Our lab has moved to the new research laboratory building at CCME! The new space is divided into four areas: the Biochem Lab and Chem Biol Lab are on the fifth floor, next to our offices, while the tissue culture room and imaging room are located in the basement. Despite the substantial effort required to move equipment and reagents, we managed to settle in within a week. Everyone has been doing a fantastic job!
In the past, we have used voltage imaging to visualize the initiation of action potentials at the axon initial segment (AIS). Recently, we have shifted our focus to investigating the molecular inventory of this intriguing subcellular compartment. In a publication in Nature Communications, we introduced an immunoproximity labeling approach that targets the endogenous AIS protein neurofascin for precise and high-resolution mapping of AIS proteins. Immuno-PL has enabled us to uncover AIS protein components and their dynamic changes throughout neuronal development. The instructional proteome has empowered us to discern authentic AIS-enriched proteins, including SCRIB, a discovery validated through collaboration with Professor Matthew Rasband’s research group at Baylor College of Medicine. This powerful and adaptable approach not only refines our understanding of the AIS proteome but also serves as a valuable resource to unravel the intricate mechanisms that regulate the structure and function of the AIS.
To enhance the voltage sensitivity of eFRET GEVIs, we explored a novel approach involving the insertion of red fluorescent proteins into the extracellular loop of rhodopsin proteins. This unconventional method yielded a surprisingly high dynamic range compared to the conventional practice of appending fluorescent proteins to the termini. In the recent issue of Science Advances, we present the engineering of these red eFRET GEVIs, named Cepheid1b and Cepheid1s, which exhibit improved voltage response, brightness, and photo-stability. These advancements facilitate voltage imaging in mouse brain slices with minimal laser power, uncovering burst firing and subthreshold depolarization activities in multiple neurons. Notably, Cepheid indicators support multiplexed imaging alongside green fluorescent indicators for calcium or glutamate, offering comprehensive insights into cellular dynamics. Furthermore, their compatibility with CheRiff, a spectrally orthogonal optogenetic actuator, enables all-optical electrophysiology measurements of neuronal excitability. In a notable application, Cepheid1b enables non-invasive observation of glucose-stimulated correlations between electrical spiking and calcium oscillations in pancreatic islet tissue. These findings mark a significant advancement in voltage imaging technology, promising deeper insights into cellular function and opening avenues for innovative neuroscientific and biomedical research endeavors.
When cells encounter stressors such as oxidation, osmotic shock, or starvation, they activate a series of response pathways, including the formation of stress granules (SGs). These SGs are membraneless organelles vital for cellular functions and are often implicated in neurodegenerative diseases. Understanding the molecular composition of SGs is essential for comprehending their biological role in stress response. In a recent publication in Nature Communications, we utilized the photocatalytic RNA labeling and sequencing method, CAP-seq, to systematically profile the transcriptome of SGs in live cells with unprecedented spatial resolution. CAP-seq analysis revealed stress-specific mRNA targeting to SGs under conditions such as oxidative stress or osmotic shock. Furthermore, CAP-seq unveiled the temporal dynamics of RNA localization during SG disassembly, revealing a model of AU-rich, translationally repressed SG nanostructures persisting after stress cessation. These findings shed new light on the molecular mechanisms underlying SG function in cellular stress responses and neurodegenerative disorders.
Eukaryotic cells, with their highly compartmentalized nature, rely on precisely regulated protein trafficking for their proper functioning. As a prime example, the secretory pathway orchestrates the journey of membrane receptors from synthesis in the endoplasmic reticulum (ER) to their eventual destination at the plasma membrane, involving crucial stops at the Golgi apparatus and vesicles. While existing chemical tools have enabled the measurement of protein turnover at the whole-cell level, they often lack the much-needed subcellular spatial resolution. In the recent issue of Nature Communications, we describe the development of prox-SILAC technique, a fusion of proximity labeling and pulse-SILAC metabolic tagging, which promises to fill this gap. Prox-SILAC reveals the intricate dynamics of protein turnover within cellular organelles, including the mitochondria and the ER, shedding new light on cellular activities under both physiological and pathological conditions.
Spatiotemporally resolved mapping of neuronal action potentials (APs) not only requires highly sensitive voltage indicators, but also depends on high-speed imaging apparatus. Ideally, the acquisition rate of voltage imaging should exceed 1 kilohertz to capture the millisecond timescale APs. However, even with the fastest cameras that money can buy, such as scientific CMOS cameras, the full frame acquisition rate is often limited to 100 Hz. While higher speed could be achieved by reducing the number of pixels, this comes with the price of smaller field of view. To address this challenge, we came up with a strategy to boost the effective camera acquisition rate via stroboscopic illumination scheme. Our idea was inspired by high-speed stroboscopic photography, where the object is briefly illuminated with a flash of light, whose duration is much shorter than the camera shutter. The temporal precision is thus defined by the pulse duration of flashed light rather than the camera shutter. This technique is most famously shown by the photo Bullet through Apple, made by Harold E. Edgerton back in 1964. Published in the recent issue of Chem. Biomed. Imaging, our stroboscopic voltage imaging technique achieved 5-fold improvement in the temporal resolution, allowing the mapping of both intercellular and intracellular electrical signaling. This paper has been selected as ACS Editor's Choice.
Voltage imaging often operates in shot noise-limited regime with a tight photon budget. Hybrid voltage indicator (HVI) design aims to solve this problem by employing bright and photostable synthetic fluorophores. In the recent issue of PNAS, we report upgraded versions of HVIs that enable continuous voltage imaging for 30 min. This work is in collaboration with Prof. Zhixing Chen's group, who developed cyclooctatetraene-conjugated dyes with substantially improved photostability and reduced phototoxicity.
Seeing is believing. Our understanding of cellular physiology has been greatly advanced with the development of optical imaging instruments. It is now possible to detect small variations in functional phenotypes within a heterogeneous cell population, which could arise from alterations at the genetic, epigenetic or transcriptomic levels. However, it remains challenging to efficiently link the observed phenotype to the underlying genotype. To address this challenge, we have built a microscope to allow imaging-guided cell selection. Published in Cell Reports Methods, we describe the development and applications of such method in the context of engineering genetically encoded indicators.
We have a record-high number of graduates this year! Congratulations to Shuzhang, Gang, Junqi, Luxin, Ruixuan, and Yi for defending their PhD thesis. Thank you all for your hard work and contributions to the lab over the past years. Congratulations to Han, Peiyuan, Ruijie, and Wenyu for defending their undergraduate thesis!

