GV-971 prevents severe acute pancreatitis by remodeling the microbiota-metabolic-immune axis.

Nat Commun

September 2024

Affiliated Cancer Hospital & Institute of Guangzhou Medical University, Guangzhou Municipal and Guangdong Provincial Key Laboratory of Protein Modification and Disease, State Key Laboratory of Respiratory Disease, School of Basic Medical Sciences, Guangzhou Medical University, Guangzhou, 511436, China.

Despite recent advances, severe acute pancreatitis (SAP) remains a lethal inflammation with limited treatment options. Here, we provide compelling evidence of GV-971 (sodium oligomannate), an anti-Alzheimer's medication, as being a protective agent in various male mouse SAP models. Microbiome sequencing, along with intestinal microbiota transplantation and mass cytometry technology, unveil that GV-971 reshapes the gut microbiota, increasing Faecalibacterium populations and modulating both peripheral and intestinal immune systems.

Article Synopsis
  • Fructose-1,6-bisphosphatase (FBPase) is a key target in managing elevated blood glucose in type 2 diabetes, and compounds that inhibit it could offer effective treatments.
  • A new molecular docking method revealed compound 45, which has a benzimidazole structure, showing strong inhibition of FBPase (IC, 2.08 μM) similar to the diabetes drug metformin in mice tests.
  • Importantly, compound 45 does not affect major human cytochrome P450 enzymes, suggesting a lower risk of drug interactions and potential for further development as an effective FBPase inhibitor.

Electronic address:

The Polypyrimidine Tract-Binding Protein-Associated Splicing Factor (PSF), a component of the Drosophila Behavior/Human Splicing (DBHS) complex, plays a pivotal role in cancer pathogenesis. The epigenetic regulation mediated by PSF and long noncoding RNA (lncRNA), along with PSF's alternative splicing activity, has been implicated in promoting cancer cell proliferation, migration, invasion, metastasis, and drug resistance in various human cancers. Recent research highlights the therapeutic promise of targeting the PSF-lncRNA interaction to combat aggressive malignancies, making it a compelling target for cancer therapy.

Macrophage elaboration of inflammatory responses is dynamically regulated, shifting from acute induction to delayed suppression during the course of infection. Here, we show that such regulation of inflammation is modulated by dynamic shifts in metabolism. In macrophages exposed to the bacterial product lipopolysaccharide (LPS), an initial induction of protein biosynthesis is followed by compensatory induction of the transcription factor nuclear factor erythroid 2-like 1 (NRF1), leading to increased flux through the ubiquitin proteasome system (UPS).

Article Synopsis
  • The study finds that the YTHDF1 protein, which reads N6-methyladenosine on RNA, plays a crucial role in cancer progression and is upregulated in dendritic cells (DCs) after radiotherapy (RT).
  • High levels of YTHDF1 in DCs are linked to worse patient outcomes during RT, while removing or inhibiting YTHDF1 boosts the effectiveness of radiation therapy in cancer models.
  • The research uncovers a regulatory mechanism between YTHDF1 and the STING signaling pathway, suggesting that targeting YTHDF1 could improve cancer treatment strategies such as RT and radioimmunotherapy.

Visible-light photooxidation sensitized by surface attachment of small colorless organics on semiconductor photocatalysts has emerged as an economical method for photocatalytic synthesis or degradation. In particular, heteroatom (X = N and Cl)-containing substrates could undergo either C-N coupling or dechlorination degradation sensitizing TiO, but the mechanism in conducting the competitive visible-light sensitized photooxidations is still vague. Herein, the visible-light photooxidation of colorless 4-chlorobenzene-1,2-diamine (-CAN) on TiO was revealed, contributing to selective C-N coupling rather than dechlorination.

In the present study, confocal laser scanning fluorescence microscopy observation demonstrated these three natural OAs could traverse inside of the nucleus and get an opportunity to interact with DNA. Their interaction properties with DNA were then investigated simultaneously by two spectral fluorescent probes of ethidium bromide (EB) and methyl green (MG), as well as UV-vis absorption and cyclic voltammetry measurements, and further verified by the molecular docking analysis.
