Defective insulin-stimulated equilibrative nucleoside transporter-2 activity and altered subcellular transporter distribution drive the loss of adenosine homeostasis in diabetic kidney disease progression
CONCLUSION: Deficient insulin regulation of ENT2 activity contributes to chronically high adenosine levels and glomerular alterations that underline diabetic kidney disease progression.PMID:37734469 | DOI:10.1016/j.bbadis.2023.166890

Temporal optimization of exercise to lower fasting glucose levels
This study examined the effect of exercise timing on evening and overnight glucose concentrations in individuals who were non-obese with normal fasting glucose levels (Non-Ob; n = 18) and individuals with obesity (OB) with impaired fasting glucose levels (OB+IFG) and without (n = 16 and n = 18, respectively). Subjects were studied on three occasions (no exercise (NOEX)), morning exercise (AMEX; 0700 h) and evening exercise (PMEX; 2000 h). The evening meal was provided (1800 h) and blood samples were taken from 1740 to 0700 h and morning endogenous glucose production (EGP) was measured. Glucose and insulin concentrations in...

How online peer support affects management efficacy and mitigates difficulties of parents caring for children with type 1 diabetes
Prim Care Diabetes. 2023 Sep 18:S1751-9918(23)00162-6. doi: 10.1016/j.pcd.2023.09.003. Online ahead of print.ABSTRACTThe proper management of pediatric type 1 diabetes depends substantially on the parents of affected children. Parental psychological traits specifically related to diabetes caregiving influence the quality of their care and management of the disease in their children. Parents often use Facebook groups as sources of peer support and information about diabetes care. The present study aimed to examine the influence of devices used in diabetes management, ascertain the impact of Facebook peer-support groups on p...

Are menstrual disorders in adolescent girls related to metabolic disorders?
CONCLUSIONS: Adolescent girls with menstrual disorders are insulin resistant, regardless of PCOS diagnosis. The severity of menstrual disorders may be related to the incidence of lipid disorders in adolescent girls.PMID:37728458 | PMC:PMC10411084 | DOI:10.5114/pedm.2023.125364

In vitro oxygen imaging of acellular and cell-loaded beta cell replacement devices
This article aims to establish the protocols and demonstrate a few examples of in vitro oxygen imaging of BAP devices using EPROI. All pO2 measurements were performed using a recently introduced 720 MHz/25 mT preclinical oxygen imager instrument, JIVA-25™. We began by performing pO2 calibration of the biomaterials used in BAPs at 25 mT magnetic field since no such data exist. We compared the EPROI pO2 measurement with a single-point probe for a few selected materials. We also performed trityl OX071 toxicity studies with fibroblasts, as well as insulin-producing cells (beta TC6, MIN6, and human islet cells). Finally, we p...

Endoplasmic Reticulum Stress in Pancreatic β-Cells Induces Incretin Desensitization and β-Cell Dysfunction via ATF4-Mediated PDE4D Expression
Am J Physiol Endocrinol Metab. 2023 Sep 20. doi: 10.1152/ajpendo.00156.2023. Online ahead of print.ABSTRACTPancreatic β-cell dysfunction and eventual loss are key steps in the progression of type 2 diabetes (T2D). Endoplasmic reticulum (ER) stress responses, especially those mediated by the PERK-ATF4 pathway, have been implicated in promoting these β-cell pathologies. However, the exact molecular events surrounding the role of the PERK-ATF4 pathway in β-cell dysfunction remain unknown. Here, we report our discovery that ATF4 promotes the expression of PDE4D, which disrupts β-cell function via a downregulation of cAMP s...

Role of the tripartite motif-containing (TRIM) family of proteins in insulin resistance and related disorders
Diabetes Obes Metab. 2023 Sep 19. doi: 10.1111/dom.15294. Online ahead of print.ABSTRACTEmerging evidence suggests that the ubiquitin-mediated degradation of insulin-signalling-related proteins may be involved in the development of insulin resistance and its related disorders. Tripartite motif-containing (TRIM) proteins, a superfamily belonging to the E3 ubiquitin ligases, are capable of controlling protein levels and function by ubiquitination, which is essential for the modulation of insulin sensitivity. Recent research has indicated that some of these TRIMs act as key regulatory factors of metabolic disorders such as ty...

Construction and functional evaluation of oral long-acting insulin hydrogel microparticles based on physical and chemical double crosslinking
The objective of this study was to enhance the convenience and effectiveness of diabetes treatment by developing hydrogel microparticles as an oral insulin delivery system, aiming to reduce the necessity for frequent treatments. The hydrogel microparticles were prepared with polysaccharides through a combination of physical and chemical crosslinking method, they achieved good results in insulin loading efficiency (70 %), insulin release efficiency (98 %) and sustained release time (>20 h). The effective transmembrane transport was validated using an intestinal epithelial cell model, which demonstrated a continuous hypog...

Diabetes Mellitus Drug Discovery: Insights into Targeting Feline and Human Amylin with Small Molecules
Vet Q. 2023 Sep 20:1-20. doi: 10.1080/01652176.2023.2260442. Online ahead of print.ABSTRACTType 2 diabetes (T2D) is a health concern for both humans and cats, with cases rising over the past decade. Around 70% of patients from either species exhibit pancreatic aggregates of islet amyloid polypeptide (IAPP), a protein that proves toxic upon misfolding. These misfolded protein aggregates congregate in the islets of Langerhans of the pancreas, diminishing the capability of β-cells to produce insulin and further perpetuating disease. Our team's drug discovery program is investigating newly synthesized compounds that could dim...
