Super-resolution imaging lysosome vesicles and establishing a gallbladder-visualizable zebrafish model via a fluorescence probe. Talanta 2024; 279:126656. [PMID: 39098243 DOI: 10.1016/j.talanta.2024.126656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 07/24/2024] [Accepted: 07/31/2024] [Indexed: 08/06/2024]
Abstract
Advanced probes for imaging viscous lipids microenvironment in vitro and in vivo are desirable for the study of membranous organelles and lipids traffic. Herein, a reaction-based dihydroquinoline probe (DCQ) was prepared via linking a diethylamino coumarin fluorophore with a N-methylquinoline moiety. DCQ is stable in low viscous aqueous mediums and exhibits green fluorescence, which undergoes fast autoxidation in high viscous mediums to form a fluorescent product with deep-red to near-infrared (NIR) emission, rendering the ability for dual-color imaging. Living cell imaging indicated that DCQ can effectively stain lysosomal membranes with deep-red fluorescence. Super-resolution imaging of lysosome vesicles has been achieved by DCQ and stimulated emission depletion (STED) microscopy. In addition, DCQ realizes multiple organs imaging in zebrafish, whose dual-color emission can perfectly discriminate zebrafish's yolk sac, digestive tract and gallbladder. Most importantly, DCQ has been successfully used to establish a gallbladder-visualizable zebrafish model for the evaluation of drug stress.

Abstract
Ferroptosis is an iron-dependent programmed cell death that is characterized by the dysregulation of lipid reactive oxygen species (ROS) production, causing abnormal changes in hypochlorous acid (HClO) levels in lysosomes. Super-resolution imaging can observe the fine structure of the lysosome at the nanometer level; therefore, it can be used to detect lysosome HClO levels during ferroptosis at the suborganelle level. Herein, we utilize a ratiometric fluorescent probe, SRF-HClO, for super-resolution imaging of lysosome HClO. Structured-illumination microscopy (SIM) improves the accuracy of lysosome targeting and enables the probe SRF-HClO to be successfully applied to rapidly monitor the up-regulated lysosome HClO at the nanoscale during inflammation and ferroptosis. Importantly, the probe SRF-HClO can also detect HClO changes in inflammatory and ferroptosis mice and evaluate the inhibitory effect of ferroptosis on mice tumors.

Abstract
Lysosomes have long been known for their acidic lumens and efficient degradation of cellular byproducts. In recent years, it has become clear that their function is far more sophisticated, involving multiple cell signaling pathways and interactions with other organelles. Unfortunately, their acidic interior, fast dynamics, and small size make lysosomes difficult to image with fluorescence microscopy. Here we report a far-red small molecule, HMSiR680-Me, that fluoresces only under acidic conditions, causing selective labeling of acidic organelles in live cells. HMSiR680-Me can be used alongside other far-red dyes in multicolor imaging experiments and is superior to existing lysosome probes in terms of photostability and maintaining cell health and lysosome motility. We demonstrate that HMSiR680-Me is compatible with overnight time-lapse experiments as well as time-lapse super-resolution microscopy with a frame rate of 1.5 fps for at least 1000 frames. HMSiR680-Me can also be used alongside silicon rhodamine dyes in a multiplexed super-resolution microscopy experiment to visualize interactions between mitochondria and lysosomes with only a single excitation laser and simultaneous depletion. We envision this dye permitting a more detailed study of the role of lysosomes in dynamic cellular processes and disease.

Organelle-Targeted Fluorescent Probes for Sulfane Sulfur Species. Antioxidants (Basel) 2023; 12:antiox12030590.

Abstract
Sulfane sulfurs, which include hydropersulfides (RSSH), hydrogen polysulfides (H2Sn, n > 1), and polysulfides (RSnR, n > 2), play important roles in cellular redox biology and are closely linked to hydrogen sulfide (H2S) signaling. While most studies on sulfane sulfur detection have focused on sulfane sulfurs in the whole cell, increasing the recognition of the effects of reactive sulfur species on the functions of various subcellular organelles has emerged. This has driven a need for organelle-targeted detection methods. However, the detection of sulfane sulfurs, particularly of RSSH and H2Sn, in biological systems is still a challenge due to their low endogenous concentrations and instabilities. In this review, we summarize the development and design of organelle-targeted fluorescent sulfane sulfur probes, examine their organelle-targeting strategies and choices of fluorophores (e.g., ratiometric, near-infrared, etc.), and discuss their mechanisms and ability to detect endogenous and exogenous sulfane sulfur species. We also present the advantages and limitations of the probes and propose directions for future work on this topic.

