 Workshop on Random Walks in Biological Physics with Focus on DNA and chromosome structure

Workshop on Random Walks in Biological Physics with Focus on DNA and chromosome structure

「物理生物與生物物理」研討會訊息DNA 複製、轉錄與修復是細胞中至關重要的基本過程。這些過程一旦失調,可能導致如癌症等疾病的發生。DNA 的機械性質,例如其持續長度(persistence length)與拓撲結構,也會影響這些生物過程。此外,許多與 DNA 互動的蛋白質也會改變 DNA 的機械性質。來自美國 Northwestern University 的理論生物物理學家 John Marko,其研究主要聚焦於 DNA 與染色體的物理與機械性質。他建立了多種理論架構,用以描述單分子層級下 DNA 的彈性、扭轉力學、超螺旋(supercoiling)以及拉伸行為。他的研究也延伸到細胞環境中的 DNA 與染色體,例如建立模型來描述在有絲分裂過程中,DNA 如何透過 loop extrusion 機制壓縮形成染色體,以及分子擁擠效應(molecular crowding)如何影響轉錄因子的結合。在「生物物理中的隨機漫步(Random Walks in Biological Physics)」工作坊中,他將發表一場物理所 Colloquium 演講,並開設 4 堂關於 DNA、染色體與細胞核的講座。此外,韓國浦項工科大學(POSTECH) 的 Jae-Hyung Jeon 教授也將在本次工作坊中開設 2 堂關於生命系統中異常擴散(anomalous diffusion)之隨機模型(stochastic modeling)**的課程。更多資訊與報名方式,請參閱網站:

The mechanical properties of DNA such as its persistence length and topology affect these processes, too. There are many proteins interacting with DNA affecting DNA’s mechanical properties, too. John Marko from Northwestern University is a theoretical biophysicist whose research focus on the physical and mechanical properties of DNA and chromosomes.He develops theoretical frameworks to describe DNA elasticity, torsional mechanics, supercoiling, and stretching at the single molecular level. He has also made contributions to understand DNA and chromosomes in the cellular context including models to describe DNA loop extrusion to compact chromosome during mitosis and how molecular crowding affects the binding of the transcriptional factors. To learn his work, please check out the workshop of random walks in biological physics. In a 3-day workshop, he will give a colloquium and 4 lectures on DNA, chromosomes, and nuclei. In addition, Jae-Hyung Jeon from Pohang University of Science and Technology (POSTECH) in South Korea also join force in this workshop to give 2 lectures on stochastic modeling on anomalous diffusion process in Living Systems.

【Recent trends in computer simulation in Physics, Chemistry and Biology 】

Applications of atomistic and molecular simulations has a long history in advancing our understanding of fundamental phenomena in Physics, Chemistry and Biology. Recent rapid developments in both hardware (CPU, GPU, TPU) and software (machine-learning potential, multi-scale simulation) enable new powerful tools to provide unprecedented precisions and details. In this workshop, we aim to bring experts in these fields to discuss not only the recent developments but also how to leverage on these new tools to address important scientific questions that are possible only synergetic interaction across scientific disciplines. We also have room for junior researchers (post-doc, Ph.D students,..) from different fields to give short oral presentations along with their posters.

中央研究院物理所演講資訊

【講題】Physics of Multicellular Systems【時間】1/20(二) 14:00
【地點】中央研究院物理研究所1F演講廳
【演講者】Professor Masaki Sano(Department of Physics, School of Science, The University of Tokyo)
【摘要】As all living organisms are composed of cells, cellular research is indispensable to understanding life. Consequently, efforts to understand the behavior of cells and populations of cells from a physics perspective are advancing. When addressing mechanical aspects such as cell motility and forces, it has become clear that the behavior of cell populations shows greater agreement between theory and experiment than that of single cells. This involves physical principles such as symmetry and the dominance of slow variables. This lecture addresses two problems concerning cells. One is the behavior of monolayers formed by motile cells, and the other is the problem of growing cell aggregates (organoids). Animals form their morphology during development by creating cavities (lumens) within cell aggregates and folding the resulting monolayers inward. Therefore, understanding the dynamics of monolayers and cavity formation within cell aggregates forms the foundation of cell collective research. This lecture introduces two studies:① Research investigating the role of directional order and topological defects in cell sheets, deriving a continuum model from individual cell movements and interactions, and comparing it with experiments.② Research examining the mechanism by which a central lumen forms in organoids growing from a few cells, while the monolayer remains stable during growth, through a comparison of a model and experiments【接待人】Dr. Tetsuya Hiraiwa 平岩徹也副研究員 (中央研究院物理研究所)
