AI Article Synopsis

  • * The review highlights the significance of microRNAs found in MSC-derived EVs (the EV microRNAome) and their role in the therapeutic effects of these treatments.
  • * Despite compelling evidence of the effectiveness of miRNA transfer, there are unresolved issues about their low quantities, interactions with target cells, and the identification of optimal miRNA therapies and biomarkers for clinical use.

Article Abstract

Mesenchymal stromal cells (MSCs) and MSC-derived extracellular vesicles (EVs) have emerged as innovative therapeutic agents for the treatment of sepsis and acute respiratory distress syndrome (ARDS). Although their potential remains undisputed in pre-clinical models, this has yet to be translated to the clinic. In this review, we focused on the role of microRNAs contained in MSC-derived EVs, the EV microRNAome, and their potential contribution to therapeutic mechanisms of action. The evidence that miRNA transfer in MSC-derived EVs has a role in the overall therapeutic effects is compelling. However, several questions remain regarding how to reconcile the stochiometric issue of the low copy numbers of the miRNAs present in the EV particles, how different miRNAs delivered simultaneously interact with their targets within recipient cells, and the best miRNA or combination of miRNAs to use as therapy, potency markers, and biomarkers of efficacy in the clinic. Here, we offer a molecular genetics and systems biology perspective on the function of EV microRNAs, their contribution to mechanisms of action, and their therapeutic potential.

Anxiolytic-like Effect of Chrysin on Female Zebrafish is Likely Mediated by α5 subunits of GABAA Receptors.

Chem Biodivers

UNIFESSPA: Universidade Federal do Sul e Sudeste do Para, Faculdade de Psicologia, Rod. BR-230 (Transamazônica), Loteamento Cidade Jardim, Av. dos Ipês, s/n.º - Ci, 68503000, Marabá, BRAZIL.

Chrysin (5,7-dihydroxyflavone) is a natural flavonoid with potential anxiolytic-like effects in preclinical models. Acute treatment with this molecule (0 - 10 mg/kg) produced a biphasic dose-response in the zebrafish light/dark test (LDT), with anxiolytic-like effect at low doses and anxiogenic-like effects at high doses. Chrysin (1 mg/kg) decreased anxiety-like behavior in the zebrafish novel tank test (NTT), but did not prevent the anxiogenic effects of acute stress.

Catheter-associated urinary tract infections (CAUTIs), often caused by biofilm-forming Staphylococcus aureus, present significant clinical challenges. Skt35, a dioxopiperidinamide derivative of cinnamic acid, was investigated for its potential antibacterial and antibiofilm activities against S. aureus biofilms.

Responses of biological characteristics and detoxification enzymes in the fall armyworm to methoxyfenozide stress.

J Econ Entomol

January 2025

Hubei Engineering Technology Center of Forewarning and Management of Agricultural and Forestry Pests, Yangtze University, Jingzhou 434000, PR China.

Methoxyfenozide is an insecticide with a unique mode of action on the insect ecdysone receptor and has been registered for the control of insect pests all over the world. In the present work, Spodoptera frugiperda was exposed to sublethal and lethal concentrations of methoxyfenozide to determine its impact on specific biological traits, metabolic enzyme activity, and the expression of detoxification enzymes. The result showed that 72-h posttreatment with LC50 and LC70 of methoxyfenozide significantly reduced the fecundity (eggs/female) of the F0 generation compared to those of the control group.

The Orange Carotenoid Protein (OCP) is a unique water-soluble photoactive protein that plays a critical role in regulating the balance between light harvesting and photoprotective responses in cyanobacteria. The challenge in understanding OCP´s photoactivation mechanism stems from the heterogeneity of the initial configurations of its embedded ketocarotenoid, which in the dark-adapted state can form up to two hydrogen bonds to critical amino acids in the protein's C-terminal domain, and the extremely low quantum yield of primary photoproduct formation. While a series of experiments involving point mutations within these contacts helped us to identify these challenges, they did not resolve them.

Synthesis and evaluation of the antifungal and antibiofilm potential of aminochalcones.

Arch Microbiol

January 2025

Department of Chemistryand Environmental Sciences, Institute of Biosciences, Humanities and Exact Sciences, São Paulo State University Júlio de Mesquita Filho, São José do Rio Preto, SP, Brazil.

Candida is a commensal fungus of clinical interest that commonly lives in oral cavity and intestine but can become an opportunist microrganism and cause severe infections. A serie of 10 aminochalcones were designed and synthetized to obtain compounds anti-Candida with potent and broad-spectrum activity. The most active compound J34 demonstrated excellent in vitro activity against Candida albicans, Candida tropicalis, Candida parapsilosis, Candida glabrata and Candida krusei with minimum inhibitory concentration between 1.
