Genetic, parental and lifestyle factors influence telomere length
No full textThe average length of telomere repeats (TL) declines with age and is considered to be a marker of biological ageing. Here, we measured TL in six blood cell types from 1046 individuals using the clinically validated Flow-FISH method. We identified remarkable cell-type-specific variations in TL. Host genetics, environmental, parental and intrinsic factors such as sex, parental age, and smoking are associated to variations in TL. By analysing the genome-wide methylation patterns, we identified that the association of maternal, but not paternal, age to TL is mediated by epigenetics. Single-cell RNA-sequencing data for 62 participants revealed differential gene expression in T-cells. Genes negatively associated with TL were enriched for pathways related to translation and nonsense-mediated decay. Altogether, this study addresses cell-type-specific differences in telomere biology and its relation to cell-type-specific gene expression and highlights how perinatal factors play a role in determining TL, on top of genetics and lifestyle.We thank J.

Clinical implications of shared genetics and pathogenesis in autoimmune diseases
No full text<p>Many endocrine diseases, including type 1 diabetes mellitus, Graves disease, Addison disease and Hashimoto disease, originate as an autoimmune reaction that affects disease-specific target organs. These autoimmune diseases are characterized by the development of specific autoantibodies and by the presence of autoreactive T cells. They are caused by a complex genetic predisposition that is attributable to multiple genetic variants, each with a moderate-to-low effect size. Most of the genetic variants associated with a particular autoimmune endocrine disease are shared between other systemic and organ-specific autoimmune and inflammatory diseases, such as rheumatoid arthritis, coeliac disease, systemic lupus erythematosus and psoriasis. Here, we review the shared and specific genetic background of autoimmune diseases, summarize their treatment options and discuss how identifying the genetic and environmental factors that predispose patients to an autoimmune disease can help in the diagnosis and monitoring of patients, as well as the design of new treatments.</p>
The importance of cohort studies in the post-GWAS era
No full textThe past decade has seen enormous success of wide-scale genetic studies in identifying genetic variants that modify individuals' predisposition to common diseases. However, the interpretation and functional understanding of these variants lag far behind. In this Perspective, we discuss opportunities for using large-scale cohort studies to investigate the downstream molecular effects of SNPs at different 'omics' data levels. We point to the pivotal role of population cohorts in establishing causality and advancing drug discovery. In particular, we focus on the breadth-versus-depth concepts of population studies, on data harmonization, and on the challenges, ethical aspects and future perspectives of cohort studies
Gut Microbiome and Female Health
No full textOur understanding of the gut microbiome has taken a huge leap in the past five years. We now know that the composition of the gut microbiome is extremely complex and that it is affected by a large number of host and environmental factors. [1] While studying the association of various factors with the gut microbiome, sex is a factor that is often corrected for. In this paper we throw light upon the studies focusing on how sex influences microbiome. We compare the female and male gut microbiome and discuss the relationship between the gut microbiome and sex hormones. We describe the current body of knowledge regarding the important hormonal changes that occur in a female’s life and the associations of these changes with the gut microbiome. We also describe our own findings in relation to sex-related traits such as diet, medication and disease. The knowledge gained demonstrates the importance of studying the gut microbiome in relation to female physiological processes in order to understand the character of the ‘normal’ female gut microbiome
