Microplastics (MPs) are environmental pollutants with potential health risks. This study examined the effect of MPs on wound healing in both diabetic and non-diabetic mice. MPs exposure significantly delayed wound healing, particularly in diabetic mice, with reduced epidermal thickness and impaired collagen deposition.

Mitochondrial glucose metabolism is critical for glucose-stimulated insulin secretion and glucose homeostasis in pancreatic β cells. We previously showed that KCNH6, a voltage-dependent potassium (Kv) channel, participated regulation of insulin secretion in pancreatic β cells, however, its role in mitochondrial metabolism remains unclear. Since we recently found that KCNH6 distributed in mitochondria, in this study, we investigated the role of KCNH6 in regulating mitochondrial function in pancreatic β cells by using a β cell-specific knockout (KCNH6-βKO) mouse model.

Ganoderma mushrooms are popularly used as dietary supplements to promote health around the world. However, their potential applications for the prevention and treatment of obesity needs to be further investigated. In this study, we isolated a novel triterpenoid from Ganoderma resinaceum, Resinacein S (Res S), and determined its absolute configuration.

Pregnancy requires the coordination of metabolically active organs to support maternal nutrition and fetal growth. However, the metabolic cross-talk between adipose tissue and liver in females during pregnancy is still less clear. In this study, we evaluated the metabolic adaptations and phenotypes of liver in response to pregnancy-associated metabolic stress, particularly in the context of genetic ablation of Uncoupling protein 1 (Ucp1)-mediated catabolic circuit.

Introduction: Lung cancer is a major health concern worldwide owing to its high incidence and mortality rates. Therefore, identification of new therapeutic targets and strategies for lung cancer is critical for improving patient outcomes. Peptidyl arginine deiminase 4 (PAD4) promotes tumor growth and metastasis by catalyzing the citrullination of histones, making it a potential therapeutic target.

Insulin secretion is mainly regulated by two electrophysiological events, depolarization initiated by the closure of adenosine triphosphate (ATP)-sensitive K+ (KATP) channels and repolarization mediated by K+ efflux. Quinine, a natural component commonly used for the treatment of malaria, has been reported to directly stimulate insulin release and lead to hypoglycemia in patients during treatment through inhibiting KATP channels. In this study, we verified the insulinotropic effect of quinine on the isolated mouse pancreatic islets.

Background: Developing countries face an "obesity epidemic," particularly affecting children and younger adults. While obesity is a known risk factor for 12 types of cancer, primarily affecting older populations, its impact on younger generations is understudied.

Methods: This study analyzed data from a population-based cancer registry covering 14.

Article Synopsis
  • Diabetes raises the risk of severe COVID-19 outcomes, with Cathepsin L (CTSL) linked to complications like nephropathy and retinopathy.
  • Research shows that higher blood levels of CTSL in diabetic patients enhance SARS-CoV-2 infection, influenced by chronic and acute hyperglycemia.
  • Studies indicate that elevated glucose levels, not insulin, increase CTSL activity and promote virus infection, as demonstrated through experiments with human and mouse cells.

Derived from enteroendocrine cells (EECs), glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) are pivotal incretin hormones crucial for blood glucose regulation. Medications of GLP-1 analogs and GLP-1 receptor activators are extensively used in the treatment of type 2 diabetes (T2D) and obesity. However, there are currently no agents to stimulate endogenous incretin secretion.

Article Synopsis
  • Atrial fibrillation (AF) increases the risk of stroke and death, and this study investigates how β-catenin may influence atrial fibrosis in humans, using human right atrial appendage (hRAA) tissues.
  • The research compared β-catenin levels in AF patients versus those with normal sinus rhythm, and also used mice and primary cells to explore β-catenin's role in AF development.
  • Key findings showed that AF patients had wider gaps in cardiomyocyte junctions, increased β-catenin expression, decreased gap junction proteins, and that inhibiting β-catenin could prevent both atrial fibrosis and AF in model mice.

Cathepsin L (CTSL) is a promising therapeutic target for metabolic disorders. Current pharmacological interventions targeting CTSL have demonstrated potential in reducing body weight gain, serum insulin levels, and improving glucose tolerance. However, the clinical application of CTSL inhibitors remains limited.

Article Synopsis
  • Pregnancy leads to significant changes in metabolism to support fetal growth, especially affecting adipose tissues.
  • During late pregnancy, mice showed increased insulin resistance and glucose intolerance, which improved after giving birth.
  • Different types of fat tissues adapted uniquely, with some showing decreased energy use and others increased lipid mobilization, suggesting a complex role in energy supply and potential risks for metabolic diseases in mothers.

Appropriate Ca concentration in the endoplasmic reticulum (ER), modulating cytosolic Ca signal, serves significant roles in physiological function of pancreatic β cells. To maintaining ER homeostasis, Ca movement across the ER membrane is always accompanied by a simultaneous K flux in the opposite direction. KCNH6 was proven to modulate insulin secretion by controlling plasma membrane action potential duration and intracellular Ca influx.

Glucose-stimulated insulin secretion (GSIS) in pancreatic islet β-cells primarily relies on electrophysiological processes. Previous research highlighted the regulatory role of KCNH6, a member of the Kv channel family, in governing GSIS through its influence on β-cell electrophysiology. In this study, we unveil a novel facet of KCNH6's function concerning insulin granule exocytosis, independent of its conventional electrical role.

Objective: Genome-scale CRISPR-Cas9 knockout coupled with single-cell RNA sequencing (scRNA-seq) has been used to identify function-related genes. However, this method may knock out too many genes, leading to low efficiency in finding genes of interest. Insulin secretion is controlled by several electrophysiological events, including fluxes of K depolarization and K repolarization.

Background: With the rapid advancement of medical imaging technology, the demand for accurate segmentation of medical images is increasing. However, most existing methods are unable to capture locality and long-range dependency information in integrated ways for medical images.

Method: In this paper, we propose an elegant segmentation framework for medical images named TC-Net, which can utilize both the locality-aware and long-range dependencies in the medical images.
