TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics

The FEBS Journal, EarlyView.
This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...

Clonal Hematopoiesis and CAR T Cell Therapy: From Biological Crosstalk to Clinical Implications

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Clonal hematopoiesis (CH) is increasingly recognized as a significant biological phenomenon in aging and cancer, marked by the expansion of hematopoietic stem and progenitor cells harboring somatic mutations in genes associated with myeloid neoplasms.

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

Cell‐Specific Expression and Cellular Compartmental Regulation in Camptothecin Biosynthesis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant secondary metabolites such as monoterpenoid indole alkaloids (MIAs) show tightly regulated biosynthesis and accumulation in specific organelles of distinct cell types. However, the cell‐specific expression patterns of anticancer MIA camptothecin biosynthetic genes in Ophiorrhiza pumila and the regulatory mechanisms of camptothecin ...

Enhancing Antibacterial Efficacy: Combining Novel Bacterial Topoisomerase Inhibitors with Efflux Pump Inhibitors and Other Agents Against Gram-Negative Bacteria

Antibiotics
Background: The novel bacterial topoisomerase inhibitors (NBTIs) developed in our laboratory show potent on-target enzyme inhibition but suffer from low activity against Gram-negative bacteria.

RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation

Photochemistry and Photobiology, EarlyView.
UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...

Antibiotic‐mediated immune modulation in periodontitis

Periodontology 2000, EarlyView.
Abstract Periodontitis is a chronic inflammatory disease affecting the supporting structures of the teeth. Although initiated by dysbiotic microbial communities, its progression is largely driven by the host's uncontrolled inflammatory response. While antibiotics have conventionally been employed in periodontitis therapy for their antimicrobial ...

Bisacridine derivatives as effective eukaryotic topoisomerase II inhibitors

European Journal of Medicinal Chemistry
Fungal infections, particularly those caused by Candida species, pose a growing clinical challenge due to the increasing resistance to conventional antifungal agents and, in general, the limited arsenal of such drugs. In this study, we synthesized and tested a series of novel derivatives of bisacridines as potential antifungal compounds targeting ...

The role of extracellular vesicles in cell–cell crosstalk in cardiotoxicity

The Journal of Physiology, EarlyView.
Abstract figure legend Administration of a pharmacological agent can result in off‐target cardiotoxicity which can be driven by cell–cell crosstalk between healthy and dysfunctional cardiac cells. Extracellular vesicles (EVs) are lipid bilayer structures that can move biological cargo between cells, facilitating cell–cell crosstalk.
