Melatonin is a naturally occurring neurohormone that participates in the regulation of a large spectrum of biological functions.

Poly-γ-glutamic acid alleviates slow transit constipation by regulating aquaporin and gut microbes.

Slow transit constipation (STC) is a prevalent gastrointestinal disorder caused by colon dysfunction. Poly-γ-glutamic acid (γ-PGA), an anionic polymer known for its moisture retention, degradability, and food safety, was studied for its effects on loperamide-induced STC in mice. Treatment with γ-PGA for one week significantly increased both defecation frequency and fecal water content, with the high-dose group (10 g/kg/d) restoring fecal water content to 34.

Multifunctional nanoparticle-mediated targeting of metabolic reprogramming and DNA damage response pathways to treat drug-resistant triple-negative breast cancer.

Multi-drug resistance and immunosuppressive triple-negative breast cancer (TNBC) is triggered by the Warburg effect, which promotes homologous recombination repair (HRR) and upregulates expression of P-glycoprotein (P-gp), in turn preventing DNA damage from chemotherapy and creating an immunosuppressive microenvironment. It is therefore of clinical relevance to develop an effective delivery system that targets metabolic reprogramming and DNA damage response pathways for the treatment of drug-resistant TNBC. Herein, a P-gp-inhibiting and GSH-responsive multifunctional drug carrier targeting integrin αvβ3 was synthesised for the delivery of Lonidamine-prodrug (M1, glycolysis inhibitor) and Senaparib (Se, Poly [ADP-ribose] polymerase inhibitor).

Choline metabolism in ischemic stroke: An underappreciated "two-edged sword".

Ischemic stroke (IS) is an important cause of death and disability worldwide, but the molecular mechanisms involved are not fully understood. In this context, choline metabolism plays an increasingly important role in IS due to its multifaceted mechanisms involving neuroprotection, neuroregeneration, inflammatory response, immune regulation, and long-term health effects. With the deepening of the research on choline and its metabolites, such as trimethylamine-N-oxide (TMAO), scientists have gradually realized its key role in the occurrence, development and potential treatment of IS.

Deciphering immune predictors of immunotherapy response: A multiomics approach at the pan-cancer level.

Immune checkpoint blockade (ICB) therapy has transformed cancer treatment, yet many patients fail to respond. Employing single-cell multiomics, we unveil T cell dynamics influencing ICB response across 480 pan-cancer and 27 normal tissue samples. We identify four immunotherapy response-associated T cells (IRATs) linked to responsiveness or resistance and analyze their pseudotemporal patterns, regulatory mechanisms, and T cell receptor clonal expansion profiles specific to each response.

Hydrogen generators-protected mesenchymal stem cells reverse articular redox imbalance-induced immune dysfunction for osteoarthritis treatment.

Stem cell therapy has revolutionized the management of osteoarthritis (OA), but the articular dysregulated redox status diminishes cell engraftment efficiency and disrupts immune homeostasis, therefore compromising the overall therapeutic efficacy. Here, we present hydrogen (H) generators-backpacked mesenchymal stem cells (MSCs) which preserve the biological functions and survival of transplanted cells and reverse articular immune dysfunction, mitigating OA. Specifically, post systemic transplantation, H generators-laden MSCs home to OA joints, and upon stimulation in acidic OA environment, H produced from the generators remodels articular redox balance, thereby relieving the loss of mitochondrial membrane potential, decreasing cell apoptosis rate, and maintaining pluripotent and paracrine functions of MSCs.
