Fetal exposure to maternal GDM increases offspring risk for adult-onset metabolic syndromes. Epigenetic modifications such as DNA methylation are modulators for fetal metabolic programming and susceptibility to adult-onset disease. This study investigates genome-wide DNA methylation in GDM exposed cord blood and placenta.

Oral glucose tolerance testing between 24 and 28weeks of pregnancy was used to determine severity of glucose intolerance. We measured DNA methylation (DNAm) using the Illumina Infinium 450K array in 42 fetal cord blood and 36 placenta samples.

We identified 662 and 99 CpG sites in GDM placenta and cord blood, respectively at p-value <0.01 and a methylation difference >5% after adjustment for confounders. Annotated sites for AHRR and PTPRN2 were common to cord blood and placenta. Adding published GDM cord blood DNAm data we segregated patients based on treatment (Diet Only vs. +Insulin) and identified altered CpG sites to be unique to each GDM treatment group.

Consistency in findings with other studies provides evidence for the role of DNAm in placental and fetal responses to hyperglycemia. However, segregating DNAm analysis of GDM samples based on treatment may help delineate whether observed DNAm alterations are reflective of adaptive responses or treatment effects in utero.

To evaluate the risk of all-cause and cardiovascular mortality, acute myocardial infarction, and stroke associated with insulin treatment in patients with type 2 diabetes.

A systematic review with meta-analysis of randomized clinical trials (RCTs) was performed. EMBASE, Cochrane, and PubMed databases were searched for RCTs reporting mortality or cardiovascular events and comparing basal insulin to any treatment in patients with type 2 diabetes. Data were summarized with Mantel-Haenzel relative risk (RR). Trial sequential analysis (TSA) was used to evaluate the reliability of the results considering a 20% relative risk difference between treatments. PROSPERO Registry CRD42018087336.

In total, 2351 references were identified, and 26 studies (24348 patients) were included. Most studies evaluated glargine insulin (69%), compared insulin to GLP-1 analogs (57%), and evaluated add-on therapy with metformin (77%). Insulin was not associated with increased all-cause mortality (RR 0.99; 95% confidence interval (CI) 0.92-1.06), cardiovascular mortality (RR 1.01; 95% CI 0.91-1.13), myocardial infarction (RR 1.02; 95% CI 0.92-1.15), or stroke (RR 0.87; 95% CI 0.68-1.12). Insulin treatment increased severe hypoglycemia risk (RR 2.98; 95% CI 2.47-3.61). All analyses had low statistical heterogeneity. TSA confirmed these findings optimal sample size (myocardial infarction), futility boundary (all-cause mortality, cardiovascular mortality, and stroke) and harm boundary (hypoglycemia) were reached.

Treatment with basal insulin of patients with type 2 diabetes does not increase the risk of cardiovascular events or death. Despite the increased risk of hypoglycemia, these findings reinforce that insulin is a safe option in the treatment of type 2 diabetes.

Systemic inhibition of dipeptidyl peptidase 4 (DPP4) showed a protective effect in several transplant models. Here we assessed the specific role of extrarenal DPP4 in renal transplant rejection.

Kidneys from wildtype (wt) F344 rats were either transplanted in wt Dark Agouti or congenic rats not expressing DPP4. The remaining, not transplanted donor kidney served as healthy controls. To investigate early inflammatory events rats were sacrificed 3days after transplantation and kidneys were evaluated for inflammatory cells, capillary rarefaction, proliferation, apoptosis and myofibroblasts by immunohistochemistry.

Capillary ERG-1-positive endothelial cells were significantly more abundant in renal cortex when transplanted into DPP4 deficient compared to wt recipients. In contrast, TGF-ß and myofibroblasts were reduced by more than 25% in kidneys transplanted into DPP4 deficient compared to wt recipients. Numbers of CD161a-positive NK-cells were significantly lower in allografts in DPP4 deficient compared to wt recipients. Numbers of all other investigated immune cells were not affected by the lack of extrarenal DPP4.

In early transplant rejection extrarenal DPP4 is involved in the recruitment of NK-cells and early fibrosis. Beneficial effects were less pronounced than reported for systemic DPP4 inhibition, indicating that renal DPP4 is an important player in transplantation-mediated injury.

Across the various mAb programs at our company, we observed that increasing the specific productivity (qp) results in a decrease in the % galactosylation (%Gal) level on the protein. In order to gain further insight into this correlation, cells were cultured under different process conditions such as pH or media osmolality or in the presence of supplements such as sodium butyrate. A range of qp and N-glycan profiles were obtained with the greatest changes observed under high pH (lower qp, higher %Gal), higher osmolality (higher qp, lower %Gal) or sodium butyrate (moderately higher qp, moderately lower %Gal) conditions. Abundance of individual glycan species highlighted different bottlenecks in the N-glycosylation pathway depending on the treatment condition. Transcriptomics analysis was performed to identify changes in gene expression profiles that correlate with the inverse relationship between qp and %Gal.
