Summary: The pancreas plays a critical role in regulating glucose homeostasis through hormone secretion. A systematic modeling workflow was used to develop a kinetic model of glucose-stimulated insulin secretion (GSIS) in the pancreatic β-cell. The model includes detailed glycolysis and phenomenological equations for insulin secretion, and it is based on experimental and clinical data from various studies.

Summary: The synthesis of two novel cationic [Ir(C^N)2)(N^N)](+) complexes containing deprotonated 1-phenyl-1H-pyrazole or 1-(2,4-difluorophenyl)-1H-pyrazole (C^N) as cyclometalating and 1,10-phenanthroline derivatives (N^N) as ancillary ligands is reported. The complexes exhibit strong luminescence at room temperature in acetonitrile solutions and at 77 K in CH3OH/C2H5OH 1:1 glasses, with luminescence properties depending on the type of ligands and measurement temperature.

Summary: This study investigated the role of the Ghrelin receptor (GHS-R) in glucose-stimulated insulin secretion (GSIS) and its interaction with the insulin signaling pathway in pancreatic islets. The findings suggest that GHS-R affects key components of the insulin signaling pathway, likely regulating GSIS via the Akt-Pdx1-GLUT2 pathway.

Summary: This study investigated the impact of PFOS exposure on GSIS in INS-1 cells and the potential protective effects of PC. After 48 h of exposure, the effects of PFOS and/or PC on GSIS were examined. Results showed that PFOS exposure did not significantly affect cell viability but reduced insulin secretion and relative mRNA expression levels. Furthermore, PFOS exposure led to an increase in ROS activity, which was alleviated by PC intervention.

Summary: Breast cancer is a common malignant tumor in women, and drug resistance remains a clinical challenge. In this study, a novel compound, G-5b, was developed with potent antagonistic and degradation activities comparable to the current drug fulvestrant. G-5b also showed improved stability and solubility. Mechanistically, G-5b engages the proteasome pathway to degrade ER, inhibiting the ER signaling pathway and inducing apoptosis and cell cycle arrest. In animal models, G-5b exhibited superior pharmacokinetics and pharmacodynamics properties. Overall, G-5b is a promising long-acting SERD worthy of further investigation and optimization.
