Melanoma, a highly aggressive skin cancer, continues to challenge current therapeutic modalities due to its resistance and high mortality rates. Recent advancements highlight cuproptosis, a copper-driven form of programmed cell death, as a promising target for melanoma treatment. This study integrated machine learning and large-scale genomic data to identify FDX1 as a pivotal gene in cuproptosis-related pathways for melanoma.

This study investigates the therapeutic potential of Clostridium butyricum for modulating the inflammatory cascade through the AMPK/NF-κB signaling pathway, focusing on inflammation induced by AP. LC-MS analysis of serum samples from AP patients highlighted the regulation of lipid metabolism and inflammation, and found that metabolites involved in the inhibition of NF-κB phosphorylation and the AMPK activation pathway were downregulated.
View Article and Find Full Text PDFAcute pancreatitis frequently causes intestinal barrier damage, which aggravates pancreatitis. Although Clostridium butyricum exerts anti-inflammatory and protective effects on the intestinal barrier during acute pancreatitis, the underlying mechanism is unclear. The G protein-coupled receptors 109 A (GPR109A) and adenosine monophosphate-activated protein kinase (AMPK)/ peroxisome proliferator-activated receptor-gamma coactivator 1 alpha (PGC-1α) signaling pathways can potentially influence the integrity of the intestinal barrier.

The gut microbiota and its metabolites play an important role in SAP development and may provide new targets for AP-associated lung injury. Based on the ability to reverse AP injury, we proposed that Clostridium butyricum may reduce the potential for AP-associated lung injury by modulating with intestinal microbiota and related metabolic pathways.

Stress response stated T cells (Tstr) are a new T-cell subtype, which are related to poor disease stage and immunotherapy response in various cancers.
Methods: 10 machine-learning algorithms and their combinations were applied in this work.
Evidence have shown that gut microbiota plays an important role in the development of severe acute pancreatitis (SAP). In addition, matrix metalloproteinase-9 (MMP9) plays an important role in intestinal injury in SAP. Thus, we aimed to determine whether gut microbiota could regulate the intestinal injury during SAP modulating MMP9.

Heavy chain single domain antibodies have promising prospects as therapeutic antibodies. A bispecific nanobody was constructed based on previously screened humanized nanobodies that target the β-loop at the EGFR dimer interface, an anti-FcγRIIIa (CD16) of natural killer cells (NK) nanobodies and anti-human serum albumin (HSA) nanobodies.

Objective To express, purify and identify the single-chain fragment variable (scFv) against human epidermal growth factor receptor 3 (HER3). Methods We searched NCBI for the light chain sequence and heavy chain sequence of anti-HER3 mAb LJM716 to construct the gene of scFv against HER3. The recombinant expression vector pGAPZαA-anit-HER3-scFv was constructed using the constitutive expression vector pGAPZαA and then electro-transformed into Pichia Pastoris X-33 to screen the strains with high expression of the protein of interest.

To validate this strategy, the interaction interface between PD-1 and the PD-L1 extracellular domain were analyzed using Cn3D 4.1.
View Article and Find Full Text PDFEpidermal growth factor receptor (EGFR) is an effective target for the treatment of many epithelial cancers. However, EGFR inhibitors have low clinical response rates and are prone to drug resistance arising from mutations and heterodimerization of EGFR. Therefore, targeting the highly conserved dimer interface of EGFR may be an effective strategy for improving the clinical response of anti-EGFR therapies.

It is now recognized that the high infection rates were caused by the formation of biofilm on the surface of the catheters that decreases the susceptibility to antibiotics and results in anti-microbial resistance.In this study, we performed an in vitro test to explore the mechanism of biofilm formation and subsequently conducted a multi-center clinical trial to investigate the efficacy of CAUTI prevention with the application of JUC, a nanotechnology antimicrobial spray.
