Targeting metabolic reprogramming to treat cancer could increase overall survival and reduce side effects. Here, we put forward a strategy using arene-ruthenium(II)/osmium(II) complexes to potentiate the anticancer effect of metformin (Met.) via glucose metabolism reprogramming. Complexes 1-6 with oxoglaucine derivatives as ligands were synthesized and their anti-tumor activities were tested under hypoglycemia. Results indicated that 2 and 5 potentiated the anticancer effects of Met. under hypoglycemia, exhibiting lower toxicity, slower blood glucose decline and inhibition of early tumor liver metastasis. Combination of 5 with Met. could be used as a new strategy to treat cancer under hypoglycemia through glucose metabolism reprogramming.

Gestational diabetes mellitus (GDM) is a metabolic disorder that arises during pregnancy and heightens the risk of placental dysplasia. Ginsenoside Re (Re) may stabilize insulin and glucagon to regulate glucose levels, which may improve diabetes-associated diseases. This study aims to investigate the mechanism of Re in high glucose (HG)-induced apoptosis of trophoblasts through endoplasmic reticulum stress (ERS)-related protein CHOP/GADD153.

Background: To investigate the effectiveness of different bariatric metabolic surgeries in improving metabolic syndrome indicators in patients.

Methods: A retrospective analysis was conducted on obese patients who underwent laparoscopic sleeve gastrectomy (LSG), laparoscopic sleeve gastrectomy + jejunojejunal bypass (LSG + JJB), and laparoscopic Roux-en-Y gastric bypass (LRYGB). Patients were categorized into groups based on their surgical procedure: LSG (N = 199), LSG + JJB (N = 242), and LRYGB (N = 288).

Sublethal tumor cells have an urgent need for energy, making it common for them to switch metabolic phenotypes between glycolysis and oxidative phosphorylation (OXPHOS) for compensatory energy supply; thus, the synchronous interference of dual metabolic pathways for limiting energy level is essential in inhibiting sublethal tumor growth. Herein, a multifunctional nanoplatform of Co-MOF-loaded anethole trithione (ADT) and myristyl alcohol (MA), modified with GOx and hyaluronic acid (HA) was developed, namely, CAMGH. It could synchronously interfere with dual metabolic pathways including glycolysis and OXPHOS to restrict the adenosine triphosphate (ATP) supply, achieving the inhibition to sublethal tumors after microwave (MW) thermal therapy.

The Cullin-3 E3 ligase adaptor protein SPOP targets proteins for ubiquitination and proteasomal degradation. We previously established the β-cell transcription factor (TF) and human diabetes gene PDX1 as an SPOP substrate, suggesting a functional role for SPOP in the β cell. Here, we generated a β-cell-specific deletion mouse strain ( ) and found that is necessary to prevent aberrant basal insulin secretion and for maintaining glucose-stimulated insulin secretion through impacts on glycolysis and glucose-stimulated calcium flux.