Peng is humbled and honored to receive the Life Chemistry Award from Chinese Chemical Society. The award is presented by the Chemical Biology Committee during the 33rd Chinese Chemical Society Congress in Qingdao. We are both deeply grateful and immensely encouraged by the recognition of our work on chemical neuroscience.
Despite broad distributions throughout the cytoplasm, RNA molecules are conventionally believed to be excluded from the secretory pathway compartments including the endoplasmic reticulum (ER). Recent discovery of RNA N-glycan modification (glycoRNAs) has challenged this view, but direct evidence of RNA localization in the ER lumen has been lacking. To resolve this issue, we applied our recently upgraded version of MERR APEX-seq with enhanced sensitivity to the ER. Published in Biochemistry, we were surprised to identify small non-coding RNAs in the ER lumen of human embryonic kidney 293T cells and rat cortical neurons. These include U RNAs and Y RNAs, which raises interesting questions regarding their transport mechanism and biological functions in the secretory pathway.
There has been a missing piece in our previous work on photocatalytic RNA labeling and DNA labeling with CAP-seq: in addition to nucleic acids, proteins too could get oxidized with photo-controlled release of singlet oxygen. Mapping the subcellular proteome with genetically encoded photocatalyst is appealing, as the light trigger offers precise temporal control of labeling. With patterned illumination schemes, it is even possible to spatially modulate labeling. Published in Nature Communications, we report the development of photocatalytic protein labeling with a genetically encoded protein tag, miniSOG. Our method, called RinID, can be broadly applied in multiple organelles, including the mitochondrial matrix, nucleus and the endoplasmic reticulum (ER). The temporal control of RinID enables pulse-chase labeling of ER proteome in HeLa cells, which reveals substantially higher clearance rate for secreted proteins than ER resident proteins. Now the toolbox is complete! Also check out our recent review of the state-of-the-art in the field of photocatalytic proximity labeling for profiling the subcellular organization of biomolecules, published in Chembiochem.

Voltage imaging offers an unique opportunity to measure the dynamics of action potential initiation and propagation, with a sub-micrometer spatial resolution that is unattainable by conventional patch-clamp electrophysiology. In two recently published research articles, we collaborated with Profs. Yan Zhang and Louis Tao at PKU to image action potential dynamics in cultured primary neurons with rhodopsin-based GEVIs. We mapped the velocity of action potentials at the axon initial segment (Zoological Research) and followed its back-propagation into somatodendrites (Neuroscience Bulletin). The observed action potential dynamics are explained through computational simulation.

