Model Systems in Centriole Biology

In course

BIO-221: Cell and developmental biology for engineers

Students will learn essentials of cell and developmental biology with an engineering mind set, with an emphasis on animal systems and quantitative approaches. ...

Description

This lecture by the instructor covers core questions and model systems in centriole biology, focusing on C. elegans, H. sapiens, C. reinhardtii, and T. agilis. It delves into asymmetric cell division, mathematical modeling, functional genomics, and proteomic analysis, providing insights into fundamental biological questions relevant for human health.

Andrew Charles Oates

After an undergraduate degree in Biochemistry at the University of Adelaide with Honours in Robert Saint’s lab, Andrew Oates received his Ph.D. at the Ludwig Institute for Cancer Research and the University of Melbourne in the lab of Andrew Wilks. His postdoctoral time was at Princeton University and the University of Chicago in the lab of Robert Ho, where his studies on the segmentation clock in zebrafish began in 1998. In 2003 he moved to Germany and started his group at the Max Planck Institute for Molecular Cell Biology and Genetics in Dresden. In 2012 he accepted a position at University College London as Professor of vertebrate developmental genetics and moved his group to the MRC-National Institute for Medical Research at Mill Hill in London. From April 2015, he became a member of the Francis Crick Institute in London. In September 2016, he joined École polytechnique fédéral de Lausanne (EPFL) in Switzerland as a Professor, where he is the head of the Timing, Oscillation, Patterns Laboratory. From April 2018 he served as Director of the Institute of Bioengineering, and from January 2021 became the Dean of the School of Life Sciences. The Timing, Oscillation, Patterns Laboratory is composed of biologists, engineers, and physicists using molecular genetics, quantitative imaging, and theoretical analysis to study a population of coupled genetic oscillators in the vertebrate embryo termed the segmentation clock. This system drives the rhythmic, sequential, and precise formation of embryonic body segments, exhibiting rich spatial and temporal phenomena spanning from molecular to tissue scales.

Pierre Gönczy

Pierre Gönczy obtained his PhD from The Rockefeller University (New York, USA) in 1995 and joined the laboratory of Tony Hyman at the EMBL (Heidelberg, Germany) as a postdoctoral fellow in 1996. He started his own laboratory at ISREC in 2000. In 2005, he became Associate Professor at the EPFL School of Life Sciences, and was promoted Full Professor in 2009.

Cell biology

Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. Cell biology is the study of the structural and functional units of cells. Cell biology encompasses both prokaryotic and eukaryotic cells and has many subtopics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition.

Centriole

In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells, but are not present in conifers (Pinophyta), flowering plants (angiosperms) and most fungi, and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and Ginkgo. A bound pair of centrioles, surrounded by a highly ordered mass of dense material, called the pericentriolar material (PCM), makes up a structure called a centrosome.

Structural biology

Structural biology is a field that is many centuries old which, as defined by the Journal of Structural Biology, deals with structural analysis of living material (formed, composed of, and/or maintained and refined by living cells) at every level of organization. Early structural biologists throughout the 19th and early 20th centuries were primarily only able to study structures to the limit of the naked eye's visual acuity and through magnifying glasses and light microscopes.

Mathematical model

A mathematical model is an abstract description of a concrete system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling. Mathematical models are used in applied mathematics and in the natural sciences (such as physics, biology, earth science, chemistry) and engineering disciplines (such as computer science, electrical engineering), as well as in non-physical systems such as the social sciences (such as economics, psychology, sociology, political science).

Proteomics

Proteomics is the large-scale study of proteins. Proteins are vital parts of living organisms, with many functions such as the formation of structural fibers of muscle tissue, enzymatic digestion of food, or synthesis and replication of DNA. In addition, other kinds of proteins include antibodies that protect an organism from infection, and hormones that send important signals throughout the body. The proteome is the entire set of proteins produced or modified by an organism or system.
