Active site-directed inhibition of E. coli DNA-dependent RNA polymerase by pyridoxal 5′-phosphate

open access: yes, 1973
peer reviewedDNA-dependent RNA polymerase from E. coli is rapidly inhibited by preincubation with pyridoxal 5′-phosphate. The enzyme is not inhibited by pyridoxamine 5′-phosphate or pyridoxine. Pyridoxal is about 10 times less effective than pyridoxal 5′-

Comprehensive Peptide Profiling Reveals the Influence of Streptococcus Thermophilus, Lactobacillus Delbrueckii Subsp. bulgaricus, and Endogenous Milk Proteases on the Hydrolysis of Milk Proteins During Early‐Stage Lactic Acid Fermentation

open access: yesChemFoodChem, Volume 2, Issue 3, September 2026.
Untargeted peptide profiling investigates how S. thermophilus, Lb. bulgaricus, and endogenous milk enzymes impact proteolysis during early‐stage milk fermentation. ≥ 3000 identified peptides show the strongest influence of LB on the peptide profile and number of bioactive peptides. Shorter peptides are mostly formed by LB and hydrolyzed by ST.

Systemic Inflammation and Subclinical Hepatic Synthetic Dysfunction Following Doxorubicin‐Cyclophosphamide Chemotherapy in Ethiopian Women With Breast Cancer: A Prospective Cohort Study

open access: yesHealth Science Reports, Volume 9, Issue 9, September 2026.
ABSTRACT Background and Aims Doxorubicin‐cyclophosphamide (AC) chemotherapy induces hepatotoxicity through oxidative stress and inflammatory pathway activation, but prospective African data are lacking and conventional liver tests may miss subclinical injury.

Iron‐Sulfur Cluster Targeting: A Novel Perspective for Treating Alcohol‐Related Lipid Metabolic Diseases

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 9, September 2026.
Alcohol metabolism induces structural instability of iron‐sulfur clusters through ROS‐mediated oxidative damage and direct covalent modification of acetaldehyde. The iron‐sulfur cluster deficiency drives metabolic reprogramming by inactivating aconitase, accumulating succinate, and impairing tRNA thiolation, thereby promoting hepatic steatosis ...

Inhibition of Tropomyosin Receptor Kinase B Signaling Alters Hepatic Mitochondrial Enzyme Activity and Oxidative Stress in Mice With Sucrose‐Induced Insulin Resistance

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 9, September 2026.
Suppression of BDNF‐TrkB signaling has shown a protective trend on hepatic oxidative stress by reducing sucrose‐induced lipid peroxidation. BDNF–TrkB signaling pathway plays a peripheral role in regulating mitochondrial enzyme capacity and redox balance in the liver.

Living Biohybrid Hydrogels for Co‐Delivery of Oxygen, Anti‐Cancer Drugs, and Probiotics: Effects on Cancer and Healthy Cell Viability

open access: yesMacromolecular Bioscience, Volume 26, Issue 9, September 2026.
A probiotic‐enriched BioHybrid hydrogel that provides sustained O2, probiotic metabolites, and pH‐responsive anti‐cancer drug is reported. This BioHybrid hydrogel promotes healthy cell viability while reducing ROS and decreases cancer cell viability while increasing ROS under hypoxia conditions. The co‐administration of O2, metabolites, and drug from a

Ergothioneine: Biosynthesis, Molecular Mechanisms, Physiological Function, and Role in Disease

open access: yesMedComm, Volume 7, Issue 9, September 2026.
Ergothioneine is a natural thione antioxidant with significant biomedical potential. By reducing oxidative stress, inflammation, mitochondrial dysfunction, and cellular injury, ergothioneine may support interventions for aging‐related disorders, neurodegeneration, metabolic diseases, and skin protection.

Pyridoxal Phosphate-Responsive Epilepsy with Resistance to Pyridoxine

open access: yes, 2009
We present a female infant with seizures responsive to pyridoxal phosphate but that are resistant to pyridoxine. The mechanism by which pyridoxal phosphate controls seizures in this patient is unknown.

Mechanistic Insights Into Hepatotoxicity‐Induced Liver Cirrhosis and Anemia: Iron Dysregulation, the Hepcidin–Ferroportin Axis, and Emerging Therapeutic Strategies

open access: yesOrgan Medicine, Volume 3, Issue 3, Page 171-185, September 2026.
Patients with alcohol‐associated liver cirrhosis or acetaminophen (APAP) toxicity frequently develop anemia with iron metabolism disturbances. Dysregulation of hepcidin–ferroportin signaling, along with inflammation, oxidative stress, hypoxia, impaired intestinal iron absorption, malnutrition, and gastrointestinal bleeding, contributes to anemia ...

Genetic Tools in the Nakaseomyces clade for Evolutionary Comparisons of Signal Transduction Pathways

open access: yesYeast, Volume 43, Issue 5, Page 202-213, September 2026.
ABSTRACT The genus Nakaseomyces provides four species that are closely related but have different characteristics. For example, N. glabratus (formerly known as Candida glabrata) is a common human pathogen, whereas N. bracarensis and N. nivariensis have been isolated in clinical settings but are not common human pathogens. N.