Abstract
The interactions between organelles can maintain normal cell activity. Lysosomes, as waste disposal systems of cells, have many important interactions with the plasma membrane, especially in the repair of cracked plasma membrane. Unfortunately, a way to study the relationship between them synchronously is still lacking. Therefore, in this work, we constructed a dual-targeting probe (Mem-Lyso) to simultaneously visualize the plasma membrane and lysosomes for the first time. Taking advantage of dual-targeting, the probe Mem-Lyso could successfully track and analyze the dynamic changes of the plasma membrane and lysosomes in different bioprocesses. The experimental results demonstrated that, compared to the normal status, there was obvious fusion between the plasma membrane and lysosomes in the apoptosis process. Furthermore, because of the sensitivity to polarity, Mem-Lyso could label the plasma membrane and lysosomes with red and yellow colors in cells, respectively. Moreover, the skeleton and gastrointestinal wall of zebrafish were visualized by dual-color imaging, respectively. More importantly, the dual-targeting property endowed Mem-Lyso with the ability to spatially distinguish the cholesterol (CL) content in the plasma membrane, which provided a potential detection tool for biological research and diagnosis of related diseases.

Abstract
Understanding the interactions between nanomaterials and biological systems plays an essential role in enhancing the efficacy of nanomedicines and deepening the understanding of the biological domain. Fluorescence microscopy is a powerful optical imaging technique that allows direct visualization of the behavior of fluorescent-labeled nanomaterials in the intracellular microenvironment. However, conventional fluorescence microscopy, such as confocal microscopy, has limited optical resolution due to the diffraction of light and therefore cannot provide the precise details of nanomaterials with diameters of less than ∼250 nm. Fortunately, the development of super-resolution fluorescence microscopy has overcome the resolution limitation, enabling more comprehensive studies of nano-cell interactions. Herein, we have summarized the recent advances in nano-cell interactions investigated by a variety of super-resolution microscopic techniques, which may benefit researchers in this multi-disciplinary area by providing a guideline to select appropriate platforms for studying materiobiology.

Abstract
Super-resolution microscopy (SRM) imaging of the finite subcellular structures and subtle bioactivities inside organelles delivers abundant cellular information with high fidelity to unravel the intricate biological processes. An ideal fluorescent probe with precise control of fluorescence is critical in SRM technique like stimulated emission depletion (STED). Si-rhodamine was decorated with both targeting group and H+ -receptor, affording the dually fluorogenic Si-rhodamine in which the NIR fluorescence was efficiently controlled by the coalescent of spirolactone-zwitterion equilibrium and PeT mechanism. The dually fluorogenic characters of the probe offer a perfect mutual enhancement in sensitivity, specificity and spatial resolution. Strong fluorescence only released in the existence of targeting protein at acidic lysosomal pH, ensured precisely tracking the dynamic of lysosomal structure and pH in living cells by STED.

Abstract
Structured illumination microscopy (SIM) is widely used in biological imaging for its high resolution, fast imaging speed, and simple optical setup. However, when imaging thick samples, the structured illumination patterns in SIM will suffer from optical aberrations, leading to a serious deterioration in resolution. Therefore, it is necessary to reconstruct structured illumination patterns with high quality and efficiency in deep tissue imaging. Here we demonstrate an adaptive optics (AO) correction method based on deep learning in wide-field SIM imaging system. The mapping between the coefficients of the first 15 Zernike modes and their corresponding distorted patterns is established to train the convolution neural network (CNN). The results show that the optimized CNN can predict the aberration phase within ~10.1 ms with a personal computer. The correlation index between the aberration phases and their corresponding predicted aberration phase is up to 0.9986. This method is highly robust and effective for patterns with various spatial densities and illumination conditions and able to effectively correct the imaging distortion caused by optical aberration in SIM system.
