Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Histidine Phosphorylation: Protein Kinases and Phosphatases

open access: yesInternational Journal of Molecular Sciences
Phosphohistidine (pHis) is a reversible protein post-translational modification (PTM) that is currently poorly understood. The P-N bond in pHis is heat and acid-sensitive, making it more challenging to study than the canonical phosphoamino acids pSer, pThr, and pTyr. As advancements in the development of tools to study pHis have been made, the roles of

Genistein inhibits protein histidine kinase.

open access: yesJournal of Biological Chemistry, 1992
Protein histidine kinase was prepared from whole cell extracts of the yeast, Saccharomyces cerevisiae. The enzyme was assayed using either histone H4 or a synthetic peptide corresponding to residues 70 to 102 of histone H4 as an in vitro substrate. With either substrate, both genistein and its solvent, dimethyl sulfoxide (Me2SO), inhibited protein ...

Engineered Exosome‐Based Senolytic Therapy Alleviates Stroke by Targeting p21+CD86+ Microglia

open access: yesExploration, EarlyView.
We identified a harmful immune cell type, p21+CD86+ microglia, driving post‐stroke inflammation and developed a targeted exosome‐based therapy (Que@micro‐Exo) to eliminate these cells. This innovative treatment reduced inflammation, alleviated brain damage, and improved recovery in stroke models, offering a promising strategy for stroke and other ...

Segmental helical motions and dynamical asymmetry modulate histidine kinase autophosphorylation.

open access: yesPLoS Biology, 2014
Histidine kinases (HKs) are dimeric receptors that participate in most adaptive responses to environmental changes in prokaryotes. Although it is well established that stimulus perception triggers autophosphorylation in many HKs, little is known on how ...

The cyclic AMP phosphodiesterase RegA critically regulates encystation in social and pathogenic amoebas [PDF]

open access: yes, 2014
Amoebas survive environmental stress by differentiating into encapsulated cysts. As cysts, pathogenic amoebas resist antibiotics, which particularly counteracts treatment of vision-destroying Acanthamoeba keratitis. Limited genetic tractability of amoeba

An investigation into the transcription factors and regulatory mechanisms of Aspergillus

open access: yesFood Safety and Health, EarlyView.
Foodborne pathogen Aspergillus, a prevalent etiologic agent among filamentous fungi, are distinguished by a significant repertoire of transcription factors encoded within their genomes. These regulatory proteins are instrumental in orchestrating key biological processes, including cellular growth, secondary metabolite biosynthesis, mycotoxin production,
