The Highly Conserved Cys95 Residue of Fructose‐1,6‐Bisphosphatase 1 Mediates the pH‐Driven Structure and Activity of the Enzyme and Photosynthesis

Plant, Cell &Environment, Volume 48, Issue 9, Page 6941-6951, September 2025.
ABSTRACT In Arabidopsis, exposure to microbial volatile compounds promotes thiol reduction of the Cys95 residue of the photosynthetic enzyme fructose‐1,6‐bisphosphatase (cFBP1). Although highly conserved in plants, the Cys95 function still remains unknown. We characterised recombinant wild‐type (WT) cFBP1 and a variant (C95S) in which the Cys95 residue

Spontaneous and pharmacologically induced hypothermia protect mice against endotoxic shock

British Journal of Pharmacology, Volume 182, Issue 12, Page 2621-2641, June 2025.
Background and Purpose Despite the well‐known occurrence of hypothermia during sepsis, its underlying biological nature and adaptive value remain debated. Experimental Approach Using indirect calorimetry, telemetry, thermal gradient studies and pharmacological studies, we examined the thermal and metabolic responses of mice treated with a shock ...

Thiol-based redox control of enzymes involved in the tetrapyrrole biosynthesis pathway

Frontiers in Plant Science, 2013
The last decades of research brought substantial insights into tetrapyrrole biosynthetic pathway in photosynthetic organisms. Almost all genes have been identified and roles of seemingly all essential proteins, leading to the synthesis of heme, siroheme,

Threonine and tyrosine kinase (TTK) mRNA and protein expression in breast cancer; prognostic significance in the neoadjuvant setting

Histopathology, Volume 86, Issue 6, Page 916-932, May 2025.
This study investigates threonine and tyrosine kinase (TTK) expression in pre‐ and post‐neoadjuvant chemotherapy breast cancer patients. TTK mRNA expression was elevated in breast cancer tissues, predicting reduced survival. Notably, TTK protein expression in neoadjuvant chemotherapy‐treated breast cancer patients was up‐regulated post‐therapy and ...

Nitrogen Assimilation Plays a Role in Balancing the Chloroplastic Glutathione Redox Potential Under High Light Conditions

Plant, Cell &Environment, Volume 48, Issue 5, Page 3559-3572, May 2025.
ABSTRACT Nitrate reduction requires reducing equivalents produced by the photosynthetic electron transport chain. Therefore, it has been suggested that nitrate assimilation provides a sink for electrons under high light conditions. We tested this hypothesis by monitoring photosynthetic efficiency and the chloroplastic glutathione redox potential (chl ...

Regulatory and retrograde signaling networks in the chlorophyll biosynthetic pathway

Journal of Integrative Plant Biology, Volume 67, Issue 4, Page 887-911, April 2025.
This review summarizes the regulatory mechanisms that underlie chlorophyll synthesis, including (1) factors that control the activity and stability of tetrapyrrole biosynthesis enzymes, (2) transcriptional and post‐translational regulation of the tetrapyrrole biosynthesis pathway, and (3) the complex roles of tetrapyrrole‐mediated retrograde signaling ...

Cellodextrin Metabolism and Phosphotransferase System‐Catalyzed Uptake in Enterococcus faecalis

Molecular Microbiology, Volume 123, Issue 4, Page 378-391, April 2025.
In an infectious context, β‐glucoside metabolism is highly induced in Enterococcus faecalis. Our work demonstrates that this bacterium possesses a network of multiple PTS transporters dedicated to the transport of cellobiose and cellodextrins. The genes encoding the proteins involved in this metabolism are clustered within a single locus in the E ...

Broad spectrum pro-quorum-sensing molecules as inhibitors of virulence in vibrios.

PLoS Pathogens, 2012
Quorum sensing (QS) is a bacterial cell-cell communication process that relies on the production and detection of extracellular signal molecules called autoinducers. QS allows bacteria to perform collective activities.
