound negative influence on women's quality of life. Genetic susceptibility to POP has been increasingly investigated. In this study, we assessed the single-nucleotide polymorphisms (SNPs) of six collagen-related genes (COL14A1, COL5A1, COL4A2, COL3A1, COL1A1, and COL18A1) and the genetic association with POP in Chinese women. METHODS We performed a candidate gene association study of case women (n = 48) with stage III and IV prolapse and control women (n = 48) without prolapse. A target region sequencing approach was used to identify the SNPs in collagen-related genes. The association between SNPs and POP was examined by Fisher exact tests for unadjusted model and logistic regression analysis adjusted for delivery and pregnancy. RESULTS There was a significant association between COL14A1 SNPs (rs4870723, rs2305600, and rs2305598; P = 0.013, 0.019, and 0.028, respectively), a COL5A1 SNP (rs3827852; P = 0.016), and COL4A2 SNPs (rs76425569, rs388222, and rs2281968; P = 0.049 for the three, and rs445348, P = 0.040) and POP, respectively. Although there was no significant association between the COL3A1 SNP and POP, there was a trend toward significance for COL14A1 SNP (rs2305603), COL4A2 SNP (rs74941798), two COL1A1 SNPs (rs2586488 and rs2249492) and three COL18A1 SNPs (rs1050351, rs56335679, and rs55690336), and POP. CONCLUSION We are the first to evaluate the relationship between COL14A1, COL5A1, and COL4A2 polymorphisms and POP, besides COL3A1, COL1A1, and COL18A1, which have been reported previously. We found several candidate SNPs that were significantly associated with prolapse in Chinese women. Our results provide new evidence for further investigation of the involvement of these potential genes in the etiology of POP.

Abstract
OBJECTIVE To investigate whether heavy load carrying, wearing a patuka, and body position at work are risk factors for uterine prolapse among Nepali women. METHODS Community-based case-control study of 448 women (170 cases of uterine prolapse; 278 controls) aged 18-60 years in Kaski district, Nepal was conducted. Women diagnosed with uterine prolapse were cases. Two controls were recruited for each case, frequency-matched by residential area and age. Multivariate logistic regression was used to investigate associations between outcome and exposures. RESULTS No association of heavy load carrying with uterine prolapse was observed; women who never used a patuka had lower odds of uterine prolapse (odds ratio = 0.18, 95% confidence interval = 0.05-0.71). Women working in a sitting position had higher odds than those working in a standing position (odds ratio = 2.94, 95% confidence interval = 1.74-4.96), as did women who mainly worked in a bending position (odds ratio = 2.45, 95% confidence interval = 1.12-5.34). Housewives were more prone to uterine prolapse than women engaged in farming (odds ratio = 2.13, 95% confidence interval = 1.31-3.47). CONCLUSION Using a patuka, occupation, and body position during work were all associated with uterine prolapse. No association was found with heavy load carrying, although that might be attributable to the cross-sectional nature of study recruitment.

Abstract
OBJECTIVE The aim of this study was to determine if there is a difference in Pelvic Floor Disability Index Questionnaire (PFDI-20) scores between black and white women seeking surgical management for pelvic organ prolapse (POP). METHODS A retrospective cohort study of 232 women who underwent pelvic reconstructive surgery with apical suspension for POP was performed. Demographic and clinical data were collected. All women completed the PFDI-20 and had a Pelvic Organ Prolapse Quantification examination at the initial consultation. Appropriate statistical tests were used to compare black and white women. Multivariable regression models adjusting for demographic and clinical variables were developed to determine the independent relationship between race and POP symptoms. RESULTS In our cohort, 174 (75%) were white and 58 (25%) were black. Compared with white women, black women had higher parity, body mass index, Charlson Comorbidity Index score, and anterior POP stage. White women had higher total PFDI-20 scores corresponding to higher scores on all symptom subscales. After controlling for potential confounders, white race and prior anti-incontinence surgery remained associated with higher total PFDI scores. Higher Urogenital Distress Inventory 6 scores were significantly associated with white race, prior anti-incontinence procedures, and increasing body mass index, whereas higher CRADI-8 scores were associated with prior anti-incontinence surgery and higher POP stages. CONCLUSIONS White women appeared to have more overall symptom bother from prolapse, as well as urinary symptoms, as compared with black women, when assessed by validated questionnaire tools in a cohort of patients who underwent prolapse surgery. Further research is required to determine if racial differences in symptoms translate to differences in outcomes.

Abstract
INTRODUCTION AND HYPOTHESIS We verified the presence of single nucleotide polymorphisms (SNP) rs2236479 of the collagen 18 (COL18A1) and rs2862296 of the lysyl oxidase-like 4 (LOXL-4) genes and the association with pelvic organ prolapse (POP) in Brazilian women and determined risk factors for POP development. METHODS We assessed 532 postmenopausal women divided into POP (stages III and IV) and control (stages 0 and I) groups by examination and peripheral blood sample collection. DNA sequences of interest were analyzed by real-time reverse-transcriptase polymerase chain reaction (RT-PCR). We used logistic regression models for the analyses, with p < 0.005 for significance. RESULTS The frequency of homozygous polymorphic alleles (AA) in COL18A1 and (GG) in LOXL-4 were similar in both groups (17.5% and 15.4% for COL18A1 and 18.9% and 20.6% for LOXL-4, respectively). There were no associations between those polymorphisms or other genotypes and POP. Multiple logistic regression analysis identified age [odds ratio (OR) = 1.10, confidence interval (CI) 95% = 1.07; 1.14), number of vaginal births (OR = 1.66, CI 95% = 1.36; 2.03), and family history (OR = 2.55 CI 95% = 1.43; 4.55) as independent risk factors for POP. CONCLUSION Our study suggests lack of association between DNA polymorphisms rs2236479 of COL18A1 and rs2862296 of LOXL-4 with advanced POP in this population.

