Brief Biography

Dr. Brent Derry received his B.Sc. from Carleton University in 1989, his M.Sc. from McMaster University in 1992, and his PhD from the University of California, Santa Barbara, in 1997. His PhD thesis research with Dr. Leslie Wilson focused on elucidating the molecular mechanism by which the anti-cancer drug taxol suppresses microtubule dynamics, and the role of beta-tubulin isotypes in taxol resistance. Derry carried out his postdoctoral training from 1997 to 2003 in the laboratory of Dr. Joel Rothman at the University of California, Santa Barbara, where he identified and characterized the C. elegans p53 tumour suppressor gene.

In 2003 Derry joined the Research Institute as a scientist. His laboratory is focused on the application of genetics, functional genomics, and biochemical techniques to understand the p53 signaling network.

Research Interests

  • Using C. elegans to model human diseases
  • Mechanisms of programmed cell death (apoptosis)
  • Organ development
  • DNA repair
  • Cellular non-autonomy

Research Activities 

The broad goal of my research is to understand how tumour suppressor p53 integrates various stresses to modulate apoptosis, cell proliferation, development, and genomic stability. We are applying genetics and functional genomics techniques using the model organism Caenorhabditis elegans to identify genes that collaborate with p53 to control these cellular processes. Because C. elegans possesses a single p53 family member, cep-1, analysis is not complicated by the presence of family members p63 and p73, which have been shown to share some overlapping functions in vertebrate systems.

My team and I recently discovered a novel pathway that regulates germline apoptosis in parallel to cep-1 (Ito et al., 2010). This new pathway contains the kri-1 gene, an orthologue of human CCM1/Krit1, which is frequently mutated in the neurovascular disease cerebral cavernous malformations.  Remarkably, kri-1 is required in the somatic tissue to promote apoptosis in the germline by a cell non-autonomous mechanism.  We are utilizing the powerful genetics of C. elegans to delineate this novel pathway and gain insight into how neighbouring tissues regulate the survival of damaged germ cells. 

Current projects in the lab:

  1. Regulation of cep-1 dependent apoptosis.
  2. Non-autonomous control of germline apoptosis.
  3. Regulation of DNA damage-induced apoptosis by the insulin signaling pathway.
  4. Role of cep-1 in maintenance of genome stability.
  5. Role of cerebral cavernous malformation (CCM) genes in apoptosis and organ development.
