Polypropylene Nanoplastic Exposure to Respiratory Epithelial Barrier‐On‐Chip and Interfacial Interactions With Human Serum Albumin

open access: yesAllergy, EarlyView.
Exposure to 305 nm PP NPs significantly disrupts the airway barrier‐on‐chip, reducing TEER, suppressing ZO‐1/ACE2 expression, and triggering ROS‐mediated apoptosis. In biological media, PP NPs exhibit a biphasic adsorption pattern, leading to the formation of a protein corona that increases their size to 364 nm.

Die Funktion des Responseregulators ARR2 in der Entwicklung von Arabidopsis thaliana [PDF]

open access: yes, 2004
In dieser Arbeit konnte mittels physiologischer Experimente, Expressionsanalysen, Phosphorylierungsassays und Transaktivierungsanalysen eine komplexe Funktion von ARR2 in verschiedenen Signaltransduktionswegen von Arabidopsis aufgedeckt werden.

Dual pharmacological targeting of coactivator‐associated arginine methyltransferase 1 (CARM1) and salt inducible kinase (SIK) drives ketogenesis in both hepatocytes and mice

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ketone bodies are liver‐derived circulating energy metabolites that positively impact most hallmarks of ageing. Ketone bodies increase during calorie restriction and fasting, two of the more widely perceived methods to increase health span.

Retinoic Acid Signalling Regulates Zebrafish Tooth Germ Repair Following Injury

open access: yesCell Proliferation, EarlyView.
Retinoic acid signalling may regulate the repair processes in a tooth germ injury model using Tg(scpp5:Dendra2‐NTR) zebrafish and the nitroreductase (NTR)/metronidazole (MTZ) system. ABSTRACT Although the role of retinoic acid (RA) signalling in odontogenesis is well established, its involvement in the repair of injured tooth germs remains unclear.

Inositol and Berberine Synergistically Reprogram Endocrine and Ovarian Metabolism in Polycystic Ovary Syndrome

open access: yesCell Proliferation, EarlyView.
In a DHEA+HFD‐induced mouse model, Ins/BBR alleviated mitochondrial defects and broadly reprogrammed metabolic landscape in granulosa cells, in specific, restoring nucleotide pools and amino acid turnover, and preventing abnormal long‐chain fatty acid accumulation.

Evaluation of the molecular mechanism underlying proline metabolic and catabolic pathways and some morpho-physiological traits of tobacco (Nicotiana tabacum L.) plants under arsenic stress

open access: yesBMC Plant Biology
Background In recent decades, arsenic (As) toxicity has emerged as a significant challenge in many countries. It not only reduces the growth and performance of plants, but also poses a threat to human health.

Oxygen‐independent expression of HIF‐1α during the cell cycle in hepatocellular carcinoma cells controls essential metabolic pathways under normoxia

open access: yesThe FEBS Journal, EarlyView.
In Huh7 cells, HIF‐1α is essential as it maintains the expression of proteins involved in glycolysis and steroid/cholesterol biosynthesis both under normoxia and hypoxia. On the other hand, in HeLa cells, these pathways are induced by HIF‐1α only under hypoxia.

Stronger inflammatory/cytotoxic T cell response in women identified by microarray analysis [PDF]

open access: yes, 2008
Women develop chronic inflammatory autoimmune diseases like lupus more often than men. The mechanisms causing the increased susceptibility are incompletely understood, although estrogen is believed to contribute.

Steroidogenic compensation and lipid deficiency with enhanced NAD+ salvage in small‐for‐gestational‐age placenta

open access: yesThe FEBS Journal, EarlyView.
Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.
