A Dual‐Targeting T6SS DNase Drives Bacterial Antagonism and Eukaryotic Apoptosis via the cGAS‐STING‐TNF Axis

Advanced Science, EarlyView.
The bacterial Type VI secretion system (T6SS) emerges as a sophisticated virulence mechanism, leveraging the dual‐function effector TkeA from Yersinia pseudotuberculosis. TkeA concurrently damages rival bacteria and host cell DNA, triggering the host's cGAS‐STING‐TNF pathway and inducing apoptosis.

Development of Simple Sequence Repeat Markers from Bacterial Artificial Chromosomes without Subcloning

BioTechniques, 2001
Simple sequence repeats (SSRs) were isolated from pearl millet bacterial artificial clones (BACs) without any subcloning steps. SSR sequences were targeted using 3′ end anchored SSR primers. Flanking sequences were isolated by suppression PCR.

High‐Throughput Tiling of Essential mRNAs Increases Potency of Antisense Antibiotics

Advanced Science, EarlyView.
The systematic tiling of essential genes’ mRNA here presented, proposes a valuable tool for the identification of novel PNA sequences with antibiotic potential. The high‐throughput synthetic set up opens the door to investigating thousands of sequences in an economic way and ultimately identifies potent antisense oligonucleotides while also giving room

Microbial Biosensor for Sensing and Treatment of Intestinal Inflammation

Advanced Science, EarlyView.
The engineered calprotectin biosensor detects gut inflammation, processes the signal through genetic regulation, and responds by expressing the reporter sfGFP and the therapeutic protein secIL10. This dual functionality enables the engineered biosensor not only to sense but also to mitigate gut inflammation, highlighting its potential for disease ...

MatP regulates the coordinated action of topoisomerase IV and MukBEF in chromosome segregation

Nature Communications, 2016
MukBEF, the bacterial structural maintenance of chromosomes complex, is known to associate with origins of replication and topoisomerase IV. Here the authors show an association of MukBEF with MatP and replication termination regions, important for ...

UTX Responds to Nanotopography to Suppress Macrophage Inflammatory Response by Remodeling H3K27me3 Modification

Advanced Science, EarlyView.
Compared with those on the pTi surface, macrophages on the TNTs surface present reduced myosin II contractility, which facilitates the nuclear translocation of the UTX. This reduction decreases the enrichment of the repressive H3K27me3 histone modification at the Abca1 gene locus, which promotes the transcription and protein expression of ABCA1 ...

Mycosis Fungoides, Sézary Syndrome, and Cutaneous B‐Cell Lymphomas: 2025 Update on Diagnosis, Risk‐Stratification, and Management

American Journal of Hematology, EarlyView.
ABSTRACT Disease Overview Primary cutaneous lymphomas are a rare and heterogeneous group of extranodal lymphomas that require the integration of clinical and histopathologic data for classification and treatment. Diagnosis Diagnosis and disease classification is based on histopathologic review and immunohistochemical staining of an appropriate skin ...

A conserved mechanism drives partition complex assembly on bacterial chromosomes and plasmids

Molecular Systems Biology, 2018
Chromosome and plasmid segregation in bacteria are mostly driven by ParABS systems. These DNA partitioning machineries rely on large nucleoprotein complexes assembled on centromere sites (parS).

Worth the Effort: Lessons for Discovery and Care From an Unusual Case of Gorlin Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Gorlin‐Goltz Syndrome (GGS) is a rare autosomal dominant genetic disorder encompassing a diverse range of clinical manifestations, including congenital anomalies and predisposition to cancer. Pathogenic variants in PTCH1 and SUFU account for up to 79% and 6% of cases, respectively. Currently, an estimated 15%–27% of individuals with a clinical
