- 요약Cells are spatially organized multi-scaled systems where precise protein localization underpins cellular identity, function, and dynamic response to perturbations. Spatial proteomics provides a powerful framework to systematically characterize this organization and elucidate underlying biological mechanisms at subcellular resolution.This thesis is a body of di↵erent works that investigate cell biology from a spatial proteomic angle and provide some tools to approach modeling subcellular proteins for systematic understanding.Chapter 2 described the first e↵ort to predict single cell protein localization from confocal microscopy images. We designed and analyzed a citizen science competition to predict single cell classification labels for both single- and multilocalization. The main challenges for this representation learning competition include class imbalance, weak labels, and multi-label classification across 19 classes in 17 di↵erent human cell lines. Diverse strategies were employed, and the winning models serve as one of the first subcellular omics tools capable of capturing subcellular features, cellular dynamics and accurate single-cell labels.Chapter 3 described a signal processing and machine learning framework to create a common shapespace and map proteins representation in a common coordinate of the cell based on cell and nuclei shapes. We performed an integrated analysis linking organelle, pathway, and single-protein levels to shapespace. While subcellular organelle topology remained robust across shape spacebut varied between cell lines, single-protein analysis showed that shape differences within the same cell cycle phase may indicate distinct cell fates, with many non-cell cycle proteins exhibiting shape-dependent variation, enabling the study of protein spatial shifts under perturbation within a common coordinate framework.Chapter 4 investigated landscape of protein reorganization in host-virus under SARS-CoV-2 infection. We performed a large-scale immunofluorescence screening of 602 host proteins and identified ˜100 proteins with altered abundance or localization upon infection. Many of this proteins were validated in another cell lines, with some di↵erences highlighting the heterogeneity in response to virus infection. Using the identified di↵erential protein list, we screened 12 approved small-molecules drug targeting these proteins and identified elesclomol and rimcazole as potential antiviral candidate. Our study can serve as a systematic approach for drug repurposing, and the generated dataset of more than 100,000 immunofluorescence images was published as a resource available for further studies.Chapter 5 focused on tool development, aiming to open-source some key bioimage analysis and modeling tasks.Chapter 5.1. presented an interactive training and annotation framework, accessible via a web app for real-time monitoring and annotation, while a connected backend server handles model training. This addressed the growing role of deep learning in bioimage analysis, where the lack of user-friendly tools hindered broader adoption. Many existing platforms struggled with model re-training and fine-tuning, which are essential for preventing overfitting, particularly with limited training data. Our approach leveraged interactive model training, allowing real-time refinement, as demonstrated with segmentation models, achieving a 6x faster workflow compared to conventional methods.Chapter 5.2 described generative models for organelle staining, one steptoward the whole proteome virtual cell painting. Label-free organelle prediction, or virual cell painting, is a longstanding challenge in cellular imaging, o↵ering a way to overcome the limitations of fluorescence microscopy, such as high costs, cytotoxicity, and labor-intensive protocols. This paper propose a simplified VQGAN adaptable to various input/output channel numbers for image-to-image translation, enabling multi-channel organelle staining prediction from transmitted light images. The approach won first place in ISBI 2024 Light My Cell competition on Grand Challenge platform.
