Journal of Diabetes (JDB) is an open access diabetes and metabolism journal devoted to diabetes research, therapeutics, and education. The journal aims to involve researchers and practitioners in a dialogue between East and West via all aspects of epidemiology, etiology, pathogenesis, management, complications and prevention of diabetes, including the molecular, biochemical, and physiological aspects of diabetes. JDB is an official journal of the Chinese Society of Endocrinology endorsed by the Chinese Endocrinologist Association.

Graphical Abstract

Global, Regional, and National Epidemiology of Vision Impairment due to Diabetic Retinopathy Among Working-Age Population, 1990–2021 Issue 7, 2025

From 1990 to 2021, there has been a substantial increase in the global burden of vision impairment due to diabetic retinopathy among working-age individuals.

Characterization of Novel WFS1 Variants in Three Diabetes Pedigrees

Graphical Abstract

Characterization of Novel WFS1 Variants in Three Diabetes Pedigrees Issue 7, 2025

We first collected the patients with diabetes, including the clinical data and blood. Then the high-throughput sequencing platform was used to detected gene mutation using blood samples. After screening the possible mutation sites, we collected blood from the patient's family members and performed Sanger sequencing for verification. And we analyzed their pathogenicity and conservation using bioinformatics software, and constructed a three-dimensional Wolfram protein structure. Finally, we analyzed the distribution of WFS1 mutations and associated clinical phenotypes by summarizing the genetic variations of the WFS1 gene recorded in the Human Gene Mutation Database. We got results as follows: (1) c.1523_ 1524 del/p Y508Cfs*34 is a frameshift mutation, c.766A>G/p. K256E and c.985T>A/p. F329I are missense mutations. (2) c.766A>G/p. K256E is a benign and novel mutation, while the rest are pathogenic mutations. (3) c.985T>A/p. F329I can cause MODY in a family. (4) Phenotype and clinical presentations diverse in patients with WFS1-associated disease. (5) The proportion of WFS1 mutations corresponding to different clinical phenotypes were highest in missense mutations, mainly distributed in exon 8. We concluded that c.766A>G/p.K256E is a new WFS1 mutation that has never been reported before, and that inactivating mutations and benign missense mutations lead to more severe WS phenotypes than pure pathogenic missense mutations. We also verified that c.985T>A/p. F329I as a MODY-related gene. Finally, by summarizing the genotype–phenotype relationship of WFS1, we concluded that the clinical manifestations of WFS1 mutation-related disease are diverse and require accurate differential diagnosis based on laboratory tests and genetic sequencing.

Potential Significance of Targeting Ferroptosis for Intervention of Diabetic Cardiomyopathy

  •  19 June 2025

Graphical Abstract

Potential Significance of Targeting Ferroptosis for Intervention of Diabetic Cardiomyopathy Issue 6, 2025

The pathophysiology of DCM encompasses insulin resistance and hyperglycemia-induced metabolic alterations in cardiomyocytes, mitochondrial dysfunction and oxidative stress, cardiac lipotoxicity, dysregulation of immune responses, endoplasmic reticulum (ER) stress, impaired calcium handling, and activation of the renin-angiotensin-aldosterone system (RAAS). Oxidative stress results in cardiomyocyte hypertrophy, myocardial fibrosis, cardiomyocyte ferroptosis and immune property modulation and ultimately lead to HFpEF. Ferroptosis inhibitors hold great promise as therapeutic agents for the intervention of DCM.
