Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Genetic clusteringof KPC-2-producing carbapenem-resistant Klebsiella pneumoniae ST5422-KL19 in Shanghai, China

BMC Microbiology
The globally disseminated high-risk CRKP clone ST5422, though frequently harboring multiple carbapenemase genes, exhibits only sporadic occurrence in China. We report a Shanghai genetic clustering involving seven ST5422 CRKP isolates harboring bla KPC-2.

Emergence and characterization of new OXA-181 variants in France: OXA-1181, OXA-1201, OXA-1205, OXA-1207, and OXA-1226

Microbiology Spectrum
Since 2022, the diversity of OXA-48 variants has increased in France. We analyzed the dissemination of five recent variants (OXA-1181, OXA-1201, OXA-1205, OXA-1207, and OXA-1226) mostly identified on plasmids in high-risk Escherichia coli clones.

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

Molecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...

Whole-genome characterisation of high-risk ST131 and the emerging ST1193 UPEC lineages in Romanian patients with recurrent urinary tract infections

Frontiers in Microbiology
Recurrent urinary tract infections (UTIs) are frequently associated with persistent uropathogenic Escherichia coli (UPEC) lineages that combine antimicrobial resistance with virulence traits, contributing to treatment failure. Whole-genome sequencing was

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...
