Special Issue Information

Dear Colleagues,

Obesity, diabetes, and metabolic syndrome are interconnected conditions that influenced by multiple factors, including genetic, environmental, and lifestyle factors. Each condition has both unique genetic components and genetic mechanisms that contribute to their development. Genetics play a significant role in determining an individual’s susceptibility to obesity and type 2 diabetes. Certain genetic variations can influence factors, such as metabolism, appetite regulation, fat storage, and insulin sensitivity.

Obesity is closely linked to the development of type 2 diabetes. Excess body fat, particularly abdominal fat, can contribute to the development of type 2 diabetes. Additionally, shared genetic factors can contribute to both obesity and insulin resistance, further connecting the two conditions. Both obesity and type 2 diabetes involve metabolic dysfunction. In obesity, there is often an imbalance between energy intake and expenditure, leading to the excess accumulation of fat and disruptions in metabolic processes. Similarly, type 2 diabetes is characterized by impaired glucose metabolism, insulin resistance, and the dysregulation of various metabolic pathways. These metabolic dysfunctions contribute to the development and progression of both conditions.

Understanding the connections among genetic factors, obesity, diabetes, and metabolic dysfunction is important for identifying individuals at higher risk, developing preventive strategies, and tailoring personalized interventions for the better management of these conditions.

This Special Issue aims to present cutting-edge research and comprehensive reviews that provide the most updated explanations of topics concerning metabolic diseases:

  1. The identification of genetic markers associated with obesity, type 2 diabetes, and metabolic dysfunction;
  2. Molecular and biochemical mechanisms underlying metabolic diseases;
  3. Novel natural approaches for the potential prevention and therapeutic strategies of obesity, diabetes, and related conditions;
  4. Multiomics used to study metabolic diseases.

This study investigates the distribution of hyperhomocysteinemia and cardiovascular metabolic syndrome (SM) among participants, shedding light on their prevalence and co-occurrence within the study cohort. Through an analysis of demographic characteristics and health parameters, including age, gender, and body mass index (BMI), alongside nutritional data, correlations between these factors and health risks are explored. Results reveal a notable prevalence of hyperhomocysteinemia, with 45.3% of participants exhibiting this condition. Furthermore, 31.4% of the cohort does not present hyperhomocysteinemia or SM, while 23.3% shows SM without hyperhomocysteinemia. The study underscores gender-specific dietary recommendations due to significant variations in nutrient intake patterns. Additionally, inverse correlations between health risks like obesity, hypertension, and hypercholesterolemia and nutrient requirements highlight the need for tailored dietary interventions. Age-related changes in nutrient needs and the positive correlation between physical activity levels and certain nutrient demands further emphasize the importance of personalized dietary strategies. Variations in nutrient intake by gender, inverse correlations with health risks, and age-related changes underscore the need for tailored dietary strategies. These findings provide valuable insights for healthcare professionals in developing targeted nutritional interventions to mitigate disease risk and promote overall health and well-being. Full article

An epigenomic approach was used to study the impact of maternal pregestational body mass index (BMI) on the placenta and umbilical cord methylomes and their potential effect on the offspring’s metabolic phenotype. DNA methylome was assessed in 24 paired placenta and umbilical cord samples. The differentially methylated CpGs associated with maternal pregestational BMI were identified and the metabolic pathways and the potentially related diseases affected by their annotated genes were determined. Two top differentially methylated CpGs were studied in 90 additional samples and the relationship with the offspring’s metabolic phenotype was determined. The results showed that maternal pregestational BMI is associated with the methylation of genes involved in endocrine and developmental pathways with potential effects on type 2 diabetes and obesity. The methylation and expression of HADHA and SLC2A8 genes in placenta and umbilical cord were related to several metabolic parameters in the offspring at 6 years (weight SDS, height SDS, BMI SDS, Δ BW-BMI SDS, FM SDS, waist, SBP, TG, HOMA-IR, perirenal fat; all p < 0.05). Our data suggest that epigenetic analysis in placenta and umbilical cord may be useful for identifying individual vulnerability to later metabolic diseases. Full article

Abstract
Hypertension (HT) is a disease that poses a serious threat to human health, mediating organ damage such as the cardiovascular (CV) system, kidneys, central nervous system (CNS), and retinae, ultimately increasing the risk of death due to damage to the entire vascular system. [...] Read more.
Hypertension (HT) is a disease that poses a serious threat to human health, mediating organ damage such as the cardiovascular (CV) system, kidneys, central nervous system (CNS), and retinae, ultimately increasing the risk of death due to damage to the entire vascular system. Thus, the widespread prevalence of hypertension brings enormous health problems and socioeconomic burdens worldwide. The goal of hypertension management is to prevent the risk of hypertension-mediated organ damage and excess mortality of cardiovascular diseases. To achieve this goal, hypertension guidelines recommend accurate monitoring of blood pressure and assessment of associated target organ damage. Early identification of organ damage mediated by hypertension is therefore crucial. Plasma biomarkers as a non-invasive test can help identify patients with organ damage mediated by hypertension who will benefit from antihypertensive treatment optimization and improved prognosis. In this review, we provide an overview of some currently available, under-researched, potential plasma biomarkers of organ damage mediated by hypertension, looking for biomarkers that can be detected by simple testing to identify hypertensive patients with organ damage, which is of great significance in clinical work. Natriuretic peptides (NPs) can be utilized as a traditional biomarker to detect hypertension-mediated organ damage, especially for heart failure. Nevertheless, we additionally may need to combine two or more plasma biomarkers to monitor organ damage in the early stages of hypertension. Full article

Background: Age at menarche (AAM) has been associated with type 2 diabetes mellitus (T2DM). However, little is known about their shared heritability. Methods: Our data comes from the Taiwan Biobank. Genome-wide association studies (GWASs) were conducted to identify single-nucleotide polymorphisms (SNPs) related to AAM-, T2DM-, and T2DM-related phenotypes, such as body fat percentage (BFP), fasting blood glucose (FBG), and hemoglobin A1C (HbA1C). Further, the conditional false discovery rate (cFDR) method was applied to examine the shared genetic signals. Results: Conditioning on AAM, Quantile-quantile plots showed an earlier departure from the diagonal line among SNPs associated with BFP and FBG, indicating pleiotropic enrichments among AAM and these traits. Further, the cFDR analysis found 39 independent pleiotropic loci that may underlie the AAM-T2DM association. Among them, FN3KRP rs1046896 (cFDR = 6.84 × 10−49), CDKAL1 rs2206734 (cFDR = 6.48 × 10−10), B3GNTL1 rs58431774 (cFDR = 2.95 × 10−10), G6PC2 rs1402837 (cFDR = 1.82 × 10−8), and KCNQ1 rs60808706 (cFDR = 9.49 × 10−8) were highlighted for their significant genetic enrichment. The protein–protein interaction analysis revealed a significantly enriched network among novel discovered genes that were mostly found to be involved in the insulin and glucagon signaling pathways. Conclusions: Our study highlights potential pleiotropic effects across AAM and T2DM. This may shed light on identifying the genetic causes of T2DM. Full article
