The Double Face of Base Excision Repair: Preventing and Triggering Double‐Strand Breaks

BioEssays, Volume 48, Issue 1, January 2026.
Base excision repair is conserved from bacteria to man, robustly eliminating oxidized bases in DNA and reinserting the appropriate nucleotide to restore an intact double helix. Recent results describe conditions and mechanisms that misregulate long‐patch BER to generate double‐strand breaks, triggering chromosome fragmentation and cell death, altering ...

Proteomic and Ubiquitinated Proteome Insights Into ER Stress Responses in Chinese Hamster Ovary Cells Under Mild Hypothermic Conditions

Biotechnology and Bioengineering, Volume 123, Issue 1, Page 5-25, January 2026.
Proteomic analysis of CHO cells under mild hypothermia (31°C) reveals ER stress responses, ubiquitination dynamics, and adaptive mechanisms. Magnetic immuno‐affinity enrichment and mass spectrometry highlight protein regulation differences in non‐producer versus producer cells, offering insights for optimising biopharmaceutical production of IgG1 and ...

Bifidobacterium longum subsp. longum CCFM1375 Mitigates Chronic Kidney Disease Progression via Gut Microbiota Modulation and Gut Barrier Restoration

Food Frontiers, Volume 7, Issue 1, January 2026.
(1) Bifidobacterium longum subsp. longum CCFM1375 restored gut barrier integrity by upregulating ZO‐1/ZO‐2 and suppressing IL‐6/TNF‐α, thereby reducing serum LPS and improving creatinine/BUN levels. (2) Reshaped gut microbiota: enriched beneficial species (Faecalibaculum rodentium, Asaccharobacter celatus, Adlercreutzia equolifaciens) while suppressing

Integrative Evidence From Metabolome‐Wide Mendelian Randomization and Animal Models Implicates Tyrosine in Cardiac Hypercontractility and Arrhythmia Risk

Food Frontiers, Volume 7, Issue 1, January 2026.
Plasma metabolome‐wide Mendelian randomization analysis established a causal link between tyrosine and arrhythmia. GWAS meta‐analysis identified tyrosine‐associated loci linked to cardiovascular risk factors. Animal studies confirmed that oral tyrosine intake modulates heart rhythm via adrenergic signaling activation.

High‐Dose Parenteral Iron Corrects Iron Deficiency Anemia While Disrupting Gut Microbiota and Metabolic Homeostasis in Neonatal Piglets

Food Frontiers, Volume 7, Issue 1, January 2026.
Our results indicate that although high‐dose parenteral iron effectively corrects iron deficiency anemia (IDA), it causes liver dysfunction, immune suppression, systemic iron overload, and altered gut microbiota. ABSTRACT Iron deficiency anemia (IDA) is a common nutritional disorder in mammals, particularly affecting neonates and neonatal piglets ...

Novel nanoparticle‐mediated plasmid delivery in bacteria for difficult applications

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 1, Page 123-134, January 2026.
Abstract BACKGROUND This study presents the development and application of magnetite/silver‐pDMAEMA‐PEG‐BUFII nanobioconjugates as an advanced plasmid delivery system in bacteria. These nanobioconjugates demonstrated superior efficiency compared to traditional methods in four challenging applications: (i) genomic editing in Gram‐positive bacteria; (ii)
