Microtubule Severing: A Role In Mammalian Oocyte And Embryo Viability?

Summary
In all cells, cell division is controlled by a microtubule based structure known as the spindle. Abnormal function of this spindle leads to loss and gain of chromosomes that in oocytes causes early embryo loss and in cells of the body it causes cancer and cell death. We will investigate a family of proteins that modify microtubules and explore the role they play in ensuring cell division happnens safely.
The Role Of Clathrin In The Spindle Assembly Checkpoint And As An Anti-cancer Target

Summary
Cell division produces two daughter cells. Incorrect localisation and modification of proteins that regulate mitosis cause errors that can lead to cancer. As well as using a unique machinery mitosis uses proteins involved in non-cell cycle pathways. This project investigates the role during mitosis of one such protein: clathrin. We will identify lead clathrin inhibitory compounds, pitstops, that have potential anti-cancer properties, ultimately to be used as a chemotherapy agent.
Regulation And Mechanisms Of Cell Cycling, Cell Senescence And Cell Death

Summary
Most of our cells are not dividing, but persist in a stable arrested state, yet little is known of the molecular mechanisms that regulate and maintain permanent arrest, or that go wrong when cells start proliferating and turn into cancers. This proposal addresses an area of fundamental, basic biology, that has been largely overlooked. A better understanding of the molecules that regulate cell stability might provide new drug targets so that tumour cell proliferation can be stopped.
Sex Chromosome Instability In Disorders Of Development

Summary
Chromosomes must be copied and distributed faultlessly into the newly dividing cells for normal development to occur. Factors that affect this process are often associated with health problems such as birth disorders, cancer, premature aging and infertility. This project plans to identify genetic factors that compromise the faithful transmission of chromosomes from cell to cell. Results gained from this project will greatly assist in the diagnosis of chromosome-related disorders.
