Research Interests

The process by which a cell divides to produce two genetically identical daughters is called mitosis. During this terminal stage of the cell cycle the replicated chromosomes bind in animals, via their associated sister kinetochores, to microtubules emanating from two replicated and separated centrosomes. This interaction leads to the formation of a transient bipolar apparatus termed the mitotic spindle which is responsible for producing and transmitting the forces for chromosome segregation (karyokinesis) and cleavage (cytokinesis).

Considering that ~ 2.5 X 108 cells are dividing in the human body at any given time, even if few errors occur, many genetically abnormal cells will be produced during the lifetime of an organism.  Some of these will lose their ability to regulate the cell cycle, which is one of the attributes of cancer cells.  An important goal of cancer research is, therefore, to define the molecular mechanisms that form the spindle and generate the forces to accurately distribute the chromosomes.  A more recent focus is to understand how the cell regulates progression into and through the division process. Surprisingly these problems are intimately linked because chromosome motion and progression through mitosis are both governed by the formation of kinetochore fibers. 

The Rieder lab develops and applies sophisticated computer-based three dimensional (3-D) light and electron microscopic (EM) approaches to study the behavior, structure, composition, and function of centrosomes and kinetochores, and how these two organelles interact to form the mitotic spindle and move the chromosomes in vertebrate somatic cells. We are also defining and exploring the cell cycle checkpoint controls that regulate progression through the mitosis portion of the cell cycle, and how these can be used to selectively kill cells.
