The gut microbiome-metabolites-kidney axis is a potential target for treating diabetic kidney disease (DKD). Our previous study found that Liraglutide attenuated DKD in rats by decreasing renal tubular ectopic lipid deposition (ELD) and serum metabolites levels, including L-5-Oxoproline (5-OP). However, the response of gut microbiome-metabolites-kidney axis to Liraglutide in DKD rats and the effect of 5-OP on ELD remain unknown.

Objective: Hepatic insulin resistance, which leads to increased hepatic gluconeogenesis, is a major contributor to fasting hyperglycemia in type 2 diabetes mellitus (T2DM). However, the mechanism of impaired insulin-dependent suppression of hepatic gluconeogenesis remains elusive. Delta/Notch-like epidermal growth factor (EGF)-related receptor (DNER), firstly described as a neuron-specific Notch ligand, has been recently identified as a susceptibility gene for T2DM through genome-wide association studies.

Article Synopsis
  • The study investigates how high blood sugar levels (hyperglycemia) affect immune function in patients with COVID-19 who also have type 2 diabetes mellitus (T2DM).
  • It analyzed 65 hospitalized patients, comparing those with well-controlled versus poorly-controlled blood sugar levels, finding significant differences in immune cell counts and inflammatory markers.
  • Results indicate that higher blood glucose levels are linked to lower immune cell counts and increased inflammation, which may worsen the severity of COVID-19 in these patients.

Obesity, a burgeoning worldwide health system challenge, is associated with several comorbidities, including non-alcoholic fatty liver disease (NAFLD), diabetes, atherosclerosis, and osteoarthritis, leading to serious problems to people's health. Adenosine is a critical extracellular signaling molecule that has essential functions in regulating most organ systems by binding to four G-protein-coupled adenosine receptors, denoted A , A , A , and A . Among the receptors, a growing body evidence highlights the key roles of the adenosine 2A receptor (A R) in obesity and related diseases.

Obesity is associated with insulin resistance, diabetes, and obesity-related metabolic disorders. Brown adipocytes have emerged as potential targets for the treatment of obesity and obesity-related diseases. However, changes that occur in brown adipose tissue during various stages of high fat diet (HFD)-induced obesity remain poorly understood.

Adiponectin, an adipokine produced and secreted by adipocytes, is involved in regulating the development and progression of insulin resistance, diabetes, and diabetic complications. Heat shock protein 60 (HSP60) is a molecular chaperone, most commonly presenting in mitochondria and participating in the maintenance of protein homeostasis. Accumulating studies have demonstrated that the elevated circulating HSP60 and the decreased intracellular HSP60 are closely associated with diabetic complications such as diabetic cardiomyopathy.

Adipocyte dysfunction is closely associated with the development of obesity, insulin resistance, and type 2 diabetes. In addition to having a positive effect on adiponectin pathway and insulin signaling through direct and/or indirect mechanisms, adapter protein APPL1 has also been reported to regulate body weight, brown fat tissues thermogenesis, and body fat distribution in diabetic individuals. However, there is dearth of data on the specific role of APPL1 on adipogenic differentiation and adipocyte lipolysis.

Angiopoietin-like 8 (ANGPTL8) is closely linked to obesity-associated metabolic diseases and insulin resistance. The aim of the current study was to investigate the ability of ANGPTL8 to reverse insulin resistance in obese mice. The administration of ANGPTL8 reduced weight gain and improved glucose tolerance in mice with diet-induced obesity.

  • MTHFR (methylenetetrahydrofolate reductase) is linked to hyperhomocysteinemia, which may increase the risk for congenital heart defects (CHD), but its specific association has been unclear.
  • An updated meta-analysis combining data from 16 studies found a significant link between the MTHFR A1298C polymorphism and CHD, particularly in patients without Down Syndrome.
  • The study concludes that the MTHFR 1298C allele may be a risk factor for CHD, highlighting the need for more research on related factors like homocysteine levels and folic acid supplementation.

Background: Type 2 diabetes mellitus (T2DM) is a recognized trigger factor for heart failure with preserved ejection fraction (HFpEF). Recent studies show that higher serum calcium level is associated with greater risk of both T2DM and heart failure. We speculate that increased serum calcium is related to HFpEF prevalence in patients with T2DM.

Background: To explore the association between maternal alcohol consumption and/or binge drinking and congenital heart defects (CHDs), we conducted a meta-analysis for more sufficient evidence on this issue.

Methods: We searched Medline, EMBASE, and the Cochrane Library from their inceptions to December 2014 for case-control and cohort studies that assessed the association between maternal alcohol consumption and CHD risk. Study-specific relative risk estimates were calculated using random-effect or fixed-effect models.