The dynamic RNA-protein interactions play crucial roles in cellular physiology, yet characterizing these interactions in their native cellular context at the proteomic level has remained challenging. Published in Angewandte Chemie International Edition, we report a photocatalytic crosslinking (PhotoCAX) strategy for studying the composition and dynamics of protein–RNA interactions via mass spectrometry (PhotoCAX-MS) as well as RNA sequencing (PhotoCAX-seq). By integrating the blue light-triggered photocatalyst with a dual-functional RNA–protein crosslinker (RP-linker) and the phase separation-based enrichment strategy, PhotoCAX-MS reveals the dynamic change of RBPome in macrophage cells upon LPS-stimulation, as well as RBPs interacting directly with the 5′ untranslated regions of SARS-CoV-2 RNA. This work is the result of a collaboration with Prof. Peng Chen's group at PKU.
We have reported a sensitive method for profiling newly transcribed RNA with subcellular resolution in live cells. Published in Cell Chemical Biology, our method combines APEX-seq with non-canonical ribonucleoside metabolic incorporation, which enhances the biotinylation efficiency of APEX labeling. Application of this technique to the nuclear lamina reveals local transcripts involved in histone modification, chromosomal structure maintenance, RNA splicing and processing.

What happens when proximity labeling meets protein post-translational modification profiling? In collaboration with Prof. Peng Chen's group at PKU, we have developed a method for mapping subcellular phosphoproteome in living cells and animals. Our method, called SubMAPP, capitalizes on the genetically encoded bioorthogonal decaging strategy, which enables the rapid activation of subcellular localized proximity labeling biotin ligase through either light illumination or small-molecule triggers. This is then followed by the orthogonal pull-down of phosphopeptides and quantitative protein mass spectrometry analysis. SubMAPP allows for the investigation of subcellular phosphoproteome dynamics, revealing the altered phosphorylation patterns of endoplasmic reticulum luminal proteins when cells are under stress.
Yu and Chen are enrolled in the CLS graduate program and have just finished their rotations. Both were undergraduates at CCME and trained in physical chemistry (Yu) and organic chemistry (Chen) labs.

Our hybrid voltage indicator (HVI) paper is officially online at Nature Chemistry! Since the inception of Flare indicator in 2018, we have been working hard to implement this strategy in live neurons. Thanks to Diels-Alder reaction, we are able to assemble a palette of bright and sensitive HVIs in cultured rat hippocampal neurons. The most red-shifted HVI-Cy5 faithfully reports neuronal spikes in the far-red emission range and could be paired with optogenetic actuators and green/red-emitting fluorescent indicators, allowing multiplexed imaging and all-optical electrophysiology. We look forward to using this expanded toolbox in the high-throughput screening of neuronal ion channel agonists/antagonists. Congratulations to Shuzhang, Chang, Yongxian, and our collaborators in Prof. Peng Chen's group at PKU. To read more about the history of this work, check out our "Behind the Paper" post at Nature Portfolio Chemistry Community.

Congratulations to Yuxin's enTRAP-seq paper, published in the special issue of Biochemistry! As you read this news, your DNA is continuously under attack by reactive metabolites (particularly endogenous oxidants). Meanwhile, your cells are busy clearing up the resulting DNA damages, which have ramifications in tumorigenesis and gene expression control. To help illuminate the cellular mechanisms and the functional roles of oxidative DNA damage, we developed a genome-wide 8-oxoguanine profiling technique, termed enzyme-mediated trapping and affinity precipitation of damaged DNA and sequencing, or enTRAP-seq for short. When applied to analyze guanine oxidation in mouse embryonic fibroblast cells, enTRAP-seq revealed the enrichment of 8-oxoguanine in transcriptionally active chromatin regions.
We exchanged gifts and memorable moments of 2019 at the New Year party. This year's Lab Stars are: Ruixuan, Luxin, Ran, Ying, Wei, Ruirui, Shuzhang, Gang, Yuxin, and Feng. Congratulations and thank you all for your hard work!

Our work on hybrid voltage indicator is accepted in Angewandte Chemie International Edition! By site-specifically modifying microbial rhodopsin on live cell surface with organic fluorophores, we created a palette of hybrid indicators with combined merits of small molecules (bright, photostable and small in size) and proteins (genetically targetable). The best of this series, called Flare1, has submillisecond response speed and superior sensitivity than the previous generation of fluorescent protein-based sensors. It allowed us to investigate the spatial and temporal correlation of electrical coupling among mammalian cells. Future developments are underway to achieve voltage imaging in neurons or in vivo. Read more about the design and deployment of hybrid indicators to neuroscience research in our recent review in ACS Chemical Neuroscience.

The past decade has seen a proliferation of fluorescent voltage indicators. Given the multiple choices, each with different tradeoffs between response speed and sensitivity, brightness and spectral range, one might ask: which sensor is better? In a recent review published by our group and Prof. Adam Cohen at Harvard University, we outlined the history of these voltage indicators, highlighting those with promising characteristics for in vivo imaging. We also discussed protein engineering strategies that gave rise to these sensors, and hoped that this article will inspire novel ideas for better probes. Read about it in Current Opinion in Chemical Biology.
We are delighted to have Ruirui Ma and Yuxin Fang joining our group. Ruirui is a first year CCME graduate student with prior research interest in inorganic and physical chemistry.
