Multicolour interphase cytogenetics: 24 chromosome probes, 6 colours, 4 layers [PDF]

open access: yes, 2011
From the late 1980s onwards, the use of DNA probes to visualise sequences on individual chromosomes (fluorescent in-situ hybridisation - FISH) revolutionised the study of cytogenetics.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Simultaneous Real-Time Detection of Initiator- and Effector-Caspase Activation by Double Fluorescence Resonance Energy Transfer Analysis

open access: yesJournal of Pharmacological Sciences, 2005
Fluorescence resonance energy transfer (FRET) with green fluorescent protein (GFP) variants has become widely used for biochemical research. In order to expand the choice of fluorescent range in FRET analysis, we designed various color versions of the ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Homologous cholinergic fluorescent probes. Synthesis and fluorescence properties [PDF]

open access: yesFEBS Letters, 1978
The advantages of using specifically designed fluorescent molecules to probe ligand binding sites on proteins, have been recognised [1]. Cholinesterases [2-4], acetylcholine receptor rich fragments from Torpedo marmorata[5,6] and an acetylcholine binding lipoprotein [7] have been studied using fluorescent trialkylammonium ligands.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Recent Progress in the Rational Design of Biothiol-Responsive Fluorescent Probes

open access: yesMolecules, 2023
Biothiols such as cysteine, homocysteine, and glutathione play significant roles in important biological activities, and their abnormal concentrations have been found to be closely associated with certain diseases, making their detection a critical task.

Fluorescent Probes for Biological Imaging [PDF]

open access: yesBioMed Research International, 2016
Owing to the high sensitivity, high resolution, and the wealth of contrast mechanisms, fluorescence imaging is the most versatile and widely used visualization modality to study the structure and function of biological systems and the molecular process in living organisms without perturbing them.
