Propargylated Purine Deoxynucleosides: New Tools for Fluorescence Imaging Strategies.

ABSTRACT: In vivo imaging of biological processes is an important asset of modern cell biology. Selectively reacting fluorophores herein are an important tool and click chemistry reactions take a large share in these events. 5-Ethynyl-2'-deoxyuridine (EdU) is well known for visualizing DNA replication, but does not show any selectivity for incorporation into DNA. Striving for specific visualization of virus replication, in particular HIV replication, a series of propargylated purine deoxynucleosides were prepared aiming for selective incorporation by HIV reverse transcriptase (RT). We here report on the synthesis and preliminary biological effects (cellular toxicity, HIV inhibitory effects, and feasibility of the click reaction) of these nucleoside analogues.

An ameliorative protocol for the quantification of purine 5',8-cyclo-2'-deoxynucleosides in oxidized DNA.

Project description:5',8-Cyclo-2'-deoxyadenosine (cdA) and 5',8-cyclo-2'-deoxyguanosine (cdG) are lesions resulting from hydroxyl radical (HO (·) ) attack on the 5'H of the nucleoside sugar moiety and exist in both 5'R and 5'S diastereomeric forms. Increased levels of cdA and cdG are linked to Nucleotide Excision Repair (NER) mechanism deficiency and mutagenesis. Discrepancies in the damage measurements reported over recent years indicated the weakness of the actual protocols, in particular for ensuring the quantitative release of these lesions from the DNA sample and the appropriate method for their analysis. Herein we report the detailed revision leading to a cost-effective and efficient protocol for the DNA damage measurement, consisting of the nuclease benzonase and nuclease P1 enzymatic combination for DNA digestion followed by liquid chromatography isotope dilution tandem mass spectrometry analysis.

Influence of Lens Fluorescence on Fluorescence Lifetime Imaging Ophthalmoscopy (FLIO) Fundus Imaging and Strategies for Its Compensation.

Project description:PurposeTo explore the contribution of crystalline lens fluorescence to fluorescence lifetimes measured with fluorescence lifetime imaging ophthalmoscopy (FLIO) and to propose a computational model to reduce the lens influence.MethodsFLIO, which detects autofluorescence decay over time in a short-wavelength spectral channel (SSC, 498-560 nm) and a long-wavelength spectral channel (LSC, 560-720 nm), was performed on 32 patients before and after cataract extraction. The mean autofluorescence lifetime (τ m ) of the fundus was determined from a three-exponential fit of the postoperative fluorescence decays. The preoperative measurements were fit with series of exponential functions in which one fluorescence component was time-shifted in order to represent lens fluorescence.ResultsPostoperatively, τ m was 185 ± 22 ps in the SSC and 209 ± 34 ps in the LSC at the posterior pole. These values were best reproduced by fitting the postoperative measurements with a three-exponential model with a time-shifted third fluorescence component (SSC, 203 ± 45 ps; LSC, 215 ± 29 ps), whereas disregarding time-shifted lens fluorescence resulted in significantly (P < 0.001) longer τ m values (SSC, 474 ± 206 ps; LSC, 215 ± 29 ps). The fluorescence of the cataract lens contributed to the total fluorescence by 54.2 ± 10.6% (SSC) and 29.5 ± 9.9% (LSC).ConclusionsCataract lens fluorescence greatly alters fluorescence lifetimes measured at the fundus by FLIO, resulting in an overestimation of the lifetimes; however, this may be compensated for considerably by taking lens influence into account in the fitting model.Translational relevanceThis study investigates cataract fluorescence in FLIO and a mathematical model for compensation of this influence.

Advances in fluorescence labeling strategies for dynamic cellular imaging.

Project description:Synergistic advances in optical physics, probe design, molecular biology, labeling techniques and computational analysis have propelled fluorescence imaging into new realms of spatiotemporal resolution and sensitivity. This review aims to discuss advances in fluorescent probes and live-cell labeling strategies, two areas that remain pivotal for future advances in imaging technology. Fluorescent protein- and bio-orthogonal-based methods for protein and RNA imaging are discussed as well as emerging bioengineering techniques that enable their expression at specific genomic loci (for example, CRISPR and TALENs). Important attributes that contribute to the success of each technique are emphasized, providing a guideline for future advances in dynamic live-cell imaging.

Purine deoxynucleosides and adenosine dialdehyde decrease 5-amino-4-imidazolecarboxamide (Z-base)-dependent purine nucleotide synthesis in cultured T and B lymphoblasts.

