Candidate Biomarker of Response to Immunotherapy In Small Cell Lung Cancer.

Small-cell lung cancer accounts for about 15% of lung cancers with an extremely poor prognosis. The incorporation of immunotherapy to platinum-based chemotherapy offers sustained overall survival benefits and become the standard for the first-line setting of extensive-stage small-cell lung cancer. However, only a limited number of patients derive prolonged benefits.

Targeting MAPK14 by Lobeline Upregulates Slurp1-Mediated Inhibition of Alternative Activation of TAM and Retards Colorectal Cancer Growth.

Colorectal cancer (CRC) usually creates an immunosuppressive microenvironment, thereby hindering immunotherapy response. Effective treatment options remain elusive. Using scRNA-seq analysis in a tumor-bearing murine model, it is found that lobeline, an alkaloid from the herbal medicine lobelia, promotes polarization of tumor-associated macrophages (TAMs) toward M1-like TAMs while inhibiting their polarization toward M2-like TAMs.

A novel interplay between bacteria and metabolites in different early-stage lung cancer: an integrated microbiome and metabolome analysis.

Background: The carcinogenesis mechanism of early-stage lung cancer (ESLC) remains unclear. Microbial dysbiosis is closely related to tumor development. This study aimed to analyze the relationship between microbiota dysbiosis in ESLC.

Association between Ambient Ultrafine Particles and Neurodevelopmental Delay in Preschoolers in Shanghai, China.

Previous toxicological research has suggested the potential neurotoxicity of ultrafine particulate matter (UFP, particles ≤0.1 μm in diameter). However, evidence from human beings, particularly regarding the neurodevelopmental impacts of UFP, is still limited.

Intervertebral Disc Degeneration Mediates the Causal Effect of Genetically Predicted Diffuse Idiopathic Skeletal Hyperostosis on Spinal Stenosis: Evidence From a Mendelian Randomization Study.

Background: Previous studies have noted an association between diffuse idiopathic skeletal hyperostosis (DISH) and spinal stenosis (SS), although causation is unclear. This study used Mendelian randomization (MR) to investigate the causal relationship between the two.

Methods: We utilized large GWAS datasets on DISH and SS to perform a two-sample, bidirectional MR analysis, also quantifying the mediating role of intervertebral disc degeneration (IDD).
