Lung Cancer Patients Display Increased Expression of Bovine Meat and Milk Factor (BMMF) Proteins in Peritumor Alveolar Macrophages

International Journal of Cancer, EarlyView.
Plasmid‐like DNA sequences frequently found in bovine milk and serum have been proposed as infectious agents promoting indirect carcinogenesis. This multi‐omics study detected immune cells positive for these bovine meat and milk factors (BMMFs) in patients with lung cancer, with BMMF expression inversely correlated with smoking intensity.

Genetically dissecting the electron transport chain of a soil bacterium reveals a generalizable mechanism for biological phenazine-1-carboxylic acid oxidation.

PLoS Genetics
The capacity for bacterial extracellular electron transfer via secreted metabolites is widespread in natural, clinical, and industrial environments. Recently, we discovered the biological oxidation of phenazine-1-carboxylic acid (PCA), the first example ...

Nitrate reduction by salivary bacteria, glucose metabolism, and lifestyle

Journal of Oral Microbiology
Background Nitrate reductases (NR) expressed in oral bacteria reduce nitrate to nitrite. Depending on the environmental conditions and types of bacteria present nitrite can be further reduced to ammonium via Dissimilatory Nitrate Reduction to Ammonium ...

Predictive Biomarkers in Metastatic Colorectal Cancer Patients Treated With Bevacizumab: A Turkish Oncology Group (TOG) Study

International Journal of Cancer, EarlyView.
Bevacizumab added to systemic chemotherapy remains a cornerstone of metastatic colorectal cancer treatment, but its effectiveness is variable. Tumors can bypass the VEGF blockade by activating other pro‐angiogenic pathways, hampering the identification of predictive biomarkers.

Microbiome‐mediated plant‐soil feedbacks as a tool for resilient agriculture

iMetaOmics, EarlyView.
Translating plant‐soil feedbacks (PSFs) into reliable agricultural management requires shifting from input‐dependent practices toward endogenous, process‐driven crop resilience. To bridge this gap, we propose a predictive framework centered on three strategic interventions: engineering the crop holobiont, diversifying the soil habitat, and deploying ...

Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

Journal of the Chinese Chemical Society, EarlyView.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...