Project description:Deoxyadenosine (dAdo) and deoxyguanosine (dGuo) decrease methionine synthesis from homocysteine in cultured lymphoblasts; because of the possible trapping of 5-methyltetrahydrofolate this could lead to decreased purine nucleotide synthesis. Since purine deoxynucleosides could also inhibit purine synthesis de novo at an early step not involving folate metabolism, we measured in azaserine-treated cells 5-amino-4-imidazolecarboxamide (Z-base)-dependent purine nucleotide synthesis using [14C]formate. In the T lymphoblasts, Z-base-dependent purine nucleotide synthesis was decreased 26% by 0.3 microM-dAdo, 21% by 1 microM-dGuo and 28% by 1 microM-adenosine dialdehyde, a potent S-adenosylhomocysteine hydrolase inhibitor; homocysteine fully reversed the inhibitions. The B lymphoblasts were considerably less sensitive to the deoxynucleoside-induced decrease in Z-base-dependent purine nucleotide synthesis, with 100 microM-dAdo required for significant inhibition and no inhibition by dGuo at this concentration; homocysteine partly reversed the inhibition by dAdo. The observed decrease in Z-base-dependent purine nucleotide synthesis could not be attributed either to dUMP depletion changing the folate pools or to decreased ATP availability because dUrd was without effect and during the experimental period the intracellular ATP concentration did not change significantly. Cells with 5,10-methylenetetrahydrofolate reductase deficiency were relatively resistant to inhibition of Z-base-dependent purine nucleotide synthesis by dAdo and adenosine dialdehyde. Our results suggest that deoxynucleosides decrease purine nucleotide synthesis by trapping 5-methyltetrahydrofolate.

Precise immuno-fluorescence canceling enables highly multiplexed imaging [RNA-seq]

Project description:Cell states are regulated by extrinsic signals from various external factors such as intercellular interactions, and intrinsic gene expression. Although comprehensive cell state profiling has been attempted, it remains simultaneous analysis of signal activation has still been challenging. Multiplexed imaging is a technique acquiring multiple protein information at a single cell level as traditional immunofluorescence. However, the method often compromises resolution, hindering the analysis of intracellular localization dynamics and post-translational modifications of proteins. To address these limitations, we developed an erasable fluorescence method using disulfide linkers to label antibodies. We term these antibodies ‘Precise Emission Canceling Antibodies (PECAbs)’. PECAb allows for high-resolution iterative imaging with minimal non-specific binding. Automation enables our system to achieve reproducible quantitative analysis using 206 antibodies. The resulting quantitative data allow reconstruction of the spatiotemporal dynamics of signaling pathways over both long and short timescales. Additionally, combining this approach with sequential RNA-FISH can effectively classify cells and identify their signal activation states in human tissue. Overall, the PECAb system serves as a comprehensive platform for analyzing complex cell processes, from signal transduction to gene expression.

New generation ICG-based contrast agents for ultrasound-switchable fluorescence imaging.

Project description:Recently, we developed a new technology, ultrasound-switchable fluorescence (USF), for high-resolution imaging in centimeter-deep tissues via fluorescence contrast. The success of USF imaging highly relies on excellent contrast agents. ICG-encapsulated poly(N-isopropylacrylamide) nanoparticles (ICG-NPs) are one of the families of the most successful near-infrared (NIR) USF contrast agents. However, the first-generation ICG-NPs have a short shelf life (<1 month). This work significantly increases the shelf life of the new-generation ICG-NPs (>6 months). In addition, we have conjugated hydroxyl or carboxyl function groups on the ICG-NPs for future molecular targeting. Finally, we have demonstrated the effect of temperature-switching threshold (Tth) and the background temperature (TBG) on the quality of USF images. We estimated that the Tth of the ICG-NPs should be controlled at ~38-40?°C (slightly above the body temperature of 37?°C) for future in vivo USF imaging. Addressing these challenges further reduces the application barriers of USF imaging.

X-ray fluorescence imaging: a new tool for studying manganese neurotoxicity.

Project description:The neurotoxic effect of manganese (Mn) establishes itself in a condition known as manganism or Mn induced parkinsonism. While this condition was first diagnosed about 170 years ago, the mechanism of the neurotoxic action of Mn remains unknown. Moreover, the possibility that Mn exposure combined with other genetic and environmental factors can contribute to the development of Parkinson's disease has been discussed in the literature and several epidemiological studies have demonstrated a correlation between Mn exposure and an elevated risk of Parkinson's disease. Here, we introduce X-ray fluorescence imaging as a new quantitative tool for analysis of the Mn distribution in the brain with high spatial resolution. The animal model employed mimics deficits observed in affected human subjects. The obtained maps of Mn distribution in the brain demonstrate the highest Mn content in the globus pallidus, the thalamus, and the substantia nigra pars compacta. To test the hypothesis that Mn transport into/distribution within brain cells mimics that of other biologically relevant metal ions, such as iron, copper, or zinc, their distributions were compared. It was demonstrated that the Mn distribution does not follow the distributions of any of these metals in the brain. The majority of Mn in the brain was shown to occur in the mobile state, confirming the relevance of the chelation therapy currently used to treat Mn intoxication. In cells with accumulated Mn, it can cause neurotoxic action by affecting the mitochondrial respiratory chain. This can result in increased susceptibility of the neurons of the globus pallidus, thalamus, and substantia nigra pars compacta to various environmental or genetic insults. The obtained data is the first demonstration of Mn accumulation in the substantia nigra pars compacta, and thus, can represent a link between Mn exposure and its potential effects for development of Parkinson's disease.
