Alternative splicing drives a dynamic transcriptomic response during Acanthamoeba castellanii programmed cell death

August 25, 2025

Programmed cell death (PCD) in unicellular organisms is not well characterized. This study investigated the transcriptomic response of Acanthamoeba castellanii to G418-induced PCD, focusing on the role of alternative splicing (AS). RNA sequencing revealed extensive transcriptional changes, affecting approximately 70% of annotated genes over six hours of treatment.

Gut microbiota and ankylosing spondylitis: current insights and future challenges

August 25, 2025

This review explores the growing role of gut microbiota in AS and its potential to reshape targeted treatment strategies and facilitate development of adjunct therapies to address disease onset and progression.

Role of the putative sit1 gene in normal germination of spores and virulence of the Mucor lusitanicus

August 12, 2025

Mucormycosis is a life-threatening infection caused by certain members of the fungal order Mucorales, with increased incidence in recent years. Individuals with untreated diabetes mellitus, and patients treated with deferoxamine are particularly susceptible to this infection.

Tumor microenvironment signatures enhances lung adenocarcinoma prognosis prediction: Implication of intratumoral microbiota

August 11, 2025

The interaction between intratumoral microbiome and the tumor microenvironment (TME) has furthered our understanding of tumor ecology. Yet, the implications of their interaction for lung cancer management remain unclear.

Persistence phenotype of adherent-invasive Escherichia coli in response to ciprofloxacin, revealing high-persistence strains

July 11, 2025

We investigated the roles of the resident antibiotic resistance plasmid, the stress response protein HtrA, and macrophage-induced persister formation. Our results revealed broad variability in persister cell formation among AIEC strains.

Knocking out histidine ammonia-lyase by using CRISPR-Cas9 abolishes histidine role in the bioenergetics and the life cycle of Trypanosoma cruzi

June 25, 2025

Recent studies have highlighted the importance of this pathway in ATP production, redox balance, and the maintenance of cellular homeostasis in T. cruzi. In this work, we focus on the first step of the histidine degradation pathway, which is performed by the enzyme histidine ammonia lyase. Here we determined the kinetic and biochemical parameters of the T. cruzi histidine ammonia-lyase.

Dissecting the cell cycle regulation, DNA damage sensitivity and lifespan effects of caffeine in fission yeast

June 24, 2025

Our findings show that caffeine accelerates mitotic division and is beneficial for CLS through AMPK. Direct pharmacological targeting of AMPK may serve towards healthspan and lifespan benefits beyond yeasts, given the highly conserved nature of this key regulatory cellular energy sensor.

Uga3 influences nitrogen metabolism in Saccharomyces cerevisiae by modulating arginine biosynthesis

June 12, 2025

Nitrogen metabolism in Saccharomyces cerevisiae is tightly regulated to optimize the utilization of available nitrogen sources. Uga3 is a known transcription factor involved in the gamma-aminobutyric acid (GABA) pathway; however, its broader role in nitrogen metabolism remains unclear.

An adenine model of inborn metabolism errors alters TDP-43 aggregation and reduces its toxicity in yeast revealing insights into protein misfolding diseases

May 22, 2025

This work offers new insights into the potential interactions between me-tabolite-based amyloids and pathological protein aggregates, with broad implications for understanding protein misfolding diseases.

Advancements in vaginal microbiota, Trichomonas vaginalis, and vaginal cell interactions: Insights from co-culture assays

May 15, 2025

This review updates co-culture and co-incubation techniques for studying interactions of Lactobacillus spp., representing a pre-dominant member of the healthy vaginal microbiota; Candida spp., the most abundant yeast in the vagina, and T. vaginalis, responsible for the most widespread nonviral STI worldwide.