Abstract
Pelvic organ prolapse (POP) is a highly disabling condition common for a vast number of women worldwide. To contribute to existing knowledge in POP pathogenesis, we performed a systematic review of expression studies on both specific gene and whole-genome/proteome levels and an in silico analysis of publicly available datasets related to POP development. The most extensively investigated genes in individual studies were related to extracellular matrix (ECM) organization. Three premenopausal and two postmenopausal sets from two Gene Expression Omnibus (GEO) studies (GSE53868 and GSE12852) were analyzed; Gene Ontology (GO) terms related to tissue repair (locomotion, biological adhesion, immune processes and other) were enriched in all five datasets. Co-expression was higher in cases than in controls in three premenopausal sets. The shared between two or more datasets up-regulated genes were enriched with those related to inflammatory bowel disease (IBD) in the NHGRI GWAS Catalog. ECM-related genes were not over-represented among differently expressed genes. Up-regulation of genes related to tissue renewal probably reflects compensatory mechanisms aimed at repair of damaged tissue. Inefficiency of this process may have different origins including age-related deregulation of gene expression.

Admixture mapping of pelvic organ prolapse in African Americans from the Women's Health Initiative Hormone Therapy trial. PLoS One 2017; 12:e0178839.

Abstract
Evidence suggests European American (EA) women have two- to five-fold increased odds of having pelvic organ prolapse (POP) when compared with African American (AA) women. However, the role of genetic ancestry in relation to POP risk is not clear. Here we evaluate the association between genetic ancestry and POP in AA women from the Women’s Health Initiative Hormone Therapy trial. Women with grade 1 or higher classification, and grade 2 or higher classification for uterine prolapse, cystocele or rectocele at baseline or during follow-up were considered to have any POP (N = 805) and moderate/severe POP (N = 156), respectively. Women with at least two pelvic exams with no indication for POP served as controls (N = 344). We performed case-only, and case-control admixture-mapping analyses using multiple logistic regression while adjusting for age, BMI, parity and global ancestry. We evaluated the association between global ancestry and POP using multiple logistic regression. European ancestry at the individual level was not associated with POP risk. Case-only and case-control local ancestry analyses identified two ancestry-specific loci that may be associated with POP. One locus (Chromosome 15q26.2) achieved empirically-estimated statistical significance and was associated with decreased POP odds (considering grade ≥2 POP) with each unit increase in European ancestry (OR: 0.35; 95% CI: 0.30, 0.57; p-value = 1.48x10-5). This region includes RGMA, a potent regulator of the BMP family of genes. The second locus (Chromosome 1q42.1-q42.3) was associated with increased POP odds with each unit increase in European ancestry (Odds ratio [OR]: 1.69; 95% confidence interval [CI]: 1.28, 2.22; p-value = 1.93x10-4). Although this region did not reach statistical significance after considering multiple comparisons, it includes potentially relevant genes including TBCE, and ACTA1. Unique non-overlapping European and African ancestry-specific susceptibility loci may be associated with increased POP risk.

Abstract
The molecular mechanisms responsible for sepsis-induced endothelial dysfunction leading to an elevated risk of cardiovascular diseases remain undefined. Endotoxic or septic shock is a potentially lethal complication of systemic infection by Gram-negative bacteria. Lipopolysaccharide (LPS) is a critical glycolipid component of the outer wall of Gram-negative bacteria, and many of the sepsis-associated cellular signals by Gram-negative bacteria are attributed to LPS. Given that LPS has an established role in the pathophysiology of sepsis and long non-coding RNAs (lncRNAs) have been reported to critically regulate vascular homeostasis, a systematic transcriptional survey was conducted to evaluate the impact of LPS stimulation on human endothelial lncRNAs and protein-coding transcripts (mRNAs). LncRNAs and mRNAs from LPS-treated (100 ng/mL; 24 h) human umbilical vein endothelial cells (HUVECs) were profiled with the Arraystar Human lncRNA Expression Microarray V3.0. Of the 30,584 lncRNAs screened, 871 were significantly upregulated and 1068 significantly downregulated (p < 0.05) in response to LPS. In the same HUVEC samples, 733 of the 26,106 mRNAs screened were upregulated and 536 were downregulated. Among the differentially expressed lncRNAs, AL132709.5 was the most upregulated (~70 fold) and CTC-459I6.1 the most downregulated (~28 fold). Bioinformatics analyses indicated that the differentially expressed upregulated mRNAs are primarily enriched in cytokine-cytokine receptor interaction, infectious diseases, TNF signaling pathway, FoxO signaling pathway, and pathways in cancer. This is the first lncRNA and mRNA transcriptome profile of LPS-mediated changes in human endothelial cells. These observations may reveal novel endothelial targets of LPS that may be involved in the vascular pathology of sepsis.
