Type 1 diabetes mellitus (T1D) is a complex disorder characterized by an autoimmune response against human pancreatic beta-cells. Patients with T1D can also develop a response toward one or more other factors, such as in autoimmune thyroiditis (AITD) and celiac disease (CD). In the presence of T1D + AITD, the patient is diagnosed with autoimmune polyglandular syndrome type III (APSIII); patients with APSIII may also present with CD. These diseases have a strong genetic component and share many susceptibility genes, suggesting potentially overlapping pathogenic pathways.
Type 1 diabetes mellitus
Previous studies have indicated that the protein tyrosine phosphatase nonreceptor type 22 gene (PTPN22) is associated with type 1 diabetes (T1DM) in the Caucasian population. In the present study, we investigated the relationship between PTPN22 genetic polymorphisms and T1DM in Chinese children. A total of 202 children and adolescents with T1DM and 240 healthy control subjects of Chinese Han origin were included in our analysis.
We investigated the effects of type 1 diabetes mellitus (T1DM) on endothelial progenitor cells (EPCs) at the molecular level and assessed the therapeutic potential of folic acid (FA) in DM. We downloaded the gene expression profile of the EPCs from T1DM patients before and after treatment with FA and from healthy controls. We identified the differentially expressed genes (DEGs) in the EPCs from T1DM patients before and after a four-week period of FA treatment and compared them with those obtained from the healthy subjects by using limma package in R language.
