报告题目:Reconstruction of complex genomes with long error prone reads

摘要Genome is the carrier that carries all the mysteries of life. Therefore, obtaining the genome is the key to deciphering the mysteries of life. The rapid development of sequencing technology and computing technology has made it possible to accurately calculate and predict the genome of all species. Taking this opportunity, the speaker, Professor Guojun Li, will introduce the historical process of sequencing data, the application of graph theory and combinatorial optimization to biological data analysis, and share their latest progress in genome reconstruction using long error prone sequencing data.

报告题目:Explainable Artificial Intelligence for Discovery of Anti-Cancer Drug Targets

摘要The discovery of anti-cancer drug targets is of fundamental importance for cancer medicine. Synthetic lethality (SL) is a type of genetic interaction typically between two genes, which is that perturbations to both genes will kill a cell but perturbation to one gene will not. It is a gold mine of anti-cancer drug targets since targeting an SL partner of a gene with cancer-specific abnormality can selectively kill cancer cells without harming normal cells. Current wet-lab screening methods usually have high cost, while statistical and machine learning methods cannot fully utilize the prior knowledge or lack clear explanations. We have developed a series of deep learning methods using Knowledge Graphs (KGs) and Explainable Artificial Intelligence (XAI) to predict SLs and understand mechanisms behind. SynLethDB is a comprehensive database including many SL gene pairs and a knowledge graph named SynLethKG. KG4SL is the first method using KG for SL prediction (ISMB/ECCB 2021). PiLSL further focuses on pairwise interaction learning from KGs for predicting SLs with interpretability (ECCB 2022). Recently, we proposed KR4SL, which employs path-based knowledge reasoning to rank SL candidate partners for given primary genes, and is able to explain the SL prediction and biological mechanisms clearly (ISMB/ECCB 2023). Our ongoing work combines pre-trained Language Models (e.g. GPT) and KGs to explain SLs in natural languages. In future, we aim to unlock the power of XAI by integrating more data and knowledge, and promoting closer collaborations with wet-lab biologists, clinical scientists and pharmaceutical researchers, to catalyze advancements of AI for cancer precision medicine.

报告题目:The whole-brain single-cell spatial transcriptome atlas and cross-species comparison

摘要The brain is the most complex organ of humans with the highest heterogeneity of cell types. The composition and spatial location of different neuron subtypes, as well as their precise connections, are the basis for brain functions. Rapid advances in spatial transcriptomic technologies allow spatial mapping of gene expression as well as cellular subtypes at single-cell resolution of brain sections. We applied Stereo-Seq technology developed by BGI, to construct the whole-brain cell atlas for macaques, marmoset, and mice, with hundreds of coronal slices of spatial transcriptome across the whole brain per animal. Single-cell spatial transcriptome reveals cell-type organization in the macaque cortex and cross-species comparative analysis identified primate-specific cell types enriched in cortical layer 4, whose marker genes are expressed in a region-dependent manner (Chen et al., Cell 2023). Whole-brain cell atlas provides the cellular and molecular basis for understanding the function, evolution, development, aging, and pathogenesis of the brain.

报告题目: The application of multi-omics data integration in brain atlas studies

摘要The neocortex is greatly expanded in primates compared with rodents, especially the prefrontal cortex. Understanding its brain organization at the cellular level holds the key to deciphering neural circuit functions of the primate brain and to developing treatments for brain disorders. To systematically elucidate the cellular diversity in primates at single-cell and spatial resolution, here we performed large-scale single-nucleus RNA-seq and spatial transcriptome analysis for millions of cells covering 143 cortical regions of cynomolgus monkeys. We derived a comprehensive cell-type taxonomy of neuronal and non-neuronal cells in the macaque cortex. Spatial mapping revealed laminar and regional preferences of various cell types and regional differences in cell-type composition and neighborhood complexity. Further comparative analysis revealed glutamatergic neuron types in the cortex of primates with layer-specific distribution and high expression of functionally important genes. Together, these results demonstrate the increased complexity of glutamatergic neuron subtypes in primates, and provide spatial underpinning for molecular understanding of organizing principles of the primate brain.
